The FCC does not require licensing to implement this device. License-free operation in the industrial,

scientific, and medical band is documented in FCC Rules Part 15.247. It is the responsibility of the

individuals designing and implementing the radio system to ensure compliance with any pertinent FCC

Rules and Regulations. This device must be professionally installed.

Exposure to Radio Frequency Fields

The TRACER 6420 is designed to operate at 5.8 GHz with 100 mW maximum transmit power.

This level of RF energy is below the Maximum Permissible Exposure (MPE) levels specified in FCC OET

65:97-01. The installation of high gain antenna equipment in the system configuration may create the

opportunity for exposure to levels higher than recommended for the general population at a distance less

than 15 feet (4.6 meters) from the center of the antenna. The following precautions must be taken

during installation of this equipment:

• The installed antenna must not be located in a manner that allows exposure of the general population to

the direct beam path of the antenna at a distance less than 15 feet (4.6 meters). Installation on towers,

masts, or rooftops not accessible to the general population is recommended; or

• Mount the antenna in a manner that prevents any personnel from entering the area within 15 feet (4.6

meters) from the front of the antenna.

• It is recommended that the installer place radio frequency hazard warnings signs on the barrier that

prevents access to the antenna.

• Prior to installing the antenna to the TRACER output, make sure the power is adjusted to the settings

specified in section 2 of this manual.

• During antenna installation, be sure that power to the TRACER equipment is turned off in order to

prevent any energy presence on the coaxial connector.

• During installation and alignment of the antenna, do not stand in front of the antenna assembly.

• During installation and alignment of the antenna, do not handle or touch the front of the antenna.

These simple precautions must be taken to prevent general population and installation personnel from

exposure to RF energy in excess of specified MPE levels.

Verify the antenna installation meets all regulations specified in the National Electric

Code (NEC) Article 810.

Section 1 System Description TRACER 6420 System Manual

1. SYSTEM OVERVIEW

The TRACER 6420 provides license-free scalable connectivity for service providers and corporate

networks. These radios feature two modular network interface ports that can accommodate various

combinations of T1 and Ethernet option cards up to 8xT1 (16.384 Mbps). This flexibility provides

customized TDM and packet solutions for voice and data applications in a single platform. The

TRACER 6420 radios provide carrier class point-to-point connectivity up to thirty miles in the 5.8 GHz

license-free Industrial, Science, and Medical (ISM) band.

Complete network management is supported via SNMP, Telnet access, and a VT100 craft port. SNMP

traps are implemented for all RF link and T1/Ethernet alarm conditions, enabling remote installations to

report outages without requiring a truck roll to diagnose problems. Version 2 standard MIBs are supported

for all interface cards, while an enterprise-specific MIB is provided for radio functionality. Triple-DES

security provides additional protection from unauthorized access without requiring any additional external

security appliances. Encryption can also be disabled altogether. Future upgrades and enhancements can be

added through FLASH firmware downloads via TFTP (on the Ethernet interface) or XMODEM on the

craft port.

Receive sensitivity is optimized through the use of extensive forward error correction and

high-performance receiver design techniques. Dynamic receive sensitivity allows the user to increase

receiver performance by decreasing the delivered bandwidth. This feature maximizes link performance by

customizing the delivered bandwidth to the specific needs of the installation. Three software selectable

channel plans are supported to simplify frequency coordination at co-located sites. Channel plans are

easily changed via any of the software management interfaces without the added expense of hardware

upgrades or spare filter assemblies.

TRACER wireless solutions maximize equipment density through the combination of compact size (only

1U rack space required), low power consumption, and high thermal transfer. TRACER systems can be

deployed at twice the density of other available wireless products.

1. LINE-OF-SIGHT

The TRACER 6420 system is designed for operation in the license-free 5.725 GHz to 5.850 GHz

industrial, scientific, and medical (ISM) band. Radio wave propagation in this band exhibits microwave

characteristics which are ideally suited for point-to-point, line-of-sight communications. Line-of-sight

requires that the transmitting antenna and receiving antenna are able to “see” each other, and that the

straight-line path between the two antennas is free of obstructions such as buildings, trees, mountains, and

in longer paths, even the curvature of the earth. For maximum signal strength, the area around the visual

line-of-sight where microwave signals reflect (Fresnel zone) must also be free of obstructions. Fresnel

zones are discussed in more detail on page 21.

Terminology

2. DECIBELS

Understanding the decibel (dB) format is key when discussing microwave path engineering because the

received signal power is often expressed in decibel format. In general, any quantity can be expressed in

decibels. If the quantity x is a power level (in Watts), the decibel equivalent is defined as

If the quantity x is referenced to a milliwatt (mW), then the decibel-milliwatt (dBm) is used instead of a

generic decibel.

Using the decibel format simplifies power calculations by reducing multiplication and division operations

into addition and subtraction operations.

3. CALCULATING THE FADE MARGIN

The fade margin (F ) is a value in decibels (dB) that represents the amount of signal reduction that can be

tolerated before the link exceeds the specified bit error rate (BER). Fade margin is simply the difference

between the available signal power at the receiver (PR ) and the receiver sensitivity (Psens ).

Point-to-Point Wireless communication from a single site to another individual

site. Contrast with point-to-multipoint.

Line-of-Sight An unobstructed, direct path exists between the transmitting and

the receiving antennas.

It is imperative to determine whether the proposed microwave path is suitable (at a

minimum) for ideal, nondistorted signals before attempting installation.

