The ExtendAir G2 24GHz Digital Microwave Radios
The Exalt ExtendAir G2 24GHz digital microwave radios are the most advanced carrier-class point-topoint terrestrial radio communications devices operating in the 24GHz frequency bands. The
ExtendAir G2 24GHz radios are available with two Gigabit Ethernet PoE ports that are 10/100/
1000BaseT (ETH1/PoE + ETH2).
The ExtendAir G2 24GHz radios connect digital data from one location to another, obviating the need
for copper or fiber connectivity or enhancing existing connectivity by providing a redundancy
solution, a primary solution, and/or additional capacity. Figure 1 and shows the ExtendAir G2 24GHz
digital microwave radio.

configured with 25Mbps of full-duplex Ethernet capacity
The ExtendAir G2 24GHz models require a clear line-of-sight and proper path clearance to achieve a
high-performance, reliable connection. Perform professional path engineering and site planning before
installing this equipment.
The primary focus of this document is the installation and maintenance of the digital microwave radio,
and assumes that path engineering and site planning were already performed.
The ExtendAir G2 24GHz radios utilize radio frequencies that are considered ‘unlicensed’ in most
countries. This means that the frequency plans and radio configuration are not coordinated with other
users of the spectrum. Also, the frequency, channel-center frequencies, occupied bandwidth, and the
Transmitter-to-Receiver frequency separation (also known as T/R spacing) are utilized to allow
maximum use of the 24 GHz unlicensed band. In many bands, it is necessary to offer unique part
numbers to allow coverage of a 'sub-band' of the entire frequency band, and also to address the specific
T/R spacing that is required. The following is a table of the configurations supported.

In most cases, there are regulations or device-based conditions that limit the use of the device, such as
minimum or maximum antenna gain, antenna polarization, and maximum output power, as well as, in
some cases, application limits, limited geography of use, and other unique regulations. The link
design engineer and/or professional installer must determine these limitations and engineer/
install the system within the confines of all local regulations. Also, it is required to examine any
regulations that may apply to peripheral equipment, installation and cabling of the system that may be
regulated for human safety, electrical code, air-traffic control, and other safety-related categories. In
some cases, a need for link registration, coordination, and fees that may apply to the system usage.
Please consult your local regulatory organization(s) to determine usage requirements.
In almost all cases, the product itself must be authorized for use in your country. Either Exalt or Exalt’s
agent must have applied for certification or authorization to allow the sale and deployment of the
system within the country. It is also possible that only certain versions or configurations of the device
are allowed within a particular country. Please contact Exalt or your authorized Exalt representative
for information pertaining to your country.
Note: It is the professional installer’s responsibility to ensure that the radio system is
implemented in a legal fashion. Exalt is not liable for any unsafe or illegal installations.
Basic Features
The ExtendAir G2 24GHz Digital Microwave Radios are intended for all-outdoor mounting and
designed to be used with an indoor-mounted power injector.
For most implementations, the entire unit is typically mounted on a tower or rooftop mast structure,
with Ethernet/Power and other optional interface cables running from the unit location, through a
structure penetration, and to the power injector and connected communications equipment.

Pre-installation Tasks
This section describes the steps necessary to prepare a site for the installation of the Exalt Digital
Microwave Radio.
Link Engineering and Site Planning
Design all terrestrial wireless links prior to purchase and installation. It is best to engage professional
wireless engineering personnel to determine the viability and requirements for a well-engineered link
to meet the users’ needs for performance and reliability.
The link engineering will determine the following attributes:
•
Antenna type/gain at each end of the link
•
Antenna mounting height/location for proper path clearance
•
Antenna system grounding
•
Lightning arrestor type(s), location(s), and grounding
•
Radio mounting location and mechanisms
•
Radio grounding
•
Radio transmitter output power setting
•
Anticipated received signal level (RSL) at each end
•
Anticipated fade margin and availability performance at each end
•
Radio settings for modulation and occupied bandwidth
•
Anticipated throughput performance
With respect to radio path and site planning, these radios are generally identical to other microwave
terrestrial wireless systems. Engineering of these systems requires specific knowledge about the
radios, including:
•
RF specifications (transmitter output power, receiver threshold, occupied channel bandwidth, and
carrier-to-interference tolerance)
•
Regulatory limitations on transmitter output power setting and antenna type/gain
•
Noise/interference profile for the intended location (where applicable)
Familiarization with the ExtendAir G2 24GHz Radios
The ExtendAir G2 24GHz radios utilize frequency division duplex (FDD) radio transmission. This
means that the radio transmits on one center frequency in one direction while simultaneously receiving
on a different center frequency in the opposite direction. This provides full-duplex configuration with
equal capacity in both directions and minimal latency.
The radios are configured in Horizontal (TX-H) and Vertical pairs (TX-V), with alternate frequency
settings for Transmit and Receive on the opposite ends of the link. The internal diplexers can be
configured in the field (for example, to change a TX-H to a TX-V configuration) to ease sparing and
re-configuration.
Exalt recommends using the Exalt GUI for radio configuration. This interface requires a computer
with an Ethernet port and web browser software, such as Microsoft Internet Explorer 11.0 or above.

Shipping Box Contents
The terminals are shipped as individual endpoints. As mentioned, it takes two terminals–one TX-H
and one TX-V–to make a complete link. An outer box has labeling that indicates the contents of the
box, with the part number and serial number details for the radio terminal. The terminal box contains
the following items:
•
Radio terminal
•
Accessory kit (includes reset connector)
•
Registration card
•
Quick-start guide
Power solutions are sold separately. Power for the ExtendAir G2 models comply with the 802.3at
Power-over-Ethernet (PoE) standard. Any 802.3at PoE device is compliant with these models.
You must mount the radio to the proper direct-mount antenna, therefore no mounting hardware is
required.
Inspect the outer packaging and the contents of the boxes upon receipt. If you suspect any shipping
damage or issues with the contents, contact Exalt Customer Care (see Introduction).
Note: Register your system as soon as possible. A 2-year Warranty period applies. See
Exalt Limited Hardware Warranty Software License and RMA Procedures Agreement.
Outdoor-rated and shielded CAT5e or CAT6 cable, such as Belden 1300A, with RJ-45 connectors is
recommended for the Ethernet connections. For Ethernet connections, a maximum length of 100
meters applies to the total length of the cabling between the radio terminal and the first network-aware
connection (such as a switch or router).
Initial Configuration and Back-to-Back Bench Test
Every Exalt digital microwave radio goes through extensive quality testing and performance
evaluation over the full operating temperature range prior to shipment. However, before installation, it
is strongly advised to perform several tests and tasks that are much more difficult to perform once the
radio link endpoints are distant from one another. A back-to-back bench test and pre-configuration will
provide confidence that the radio link is operational and properly configured prior to installation, so
that if troubleshooting is necessary, the radio hardware and configuration settings are eliminated from
the troubleshooting process. Verify the following in the back-to-back testing:
•
•
Confirm that the radio system is generally operational
–
Radios power-up with planned power and wiring solutions
–
Radio firmware version matches on each terminal (and is ideally the latest version)
–
RF link connects in both directions
–
Traffic passes across the link
Configure connected equipment and cabling
–
Test Ethernet (CAT5e) cabling, any auxiliary connector cabling, and configure all interfaces
–
Configure IP settings for configuration and management

–
Configure passwords and security modes
–
Become familiar with the configuration and management interfaces through the Exalt GUI
interface
–
Configure radio parameters
–
Set transmitter output power to engineered or allowed level (see RF Output Power Setting)
–
Set operating center frequency
–
Set occupied channel bandwidth and modulation
Make detailed radio performance measurements
–
Measure transmitter output power
–
Measure receiver threshold performance
–
Confirm unfaded error-free performance
Some of these tasks may not be possible or practical within a bench test environment due to the nature
of the remote connectivity of peripheral equipment. However, it is good practice to perform as much as
possible in this environment to minimize field/installation time and troubleshooting efforts.
Detailed performance measurements are usually not required for pre-installation, but can be easily
performed at this stage and may be helpful for later troubleshooting efforts or for internal records.
During troubleshooting, there may often be a point at which a back-to-back bench test should be
performed to verify many or all of the above items, and in the case of a suspected faulty device, to help
confirm the fault and determine which end of the system is at fault and in need of repair or
replacement.
Note: See Back-to-back Bench Testing for detailed instructions.
RF Output Power Setting
The maximum RF output power is bounded by one of the following criteria:
•
Maximum RF output power setting capability of the radio device
•
Maximum RF output power allowed/authorized by the local government regulations and for this
specific device
•
Maximum effective isotropic radiated power (EIRP) of the transmission system allowed/
authorized by the local government regulations and for this specific device
•
Desired RSL to not exceed the maximum RSL allowed by the device
•
Desired RSL to minimize/eliminate interference into neighboring systems
Note: In many cases the radio must be pre-configured for legal maximum output power
before connecting to the antenna and transmission system. Instructions for adjusting the
output power can also be found in Power.
Critical Configuration Considerations
The ExtendAir G2 24GHz radios are very dynamic, allowing the installer to optimize and control the
performance of the radio system for the intended application. The following parameters must be
carefully determined during the link engineering phase:
209866-002
2015-09-09
Exalt Installation and Management Guide
ExtendAir G2 24GHz Digital Microwave Radios
•
Bandwidth
•
Mode (modulation)
The setting of the above parameters determines the Ethernet throughput.
Use a professional link planning tool to determine optimum settings for the above parameters to meet
the needs of your application.
Note the following generalizations regarding these factors:
•
The higher the bandwidth, the higher the capacity
•
The higher the mode, the higher the capacity
Single IP Architecture
Exalt radios have a single IP architecture. The IP resides on the processor for management
connectivity. If you are planning to use Out-of-Band management (see the Ethernet Interface
Configuration Page), ensure that devices connected to the radio are properly configured. The
management port (typically Ethernet 1) must be completely separate from the traffic (router or switch)
ports. You can achieve this by using a separate switch or configuring a management-traffic specific
VLAN for the radio management port.

