1.2 PRODUCT DESCRIPTION
The GE MDS Mercury SeriesTM transceiver is an easy-to-install wireless
solution offering extended range, secure operation, and multi-megabit
performance in a compact and rugged package. The transceiver is ideally suited for demanding applications in fixed environments, where
reliability and range are paramount.
The transceivers are commonly used to convey text documents,
graphics, e-mail, video, Voice over IP (VoIP), and a variety of other
application data between fixed-point and WAN/LAN-based entities.
Based on multi-carrier Orthogonal Frequency Division Multiplexing
(OFDM), the transceiver features high speed/low latency, basic Quality
of Service (QoS) for prioritizing traffic, Ethernet and serial encapsulation, and network roaming. It also provides enhanced security features
including AES encryption and IEEE 802.1x Device Authentication,
making the Mercury system the best combination of security, range, and
speed of any industrial wireless solution on the market today.
Invisible place holder

case that need only be protected from direct exposure to the weather.
This one enclosure contains all necessary components for radio operation and data communications.
Mercury Reference Manual
05-4446A01, Rev. C
Simple Installation
Mercury Transceivers are designed for rapid and trouble-free installation. For basic services, you simply connect the antennas (3650 MHz
and GPS, as required), connect your data equipment, apply primary
power, and set some operating parameters. No license is required for
operation in the USA, Canada, and many other countries. Check
requirements for your region before placing the equipment into service.
Most installations employ an omni-directional antenna at the Access
Point (AP) location and remote stations. Fixed Remote stations often
employ a directional antenna aimed at the AP. Regardless of the type
used, antennas are a vital part of the system and must be chosen and
installed correctly. Refer to INSTALLATION PLANNING on Page 149
for guidance on choosing suitable antennas and installation sites.
Secure Operation
Data network security is a vital issue in today s wireless world. Mercury
transceivers provide multiple tools to help you build a network that minimizes the risk of eavesdropping and unauthorized access. Some are
inherent in the radio s operation, such as the use of 3650 MHz
spread-spectrum transmissions; others include data encryption,
enabling/disabling channels, and password protection.
Security is not a one-step process that can simply be turned on and forgotten. It must be practiced and enforced at multiple levels,
24 hours-a-day and 7 days-a-week. See GE MDS CYBER SECURITY
SUITE on Page 16 for more information about the transceiver s security tools.
Robust Radio
Operation
The transceivers are designed for operation in the license-free 3650
MHz Industrial, Scientific, and Medical (ISM) band. They provide reliable communications over long distances, even in the presence of weak
signals or interference.
Range depends on many factors, including terrain, building density,
antenna gain, and speed of travel. The unit is designed for successful
application in a variety of environments, and offers the best combination
of range, speed and robustness available in an industrial wireless
package today. By using multiple Access Points, a network can be created that provides consistent, reliable coverage over a large metropolitan
area. See SPECIFICATIONS on Page 162 for more information on
transmission range.
Flexible Services
Users with a mix of equipment having Ethernet and serial data interfaces
can use this equipment via a Remote transceiver. The transceiver provides services in data networks that are migrating from legacy
serial/EIA-232-based hardware to the faster and more easily interfaced
Ethernet protocol.
Flexible
Management
You can locally or remotely configure, commission, troubleshoot, and
maintain the transceiver. Four different modes of access are available:
local RS-232 console terminal, local or remote IP access (via Telnet or
SSH), web browser (HTTP, HTTPS), and SNMP (v1/v2/v3).
05-4446A01, Rev. C
Mercury Reference Manual
The text-based interfaces (RS-232 console, Telnet, and SSH) are implemented in the form of easy-to-follow menus, and the terminal server
provides a wizard to help you configure the units correctly.
Transceiver
Features
The transceiver s design makes the installation and configuration easy,
while allowing for future changes.
¥ Industrial-Grade Product Extended temperature range for
trouble-free operation in extreme environments.
¥ Robust Radio Communications Designed to operate over long
distances in dense, high-interference environments.
¥ Robust Network Security Prevents common attack schemes
and hardware from gaining access or control of the network.
Common attack events are logged and reported by alarms.
• High Speed—1.5 Mbps is over 100-times faster than 9.6 kbps
radios.
• Plug-and-Play Connectivity—AP or Remote configuration
requires minimal setup.
• Built-in GPS Receiver—GPS technology is used for timing and
location data. The only external equipment needed for this functionality is a GPS antenna (several types are available from GE
MDS).
1.2.1 Model Offerings
The transceiver comes in two primary models—Access Point and
Remote. Unique hardware is used for each model. Of the Remote radios,
there are two sub-types available: Standard Remote and Max
Remote, both of which support Ethernet and serial services. Table 1-1
summarizes each radio's interface services.