Higher levels of fade margin indicate stronger protection against signal fading and a more reliable link. For

most applications, 20 to 30 dB of fade margin should ensure a reliable link.

The following sections further discuss the necessary power calculations and their components.

4. RECEIVER POWER

The viability of a particular microwave path is determined by the power of the transmitted microwave

signal, the transmit and receive antenna gain, distance, and accumulated system losses (such as RF coaxial

cable losses and path loss).

The equation relating received signal power to the other microwave parameters is

or (in decibel notation)

Figure 1 illustrates a wireless link configuration containing all the parameters necessary for the power

budget analysis.

Figure 1. Example Microwave Path with Parameters

The following sections further discuss the power budget analysis and its components.

Antenna Gain

Actual transmit and receive antenna gain values depend strictly upon the physical characteristics of the

antennas installed for each link. In other words, the size of the dish determines the antenna gain. Using a

parabolic dish antenna results in the best performance. Antenna gains are specified in terms of decibels of

gain referenced to an isotropic source (dBi). An isotropic source is a hypothetical antenna having equal

radiation in all directions. Typical antenna gains are listed in Table 1; however, dish manufacturers can

provide gains for specific types of antennas.

Transmitted Power (PT)

The FCC specifies the maximum transmitter power used for antennae of a given gain. FCC Rules (Part 15,

Subpart 247) allow for a maximum transmit power of 1 Watt (30 dBm). Since the TRACER 6420

maximum transmit power is 100 milliwatts, there is no reduction in transmitter output power required.

TRACER 6420 System Manual Section 2 Microwave Path Engineering Basics

Carrier Wavelength (λ)

The carrier wavelength is the physical wavelength of the main RF carrier being used for communication,

and is usually approximated at the center frequency of the band (which is 5787.5 MHz for the

TRACER 6420). The carrier wavelength calculations follow:

λ = c / f (meters)

where

c = speed of light (in meters)

f = frequency (in Hz)

resulting in the following carrier wavelength:

λ = 3.00 x 108 / 5787.5 x 10 5

= 0.0518 m or 5.18 cm

Path Distance (d)

The path distance is simply the physical distance between the transmit and receive antennas. For the

TRACER 6420, these distances can range up to 30 miles.

System Losses (L)

System losses are defined by RF coaxial cable loss, connector losses, and losses added from any additional

lightning protection devices for the power budget analysis. Coaxial cable is required to attach the

TRACER 6420 to the antenna. The length of the cable varies from a few feet to hundreds of feet,

depending upon your application and the proximity of the TRACER 6420 to the antenna. Various grades

of coaxial cable will work sufficiently well for connecting the TRACER 6420 unit to the antenna. A

low-loss coaxial cable will minimize cable losses.

One end of the coaxial cable requires an N-type male connector (plug) to mate with the TRACER 6420

unit. The other end of the coaxial cable requires a connector compatible with the antenna chosen for the

installation (usually an N-type male connector). Additionally, ADTRAN recommends that the outdoor

connector on the coaxial cable be weatherproofed to prevent corrosion and electrical shorting.

In areas where lightning strikes are frequent, a lightning arrestor should be installed

directly on the antenna coaxial cable. Installing lightning arrestors helps protect the

RF electronics (including the TRACER 6420 unit) in the downstream path from

damaging voltages and currents.

Section 2 Microwave Path Engineering Basics TRACER 6420 System Manual

Table 2 gives typical loss figures for some of the more common coaxial cable types (per 100 feet).

Path Loss (LP)

Path loss is the estimated attenuation between the transmit and receive antennas caused by signal

separation and scattering. The path loss is considered basic transmission loss over the microwave link. The

following expression calculates path loss:

where

fcarrier frequency (Hz)

λcarrier wavelength (c / f) (meters)

dpath distance (meters)

cspeed of light, free-space (meters)

where d is expressed in miles and f in GHz

Path loss, as shown here, increases rapidly as either the path length increases or the carrier wavelength

decreases (which happens as the carrier frequency increases). Therefore, longer microwave paths naturally

experience more path loss than shorter paths. Likewise, higher frequency microwave communication

experiences more path loss than lower frequency microwave communication.

listed in the table can be interpolated from those listed.

5. RECEIVER SENSITIVITY

Receiver sensitivity is a value expressed in decibels referenced to one milliwatt (dBm) that corresponds to

the minimum amount of signal power needed at the receiver to achieve a given bit error rate (BER).

Receiver sensitivity is usually a negative number of decibels, and smaller receiver sensitivity (higher

quantity negative number) is better for a given BER. Several factors affect receiver sensitivity, including

the data bandwidth of the wireless link and the amount of additional signal degradation introduced in the

receiver electronics.

Receiver sensitivity of the TRACER 6420 is dynamic as a function of the desired bandwidth; receiver

sensitivity improves as delivered bandwidth decreases. TRACER bandwidth is provided in the form of 8

channels available for mapping to the support modules. For T1 Modules, each channel mapped represents

a single T1 interface. For Quad Ethernet Switch Modules, each channel mapped represents 2 Mb of switch

data delivered to the module. In situations where 8-channel connectivity is not required, the delivered

bandwidth can be decreased to 4 or 2 channels, and the receiver sensitivity will be improved as follows:

Should an interferer be present nearby, three software selectable band plans are provided

for frequency agility. Changing the TRACER 6420 band plan does not require additional

components, or opening of the radio. See > RF Link Configuration > RF Band Plan on

page 53 for additional details.

Section 2 Microwave Path Engineering Basics TRACER 6420 System Manual

6. ANTENNA INFORMATION

The overall wireless system is directly affected by the antenna selection and installation, discussed in the

following sections.