ExtendAir G2 24GHz Digital Microwave Radios
Radio Reset
Use the reset function if the IP address and/or passwords are lost. Use the steps particular to your radio
model to perform a critical parameter reset.
The following configurations are reset on the radio when performing a reset:
•
IP address = 10.0.0.1
•
IP mask = 255.0.0.0
•
IP gateway = 0.0.0.0
•
Administration password = password
•
User password = password
•
VLAN = disabled
Performing a Reset
To perform a radio reset, you must have a mechanism to connect the radio’s RSL/BNC port between
the center pin and the shield to provide a “short” between the two conductors. Common methods for
this are:
•
Using the BNC termination provided in the radio accessory kit.
•
Using a standard voltmeter BNC cable, attach a jumper clip to the voltmeter end to short the two
conductors.
•
Using a BNC male connector assembly, connect or solder a wire or jumper to short the center pin
and outer shield.
Once the RSL/BNC port shorting mechanism solution is identified, follow this procedure:
Remove the power source, preferably at the AC or PoE DC input.
Remove the RSL/BNC port cover on the radio.
Install the RSL/BNC port shorting mechanism chosen above.
Apply power.
Wait until the internal beeper sounds (approximately 1 minute). You can verify the reset by
pinging the 10.0.0.1 default IP address.
Remove the RSL/BNC port shorting mechanism.
Replace the RSL/BNC port cover.
Virtual Local Area Network (VLAN)
VLAN segments information in a single connection and creates multiple separate connections to
secure information of one type or for one set of users from other information types or for other sets of
users. Exalt’s VLAN communications implementation adheres to the IEEE standard 802.1q.
In most cases, an Exalt radio acting as a Layer 2 bridge between two locations is only required to pass
traffic with VLAN tagging. Without additional configuration, all Exalt radios support frame sizes in
excess of 1900 bytes, which currently supports all defined VLAN packet sizes.

2015-09-09
Exalt Installation and Management Guide
ExtendAir G2 24GHz Digital Microwave Radios
Note: If an application only requires the transparent passing of VLAN traffic, disable the
VLAN function.
Some situations require Exalt radios to act upon VLAN traffic and perform any or all of the following
functions:
•
Connect specific traffic, using VLAN tagging, to a specific port on the radio, such as management
traffic to the ETH1/PoE port.
•
Allow only traffic with specifically assigned VLANs to pass across the link, blocking all other
VLANs or any non-VLAN traffic.
•
Allow management access only through a VLAN connection, leaving the main traffic transparent.
•
Allow management access without a VLAN connection, but flowing only specific VLAN traffic
across the link.

The Exalt radios primarily use a browser-based graphical user interface (GUI) for radio configuration
and management, as described in Exalt Graphical User Interface (GUI). In addition, a command line
interface (CLI) is provided for SSH or Telnet access, as described in Command Line Interface (CLI).
SNMP is often used for management of larger networks as described here. Use SNMP to manage
networked devices and execute the following functions:
•
GET: Obtain information from the device, such as a configuration setting or parameter.
•
SET: Change a configuration setting on the device.
•
TRAP: The device proactively informs the management station of a change of state, usually used
for critical alarms or warnings.
One feature of the SNMP implementation is that system configuration changes do not take effect using
the SET command. Instead, groups of configuration settings can be preconfigured for global change,
and a single ‘Save’ (Commit) command implements all changes.
When some parameters are changed, a link may drop and/or management control lost. MIB files allow
many parameters to be set at once, allowing only a temporarily dropped link or management control
issue. The opposite end radio can be quickly reconfigured, with little downtime for the link and
management control. The save (Commit) command is similar to the Update button.
Dropped links or management control issues do not occur with every parameter change. Many
configuration changes do not impact traffic or management access.
Exalt radios utilize SNMPv3, a high security version of SNMP, to ensure secure access to and storing
of management data. The SNMPv3 security string matches the admin and user passwords. Passwords
must be eight characters or longer. SNMPv1 and SNMPv2 are also supported.
Note: MIB files downloadable from the radio are listed on the File Transfer Page. You can
also find MIB files for your radio on exaltcom.com. MIBs for Exalt radios are model specific.

Installation
This section presents all tasks required to install the Exalt Digital Microwave Radio.
Mechanical Configuration and Mounting
The ExtendAir G2 24GHz radios are environmentally sealed units intended for deployment outdoors.
The device must be deployed within an ambient temperature range as specified, and with non-restrictive
airflow around the chassis.
Note: Unless otherwise specified by the manufacturer, the power injector and power supply
must be placed indoors or in an enclosure.
Provide proper clearance for all cables and connectors attached to the device.
Mounting the System
You must mount this radio directly to the antenna. The antenna must be the proper type for this to be
accomplished (see Antennas).
Figure 4 Direct-mount configuration
Use the following steps to direct-mount the radio:
Mount the antenna with the proper polarization alignment, following the instructions provided
with the antenna.
Note: You must mount the ExtendAir G2 24GHz with the handle facing up (Figure 4). The
system utilizes both polarizations of the antenna to achieve the full duplex link and cannot
operate properly if the radios are oriented in any other manner.

Power
The radio requires a DC power source within specifications via a power-over-Ethernet (PoE) power
injector (sold separately). Most PoE injectors take a DC voltage source input or use an AC adapter, or
may be integral to a network switch or router.
Note: All injectors used with this product must be 802.3at compliant.
Read this section completely before applying power.
As an alternative to an off-the-shelf 802.3at injector, Exalt provides modular PoE solutions, including
a multi-injector rack mount solution, that can properly power the ExtendAir G2 radio. These modular
injectors (models A300505, A300501, and A300502) provide proper power to the radio, but the
RESET button on these models does not reset the ExtendAir G2 24GHz radio. Pressing the RESET
button has no effect on the radio and causes no harm.
Applying Power
Do not plug the injector into the main power source first. First, verify that the RF connector is properly
terminated (see Power), and then plug in the radio-side connector from the injector to the radio. If the
power source can be turned off using a switch, disable the power, plug the power supply side of the
injector into the power source, and then enable power to the circuit. If the power source cannot be turned
off, plug in to the power input side of the injector to apply power.
Do not apply power using a live RJ45 connector. Connect all RJ45 connectors first, and then
apply power.
Exalt strongly recommends that the power supplies be fused or on a separate breaker to ensure against
over-voltage and/or over-current situations and to provide some form of protection to the radio
electronics and other devices connected to the same supply. In addition, if the power source is subject
to significant spikes or variation, power conditioning is a worthwhile investment, as the quality of the
power source may have a direct impact on the device operation, performance and/or reliability. An
Uninterruptible Power Source (UPS) or other form of battery-backed system protects against brown-out
and black-out conditions, and condition the power presented to the injector.
Evaluate the opportunity for lightning or other similar surges to be present on the powering system,
including the ability for surges to couple to the power wiring system. If an evaluation indicates that there
is a potential likelihood for these conditions to occur, additional surge protection is recommended for
the input power wiring, especially to protect the radio electronics between the injector and the radio.
Ensure that every connection to the device is wired in this manner.
While the configuration for surge suppression or line conditioning is of a different type for each kind of
signal interface, the opportunity for damage to the device, loss of communications and property is
significant. In some cases, there can also be a risk to human life by not protecting against lightning
entering a building through wiring or improper grounding. If you do not have experience in this type of
installation practice, consult a qualified electrician and/or telecoms professional during the installation
and wiring of the equipment.

Exalt Installation and Management Guide
ExtendAir G2 24GHz Digital Microwave Radios
CAT5e or CAT6 Lightning/Surge Protection
To provide for human safety and for the safety of connected network equipment, it is highly
recommended to place a weatherproof lightning suppression device at the egress point where the
CAT5e or CAT6 cable(s) enter the building, shelter, or cabinet.
To protect the radio equipment, install a weatherproof lightning suppression device near the radio for
all connected CAT5e or CAT6 cables. Surge protection for the radio protection is highly
recommended in areas with any opportunity of lightning. Connect the surge protection using a CAT5e
or CAT6 cable no longer than 6'/1m. Ensure that the surge protection device is properly grounded.
Note: Surge protection is not guaranteed to protect the radio equipment for high surges or
direct lightning strikes.
For the Power/Ethernet cable, specific voltage requirements must be met. The following devices are
the only devices currently recommended:
•
Polyphaser IXG-05
•
Transtector ALPU 1101-959
•
Transtector ALPU-1000BT-R
•
Citel C2MJ8-POE-A/SE
•
Transtector 1101-1030
•
Transtector 1101-1080
Use the previously mentioned short CAT5e or CAT6 cable for the connection between the radio and
the first arrestor. Use bulk outdoor-rated CAT5e or CAT6 cable for the longer run between arrestors,
and indoor- or outdoor-rated cable with a standard RJ45 termination for the connection from the egress
arrestor and power injector. The cabling between the radio, through all arrestors, and to the power
injector must follow a straight-wired convention, maintaining standard Ethernet pairing.
Note: Use only outdoor-rated UV-resistant CAT5e or CAT6 cable. The cable that directly
connects to the radio must have an outer diameter between 0.25"/6.35 mm and 0.31"/7.87mm.
Belden 1300A is recommended. Securely hand-tighten all connectors on the ODU to ensure a
weatherproof seal.
Diplexer (Channel Plan) Configuration
The ExtendAir G2 24GHz radio has a unique feature that allows field reconfiguration of the TX-H or
TX-V Tx/Rx orientation. This allows a single spare unit for both TX-H and TX-V configurations.
CAUTION! Removal of the diplexer cover requires special care. The instructions in this
section must be followed precisely to maintain performance and weatherproof operation.
The Exalt Limited Hardware Warranty Software License and RMA Procedures Agreement
may be void if damage to the radio occurs as a result of improper installation.
The transmitter (Tx) and receiver (Rx) tuning is determined by the ID number on the diplexer:
•
ID #871 indicates that the Tx diplexer is in the horizontal orientation (customer part number
E24F732-H).
•
ID #872 indicates that the Tx diplexer is in the vertical orientation (customer part number
E24F732-V).