Access Point or Remote?—Identification Tip
The outward appearance of AP and Remote radios is nearly identical,
however, the hardware for each type is different and they are not interchangeable. An quick way to identify them is to observe the color of the
gasket seal in the center of the radio case. APs have a black gasket,
while Remote units have a yellow gasket.
Mercury Reference Manual
05-4446A01, Rev. C
In addition to gasket color, a label on the top of each radio identifies it
as an AP or Remote unit. If the label shows an —Asuffix, it is an AP. If
it shows a —Rsuffix, it is a Remote.
1.2.2 GE MDS P23 Protected Network (Redundant)
Configuration
For mission-critical applications, a Protected Network Station is also
offered. This unit incorporates two Access Points, two power supplies,
and a switchover logic board that automatically selects between Transceiver A and Transceiver B as the active radio. Figure 1-2 shows the
protected chassis. For system-level information on this product, refer to
MDS publication 05-4161A01.
Invisible place holder
Figure 1-2. MDS P23 Protected Network Station
(incorporates two transceivers, with automatic switchover)
1.2.3 External GPS PPS Option
The External GPS Precise Positioning Service (PPS) option allows for
an external GPS device to provide the PPS input to the Mercury. This is
useful in installations where multiple radios require GPS timing. This
option prevents each Mercury from requiring its own GPS antenna.
Refer to the electrical specifications in the External GPS PPS Option
section on Page 164. This option is only available in hardware revision
1.0.2 or later.
1.3 APPLICATIONS
The following sections provide illustrations of typical transceiver installations. This is an overview only. A Network Administrator should be
involved in all installation planning activities.
05-4446A01, Rev. C
Mercury Reference Manual
1.3.1 Fixed Data System
Mercury transceivers support high-speed data communications in an
industrial environment. In this application, Remote radios roam
between different Access Points, providing seamless transitions and
continuous coverage throughout a municipal area.
1.3.2 Wireless LAN
The wireless LAN is a common application of the transceiver. It consists
of a central control station (Access Point) and one or more associated
Remote units, as shown in Figure 1-4. A LAN provides communications
between a central WAN/LAN and remote Ethernet segments. The operation of the radio system is transparent to the computer equipment connected to the transceiver.
The Access Point is positioned at a location from which it communicates with all Remote units in the system. Commonly, this is a high location on top of a building or communications tower. Messages are
exchanged at the Ethernet level. This includes all types of IP traffic.
A Remote transceiver can only communicate over-the-air to an Access
Point (AP). Peer-to-peer communications between Remotes can only
take place indirectly via the AP. In the same fashion, an AP can only
communicate over-the-air to associated Remote units. Exception: Two
APs can communicate with each other off-the-air through their
Ethernet connectors using a common LAN/WAN.

1.3.4 Serial Radio Network Connectivity
The transceiver provides a path for serial devices to migrate to
IP/Ethernet systems. Many radio networks in operation today still rely
on serial networks at data rates of 9600 bps or less. These networks can
use the transceiver as a means to continue using the serial service, while
allowing the infrastructure to migrate to an IP format.
A Remote transceiver with its serial port connected to a GE MDS
serial-based radio, such as the MDS x790/x710, MDS TransNET and
others, provides a path for bringing the data from the older radio into the
IP/Ethernet environment of a Mercury-based system.