Antenna Alignment

With line-of-sight microwave communications, optimum system performance requires that the

transmitting and receiving antennas are properly aligned. This ensures maximum received signal power at

each receiver. Antenna alignment must be achieved in both azimuth (along a horizontal plane) and

elevation (along a vertical plane). By ensuring maximum received signal strength, a received signal

strength indicator (RSSI) helps the equipment installer to determine when alignment is maximized.

TRACER RSSI Test Points

RSSI for the TRACER 6420 system is provided through the VT100 terminal menus accessed through the

RS-232 interface, and it is presented as a series of bars indicating signal strength. More bars means more

RSSI, which ensures greater received signal strength and better link performance.

If both the local and remote end of the system are operational, the remote TRACER 6420 receive power

can be viewed from the local TRACER 6420 VT100 terminal menu interface.

An RSSI test point, located on the front panel, provides a DC voltage level (relative to the GND test point)

that corresponds to the amount of signal being received from the far end's transmitter. The voltage at this

test point can vary from approximately 0 to 5 VDC. An RSSI calibration sheet is shipped with the system

to provide the installer a cross-reference between actual received signal level (in dBm) and RSSI voltage.

This sheet is useful for verifying link budget calculations and ensuring proper equipment installation.

Antenna Beam Patterns

Directly related to the subject of antenna alignment is the topic of antenna beam patterns. Antennas used

with the TRACER 6420 system have a particular beam shape, determined in part by the physical

construction and geometry of the antenna. The antenna beam patterns are characterized by a dominant

main lobe, which is the preferred lobe to use for point-to-point communications, and several side lobes, as

shown in Figure 2. When setting up a microwave link, antenna alignment is nothing more than steering the

main lobes of both antennas until the main lobe of one transmitter is centered on the receiving element of

the receiving antenna.

Verify the antenna installation meets all regulations specified in the National Electric

Code (NEC) Article 810.

TRACER 6420 System Manual Section 2 Microwave Path Engineering Basics

Figure 2. Typical Antenna Beam Pattern

Antennas are also designed to radiate RF energy efficiently for a specific range of frequencies. Please

consult the data sheet for your particular antenna make and model to ensure that it is specified to operate in

the 5725 MHz to 5850 MHz frequency band for the TRACER 6420 system.

Fresnel Zones, Earth Curvature, and Antenna Heights

Fresnel zones correspond to regions in the microwave path where reflections of the intended signal occur

and combine in both constructive and destructive manners with the main signal, thereby either enhancing

or reducing the net power at the receiver.

In general, the odd numbered Fresnel zones (1, 3, 5, ...) add constructively at the receiver, while the even

numbered Fresnel zones (2, 4, 6, ...) add destructively at the receiver.

The first Fresnel zone corresponds to the main lobe, 60% of which must be free of physical obstructions

for the path calculations to be valid. Since the main lobe contains the vast majority of the microwave

energy, this zone is typically used to determine proper antenna heights when placing antennas on towers or

buildings.

The curvature of the Earth becomes a legitimate obstruction for path lengths of 7 miles or greater, and must

also be accounted for when determining minimum antenna heights.

The aggregate expression for minimum antenna height that incorporates both the 60% first Fresnel zone

and the Earth’s curvature is given by

where f is in GHz and d is in miles.

7. OTHER CONSIDERATIONS

Path Availability

The path availability of a wireless link is a metric that expresses the fractional amount of time a link is

available over some fixed amount of time, and depends on several factors. Path availability is expressed as

where the parameters are

aterrain factor

bclimate factor

fcarrier frequency (GHz)

dpath length (miles)

Ffade margin (dB)

Terrain Factor (a)

The terrain factor is a quantity that compensates the link availability for different types of terrain.

Generally speaking, the smoother an area's terrain is, the less availability a wireless link running over that

terrain will have, primarily due to multipath reflections. In contrast, secondary microwave signals will be

randomly dispersed over rough terrain and will not interfere with the main signal lobe as badly as in the

smooth terrain case. The terrain factor values normally used are listed below:

Climate Factor (b)

The climate factor is a quantity that compensates the link availability for different types of climates

(weather). In general, microwave links operating in areas with high humidity will have less availability

than those in arid areas, primarily because water is a dispersive mechanism to microwave energy and

causes the main signal lobe to refract and disperse away from the receiver location. The climate factor

values normally used are listed below:

Terrain Terrain Factor Description

Smooth 4water, flat desert

Average 1moderate roughness

Mountainous 1/4 very rough, mountainous

Climate Climate Factor Description

Very Dry 1/8 desert regions

Temperate 1/4 mainland, interior region

Humid 1/2 humid and coastal regions

DC Power Connection (Plug-In Terminal Block)

The TRACER 6420 can operate from a supply between 21 and 60 VDC, with either polarity referenced to

ground, and consumes less than 25 W. Power supplies should be able to provide up to 25 W at the selected

voltage. Current required (in Amps) is determined by dividing the power consumed (in Watts) by the

applied voltage (in Volts). For example, at 48 V, TRACER 6420 would draw approximately 0.52A

(25 W/48 V).

Fuse

The fuse holder, accessible from the rear panel of the TRACER 6420, accepts a generic 2 A, 250 V, 2-inch

slow-blo fuse.