Diplexer Flip Kit
The diplexer labels aid in determining configuration. With the radio handle at the top, diplexer ID
#871 Tx/Rx port labels read normally. These labels read upside down for diplexer ID #872.
Note: These diplexers have the same frequency range.
•
The Port label indicates the frequency range of the corresponding port (on the underside of the
diplexer). One side is Tx and the other is Rx, depending on how it mounts to the radio.
•
This label also displays the ID number to select on the System Configuration Page.
Note: Since the diplexer cannot be seen without removing the front cover, it is critical that
you change the external labeling if you change the diplexer. Labels are provided in the
Diplexer Flip Kit.
To change the diplexer configuration:
On the antenna-mounting side of the radio chassis, use a 5mm Hex wrench to remove the four (4)
chassis cover screws shown in the following photo.
Use a forceful back-and-forth motion to pivot the two halves of the chassis against each other until
they separate.
Note that the gasket on the center nozzle of the RF section is a tight fit.
CAUTION! Do not place any object between the seams of the chassis to assist with
separation–this will damage the outer diameter gasket.
The picture above shows the radio with the handle at the positioned at top. Use this orientation to
determine diplexer orientation.

Antenna/Transmission System
This section provides guidance to mounting and connecting the RF transmission system, which consists
of the antenna, RF cabling, and RF lightning arrestors. Consult the manufacturer's instructions for
proper mounting, grounding, and wiring of these devices, and for definitive direction. These
manufacturer's instructions supersede any information in this section. See Antennas for a list of
supported antennas.
Initial Antenna Mounting
The antenna must be an exact model recommended by the path and site planning engineer(s). Mount the
antenna at the proper height, mast/mounting location and polarization orientation as determined by the
path and site planning engineer(s). The model type, location, and orientation of the antenna is critical
with respect to achieving proper path clearance, as well as to mitigate external or self- interference from
nearby or collocated systems operating in or near the same frequency band.
Warning! Mount the antenna in a restricted area and in a manner preventing long-term
human exposure to the transmitted RF energy. Consult your government guidelines for
proper signage and/or safe distance considerations for radio equipment.
The antenna structure must be secure and safe with respect to the mounting of the antenna, transmission
system weight, radio housing, and the combined weight of any personnel that may climb or attach to the
structure.
The combined weight of items and forces on the structure must be carefully considered in the design
and construction of the structure. This must include the weight bearing on the structure in the highest
wind conditions possible in the region, and with respect to all objects affixed to the structure.
If additional objects are affixed to the structure in the future, it may be important to evaluate both the
mechanical impact of these planned additions (with respect to wind and weight loading), as well as the
potential impact to RF interference and frequency coordination (if additional radio equipment is
anticipated). This is especially important if future equipment is likely to operate within the same
frequency band.
Once the antenna is mounted, cabled, and aligned, your goal is to never require modification. This prior
planning is important in the path and site planning stages and in construction of the antenna structure.
Follow the antenna manufacturer’s instructions for mechanical mounting of the antenna. Ensure that
there is enough room around the antenna for alignment activities (moving the antenna in vertical and
horizontal arcs), and for the RF transmission line to connect to the antenna connector unobstructed and
within the specified bend radius requirements of the transmission line.
At this point, the antenna mounts should be fully secure to the structure, the feed of the antenna securely
mounted to the antenna (if the feed is a separate assembly), and the azimuth and elevation adjustments
not completely tightened in preparation of the antenna alignment activity. It is a good practice to
connect the transmission line to the antenna connector as early in the process as possible, to reduce the
opportunity for debris or moisture to enter either the antenna connector or the transmission line

connector. Use a connector cover or other temporary measures to ensure that the connector is kept clear.
Take extra care if the antenna is installed during inclement weather to ensure that no moisture gets inside
the antenna connector at any time.
Now the antenna can be aimed in the general direction required for the link. Use a compass, a reference
bearing, binoculars or any other similar device to point the antenna in the direction (generally) of the
far end radio, and then slightly tighten the azimuth and elevation adjustments so that the antenna
maintains its general position and is safe to be left without additional securing. Refer to the Exalt white
paper, Antenna Alignment, for more information on antenna alignment techniques.
Antenna Alignment
Antennas must be installed at both ends of the planned link to commence precision alignment. Refer to
the Exalt white paper, Antenna Alignment.
Antennas are typically aligned using the radio hardware for precise alignment. However, there are many
very useful tools available to aid in this process, inclusive of devices specifically designed for the
purpose of aligning antennas. Some examples are:
•
XL Microwave Path Align-R
•
Teletronics 17-402
Use of these devices may be extremely advantageous as compared to using the radio, because they
employ many unique facilities to aid in this process. Using these tools also makes it possible to align
the antennas before the radio equipment is delivered. However, many installers successfully use the
radios as the means for antenna alignment.
There are two primary facilities when using the radio to align the antenna:
•
RSL voltage test point using a volt meter (recommended)
A voltmeter with a BNC male connector can be directly connected to the RSL connector on the
radio. The RSL test point DC voltage is inversely proportional and numerically calibrated to the
received signal level. The voltage rises as the antennas are less in alignment, and falls as antennas
are more in alignment. The voltage measurement corresponds to the received signal level in
measurements of dBm (a negative number for RSL measurements). For example, an RSL of –
60dBm yields an RSL voltage measurement of 0.60VDC; an RSL of –45dBm measures 0.45VDC.
•
Audio alignment buzzer
Enable the audio alignment buzzer through the Exalt GUI. When enabled, the radio enclosure
emits a sound. The pitch rises when higher (better) levels of RSL are achieved. Align the antennas
until the highest pitch is accomplished. The tone is continuous when the two ends of the radio
system are in communication. Otherwise, the buzzer beeps.
•
Exalt GUI RSL reading indicates the current RSL in dBm.
Note: There is a slight delay in RSL readings in the GUI as the RSL levels change. In this
case, fine alignment can be done in small adjustments allowing a small gap of time so that the
impact of the adjustment on the GUI display catches up to real time.
Note: Only use the browser-based GUI for antenna alignment if there are no other means
available. If this method is required, refer to Exalt Graphical User Interface (GUI). The RSL
reading can be read on a PC or any hand-held computing device that supports an HTML
browser and Ethernet connectivity.

Configuration and Management
This section describes the command line interface (CLI) and Exalt graphical user interface (GUI).
Command Line Interface (CLI)
Exalt Digital Microwave Radios provide a CLI to set key parameters on the system. Use the Ethernet
for a Telnet session over a network connection.
SSH or Telnet into the Command Line Interface (CLI)
Use an SSH or Telnet connection to access the CLI in the Exalt Digital Microwave Radios. Use the
CLI to set key parameters on the system.
Connect to the Radio in a SSH or Telnet Session
Make the SSH or Telnet connection to the radio through the Ethernet port. Use Windows and perform
the following steps:
Open a command prompt or MS-DOS prompt (Start>Run).
Type C:\>Telnet  at the command line:
The default IP address is 10.0.0.1 (for the TX-H radio or after default reset). 10.0.0.2 is the IP
address for a new (from factory) TX-V radio.
Note: The accessing computer must be on the same IP subnet as the radio. The radio has a
DHCP server (enabled by default). If the connecting computer is set to obtain its IP
parameters from DHCP, the radio configures the accessing computer to 10.0.0.3 or 10.0.0.4.
No manual IP configuration is required.
Telnet
Use Telnet when prompted to enter the administration level login and password. The default
administration login is admin and password is password. It is recommended that the default
administration password be reset by changed to prevent unauthorized access.

Exalt Graphical User Interface (GUI)
The Exalt GUI is the primary user interface for configuring and troubleshooting the radio and radio
system. A computer or hand-held device with a conventional HTML browser and Ethernet port is
required. Google Chrome is the preferred browser. Netscape, Mozilla, Microsoft Internet Explorer,
and Firefox are also supported.
Preparing to Connect
If the radios are new, both radios are preconfigured as Tx Lo and Tx Hi with default IP addresses of
10.0.0.1 and 10.0.0.2, respectively. If the radios are not new, the IP addresses and Hi/Lo and diplexer
configurations may need to be changed. The initial priority is to connect to the radio’s management
system to completely configure the radio. Assign the radios different IP addresses, unique to each
radio. There are two ways to change the IP address:
Reset the radio to the critical default factory settings (see Radio Reset).
Connect to the GUI using the default IP address (10.0.0.1 or 10.0.0.2), and change the IP address
through the GUI interface.
Note: To connect to the radio’s Ethernet port and use the GUI interface, the accessing
computer must match the radio’s IP address subnet. It is therefore necessary to either change
the radio’s IP address through the CLI to match the subnet of the computer, or change the
computer’s IP address to match the subnet of the radio (such as, a computer IP address of
10.0.0.10 if trying to connect to a radio set to the factory default IP address of 10.0.0.1).
Make Connections
It is recommended that one radio at a time be configured, on a bench, before taking the radios to the
field for installation. Terminate the RF connector with a 50-Ohm termination or a fixed attenuator of at
least 20dB (see Power).
CAUTION! Do not connect the radios in a back-to-back configuration unless the IP
addresses of the two radios are verified as different from each other.
Note: The IP address subnet of the accessing computer must match the radio’s IP address
subnet to connect using Ethernet.
Once connected to the radio using Ethernet, log in to the Exalt GUI.