1.3.5 Multiple Protocols and/or Services
Prior to the introduction of Ethernet/IP-based radios, two radios were
often used to service two different types of devices (typically connected
to different SCADA hosts). A Mercury radio provides this capability
using a single remote unit. The unit s serial port can be connected via IP
to different SCADA hosts, transporting different (or the same) protocols. Both data streams are completely independent, and the transceiver
provides seamless simultaneous operation as shown in Figure 1-7.

By using a single radio, the cost of deployment is cut in half. Beyond
requiring only one radio instead of two, the biggest cost reduction comes
from using half of the required infrastructure at the remote site: one
antenna, one feedline, one lightning protector and ancillary hardware.
Other cost reductions come from the system as a whole, such as reduced
management requirements. And above all, the radio provides the potential for future applications that run over Ethernet and IP, such as video
for remote surveillance.
1.3.6 Wireless LAN with Mixed Services
The transceiver is an excellent solution for a long-range industrial wireless LAN. It offers several advantages over commercial solutions, primarily improved performance over extended distances. The rugged
construction of the radio and its extended temperature range make it an
ideal solution even in harsh locations. In extreme environments, a
simple NEMA enclosure is sufficient to house the unit.
The transceiver trades higher speed for longer range. Commercial
802.11a/b/g solutions are designed to provide service to relatively small
areas such as offices, warehouses and homes. They provide high data
rates but have limited range. The Mercury transmits at a higher power
level, uses a different frequency band, has higher sensitivity, and a narrower channel to concentrate the radio energy, reaching farther distances. It is designed for industrial operation from the ground up.
IP-based devices that may be used with the transceiver include new,
powerful Remote Terminal Units (RTUs) and Programmable Logic
Controllers (PLCs). These, as well as other devices, may be used in
applications ranging from SCADA/telemetry monitoring, web-based

1.3.7 Upgrading Older Wireless Network with Serial
Interfaces
Millions of wireless data products have been installed in the last two
decades for licensed and license-free operation, many of them manufactured by GE MDS. There are several ways that these systems can benefit
from incorporating Mercury equipment. The chief advantages are interface flexibility (serial and Ethernet in one unit), and higher data
throughput. By taking advantage of its built-in serial and Ethernet interfaces, the transceiver is well suited to replace leased lines, dial-up lines,
or existing 3650 MHz multiple address data transceivers.
Replacing Legacy Wireless Products
In most cases, legacy radio transceivers supporting serial-interface
equipment can be replaced with Mercury transceivers. Legacy equipment can be connected to the transceiver through the COM1 port with a
DB-25 to DB-9 cable wired for EIA-232 signaling. The COM1 port acts
as a Data Communications Equipment (DCE) port.
NOTE: Several previous GE MDS-brand products had non-standard
signal lines on their interface connectors (for example, to
control sleep functions and alarm lines). These special functions are not provided nor supported by the Mercury transceiver. Consult equipment manuals for complete pinout
information.

1.4 NETWORK DESIGN
CONSIDERATIONS
1.4.1 Extending Network Coverage with Repeaters
What is a Repeater System?
A repeater works by re-transmitting data from outlying remote sites to
the Access Point, and vice-versa. It introduces some additional
end-to-end transmission delay but provides longer-range connectivity.
In some geographical areas, obstacles can make communications difficult. These obstacles are commonly large buildings, hills, or dense
foliage. These obstacles can often be overcome with a repeater station.
Option 1 Using two transceivers to form a repeater station
(back-to-back repeater)
Although the range between fixed transceivers can be up to 40 km (25
miles) over favorable terrain, it is possible to extend the range considerably by connecting two units together at one site in a back-to-back
fashion, creating repeater as shown in Figure 1-9. Use this arrangement
whenever the objective is to utilize the maximum range between stations. In this case, using high-gain Yagi antennas at each location provides more reliable communications than their counterparts
omnidirectional antennas.