Alarm Contacts (Plug-In Terminal Block)

An RF link down condition is indicated with both normally open (NO) and normally closed (NC) alarm

contacts on the rear panel of the TRACER 6420 system. In normal operation, the NC contact is electrically

connected to the common contact (COM) and the NO contact is isolated. When the RF link drops, the NC

contact becomes isolated and the NO is electrically connected to COM. This allows RF down conditions to

be reported to external alarm monitoring systems. Table 9 provides the Alarm Contact pinout.

Antenna Interface (N-Type connector)

The ANTENNA interface (N-Type connector) connects to the customer-supplied antenna using standard

antenna feedline cable. When determining the cable specifications for your application, refer to Section 2,

4. CHANNEL SELECTION

The FCC has allocated 125 MHz of spectrum in the 5.8 GHz band where the TRACER 6420 operates.

Figure 1 illustrates the bandwidth division.

Figure 1. 5.8 GHz Bandwidth Division

To designate the utilization of the ISM bandwidth, there are two different channel plans, labeled A and B.

The letter of each channel plan setting is preset by the factory and refers to the physical configuration of

the diplexer filter inside the chassis. Each channel is then divided into three band plans (1, 2 or 3). The

band plans must be the same for the local and remote TRACER 6420. For example, the transmitter at one

end of the link will transmit in band plan 1 of channel A (the lower portion of the spectrum) and receive in

band plan 1 of channel B (the upper portion). Consequently, the receiver at the other end should receive in

band plan 1 of channel A (the lower portion) and transmit in band plan 1 of channel B (the upper portion).

The letter of the channel plan (A or B) must be different on both ends and the number of the band plan (1,

2, or 3) must be the same on both ends. The default band plan configuration for the TRACER 6420 is band

plan 1.

The channel plan (A or B) of the unit may be changed in the field, if necessary, by rewiring the internal

diplexer. Contact Technical Support for more information on this procedure.

5. GROUNDING INSTRUCTIONS

The following paragraphs provide grounding instruction information from the Underwriters’ Laboratory

UL60950 Standard for Safety of Information Technology Equipment Including Electrical Business

Equipment, with revisions dated March 15, 2002.

An equipment grounding conductor that is not smaller in size than the ungrounded branch-circuit supply

conductors is to be installed as part of the circuit that supplies the product or system. Bare, covered, or

insulated grounding conductors are acceptable. Individually covered or insulated equipment grounding

conductors shall have a continuous outer finish that is either green, or green with one or more yellow

stripes. The equipment grounding conductor is to be connected to ground at the service equipment.

The attachment-plug receptacles in the vicinity of the product or system are all to be of a grounding type,

and the equipment grounding conductors serving these receptacles are to be connected to earth ground at

the service equipment.

A supplementary equipment grounding conductor shall be installed between the product or system and

ground that is in addition to the equipment grounding conductor in the power supply cord.

The supplementary equipment grounding conductor shall not be smaller in size than the ungrounded

branch-circuit supply conductors. The supplementary equipment grounding conductor shall be connected

to the product at the terminal provided, and shall be connected to ground in a manner that will retain the

ground connection when the product is unplugged from the receptacle. The connection to ground of the

supplementary equipment grounding conductor shall be in compliance with the rules for terminating

bonding jumpers at Part K or Article 250 of the National Electrical Code, ANSI/NFPA 70. Termination of

the supplementary equipment grounding conductor is permitted to be made to building steel, to a metal

electrical raceway system, or to any grounded item that is permanently and reliably connected to the

electrical service equipment ground.

The supplemental grounding conductor shall be connected to the equipment using a number 8 ring terminal

and should be fastened to the grounding lug provided on the rear panel of the equipment. The ring terminal

should be installed using the appropriate crimping tool (AMP P/N 59250 T-EAD Crimping Tool or

6. SUPPLYING POWER TO THE UNIT

The TRACER 6420 can operate from a supply between 21 and 60 VDC, with either polarity referenced to

ground. Power supplies should be able to provide up to 25 Watts at the selected voltage. A dual pin terminal

plug accepts power at the rear panel of the unit, providing a voltage (+/–) and ground (GND) reference point.

7. MOUNTING OPTIONS

Install the TRACER 6420 in a location that requires minimal antenna feedline length (the loss in this cable

directly affects overall system performance). The TRACER 6420 is designed to be mounted in a rack. If

multiple units are installed in one location, one half inch of spacing is recommended above and below the

unit.

The TRACER 6420 systems are 1U high, rack-mountable units which can be installed into 19- (see Figure 2)

or 23-inch (see Figure 3 on page 40) equipment racks using the supplied rackmount brackets (3265498@B).

system, you should have one A and one B frequency plan.

G. Rx Quality

Displays an indicator of receive signal quality that is not necessarily related to receive signal level (for

both the local and remote units) using a series of symbols (#). The more symbols displayed, the better

the signal quality. This indicator is related to signal-to-noise ratio and features a colon (:) marker to

indicate 10-6 bit error rate. This indicator is useful as a diagnostic tool to help identify interference, as

the system may have high receive signal level and poor signal quality in situations where interference

is an issue.

H. Rx Power

Displays the approximate receiver levels (for both the local and remote units) using a series of symbols

(#). The more symbols (#) displayed, the stronger the signal. If the link is down in either direction and

remote end data is unavailable, DATA NOT AVAILABLE is displayed in place of the symbols (#).

I. Tx Power

the remote site.