•
24
Radio IP address for each end.
–
Each end must have a different IP address and cannot match the accessing computer’s IP
address or any address assigned if radios are part of a larger network.
–
It may be required to change the IP address of the accessing computer after changing the IP
address of the radio so that the IP subnet matches.
–
The radio IP address is listed on the Administration Settings Page.
Verify that the two terminals are opposite channel plans.
–
The product label indicates the frequency band and sub-band of the shipped configuration,
such as ending in 1H or H1 (for Band 1, Hi Tx). The opposite end should be 1L or L1 in this
case (for Band 1, Lo Tx).
–
If the warranty warning label that runs across the seam of the two halves of the chassis is
missing or broken, the internal diplexer may have been adjusted since shipment. Check the
label affixed to the chassis to ensure that it matches the product label. If it does not, the
channel configuration likely matches THIS label instead of the product label. If in doubt,
disassemble the radio to inspect the orientation of the installed diplexer to ascertain the
installed configuration. See Diplexer (Channel Plan) Configuration.

The color of the panel indicates alarm status:
•
Green indicates the system is communicating and all functions are normal
•
Yellow indicates a minor non-traffic affecting alarm condition
•
Red indicates a major traffic affecting alarm condition
The left panel summarizes the alarm conditions of the local radio (the radio that matches the IP
address). The information displayed is the IP address and the endpoint identifier (Radio A or Radio B).
The right panel summarizes the alarm conditions of the remote radio (the radio linked to the local
radio).
Note: The ‘local’ radio might be the near-end or the far-end radio, depending on the
management interface connection. The terms local and remote refer to the orientation of the
radio terminals relative to the IP address you are managing. When making certain changes to
a near-end radio without first making changes to the far-end radio, the link may become
disconnected unless configuration changes are reverted to their original settings. When
making changes that may disrupt the link, always change the far-end radio first, and then
the near-end radio to match.
The Summary Status Section allows the Exalt GUI to be a rudimentary management system. Minimize
the browser window to display just the top bar or the top bar and radio information, and open several
browsers on the desktop. When a window status changes to yellow or red, you can quickly maximize
that window to determine the issues.

Most entries on this page are self-explanatory. The following lists unique or important parameters.
•
Fill in the date and time fields as soon as practical. Events are captured with time/date stamps,
which is valuable information for troubleshooting.
•
Set the Link Security Key to something other than the factory default setting (12 characters, all
zeros) at each end. The link security key must match at both sides of the link. If the security key
remains at the factory setting, the radio link is open to sabotage by a party with the same radio
model. Each link should have a unique security key. If using the same security key for every link
in the network, the radio could link to any other radio with the same security key. This is
problematic in multi-radio networks.
–
Note that the security key must be exactly 12 characters. Any alphanumeric character can be
used. The link security key is case sensitive.
Note: Changing the link security key interrupts transmission until the opposite end is
changed to match. Always change the far-end radio first, and then change the near-end
radio.
•

Reset the admin and user passwords. These passwords should not match. If the admin password
remains at the factory default setting, it provides an opportunity for random reassignment by a

The new password must be entered twice. If the passwords do not match and the Update
button clicked, the password is not changed and remains set to the previous password.
AES (Advance Encryption Standard) can be implemented to provide additional data security for
the wireless link. This function requires an upgrade license key (purchased separately). Both
radios in the link must have a valid AES upgrade license key to implement AES. Different bitlength encryption license keys (for example, 128-bit and 256-bit) are also available, depending on
model type. If the required upgrade license key is present, simply insert a matching hexadecimal
string on both terminals and select the Enable AES On option for AES encryption. Note that
similar to the administration and user passwords, the AES string must be entered twice for each
terminal.

Simple Network Management Protocol (SNMP) Configuration
This page allows the enabling and disabling of the Simple Network Management Protocol (SNMP)
functions. Use SNMP to manage networked devices and execute the following functions:
•
GET: Obtain information from the device, such as a configuration setting or parameter.
•
SET: Change a configuration setting on the device.
•
TRAP: The device proactively informs the management station of a change of state, usually used
for critical alarms or warnings. See SNMP Traps.
Figure 16 SNMP Configuration page
One feature of the SNMP implementation is that system configuration changes do not take effect using
the SET command. Instead, groups of configuration settings can be preconfigured for global change,
and a single ‘Save’ (Commit) command implements all changes.
When some parameters are changed, a link may drop and/or management control lost. MIB files allow
many parameters to be set at once, allowing only a temporarily dropped link or management control
issue. The opposite end radio can be quickly reconfigured, with little downtime for the link and
management control. The save (Commit) command is similar to the Update button.
Dropped links or management control issues do not occur with every parameter change. Many
configuration changes do not impact traffic or management access.
ExtendAir G2 24GHz radios utilize SNMPv3, a high security version of SNMP, to ensure secure
access to and storing of management data. The SNMPv3 security string matches the admin and user
passwords. Passwords must be eight characters or longer.
The SNMP MIBs are organized similar to the GUI. Become familiar with the GUI before using the
SNMP function.

Note: MIB files downloadable from the radio are listed on the File Transfer Page. You can
also find MIB files for your radio on exaltcom.com. MIBs for Exalt radios are model specific.
SNMP v1/v2c/v3 Support Options
Enable the SNMPv1/v2c options to allow entering read and read/write community strings.
Note: Users are encouraged to avoid enabling SNMPv1/v2c support due to known security
loopholes in these protocols.
Enable the SNMPv3 options to allow entering read and read/write user names and passwords. These
entries are de-coupled from the standard radio user names and passwords. SNMPv3 provides full
management security.
SNMP Traps
SNMP traps alert the central network management system with important issues about the radio
system. Trap filters are set on the Traps Configuration page (Figure 17).
Trap support for all versions of SNMP are provided and can be independently enabled. Enter the IP
address to which the traps are directed in the Trap Destination IP Address field. The Ethernet port
designated for management must be connected to the network to allow trap information to reach the
designated IP address. In a bridged network, this may not require special network settings. In a routed
network, the connected router must have a defined path for the IP address.
Figure 17 Trap Configuration page
Note: The Update button must be clicked to save any changes to this page.
The following traps are available:
•
32
Authentication Trap: This is an SNMP standard trap when password information for SNMP is
incorrect. This can help identify unwanted intrusions into the management system and for
diagnosis of SNMP issues for valid users.

•
Radio Reboot Trap: This trap is sent after any radio reboot to inform the manager of the reboot
status.
•
Local/Remote Link Status Trap: This trap is sent when Link is in errored state (equivalent to the
Link LED on the radio front panel or the Link status bar in the upper-left of the Exalt GUI
window).
•
Local/Remote Status Trap: This trap is sent when Status is in errored state (equivalent to the Status
LED on the front panel or the radio status box in the upper-left of the Exalt GUI window).
•
Local RSL Status Trap: This trap is sent when the local RSL drops below the value set in the
Threshold Value (dBm) field. Buffers are provided so that continuous traps are not sent if the RSL
is bouncing near the set threshold value. This trap is reset only if the RSL rises to 3dBm above the
set threshold value and then drops below that value. Exalt recommends that this trap be set to a
value 5dBm or 10dBm above the threshold as a warning that the system has faded and may be
approaching an outage.
•
Temperature Status Trap: This trap is sent when the internal temperature reaches the warning
point. This conveys that the external temperature control is in a fault state. Buffers are applied to
this trap to avoid multiple traps when the temperature remains near the warning point.

File Transfer Page
This page allows the administrator to upload and download files to and from the radio. Two types of
files can be uploaded: configuration, and radio firmware. When uploading Configuration Files,
current configuration parameters are immediately overwritten, and the unit may reboot if
configuration changes require a reboot. When uploading radio firmware files, the file is placed into
reserve memory space. After the new radio firmware file uploads, use the File Activation page to
enable the files (see File Activation Page).
Figure 18 File Transfer page
These types of files can be downloaded: configuration, MIB, Snapshot, and event log. The MIB file
refers to the Management Information Base related to the Simple Network Management Protocol
(SNMP) function, and is only available on models which support SNMP. See Simple Network
Management Protocol (SNMP) Configuration for more information.
Note: Check the File Activation Page before uploading radio firmware files. New file uploads
overwrite the secondary file location. If important files reside in the primary or secondary file
location, download them before uploading the new files. Only the active radio firmware file
can be downloaded. Therefore, to download the reserve file, it must first be activated (using
the Swap button).
Use the following steps to upload a file:
Select the type of file to upload (Radio Firmware or Configuration).

To load the original firmware that shipped with the radio, use the Revert function. Note that reverting
may cause loss of some functionality, as the current firmware may support features not originally
supported.
All other radio configurations are maintained. The radio does not return to factory settings,
just the original factory firmware.
When reverting, the current file moves to an alternate file location and the original factory firmware
becomes current. If you swap back to the original firmware and no new file has downloaded to the
alternate file location, the original alternate file is restored to the alternate file location resulting in the
configuration you started with before you reverted. New firmware always downloads to the alternate
file location, and must be swapped to become the current firmware.
Note: In all cases, the radio reboots after a new file is selected using the Swap function. This
places the radio out of service for a short time.