Figure 1-8. Typical LAN with a Repeater Link
Overview
Two transceivers may be connected back-to-back through theLAN
ports to form a repeater station. If the transceivers are connected directly
to each other, you must use an Ethernet cross-over cable. This configuration is sometimes required in a network that includes a distant Remote
that would otherwise be unable to communicate directly with the Access
Point station due to distance or terrain.
The geographic location of a repeater station is especially important.
Choose a site that allows good communication with both the Access
Point and the outlying Remote site. This is often on top of a hill,
building, or other elevated terrain from which both sites can be seen
12
Mercury Reference Manual
05-4446A01, Rev. C
by the repeater station antennas. A detailed discussion on the effects of
terrain is given in Section 5.1.2, Site Selection (beginning on Page 151).
The following paragraphs contain specific requirements for repeater
systems.
Antennas
Two antennas are required at this type of repeater station one for each
radio. You must take measures to minimize the chance of interference
between these antennas. One effective technique for limiting interference is to employ vertical separation. In this arrangement, assuming
both antennas are vertically polarized, one antenna is mounted directly
over the other, separated by at least 10 feet (3 meters). This takes advantage of the minimal radiation exhibited by most antennas directly above
and below their driven elements.
Another interference reduction technique is to cross-polarize the
repeater antennas. If one antenna is mounted for polarization in the vertical plane, and the other in the horizontal plane, an additional 20 dB of
attenuation is achieved. The corresponding stations should use the same
antenna orientation when cross-polarization is used.
Network Name
The two radios that are wired together at the repeater site must have different network names. For information on how to set or view the network names, see STEP 3 CONNECT PC TO THE TRANSCEIVER
on Page 23.
TDD Sync Mode
To avoid interference between the two APs that form a repeater station,
they should be synchronized so that they will transmit at the same time
and receive at the same time. This eliminates the possibility of one AP
transmitting while another is trying to receive.
This can be accomplished by setting the TDD Sync Mode parameter in the
Frequency Configuration menu to GPS Required. See Frequency Control
Menu on Page 60 for details.
Option 2 Using the AP as a Store-and-Forward Packet
Repeater
You can extend a wireless network by using the Access Point as a
repeater to re-transmit the signals of all stations in the network. (See
Figure 1-10 on Page 14.)

Figure 1-9. Typical Store-and-Forward Repeater Arrangement
As with the conventional repeater described in Option 1 above, the location of a store and forward repeater is also important. A site must be
chosen that allows good communication with both the Access Point and
the outlying Remote site. This can be on the top of a hill, building, or
other elevated terrain from which all sites can be seen by the repeater
station antenna. A detailed discussion on the effects of terrain is given
in Section 5.1.2, Site Selection (beginning on Page 151).
1.4.2 Protected Network Operation using Multiple
Access Points
Although GE MDS transceivers have a very robust design and have
undergone intensive testing before being shipped, it is possible for isolated failures to occur. In mission-critical applications, down time can
be virtually eliminated by using some, or all, of the following configurations:
In a point-to-multipoint scenario, the Access Point services multiple
remotes. A problem in the Access Point will have an effect on all
remotes, since none will have access to the network. When operation of
the network does not tolerate any down time, it is possible to set up a
protected configuration for the Access Point to greatly reduce the possibility of this occurrence.
Two or more Access Points can be configured identically, each with its
own independent antenna. In this scenario, Remotes will associate with
one of the available Access Points. In case of a failure of that AP, the
Remotes will quickly associate with another Access Point, re-establishing connectivity to the end devices. Because only one Access Point
operates at any given time, collisions between APs is not possible.
1.4.3 Collocating Multiple Radio Networks
Many networks can operate in relatively close physical proximity to one
another provided reasonable measures are taken to assure the radio
signal of one Access Point is not directed at the antenna of the second
Access Point.
14
Mercury Reference Manual
05-4446A01, Rev. C
The Network Name and the Association Process
The Network Name is the foundation for building individual radio networks. Remotes in a network with the same network name as an Access
Point (AP) unit are associated with that AP.
The use of a different Network Name does not guarantee an interference-free system. It does, however, assure that only data destined for a
unique network is passed through to that network.
Co-Location for
Multiple Networks
It may be desirable to co-locate Access Points at one location to take
advantage of an excellent location that can serve two independent networks. Configure each network with a unique Network Name, and
install each AP s antenna with at least 10 feet of vertical separation to
minimize RFI.
To co-locate APs, configure them with Time Division Duplex (TDD)
Sync set to GPS Required. Configure all APs that are within range of each
other with the same pattern, but with a unique Hop Pattern Offset. For
more information, see Frequency Control Menu on Page 60.
NOTE: Transceivers are shipped with the Network Name set to
MDS-Mercury as a factory default.
Can radio frequency interference (RFI) disrupt my wireless
network?
When multiple radio networks operate in close physical proximity to
other wireless networks, individual units may not operate reliably under
weak signal conditions and may be influenced by strong radio signals on
adjacent bands. This radio frequency interference cannot be predicted
with certainty, and can only be determined by experimentation. If you
need to co-locate two units, start by using the largest possible vertical
antenna separation between the two AP antennas on the same support
structure. If that does not work, consult with your factory representative
about other techniques for controlling radio frequency interference
between the radios. (See A Word About Radio Interference on
Page 156 for more details.)
1.5 GE MDS CYBER SECURITY SUITE
Today, the operation and management of an enterprise is increasingly
dependent on electronic information flow. An accompanying concern
becomes the cyber security of the communication infrastructure and the
security of the data itself.