TRACER 6420 System Manual Section 5 User Interface Guide

> RF LINK CONFIGURATION > RF BAND PLAN

Sets the band plan for the TRACER 6420. Each channel is divided into three band plans (1, 2, or 3). Both

local and remote TRACER 6420 must be configured with the same band plan (1, 2, or 3) but different

channel plans (Plan A or Plan B). For example, the transmitter at one end of the link will transmit in band

plan 1 of channel A (the lower portion of the spectrum) and receive in band plan 1 of channel B (the upper

portion). Consequently, the receiver at the other end should receive in band plan 1 of channel A (the lower

portion) and transmit in band plan 1 of channel B (the upper portion). (Refer to Figure 6 for the division.)

The TRACER 6420 comes factory programmed with RF band plan set to Band 1.

Figure 6. 5.8 GHz Bandwidth Division

> RF LINK CONFIGURATION > LINK ENCRYPTION

The TRACER 6420 provides Triple-DES (3DES) encryption of the data passed over the RF Link. When

LINK ENCRYPTION is set to ENABLED, the TRACER 6420 sequentially applies the three keys entered in the

SUBKEY 0, 1, and 2 fields to each 64-bit block of data transmitted over the RF link. The remote TRACER

6420 uses the same keys to decrypt each block. (The keys entered in the local and remote systems must be

identical.)

> RF LINK CONFIGURATION > SUBKEY (0-2)

The TRACER 6420 provides 3DES encryption of the data passed over the RF Link. When LINK

ENCRYPTION is set to ENABLED, the TRACER 6420 sequentially applies the three keys entered in the

SUBKEY 0, 1, and 2 fields to each 64-bit block of data transmitted over the RF link. The remote

TRACER 6420 uses the same keys to decrypt each block. (The keys entered in the local and remote

systems must be identical.) Valid entries are numbers 0 through 9 and letters a through f.

When changing RF band plans on installed links, change the remote end first. If the local

end is changed first, remote configuration capability is lost. In the event the local end is

changed first and the link is dropped, reset the local end to the previous setting to restore

the link.

DLP-4 Verifying Communications Over an IP LAN

Introduction

When the 10/100BaseT MGMT port is connected to a local area network (LAN), test steps must be

performed on the TRACER 6420 to ensure that the unit is communicating properly over the network. This

procedure outlines those steps.

Prerequisite Procedures

Before beginning this procedure, the unit should be physically connected to the LAN and the provisioning

tasks detailed in DLP-3, Setting IP Parameters for the TRACER 6420, should be complete.

Tools and Materials Required

• Access to a PC or other computer connected to the LAN

To prevent electrical shock, do not install equipment in a wet location or during a

lightning storm.

Electronic equipment can be damaged by static electrical discharge. Before handling it,

put on an antistatic discharge wrist strap to prevent damage to electronic components.

Place equipment in antistatic packing material when transporting or storing. When

working on equipment, always place it on an approved antistatic mat that is electrically

grounded.

Section 6 DLP-4 TRACER 6420 System Manual

82 612806420L1-1A

1. Verify the TRACER 6420 IP address.

If you do not already have the IP Address for the TRACER 6420, obtain it from the network

administrator or manually check for the address on the MANAGEMENT/SNMP CONFIGURATION page.

(Access the MANAGEMENT/SNMP CONFIGURATION page by pressing 7 and then 1 from the Main menu

page.)

2. Ping the TRACER 6420 unit from a remote computer on the network.

Using a remote computer system connected to the LAN, perform an ICMP Ping on the IP Address of

the TRACER 6420. Verify that the unit responds properly. If the TRACER 6420 fails to respond, try

the following:

• Verify that the proper IP Address, Subnet Mask, and Default Gateway are provisioned in the unit

(see DLP-3, Setting IP Parameters for the TRACER 6420, for details).

• Verify that the TRACER 6420 is properly cabled into the LAN and that the Ethernet cable is

properly seated in the RJ-45 jack on the rear of the unit.

• If the TRACER 6420 is connected to a hub or other network device that provides a carrier sense

light for each port, verify that the carrier sense light for the port to which the TRACER 6420 is

connected is lit. If this light is not lit, check the cabling between the hub and the shelf. The

connection may also be verified using the activity LED located on the rear of the unit (part of the

10/100BaseT MGMT RJ-45 connector).

• Verify the IP Address, Subnet Mask, and Default Gateway on the remote computer system.

• If none of these steps are successful, contact the LAN Administrator for assistance.

Perform the following steps in the order listed.

Refer to the computer system’s documentation if you are unsure how to perform a Ping

command. Most computers running a networked version of Microsoft Windows™ or UNIX

allow a Ping to be performed by typing ping <IP Address> at a command line prompt.

Typically, the Ping program will respond by indicating that the remote IP Address has

responded in a certain amount of time or that no response was received.

Some versions of Ping will continue running until you explicitly tell them to stop. If the

program does not terminate on its own, type <CTRL+C> to stop the program.

TRACER 6420 System Manual Section 6 DLP-4

612806420L1-1A 83

3. Telnet to the TRACER 6420.

Telnet session is properly opened. Once the Telnet session is established, press <CTRL+Z> to logout

of the session and return to the Login screen. Pressing <CTRL + Z> again closes the Telnet session.

Refer to the documentation of the computer system if you are unsure how to initiate a

Telnet session. Most computers running a networked version of Microsoft Windows™ or

UNIX initiate a Telnet session by typing telnet <IP Address> at a command line prompt.

The Windows XP HyperTerminal program also provides a Telnet client. Telnet is a utility

common on many local area networks that allows remote access to another computer or

piece of equipment.

information to the remote system over the service channel. Service

channel communications over the RF link allow a user connected to a

local system to upgrade the firmware of a remote system. Before the

remote system begins the firmware upgrade process, a complete copy

of the new firmware image must be received and stored in the remote

system. This is done automatically when the remote system is chosen

from the UPGRADE DESTINATION field.