Most entries on this page are self-explanatory. The following lists unique or important parameters.
•
Set the Diplexer/Filter Configuration parameter to match the installed diplexer of the radio (see
Diplexer (Channel Plan) Configuration).
Note: The diplexer settings for both radios must match.
38
–
871–Use this setting for horizontally oriented diplexers.
–
872–Use this setting for vertically oriented diplexers.
209866-002

ExtendAir G2 24GHz Digital Microwave Radios
These settings constrain the T/R spacing as follows:
Bandwidth
T/R
< 50 MHz
80 MHz.
= 50 MHz
100 MHz.
> 50 MHz
112 MHz.
–
OTHER–Allows any T/R spacing (for example, for RF loopback support). This allows missetting parameters that can result in poor performance or no link. OTHER allows you to set the
T/R spacing as needed to avoid interference.
Note: For optimum performance, base T/R spacings on the bandwidth in use and greater than
or equal to those listed above.
For example, for any bandwidth, a T/R spacing of < 80 MHz results in degraded radio
performance.
–
Use this setting for frequency ranges not available with the diplexer ID.
Note: This setting has no validation process. You must ensure that the proper T/R spacing is
maintained.
If the radio diplexer has never been changed from the manufacture configuration or the change
was done following labeling directions in Diplexer (Channel Plan) Configuration, the label on the
outside of the radio will match the diplexer configuration. If there is any doubt, remove the
diplexer cover to reveal orientation.
•
Set the Radio Transmit Power (dBm) parameter to the designed level. The professional installer
sets this value or dictates the value of this setting to the system administrator following the system
design and local regulations. In many cases, this value must be set to a proper value to comply
with legal restrictions. Improper values can result in liability to the user and/or installer.
Note: Changing Radio Transmit Power may temporarily interrupt traffic. Small changes in
output power do not normally interrupt traffic, but larger changes may.
–
Do not adjust the Radio Transmit Power parameter to a value higher than is legally allowed.
–
Do not adjust the Radio Transmit Power parameter lower than the link budget and fade margin
can afford.
Note: The link may be lost and unrecoverable through GUI control. If the link is lost due
to reduction of Radio Transmit Power, travel to the radio location(s) may be required to reset
the value.

•
Set the Antenna Gain (dB) parameter to compute the Calculated EIRP (dBm).
Note: If you enter an invalid combination of Radio Transmit Power and Antenna Gain, a
regulatory-specific warning appears (ETSI warning shown below) and the out-of-specs field
is highlighted.
Click OK to change the values per regulatory requirements.
•
The read-only Calculated EIRP (dBm) field displays the EIRP based on Radio Transmit Power
and Antenna Gain (for regulatory compliance purposes).
•
Set the Bandwidth (MHz) parameter to the value determined in the design/engineering stage. The
Bandwidth parameter must also match at both ends of the link. In conjunction with the Mode
parameter, the Bandwidth parameter directly relates to the capacity supported.
Note: Changing Bandwidth will temporarily interrupt traffic. The Bandwidth parameter
must match at each end. Adjust the far-end radio first, and then the near-end radio.
Changing Bandwidth changes the radio’s threshold. A wider bandwidth has worse threshold
performance and improved interference immunity, therefore if changing to a narrower
bandwidth, there is an opportunity that the link may be lost and unrecoverable through GUI
control. Check the available fade margin to determine if the impact to threshold and increased
bandwidth is acceptable to maintain the link and the desired performance. If the link is lost
due to increasing the Bandwidth parameter, travel to the radio location(s) may be required to
reset the value.
•
Adaptive Coded Modulation (ACM) allows the radio to reduce throughput as link conditions fall
below what can be supported during normal operation. The advantage is that instead of the link
being down or highly errored, the link remains up for longer periods, but with reduced throughput.
•
ACM Mode parameter enables or disables ACM. Some regulatory environments may not allow
ACM or may require special licensing. Check your local regulations before enabling this feature.
•
ACM Policy parameter selects the modulation to run and how fast to switch between settings.
•
40
–
Aggressive settings switch the radio from modulation to modulation at the moment that the
signal-to-noise ratio allows. This can result in rapidly changing throughput characteristics, but
always provides the highest throughput, even if the currently selected setting is not error-free.
–
Conservative applies hysteresis (that is, the time-based dependence of a system’s output on
current and past inputs) to the switching decision, waiting longer to make a change in the
‘upward’ direction. Switching to a lower modulation is instantaneous, but the radio ‘waits’ to
switch back to a higher modulation state until the signal-to-noise ratio is above the threshold
for that setting. The result is slightly slower changes between modulations and less overall
switching (which could be less disruptive to some network operations).
ACM Base Modulation parameter sets the minimum modulation for the radio to select. There are
cases where regulatory limits may apply that govern the minimum modulation that can be used,
which is sometimes based on licensing. Check your local regulations before deciding this
parameter setting.
209866-002
2015-09-09
Exalt Installation and Management Guide
ExtendAir G2 24GHz Digital Microwave Radios
•
ACM Target Modulation parameter sets the desired modulation for the link under normal unfaded
conditions. The radio attempts to remain in mode at all times, unless link conditions cannot
support it. Again, licensing and/or local regulations may govern the maximum setting for this
parameter.
•
Set the Mode parameter to the designed selection. The value of this setting is determined in the
design/engineering stage and by the licensing process. The Mode parameter must match at both
ends of the link. In conjunction with the Bandwidth parameter, the Mode parameter setting directly
relates to the capacity of the system, as well as critical RF parameters, including receiver
threshold, carrier-to-interference ratio, and in some cases, maximum radio transmit power.
Note: Changing Mode will temporarily interrupt traffic. The Mode setting must match at
each end. Adjust the far-end radio first, and then the near-end radio. Changing Mode changes
the radio’s threshold, carrier-to-interference ratio, and also may have impact on the Radio
Transmit Power. A lower mode has better threshold performance and carrier-to-interference
ratio, and in some cases, higher output power, therefore if changing to a higher mode (for
example, from Mode 1 to Mode 2), there is an opportunity that the link may be lost and
unrecoverable through GUI control. Check the available fade margin and interference profile,
and determine if the impact to RF performance is sufficient to maintain the link and desired
performance. If the link is lost due to increasing the Mode parameter, travel to the radio
location(s) may be required to reset the value.
•
Set the TX Frequency (GHz) parameter and Rx Frequency (GHz) parameter to the center
frequencies. The frequencies must match the same pair at both ends of the link, but in opposite Tx/
Rx orientation.
Note: Changing RF Frequency will temporarily interrupt traffic. The RF Frequency
parameter pair must be opposite at each end. Adjust the far-end radio first, and then the
near-end radio. If the link is lost due to changing the RF Frequency parameter, travel to the
radio location(s) may be required to reset the value.
•
The Transmitter/Receiver (TR) frequency spacing is automatically determined based on the
frequency settings and configured bandwidth in MHz. This is reported to verify the intended
frequency settings, as a confirmation to proper input.
•
Buzzer Timeout (minutes) parameter creates an audio signal for antenna alignment. Turn on the
buzzer continuously during antenna alignment or preset a period of time that the buzzer will
sound. If the buzzer stops before alignment activities are complete, change the selection and press
the Update button or select the ON option until alignment activities are complete.
•
Full-Duplex Throughput parameter provides information about user capacity of the wireless link,
in the current configuration. The ‘new value’ column reflects throughput if changes are made to
Bandwidth or Mode. Click the “Full-Duplex User Throughput” link for details on how capacity
information is determined.

Ethernet Interface Configuration Page
This page allows the administrator to set the muting, alarm, and duplex settings of both the Ethernet
connection and allows determination of the management information for in-band (carried over the air
and available from both Ethernet connectors on either end of the link) or out-of-band (not carried over
the air and only available from the local PoE connector).
Figure 23 Ethernet Interface Configuration page
To ignore Ethernet alarms, disable the alarming of the connector. Muting a connection is desirable
when connected equipment senses Ethernet signaling and makes decisions (such as, spanning tree
protocol enable) based on the Ethernet signal. The ETH1 port cannot be muted, as it is always used for
primary management and PoE.
It may be desirable to disable the alarming of any connector if it is not used.
The Management parameter allows determination of management information using the following
management modes:
•
Inband: Management traffic is carried over the air and is available from all connectors on either
end of the link (Figure 24).
•
Out-of-Band: Management traffic is not carried over the air and is only available from the port(s)
configured for Management.
Note: The port configured for Management and the traffic ports must be logically separated
by using VLANs or a separate switch (see Single IP Architecture).

•
Port-to-Port: Management traffic remains separate from data traffic without requiring out-of-band
management or VLAN configuration. This allows any Ethernet port on the link to be logically
mapped to the same port at the other end of the link without requiring VLANs to be configured.
The traffic passing through these mapped ports is not accessible from any of the other available
Ethernet ports on either side of the link.
•
The Flow Control setting allows the enabling of 802.3 Ethernet flow control. This feature is
selectable on all Ethernet interface ports individually, and enables flow control signaling from the
radio to the connected network device. ‘Pause’ packets are issued when incoming traffic capacity
is greater than current capacity. This feature is only operational when used in conjunction with
Rate Limiting and/or QoS.
•
The Alarm function can be enabled or disabled for each port. Generally, all constantly connected
port alarms should be enabled, and unused or maintenance-only ports should have alarms disabled.
•
The Mute setting allows signaling to connected network devices when the radio link is down such
as for spanning tree protocol.
•
When enabled, the DHCP feature provides a basic DHCP function to ease interfacing with a
computer. DHCP is enabled by default. If the Ethernet port on the computer is set for DHCP
addressing, on radio bootup (for up to 10 minutes) or when an Ethernet link is sensed for a
management port, the radio provides an IP address to the computer that is two digits higher than
the radio’s IP address (for example, if the radio’s IP address is 10.0.0.1, the computer’s IP address
will be 10.0.0.3). The radio also senses any DHCP server on the network and if detected, mutes its
own internal DHCP function.