2.1 OVERVIEW
GE MDS recommends that you set up a tabletop network to verify the
basic operation of the transceivers. This allows experimenting with network designs, configurations, or network equipment in a convenient
location. This test can be performed with any number of radios.
When you are satisfied that the network is functioning properly in a
benchtop setting, perform the field installation. Complete information
for field installation, including mounting dimensions and antenna selection, is provided in INSTALLATION PLANNING on Page 149.
NOTE: It is important to use a Network Name that is different from
any currently in use in your area during the testing period.
To simulate data traffic over the radio network, connect a PC or LAN to
the Ethernet port of the Access Point and PING each transceiver several
times.
2.2 STEP 1 CONNECT THE
ANTENNA PORTS
Figure 2-1 shows the tabletop arrangement. Connect the antenna ports
of each transceiver as shown. This provides stable radio communications between each unit and prevents interference to nearby electronic
equipment.

NOTE: Use attenuation between all units in the test setup. The amount
of attenuation required depends on the number of units tested
and the desired signal strength (RSSI) at each transceiver
during the test. In no case should a signal greater than —50 dBm
be applied to any transceiver in the test setup. GE MDS recommends an RF power output level of +20 dBm from the AP.
Remote power is not setable. (See Radio Configuration
Menu on Page 58.)
2.3 STEP 2 CONNECT THE PRIMARY
POWER
The primary power at the transceiver s power connector must be within
10.5—30 Vdc and be capable of continuously providing 30 Watts. Typical power consumption for 13.8 Vdc and 24 Vdc operation are listed in
SPECIFICATIONS on Page 162.
A Phoenix two-pole power connector with screw-terminals is provided
with each unit. Strip the wire leads to 6 mm (0.25"). Be sure to observe
proper polarity with the positive lead (+) on the left and negative (—) on
the right, as shown in Figure 2-2.
NOTE: The transceiver typically requires about 30 seconds to power up, and
might require several minutes to associate with another unit, if GPS
is required for time synchronization.
GPS is required for all configurations except when Free Run
single-channel (non-frequency hopping) operation is used, which
might be possible in some low-interference environments.
CAUTION