SENDING SC TRANSFER Indicates that the local system is sending the firmware upgrade

information to the remote system over the service channel. Service

channel communications over the RF link allow a user connected to a

local system to upgrade the firmware of a remote system. Before the

remote system begins the firmware upgrade process, a complete copy

of the new firmware image must be received and stored in the remote

system. This is done automatically when the remote system is chosen

from the UPGRADE DESTINATION field.

VERIFYING FLASH IMAGE Indicates that the system flash image is being verified as a valid image

for the specified update. Before the new firmware is loaded into the local

flash, the TRACER 6420 verifies that the flash image is valid for the new

firmware. If it is not valid for the system, the firmware upgrade fails.

ERASING FLASH Indicates that the system flash is being erased so the new firmware

image can be loaded into the local flash. Before the new firmware is

loaded into the local flash, the TRACER 6420 verifies that the flash

image is valid for the new firmware. If it is not valid for the system, the

firmware upgrade fails.

PROGRAMMING FLASH Indicates that the new firmware image is being loaded into the local

flash. Before the new firmware is loaded into the local flash, the

TRACER 6420 verifies that the flash image is valid for the new firmware.

If it is not valid for the system, the firmware upgrade fails.

DLP-6 Updating the Firmware Using XMODEM

Introduction

The TRACER 6420 supports firmware updates of the local and remote systems using TFTP or XMODEM.

Use the 10/100BaseT MGMT port and TFTP from a network server or XMODEM (if your Telnet client

supports file transfers), or use XMODEM and the CRAFT interface. This procedure outlines the steps for a

successful firmware upgrade using the CRAFT interface and XMODEM software. The same XMODEM

steps apply for file transfers through your Telnet client (refer to your Telnet client documentation for more

details on file transfer specifics). (See DLP-5, Updating the Firmware Using TFTP, for instructions on

using TFTP.)

Tools and Materials Required

• VT100 terminal or PC with VT100 terminal emulation software

• XMODEM software

To prevent electrical shock, do not install equipment in a wet location or during a

lightning storm

Electronic equipment can be damaged by static electrical discharge. Before handling it,

put on an antistatic discharge wrist strap to prevent damage to electronic components.

Place equipment in antistatic packing material when transporting or storing. When

working on equipment, always place it on an approved antistatic mat that is electrically

grounded.

Section 6 DLP-6 TRACER 6420 System Manual

1. Connect to the TRACER 6420 using the front panel DB-9 CRAFT interface.

If you are not already connected to the unit’s CRAFT interface (either with a VT100 compatible

terminal or with a PC running VT100 emulation software), follow the procedure in DLP-1, Connecting

a VT100 Terminal or PC to the CRAFT Port. Connecting to the CRAFT interface limits the upgrade

procedure to XMODEM only.

2. Log in to the unit (see DLP-2, Logging in to the TRACER 6420 for details).

errors encountered during the download.

9. Select START from the COMMAND menu to start the update.

When the TRACER 6420 is ready to receive the XMODEM upload, the menu screen will clear and

display XMODEM waiting for start....<Ctrl-X> twice to Cancel. If this does not appear, please

review the steps above for possible configuration errors.

10. From the terminal emulation software, begin the XMODEM upload by using the appropriate command

sequence. This may take several minutes.

If necessary, refer to the terminal emulation software documentation for help. Also, when specifying

the filename, ensure that the file transferred is the one provided by ADTRAN. Otherwise, the update

will not complete successfully.

Because XMODEM data is being transferred inband through the menu interface, the VT100 menus of

the TRACER 6420 will be inoperable from the CRAFT interface. You can cancel the update at any

time within the terminal emulation software. (Please consult the documentation provided by the

terminal emulation software to determine how to do this).

11. When the update has successfully completed, IDLE displays in the CURRENT UPDATE STATUS field and

UPGRADE FINISHED SUCCESSFULLY displays in the PREVIOUS UPDATE STATUS field.

The TRACER 6420 will restart immediately and resume operation. During reset and initialization, the

RF link between the units will not be operational.

Alternatively, if the unit is part of a management cluster connected to the local network, you may use a

PC connected to the network to Telnet into the unit. By using the 10/100BaseT MGMT port, the

TRACER 6420 may be quickly upgraded using TFTP, provided there is a TFTP server on the local

Section 8 Troubleshooting Guide TRACER 6420 System Manual

1. OVERVIEW

This troubleshooting guide provides recommended actions for various conditions of the TRACER 6420

system. The status LEDs (located on the front panel of the unit) provide information to help determine the

necessary troubleshooting action. This guide contains recommended actions for resolving possible

problems indicated by the status LEDs.

2. LED INDICATORS

PWR LED

If the PWR LED is not ON and solid green, the TRACER 6420 is not receiving adequate DC power.

Recommended Actions:

1. Verify that the power source is delivering between 21 and 60 VDC.

2. Check the polarity of the power connection (referenced to ground) of both the TRACER 6420 unit and

the power source.

3. Check the internal fuse. The fuse is accessed from the rear panel of the unit. If this fuse is open,

replace with a 2 A, 250 V (2-inch) slow-blo fuse.

TST LED

The TST LED will flash once (amber) during power-up to indicate a self-test is in progress. If the TST

LED is flashing or remains ON after 10 seconds, the TRACER 6420 unit has failed the self-test. This is an

internal failure, and technical support should be contacted.