VLAN is disabled as the default setting for Exalt radios. The Exalt radios still pass VLAN and nonVLAN traffic across the link, but do not examine the VLAN traffic or act upon it. Enable VLAN using
the Exalt GUI for expanded VLAN support.

Note: Once a management VLAN is configured or modified and the Update button clicked,
the management connection will likely be lost. The management connection to the radio must
follow the configuration to the assigned VLAN. After configuring and enabling the
management VLAN on the radio, reconfigure your network’s management access to match
the settings on the radio.
VLAN configurations are maintained even when VLAN is disabled. That is, the VLANs can be
configured and the configuration saved, even though they are not active until VLAN is enabled. Use
the following methods to restore the management connection if a mistake was made assigning the
management VLAN and access cannot be restored: Reset the radio to the critical factory defaults (see

ATPC Configuration Page
Automatic Transmit Power Control (ATPC) is often required by regulatory agencies for radio systems
in congested areas. The radio runs normally at a reduced output power level, and only raises its output
power when necessary, such as during a fade. Regulatory agencies may mandate the transmit power
standards used under normal conditions (set on the System Configuration Page), the maximum
transmit power used with ATPC, ATPC-specific timers, and operator evaluations of the link if and
when mandated conditions are exceeded.
Figure 29 ATPC Configuration page
•
Enable ATPC Mode to allow more radio links to share a spectrum providing less opportunity for
interference.
On the Diagnostic Charts Page, the Far-End Transmit Power chart displays when any combination of
ATPC or Receiver Overload Protection is enabled.
•
ATPC RSL Threshold determines the RSL where ATPC becomes active. When ATPC is enabled,
the far-end transmitter output power is increased to maintain the near-end ATPC receive threshold,
dB-for-dB, as the link fades or recovers. Enable ATPC on both ends of the link for proper
functionality.
•
ATPC Max Tx Power controls the maximum power the radio transmits when ATPC is enabled.
The Radio Transmit Power value shown at the top of this table indicates that entry for ‘normal’
(low transmit power) operation, which is set on the System Configuration page.
•
When the ATPC Timer Control timers are enabled, the ATPC maximum status alarm turns yellow
(minor) when the ATPC timers are exceeded (see Alarms Page). If timers are mandated, set the

ATPC threshold as low as possible to reduce the time that ATPC is active. Current timer status is
available on the ATPC Statistics Page. There are event log entries for all timer events.
•
Receiver Overload Protection is similar to ATPC. It ensures that the maximum RSL is not
exceeded by reducing transmit power of the far-end radio so that radio specifications are met.
Receiver Overload Protection reduces far-end transmit power in un-faded conditions, or during
up-fades, to ensure that the maximum input RSL specification is met at all times and not
overloaded.
Receiver Overload Protection and ATPC can run independently or simultaneously. The radio runs
at standard transmit power levels as long as the Overload Protection RSL threshold is not
exceeded. If exceeded, the radio reduces the far-end transmit power to maintain the target RSL.
For links that normally run at a value exceeding radio specifications, use the maximum output
power in the System Configuration setting and enable Receiver Overload Protection to attenuate
the value for normal conditions and restore output power during fades.
Note: Ensure that radio implementation meets local regulations. There may be limitations to
the use of the Receiver Overload Protection feature. Consult your local regulatory authorities.
•
Set the RSL High Watermark Event Trigger value to a few dB above the normal (un-faded) RSL
link or to a value at or above -33dBm, whichever is higher, to minimize the number of entries in
the event log caused by running at or near the maximum RSL specification.

temperature, so the temperature reading may be higher than the highest specified ambient
temperature. When the internal electronics reach a point that is higher than the normal temperature
rise at the highest ambient temperature, the temperature alarm turns yellow. Power down the radio
as soon as possible, and investigate the cause of the temperature rise before the radio is put back in
service. In almost all cases, a temperature alarm is due to external causes.

Performance Page
This page provides statistical information about the performance of the system in relation to the
integrity of the user data and the RF link.
Figure 31 Radio Performance page
•
The Current BER field indicates the current bit error rate of the link. If the link is operating
perfectly, this should indicate zero. Generally, the link should remain at a BER less than 1x10-6
(one bit out of every million bits errored). This is the threshold performance specification and the
standard to which the link was engineered. However, radio links can and are affected by weather,
interference, and other external sources and will occasionally have a higher error rate. A link
remains operational unless the BER exceeds 1x10-3 (1 bit out of every hundred bits errored).
Consult the link design engineer for an understanding of the predicted error rate of the radio link as
it has been designed.
Many applications are unaffected by bit errors. However, if the link operator is providing a service
guarantee, this value may need to be monitored or examined in cases of service issues. The
behavior of BER in relation to other alarms or measurements and external events can be very
helpful in troubleshooting activities.
•
54
Errored Seconds (ES) indicates the total number of seconds that occurred where there was at least
one bit error since the last time that the radio statistics counter was reset. Generally, ES are not a
significant concern, so long as they are not continuous or above the anticipated performance based
on the original link engineering goals. If ES are continuous or at a high rate, this is normally an
indication of poor link performance due to poor RSL or interference, or severe impact by weather
or other environmental factors. However, similar to the performance factors previously listed, ES
can and will occur in any radio link. Once again, consult the link engineer to determine the original
209866-002
2015-09-09
Exalt Installation and Management Guide
ExtendAir G2 24GHz Digital Microwave Radios
design goals, and compare actual performance to these expectations to determine if any
improvements are necessary or if other problems may be causing excessive ES.
Note: Unavailable Seconds do not register as ES. In other words, the ES counter counts all
seconds that are errored NOT INCLUDING the seconds that were classified as unavailable.
The total number of seconds with errors or outages is the sum of ES and Unavailable
Seconds.
•
Unavailable Seconds (also called UAS) are similar to ES, but this counter keeps track of every
second where the bit error rate equals or exceeds 1x10-3, as well as any seconds where there is a
complete loss of radio communication, over the period since the last counter reset. If Unavailable
Seconds are continuous or at a high rate, this is normally an indication of poor link performance
due to poor RSL or interference, or severe impact by weather or other environmental factors.
However, similar to the performance factors listed above, Unavailable Seconds can and do occur
in any radio link. Consult the link engineer to determine the original design goals, and compare
actual performance to these expectations to determine if any improvements are necessary or if
other problems may be causing excessive Unavailable Seconds.
•
Current RSL is the measurement of the received signal level at the radio antenna port. This is the
measured level of the RF signal coming from the opposite end of the radio link. The link was
engineered to a specific RSL by the link design engineer, and this RSL should be obtained during
installation and remain relatively stable during the operation of the link. RSL can and will vary as
a result of weather changes and other external sources, such as path obstructions. Once again, this
variation was part of the original design to achieve a certain level of performance over time. Bit
errors occur when the RSL falls to a level within roughly 3dB of the threshold specification. When
the RSL falls below the threshold specification, the link disconnects and will not reconnect until
the RSL is above the threshold specification. The behavior of RSL in relation to other alarms or
measurements and external events can be very helpful in troubleshooting activities.
•
Minimum RSL indicates the worst (lowest) received signal level that occurred since the last
counter reset. It is helpful to know if the RSL dropped significantly from the normal level, or has
reached a level near or below threshold.
•
Maximum RSL indicates the best (highest) RSL that occurred since the last counter reset. This
indicates the best performance of the radio link, which is normally equal to the installed value, and
is usually the designed value.
•
Minimum RSL Timestamp indicates the date and time when the Minimum RSL occurred. This is
helpful for general troubleshooting, and especially comparing to items in the event log or
diagnostic charts from the same time period.
•
(ATPC and/or Receiver Overload Protection enabled) Far-End Transmit Power and Max Far End
Tx Timestamp provide an instant record to assist interpretation of the current RSL as it relates to
ATPC and/or Receive Overload Protection actively changing the far-end transmit power. The
timestamp is recorded for the last instance that maximum far-end transmit power initiated.
•
Time Since Reset indicates the amount of time passed since the last counter reset. This helps to
quantify the seriousness of other statistics, such as ES and Unavailable Seconds, if there have been
high numbers of ES and/or Unavailable Seconds over a relatively short period of time.
All end-of-link statistics can be independently reset using the respective reset statistics button. It is
good practice to reset the statistics during link commissioning (after all antenna alignment is complete
and stable RSL at designed levels is achieved, and no more system reboots are anticipated). Regularly
review this page to record performance and reset the statistics so that the counters can more precisely
pinpoint issues.

Data is cleared on a radio power cycle or reload/reset.
The horizontal scale illustrates 120 points of time measurement and is synchronized on all three
graphs. The scale displays in minutes, hours, or days from the last two hours (120 minutes), five days
(120 hours), or four months (120 days). All information is stored, so all of these periods are available
for short- and long-term performance analysis. The right side of a graph represents the most recent
measurement, and data ‘marches’ from the right-to-left at every interval.
The vertical scale of each chart independently scales to show the maximum resolution based on the
maximum variation of the data over the selected time measurement.

indicated by T=(value). This is followed by the value of the measurement, listing the highest value,
lowest value and average value measured over that time interval.
For example, if the displayed time interval is minutes, and the cursor is held at the T=17 mark on the
horizontal axis, the measurements shown indicate performance from 17 minutes ago. The high/low/
average values shown on each chart are measurements made across that specific one-minute interval.
The Far-End Transmit Power chart displays when any combination of ATPC or Receiver Overload
Protection is enabled (see ATPC Configuration Page). This chart shows the far-end transmitter
changes that are occurring relative to the provided RSL information. Since the far-end transmit power
can change on links using ATPC or Receiver Overload Protection, this information is very useful for
troubleshooting.
Changes in RSL often have an impact on BER, and this can be confirmed by looking for synchronized
events. When BER events occur without corresponding changes in RSL, this normally indicates
interference, atmospheric changes, transmission system issues (such as problems with cables,
connectors, or antennas), or possibly radio hardware problems.