2.4 STEP 3 CONNECT PC TO THE
TRANSCEIVER
Connect a PC s Ethernet port to theLAN port using an Ethernet crossover cable. The LAN LED should light. Alternatively, you can use a
serial cable to connect to the COM1 port (Figure 2-3 on Page 25).
2.5 STEP 4 REVIEW TRANSCEIVER
CONFIGURATION
2.5.1 Getting Started
Start by logging into the Access Point radio. This is done first because
the Remotes are dependent on the AP s beacon signal to achieve an
associated state.
Once the Access Point is up and running, move the computer connection
to each of the Remote units, log-in at each unit, review their configuration, set their IP addresses, Network Name, and frequency configuration, then wait for each AP to achieve an associated state.
With all units associated, you will be ready to connect and test your data
services.
2.5.2 Procedure
The following is a summary of the configuration procedure that must be
done on each unit in the system. Key parameters are shown on the
Embedded Management System overview (Figure 3-1 on Page 32). A
lists of parameters is located in two tables Table 4-5 on Page 140 and
Table 4-7 on Page 142. Detailed information on using the Management
System can be found in MS INTRODUCTION on Page 31.
NOTE: The Management System supports the use of configuration
files to help consistently configure multiple units. These are
explained in Configuration Scripts Menu on Page 119.
2.5.3 Basic Configuration Defaults
Table 2-1 provides a selection of key operating parameters, their range,
and default values. All of these are accessible through a terminal emulator connected to the COM1 serial port or through a Web browser connected to the LAN port (see Figure 5-1 on Page 149 for hookup).
NOTE: Access to the transceiver s Management System and changes
to all parameters requires entering a security password.

A unique IP address and subnet are required to access all IP-based management interfaces (telnet, SSH, SNMP, and Web), either through the
LAN port or remotely over-the-air.
2.6 STEP 5 CONNECT LAN OR
SERIAL DATA EQUIPMENT
Connect a local area network to the LAN port or a serial device to the
COM1 (DCE) port. The LAN port supports any Ethernet-compatible
equipment. This includes devices that use Internet Protocol (IP).
Figure 2-3 on Page 25 shows the interface connectors on the front panel
of the transceiver.
NOTE: The use of shielded Ethernet cable is recommended for
connection to the radio sETH port. The radio meets regulatory
emission standards without shielded cable, but shielding
reduces the possibility of interference in sensitive environments, and is in keeping with good engineering practice.

3.1 MS INTRODUCTION
The transceiver s embedded management system is accessible through
the COM1 (serial) port, the LAN (Ethernet) port, and using over-the-air
Ethernet. Telnet, SSH, HTTP/HTTPS, and SNMP are the
Ethernet-based interfaces. Essentially, the same capabilities are available through any of these paths.
For support of SNMP software, a set of MIB files is available for download from the GE MDS Web site at www.GEmds.com. An overview of
SNMP commands can be found at SNMP Agent Configuration section
on Page 53 of this manual.
The transceiver s Management System and its functions are divided into
seven functional groups as listed below.
¥ Section 3.3, BASIC OVERVIEW OF OPERATION (beginning
on Page 40)
¥ Section 3.4, CONFIGURING NETWORK PARAMETERS
(beginning on Page 43)
¥ Section 3.5, RADIO CONFIGURATION (beginning on Page

on Page 85)
¥ Section 3.13,PERFORMANCE OPTIMIZATION (beginning on
Page 127)
¥ Section 3.12, MAINTENANCE/TOOLS MENU (beginning on
Page 113)
Each of these sections has a focus that is reflected in its heading. The
section you are now reading provides information on connecting to the
Management System, how to navigate through it, how it is structured,
and how to perform top-level configuration tasks. Figure 3-1 on Page 32
shows a top-level view of the Management System (MS).
3.1.1 Differences in the User Interfaces
Although there are slight differences in navigation among the user interfaces, the content is very similar. You will notice a few differences in
capabilities as the communications tool is driven by limitations of the
access channel. Figure 3-2 and Figure 3-3 on Page 33 show examples of
the Starting Information Screen as seen through a console terminal and
a web-browser, respectively.