RF DWN LED

If the RF DWN LED is ON (solid red), there is a problem with the RF receive path from the remote

TRACER 6420.

Recommended Actions:

1. Verify that one end of the link is configured as Plan A and the other end as Plan B.

2. Measure the RSSI voltage and consult the RSSI calibration sheet included with the unit. If the voltage

level corresponds to a received signal power level that agrees with the calculated receive signal level,

proceed with Step 7.

3. Check the RF coaxial cable connection.

4. Verify that the antenna polarization is the same at both ends of the RF signal transmit and receive

path.

5. Verify the RF signal path is clear.

6. Check the integrity of the lightning arrestors.

7. Check for possible interference at both ends of the link. If necessary, change polarization and/or band

plans at both ends.

TRACER 6420 System Manual Section 8 Troubleshooting Guide

RF LOW LED

If the RF LOW LED is ON (solid red), the received signal is approaching 0 V of RSSI. This condition is

typically indicative of a path or installation problem.

Recommended Actions:

1. Verify the far-end transmitter power setting is the value that the link planning budget allows.

2. Check all coaxial cable connectors for solid connections. Check for water and corrosion around any of

the connectors. If water is apparent in the coaxial connectors, replace the coaxial cable and the

connectors, making sure to properly weatherproof the replacements.

3. Verify the RF signal path by verifying the antenna alignment.

4. Check the integrity of lightning arrestors.

T1 Interface Alarm LEDs

If the ALARM LED is ON (solid red), it is an indication that the TRACER 6420 is detecting an active T1

alarm. To identify the T1 interface in alarm and the specific alarm present, display the T1(X) STATUS screens

and check the T1(X) INTERFACE ALARMS field.

Recommended Actions:

1. Display the T1(X) STATUS screen and check the T1(X) INTERFACE ALARM field to identify the active alarm.

2. Follow the steps below for the appropriate alarm.

LOS Alarm (Red Alarm)

LOS ALARM is an indication that the TRACER 6420 may be unable to detect a viable T1 received signal

from the connected T1 equipment. This error may be due to a degraded signal or no signal, or may be

caused by improper framing.

Recommended Actions:

1. Verify that the T1 cable is connected to the T1 interface on the TRACER 6420.

2. Verify the connections at the opposite end of the T1 cable.

3. Verify that the framing mode (D4 or ESF) is the same for both the TRACER 6420 and the T1

equipment.

Yellow Alarm

A Yellow Alarm is generated by the attached equipment. When the attached equipment’s T1 interface is

in Red Alarm, the TRACER 6420 generates a Yellow Alarm.

Recommended Actions:

1. Follow the troubleshooting steps for Red Alarm, but do so at the attached equipment.

Blue Alarm

A remote alarm (alarm indication signal or AIS) is generated by the attached equipment. The root cause

must be determined at the attached equipment. A typical cause of a blue alarm is a lack of input to a

CSU.

Recommended Actions:

1. Verify the input to any attached data equipment.

Section 8 Troubleshooting Guide TRACER 6420 System Manual

BPV

Bipolar violations (BPVs) indicate an improper configuration or faulty wiring.

Recommended Actions:

1. Verify the TRACER 6420 unit and the attached equipment are configured for the same line coding

(B8ZS or AMI).

2. Verify the cable connections for the T1 interface are solid.

LAN LEDs

If the LAN LED is OFF, the TRACER 6420 is not able to detect an active Ethernet link on the particular

10/100BaseT/TX interface.

Recommended Actions:

1. Check all Ethernet cable connections to verify they are properly plugged in (making sure the tab on the

connector snaps into place).

2. Connect the 10/100BaseT/TX interface to a “known good” Ethernet port to verify the TRACER port is

functioning properly.

3. Try another Ethernet cable.

3. RF ERRORS

RF errors can range from a nonviable microwave path to loose RF connectors.

Nonviable path conditions could be caused by physical obstructions such as buildings, mountainous

terrain, trees, etc., as well as other physical limitations such as excessive path distances and in-band RF

interference. These types of errors are remedied by performing a detailed line-of-site microwave path

study to determine whether a microwave link is feasible for the terrain and environment under

consideration.

If after performing a microwave path study the system is still not operational, ensure that the antennas are

properly aligned. Note that alignment must be achieved in both elevation and azimuth for optimal link

performance. The TRACER 6420 can be used to aid in antenna alignment by looking at the RX POWER

“fuel gauge” on the System Status or System Option menu pages or by measuring the DC voltage (relative

to ground) at the RSSI front panel test jack. Optimal antenna alignment is achieved by peaking the front

panel RSSI voltage or the RX POWER “fuel gauge” on the TRACER 6420 terminal display. Consult the

ADTRAN TRACER Data Sheet included with the unit to verify that the actual receive signal level agrees

with the calculated receive signal.

An RSSI test point, located on the front panel, provides a DC voltage level (relative to the GND test point)

that corresponds to the amount of signal being received from the far end's transmitter. The voltage at this

test point can vary from approximately 0 to 5 VDC. An RSSI calibration sheet is shipped with the system

to provide the installer a cross-reference between actual received signal level (in dBm) and RSSI voltage.

This sheet is useful for verifying link budget calculations and ensuring proper equipment installation.

4. STEP-BY-STEP TROUBLESHOOTING

The logical troubleshooting flow presented in this section can be used to set up your TRACER 6420

system, and also to diagnose a previously installed system. Please contact Technical Support at any stage

during installation and/or troubleshooting if you require assistance.