This page shows a chart for each Ethernet interface to illustrate inbound and outbound packet
utilization. This is shown as a percentage of the interface configuration (that is, if your interface is set
for 100BaseT, then 100% represents 100Mbps. Compare offered load (inbound) to delivered load
(outbound) to determine if radio capacity is a bottleneck for the data transfer. This chart can illustrate
inbound and/or outbound utilization, and uses different colors for data entry. The legend can be
hidden.

Note that outbound utilization never exceeds the rate where a radio is configured. For example, if the
radio is configured for a 55 Mbps capacity, outbound utilization will never exceed 55 Mbps at
100BaseT.
The Ethernet Utilization Watermark level function allows administrators to receive an SNMP trap
when watermark conditions are exceeded. For example, if a radio is configured for 55 Mbps capacity,
the administrator may wish to be warned if the radio exceeds 50 Mbps for more than 1 hour per day. In
this case, set the Watermark level to 50% and the trap duration to 60 minutes. Traps must be enabled to
activate this function.

Troubleshooting
This section provides information regarding troubleshooting of common issues and alarms on these
radios. Exalt Digital Microwave Radio systems are designed by Exalt’s expert engineers with
extensive experience through multiple generations of microwave radio design. These new-generation
systems contain extensive diagnostic tools, alarm indications, and troubleshooting aids. And, as
compared to other systems in their class, are easier to install, maintain, and troubleshoot. The GUI
provides information to aid in troubleshooting (see Diagnostic Charts Page).
Contact Exalt Customer Care for further assistance with issues with your Exalt radio and with
suggestions on how the radio and documentation can be improved.
General Practices
Troubleshooting a microwave radio link can be a complex task. Approach troubleshooting as a process
of elimination, and first determine which portions of the system are operating properly.
In a vast majority of cases, failures or poor performance of microwave links is attributed to something
other than the microwave radio hardware. In this respect, the back-to-back bench test (see Back-toback Bench Testing) is very important to determine if radio hardware is operating properly and
eliminate many variables in the troubleshooting process.
If a back-to-back bench test fails, then the radio hardware is either broken or the radios are improperly
configured. Upgrade the radio to the most current release of firmware, and/or reset the radio to its
critical factory settings, following the quick start guide instructions and those in Configuration and
Management, helps to confirm if configuration issues cause failure. The most common issues with
microwave radio links are:
•
An improperly terminated antenna or transmission system
•
Multipath propagation
•
RF interference
•
Path obstruction
•
Misaligned antenna
•
Faulty antenna
•
Improper grounding
•
Insufficient link margin in the design/implementation
•
Moisture in the transmission system (antenna feed and/or waveguide)
If the radio link has been operating without issues and is exhibiting new poor performance behavior or
becomes completely inoperative, the troubleshooting process should pay close attention to any
conditions that may have changed between the time when the system was working without issue and
the time when the issues started.
Also, it can be helpful to compare some performance parameters of the system before and after the
presence of issues. Often the source of the issues can be determined by thoughtful consideration of
changes, such as:
•
Changes in weather, including high winds
•
Changes made to the radio equipment, transmission system, or connected equipment
•
New radio systems or electronic equipment the nearby radio or transmission system

•
New construction nearby either end of the link, or along the path
•
Tree growth, flooded fields, or changes in rivers/lakes along the path
Verify that configurations are set as follows:
•
Frequency pair matches (oppositely) at each end of the link
•
Bandwidth matches at each end of the link
•
Ethernet interfaces are enabled, as desired
•
Link security key matches at each end of the link
•
Firmware version matches at both ends
Typical Indications of Issues
In many cases, microwave radio users do not notice changes or degradation to the radio system until
the radio system fails completely or becomes highly errored or significantly intermittent. However,
regular management of the radio system can help indicate changes in performance that have not yet
impacted user performance, but may impact performance at a later date if left unchecked or
unaddressed. The administrator can use this as an opportunity to be proactive and monitor the radio
link performance regularly, watching for unexplained or unexpected changes in performance and
trends in performance changes.
Most importantly, monitoring radio system RSL over time indicates the performance of the radio
system. Address any long-term drop in RSL and erratic or unsteady RSL. Some RSL changes are
expected and weather patterns and the related multipath can cause dramatic RSL changes resulting in
system outage. However, that outage should not occur at a significantly greater rate than the designed
long-term performance. Consult the path design engineer for more information about link reliability
expectations and anticipated RSL deviation.
In addition, regular inspection of the transmission system (RF cables and antennas) and paying close
attention to changes along the path, such as construction or tree height, or new microwave radio
installations nearby, can be extremely helpful and proactive.
When link performance is very poor, alarms on the radio front panel and within the radio’s
management system indicates particular failures. Consult this manual for more information on the
specific alarms and diagnostics, or contact Exalt Customer Care for assistance.
Exalt Customer Care is primarily motivated to determine if the radio hardware is faulty and require
return for repair, and to help execute an effective and efficient repair and return process for radio
terminals believed to be faulty. However, Exalt Customer Care provides advice regarding the total
radio system and RF path engineering and environment, and advises on troubleshooting.
End users should first contact the installer and/or designer of the system. In many cases, an in-depth
understanding of RF design is required, and on-site analysis and special test equipment, may be
necessary. Compared to phone support from Exalt Customer Care, troubleshooting is much more
expeditious if the professional installer and/or link designer examines the system and reviews the
management information in the GUI. In turn, if the professional installer and/or link designer contacts
Exalt Customer Care, the process to rectify the system is much more expedient due to the in-depth
knowledge related to the implementation and the RF environment.
Improper Transmission System
Improper transmission system is a very common problem. In many cases, this is a problem that occurs
during installation and is not a problem that suddenly appears. However, if waveguides are moved or
209866-002
2015-09-09
75
Exalt Installation and Management Guide
ExtendAir G2 24GHz Digital Microwave Radios
flexed and radio errors, changes in RSL or other performance issues occur, this is a certain sign of this
issue.
Another relatively easy method to test for this condition is to decrease the output power of the radio
system (at each end, one end at a time). Poor RF termination may be reflecting too much RF energy
back into the radio system, and reducing output power reduces the reflected energy at a faster rate than
the transmitted energy towards the far end. Be careful not to reduce the output power to the point
where the radio’s threshold is reached. Typically, a reduction of just 3 to 6dB is enough to determine if
this is the issue. If the reduction of output power clears the error condition, this is the likely cause.
Use a reflectometer or meter that can read VSWR at the operating frequency to identify poor
terminations as well as poor antenna feeds.
Multipath Propagation
Multipath propagation is a term that encompasses changes to the RF path, such as reflections and/or
refraction, causing partial or complete destruction of the radio signal, and thus excessive bit errors and/
or system outages.
Rapid changes in temperature, inversion layers, humidity, air pressure, water evaporation, as well as
standing water or moisture on objects along the path are all examples of changes that can cause
multipath propagation. New building construction near either end of the path or along the path can
cause new reflection characteristics.
If your system has been operating without issue and is suddenly experiencing issues that are
symptomatic of a certain time of day or related to change in climatic events or some of the external
factors listed above, this is likely the cause. Consult a professional RF path engineer in these cases.
Often, minor repositioning of the antennas at either or both ends can reduce or eliminate these
problems.
RF Interference
RF interference is usually indicative of another radio system nearby either end of your radio system or
aimed towards one or both ends of your radio system – usually at or near the same frequency and
usually with a similar signal level. This is less common for licensed systems, but still can occur.
Other forms of RF interference also exist, such as electronic equipment placed close to the radio
chassis or transmitters that couple onto the cabling or grounding system of the radio. Microwave ovens
and wireless communication devices used near the equipment or cabling are examples of electronic
equipment interference.
RF interference, like most other causes of problems, is indicated by significant bit errors and/or system
outages.
One means to determine presence of interference is the use of a spectrum analyzer that covers the same
range as the radio system. A professional RF engineer can use a spectrum analyzer to locate sources of
interference, measure these sources, and determine potential remedies to take to operate in the
presence of interference.
If a spectrum analyzer is not available, the radio’s RSL port can help determine RSL levels of
interfering signals. By turning the far-end radio off, the residual RSL measured by the radio indicates
the level of interference seen by the radio. It is possible that interference levels below that which can
be measured still have an impact on the radio system – especially if the radio system has low fade
margin or is using a high order modulation.