3.2 ACCESSING THE MENU SYSTEM
The radio has no external controls or adjustments. All configuration,
diagnostics, and control is performed electronically using a connected
PC. This section explains how to connect a PC, log into the unit, and
gain access to the built-in menus.
05-4446A01, Rev. C
Mercury Reference Manual
33
3.2.1 Methods of Control
Access the unit s configuration menus in one of several ways:
¥ Local Console This is the primary method used for the examples in this manual. Connect a PC directly to the COM1 port
using a serial communications cable and launch a terminal communications program such as HyperTerminal (found on most
PCs by selecting Start>>Programs>>Accessories>>Communications>>HyperTerminal). This method provides text-based access to
the unit s menu screens. Console control is a hardware-based
technique, and is intended for local use only (maximum recommended cable length of 50 ft./15 m).
¥ Telnet or SSH* Connect a PC to the unit sLAN port, either
directly or via a network, and launch a Telnet session. This
method provides text-based access to the unit s menu screens in
a manner similar to a Local Console session. You can run Telnet
sessions locally or remotely through an IP connection.
¥ Web Browser* Connect a PC to the unit sLAN port, either
directly or via a network, and launch a web browser session (for
example, Internet Explorer, Firefox, etc.). Enter the IP address
of the device to be managed into the browser s address field.
This method provides a graphical representation of each screen,
just as you would see when viewing an Internet web site. The
appearance of menu screens differs slightly from other methods
of control, but the content and organization of screen items is
similar. Web browser sessions may be run locally or remotely
using an IP connection.
When connecting directly to a radio, a crossover cable is required. When
connecting using a network, switch, or router, a straight-through cable is required.
3.2.2 PC Connection and Log In Procedures
The following steps describe how to access the radio s menu system.
These steps require a PC to be connected to the unit sCOM1 or LAN port
as shown in Figure 3-4 on Page 35.

05-4446A01, Rev. C
associated screen where settings may be viewed or changed. In most
cases, pressing the ESCAPE key moves the screen back one level in the
menu tree.
In general, the top portion of menu screens show read-only information
(with no user selection letter). The bottom portion of the screen contains
parameters you can select for further information, alteration of values,
or to navigate to other submenus.
NOTE: Early versions of PuTTY might not operate when using SSH
to connect to the transceiver. The latest version (0.60 at the
time of publication) does work with the transceiver s internal
server. Both the latest released and the latest development
snapshot can be downloaded from:
www.chiark.greenend.org.uk/~sgtatham/putty/.
When you arrive at a screen with user-controllable parameter fields, you
select the menu item by pressing an associated letter on the keyboard. If
there is a user definable value, the field will clear to the right of the menu
item and you can type the value you wish to use. Follow this action by
pressing the ENTER key to save the changes. If you make a mistake or
change your mind before pressing the ENTER key, simply press ESCAPE
to restore the previous value.
In some cases, when you type a letter to select a parameter, you will see
a prompt at the bottom of the screen that says Choose an Option. In these
screens, press the keyboard sSPACEBAR to step through the available
selections. When the desired option appears, press the ENTER key to
choose that selection. In some cases, you can change several parameters
and then save them with a single keystroke. Use the ESCAPE key to
cancel the action and restore the previous values.

VLAN Status
Mercury Reference Manual
05-4446A01, Rev. C
VLAN Configuration Menu
The VLAN Configuration menu (Figure 3-13) becomes active and visible when you enable VLAN Status on the Network Interface Configuration Menu, and you press the Enter key.
CAUTION:The VLAN Status parameter must be consistent at both the
Access Point and Remote radios in order for data to flow
correctly. Failure to do so might result in data not being transported correctly even when the radios are in an associated state
and able to communicate over-the-air.
About Virtual LAN in
Mercury
A VLAN is essentially a limited broadcast domain, meaning that all
members of a VLAN receive broadcast frames sent by members of the
same VLAN but not frames sent by members of a different VLAN. For
more information, refer to the IEEE 802.1Q standard.
The transceiver supports port-based VLAN at the Ethernet interface and
over the air, according to the IEEE 802.1Q standard. When VLAN Status
is enabled, the wireless port of both AP and remote radios act as a trunk
port.
The Ethernet port of an Access Point radio is normally configured as a
trunk port. This type of port expects incoming frames to have a VLAN ID
tag and sends outgoing frames with a VLAN tag as well.
The Ethernet port of a Mercury radio can be configured as an access port
or as a trunk port.
When the Ethernet port of a Mercury radio is configured as VLAN
Access Port, the radio tags incoming traffic with a VLAN ID, and strips
the tag before sending traffic out. This VLAN is known as the DATA
VLAN. Additionally, a second VLAN is assigned for other traffic that
is terminated at the radio, such as SNMP, TFTP, ICMP, Telnet, and so
on. This is known as the MANAGEMENT VLAN. Traffic directed to
the integrated terminal server that handles the serial ports is assigned to
the DATA VLAN.
When the Ethernet port of a remote radio is configured as a VLAN
trunk, the radio expects all incoming Ethernet frames to be tagged, and
passes all outgoing frames as received from the wireless link, with the
unchanged VLAN tag.