TRACER 6420 System Manual Section 8 Troubleshooting Guide

5. INSTALLING/TROUBLESHOOTING THE TRACER HARDWARE

1. Perform a detailed path profile and link budget for each TRACER 6420 microwave link. A thorough

path study can be used to estimate signal power budgets, estimate fade margins at each receiver,

identify potential line-of-site obstacles, properly size antenna dishes, and determine minimum

antenna dish heights above the earth.

2. Set up all of the TRACER 6420 hardware on a workbench. The actual cables used in the permanent

installation should be used in the workbench setup. A rigorous workbench “simulation” of the link

will help alleviate and avoid time-consuming errors.

3. Examine the PLAN A and PLAN B LEDs on the front panel of each unit. These LEDs indicate the

frequency plan for each TRACER 6420 unit. Each TRACER link must have a Plan A radio on one

side and a Plan B radio on the other.

4. Attach the RF coaxial cables to be used in the permanent installation to the N-type connectors on the

back of the TRACER 6420 unit. Attach the other end of the coaxial cable(s) to an RF power meter or

spectrum analyzer, if either is available. The power measured by the meter/analyzer will be the RF

power available at the input of the antenna. The TRACER 6420 unit is programmed at the factory to

output approximately 100 mW (20 dBm) of RF power. The actual power level measured by the

meter/analyzer will be less than 100 mW due to RF losses through the coaxial cable, and is a function

of the cable type and length being used. In any event, the power level at the output of the coaxial cable

should be a significant fraction of 100 mW. A power meter/analyzer reading that is not on the order of

at least tens-of-milliwatts could be an indication of unsuitable RF cable or faulty or unreasonably long

coaxial cable, or a combination of these factors.

5. Resolve all RF coaxial cabling errors before proceeding.

6. Attach the RF coaxial cables to a high-quality attenuator, if possible. If you do not have an attenuator,

attach the coaxial cables to the antennas to be used in the permanent installation. If the installation

antennas are not available, small, inexpensive dipole or patch antennas can be used for verification

purposes. If an adjustable attenuator is being used, dial in the amount of attenuation that corresponds

to the path loss value expected for the microwave link in which the TRACER hardware will be

installed. The path loss value can be calculated from a knowledge of the path length, or provided by a

path study. Remember to subtract both antenna gain values from the attenuator level if these values

have not already been accounted for.

7. After setting up the RF pieces, examine the RF DOWN LED on the front panel of each

TRACER 6420 unit. If the RF DOWN LED is illuminated (red), the corresponding TRACER 6420 is

not receiving a suitable RF signal from the other TRACER 6420 unit. In this case, the receiving

TRACER 6420 is either receiving a very weak signal or no signal at all. If the RF DOWN LED is not

illuminated, then the TRACER 6420 units are receiving a suitable RF signal. Suitable RF power

levels for low error rate communication will range from -30 dBm to -88 dBm measured at the N-type

connector input on the TRACER 6420 unit.

8. Resolve any signal level issues before proceeding.

9. Examine the RF LOW LED on the front panel of each TRACER 6420. If this LED is illuminated, then

the TRACER 6420 is receiving a relatively weak signal; however, if the RF DOWN LED is not

illuminated, then the received signal is being suitably processed by the TRACER 6420 system. If you

are receiving a weak signal (RF LOW is ON), please verify that the weak signal is not being caused by

a faulty cable, an insufficiently tightened cable, or some other installation-related problem. Also,

make sure an unreasonably large attenuation value has not been selected if you are using an attenuator

on a workbench setup.

Section 8 Troubleshooting Guide TRACER 6420 System Manual

Use the tables in Section 2, Microwave Path Engineering Basics, of this manual to select the

proper free-space attenuation value (in dB) based on the estimated length of the microwave path.

Remember to subtract both antenna gains (local and remote) from the attenuator setting.

10. Test the installed modules by performing the following:

11. Command a link loopback on the remote TRACER 6420 unit and run a test pattern from the

connected T1 equipment. This will verify the data path across the RF link.

Installing/Configuring T1 Hardware

1. If possible, attach any or all of the intended T1 hardware to the TRACER 6420 units using the

same workbench setup. This step offers the perfect opportunity to configure your T1 hardware for

proper functioning with the TRACER 6420 hardware.

2. To significantly reduce the probability of an unsuccessful field installation, resolve any remaining

T1 equipment-to-TRACER 6420 configuration issues before field installation. See T1 Interface

Alarm LEDs on page 105 for more information on resolving T1 interface alarm conditions.

Installing/Configuring Ethernet Hardware

1. If possible, attach any or all of the intended Ethernet hardware to the TRACER 6420 units using

the same workbench setup. This step offers the perfect opportunity to configure your Ethernet

hardware for proper functioning with the TRACER hardware.

2. To significantly reduce the probability of an unsuccessful field installation, resolve any remaining

Ethernet equipment-to-TRACER 6420 configuration issues before field installation.

4xT1 Module

Initiate a line loopback on the local TRACER 6420 unit and run a test pattern from the connected

T1 equipment. This will verify the connection between the T1 equipment and the local

TRACER 6420 unit.

Quad Ethernet Switch Module

Connect a computer (or Ethernet test equipment) to the TRACER 6420 Ethernet interfaces.

Perform a “ping” from one test station across the wireless link to another test station connected to

the remote TRACER 6420. This will verify the data path between the test equipment and the

TRACER 6420 unit.

External pattern generators are required to test data path integrity. An T1 BERT tester is

suggested.