Exalt Installation and Management Guide
ExtendAir G2 24GHz Digital Microwave Radios
Changes in frequency, bandwidth, antenna polarization, or antenna position may remedy an
interference issue. However, if the system is licensed, these changes may not be allowed without relicensing.
Path Obstruction
A path obstruction is defined as an object, such as a building or tree, impeding the proper path of the
radio system. If the system design was proper at the time of installation and issues arise at a later date,
an updated path profile and survey may be necessary to identify changes in path clearance.
Misaligned Antenna
At the time of initial installation, it is critical that the antennas at each end are properly aligned and that
the designed RSL is achieved. However, antennas may become misaligned due to high winds, changes
in the guy-wiring systems keeping the antenna mast stable, or loosening of the antenna mounting
hardware. A reduction in the RSL of the link is symptomatic of this condition, but this condition is not
the only condition that results in a reduction of RSL. However, if conditions occur where the antenna
alignment may be suspected, the mechanics must be inspected and the antennas realigned.
Faulty Antenna
A faulty antenna is rare, but is still a possibility. In some cases, the mechanics of the antenna feed can
get moisture inside, or a bad or weak connection in the pin and connector structure of the antenna may
occur. A VSWR measurement of the antenna connection can be made to verify this condition.
Improper Grounding
In addition to being a potential human safety issue, improper system grounding can cause continuous
bit errors or bit errors when metal objects come in contact with the radio, transmission system, or
racking system. If touching the radio causes errors, check the ground connection. Grounding problems
can be difficult to diagnose, but a professional electrician can inspect a system and identify grounding
deficiencies.
Insufficient Link Margin
Ideally, the link was designed with enough link margin (fade margin) to allow for multipath
propagation and atmospheric fading and still remain reliable. In some cases, link margin is
compromised by economic factors, such as using low-cost RF cabling or lower-cost antennas that have
less gain or deficient performance compared to higher cost transmission system components. In some
cases, there may be antenna size restrictions that forced the design to not have the desired amount of
link margin.
If the link was designed with poor link margin, there are likely many cases of bit errors and outages.
The antenna system and transmission line can be upgraded to help reduce this. If the link design was
installed with sufficient margin, but RSL is reduced, the remaining link margin may no longer be
enough to maintain a reliable link. The causes of RSL reduction were previously described, but are
usually due to new path obstruction(s) or antenna misalignment due to wind or mechanical factors. The
antenna height or location can be changed to overcome new obstructions. Realignment of the antenna,
and/or improvement to mechanical structures can help overcome antenna misalignment.
Moisture in the Transmission System
If the connectors on cables and antennas and egress junctions are not properly weatherproofed,
moisture can get into the transmission system and cause significant error conditions and erratic

performance. In many cases, the transmission system must be replaced. A VSWR meter is one means
to identify such issues. Conduct physical inspections often. If changes to the weatherproofing (such as
cracking) are noticed, replace the weatherproofing before leakage occurs.

Back-to-back Bench Testing
Use back-to-back bench testing to test the radio before installation, pre-configure the radio and
connected equipment before installation, or in the troubleshooting process to identify if the radio
hardware is the source of a system issue. It is a critical process, and often required or highly desirable
for any installation or troubleshooting exercise. This section describes how to properly configure the
radio hardware and accessories for a proper back-to-back bench test.
For radio testing, there are two types of back-to-back configurations:
Basic test (general operation)
Specification performance verification
Basic Test
The basic test is a simple test of radio functionality. It verifies that the radios are properly configured to
communicate to one another, and verifies general radio performance as operational.
For the basic test, the following items are needed:
•
Radio pair
•
Powering source
•
RF interconnect cable(s) (any length – short is best)
•
Fixed or variable attenuation, between 60 and 90dB (note: attenuation for basic test does not to be
calibrated or precise)
•
Computer/terminal with either serial or Ethernet port
If no computer is available, use the temporary hardware configuration key or DIP switch,
depending on radio model (see Initial Configuration and Back-to-Back Bench Test)
Connect the items as follows:
Connect attenuation and (known-good) RF cable(s) between radio pair, shown in Figure 42.
Configure the frequencies of the radio to be the same pair, with opposite Tx and Rx orientation.
Power on radio pair

After connecting and powering on and connecting a PC for GUI radio management, verify that the
LINK and STATUS are green. If so, the radios are communicating and all radio-related alarm
conditions are normal. It can be beneficial to have a computer to verify configuration in case of red

LEDs or to pre-configure the radio as desired for operation. Follow the instructions in Configuration
and Management.
Specification Performance Verification
The specification performance verification is a more detailed test that allows you to verify that the
radio’s output power and threshold specifications are being met. This is typically a test that would only
be performed in a troubleshooting scenario, but can be performed before installation to provide a
detailed record or ensure radio performance before installation.
This test is identical to the basic test, but in place of the fixed attenuation, it requires the use of
calibrated variable attenuation, or a set of calibrated fixed attenuators, or a combination of both, adding
to a total attenuation value of 120dB, as measured at the operating frequency of the radio. In addition,
a volt meter or computer is also required.
Connect the system as shown in Figure 42, using the combination of fixed and variable attenuation
between the radio’s RF ports. Connect the volt meter to either radio’s RSL test point and associated
reference ground connection.
In this test, it is desirable to use pre-tested RF cables, known to be good, and the insertion loss is
known at the operating frequency. If the cables are short (6'/2m or less), you can estimate the loss,
including connectors, to be less than 1dB each. The estimate of cable loss is critical to the overall
confidence of the measurements made in this test.
There are two critical specifications that can be tested in this configuration:
•
RF output power
•
Radio receiver threshold
To measure transmitter output power, simply insert any value of attenuation between the radios
between 60 and 90dB. Ensure that both RF output power settings are at maximum. Use the volt meter
to measure RSL in both directions. The RSL measured value should match the appropriate value
according to the inserted attenuation, such as:
RSL = RF Output Power – cabling losses – total attenuation
Verify output power by adjusting output power using the Exalt GUI (in administration mode) and
evaluate the corresponding change to the RSL measurement.
For threshold testing, the key is to insert a measured amount of loss that is close to, but not exceeding
the radio’s specified system gain. System gain is the difference between RF output power and receiver
threshold. At your selected modulation and bandwidth settings, determine the specified threshold
performance, and choose a value of attenuation (including cable losses) that adds to roughly 5 to 15dB
less than the system gain.
For example, if the threshold for your measurement is –85dBm, the output power is +27dBm, so the
system gain is 112dB. Choose a value of total attenuation in the range of roughly 100–105dB. Once
this attenuation is inserted, verify RSL readings as in the first step, and then, using the GUI, reduce
radio output power in 1dB steps until the receiving radio (the one whose output power not being
adjusted) Link LED turns from green to yellow. This indicates that threshold has been reached. At this
point, verify the equation for system gain using the new output power level setting and verify that the
threshold performance is meeting or exceeding the published specification.
Note: Due to the variation of measurements and accuracies involved in this test, you may
read a measurement that is 1dB to as much as 2dB off of the expected value. It should be of
no concern unless the value is more than 3dB worse than expected.

Once threshold is verified in this direction, repeat the process in the opposite direction by adjusting RF
output power of the radio at the opposite end. Return the first radio to its original power setting before
adjusting the second radio.

END USER AGREEMENT
(including Limited Hardware Warranty, Software License and RMA Procedure)
THIS IS AN AGREEMENT BETWEEN YOU (AS ORIGINAL END USER PURCHASER OF AN EXALT PRODUCT)
AND EXALT WIRELESS, INC. ("EXALT"). THE END USER AGREEMENT APPLICABLE TO YOUR EXALT
PRODUCT IS THE END USER AGREEMENT THAT IS PRE-LOADED ON THE EXALT PRODUCT, OR IF NONE IS
PRE-LOADED, IT IS THE END USER AGREEMENT AVAILABLE ON THE EXALT WEBSITE @
WWW.EXALTCOM.COM/EULA ON THE DATE OF YOUR PURCHASE OF THE EXALT PRODUCT OR
OTHERWISE DIRECTLY AVAILABLE FROM EXALT UPON REQUEST. BY ACCEPTING THIS AGREEMENT OR
BY USING THE EXALT PRODUCT WITH OR FOR WHICH THIS AGREEMENT IS PROVIDED ("PRODUCT"),
YOU ARE AGREEING TO ALL OF THE BELOW TERMS AND CONDITIONS. IF YOU DO NOT AGREE WITH
THESE TERMS AND CONDITIONS, YOU SHOULD NOT USE THE PRODUCT AND PROMPTLY RETURN IT TO
YOUR PLACE OF PURCHASE FOR A REFUND. "YOU" MEANS THE LEGAL END USER ENTITY THAT
PURCHASED THE PRODUCT FOR ITS OWN USE.
Exalt Limited Hardware Warranty
a. Exalt warrants solely to the original purchaser ("Purchaser") that the Exalt hardware product
that this Agreement is provided with or for (the "Hardware Product") will substantially
conform in all material respects to the relevant Exalt published specifications that apply at the
time of manufacture of such Hardware Product for two (2) years from the date of purchase of
Hardware Product by Purchaser (the "Warranty Period"). Proof-of-purchase in the form of an
invoice, payment of invoice, or delivery waybill must be supplied, if requested by Exalt, in
case of any dispute of warranty start date.
b. In the event Purchaser notifies Exalt during the Warranty Period of a defective Hardware
Product (material nonconformance with the published specifications), Exalt shall within the
Warranty Period, at its own option either: (A) use reasonable efforts to remedy any
reproducible Hardware Product defect covered by this limited warranty within a reasonable
period of time; (B) replace the defective Hardware Product with a functionally equivalent
product (repair parts and products may be either reconditioned or new, but, if reconditioned,
shall be of the same quality as new parts or products); or (C) if Exalt determines that it is
unable to repair or replace such Hardware Product, Exalt (or its applicable reseller) will refund
to Purchaser the amount actually paid by Purchaser for the applicable Hardware Product. All
replaced parts and products become the property of Exalt.
c. The Exalt warranty does not cover any defective Hardware Product that (i) is subject to the
exclusions set forth below in Section 3; (ii) cannot be demonstrated to have a defect of the
types of defects covered by the Exalt warranty, or (iii) Purchaser is unable to provide adequate
information describing how the Hardware Product failed that would allow Exalt to determine
that the defect is covered by the Exalt warranty. Any Hardware Product that is returned by the
Purchaser to Exalt and Exalt determines that such product is not covered by the Exalt
warranty, will be, at Purchaser's option and expense (including any applicable shipping,
handling, evaluation, repair, replacement and disposal fees), either be: (a) returned to
Purchaser in the state received, (b) repaired or replaced, as applicable, and returned to
Purchaser, or disposed of in accordance with Purchaser's instructions. Repaired or replaced
Hardware Product will be warranted for the remainder of the original Warranty Period, but not
less than ninety (90) days.