Defines whether the radio handles Ethernet
frames in extended 802.1Q mode or in normal mode in the

configured as an Access Port.

DHCP Server
Configuration
(Data and Mgmt)
A transceiver can provide automatic IP address assignments to other IP
devices in the network by providing DHCP (Dynamic Host Configuration Protocol) services. This service eliminates setting an individual
device IP address on Remotes in the network, but it requires some planning of the IP address range. One drawback to network-wide automatic
IP address assignments is that SNMP services might become inaccessible as they are dependent on fixed IP addresses.
You can make a network of radios with the DHCP-provided IP address
enabled or with DHCP services disabled. In this way, you can accommodate locations for which a fixed IP address is desired.
NOTE: There should be only one active DHCP server in a network. If
more than one DHCP server exists, network devices might
randomly get their IP address from different servers every time
they request one.
NOTE: Combining DHCP and IEEE 802.1x device authentication
might result in a non-working radio if the DHCP server is
located at a Remote radio. If possible, place the DHCP server
at the AP location.
A DHCP server can be run at a Remote, but it is not recommended if 802.1x Device Authentication is in use and if the AP
gets its IP address from the DHCP server on the Remote. In
this case, the Remote cannot authenticate to allow the AP to
get its address, because the AP needs an address to perform
802.1x device authentication. This results in an unsolvable

3.4.2 Ethernet Port Configuration Menu
The transceiver allows for special control of the Ethernet interface, to
allow traffic awareness and availability of the backhaul network for
redundancy purposes.
NOTE: The transceiver s network port supports 10BaseT and
100BaseT connections. Confirm that your hub/switch is
capable of auto-switching data rates.
To prevent excessive Ethernet traffic from degrading performance, place the transceiver in a segment, or behind routers.

3.4.4 SNMP Agent Configuration
The transceiver contains over 100 custom SNMP-manageable objects as
well as the IETF standard RFC1213 for protocol statistics, also known
as MIB II. You can use off-the-shelf SNMP managers to access the
transceiver s SNMP Agent s MIB, such as Castle Rock Computing
SNMPc“ and Hewlett Packard OpenView“. The transceiver s SNMP
agent supports SNMPv1, v2, and v3.
The objects are split into nine MIB files for use with your SNMP manager. There are textual conventions, common files, and specific files.
This allows the flexibility to change areas of the MIB and not affect
other existing installations or customers.

In addition, some management systems might require that you
compile the MIB files in the order shown above.

SNMPv3 password used for Authentication (currently, only
MD5 is supported). This string can contain up to 30
alpha-numeric characters.
V3 Privacy Password Privacy password stored in flash memory.
Used when the SNMP Agent is managing passwords locally (or
initially for all cases on reboot). This is the SNMPv3 password
used for privacy (DES encryption). This string can contain
between 8 and 30 alpha-numeric characters.
SNMP Mode This specifies the mode of operation of the radio s
SNMP Agent. The choices are: disabled, v1_only, v2_only,
v3_only, v1-v2, and v1-v2-v3. If the mode is disabled, the Agent
does not respond to any SNMP traffic. If the mode is v1_only,
v2_only, or v3_only, the Agent responds only to that version of
SNMP traffic. If the mode is v1-v2 or v1-v2-v3, the Agent
responds to the specified version of SNMP traffic. [v1-v2-v3]
