Chapter 1 Overview
The ATLAS4900 is a point-to-point (PtP) wireless Ethernet transmission system which provides network connectivity at
speeds up to 45 Mbps depending on the transmission distance and noise floor. The Atlas4900 utilizes OFDM technology
and is designed for use in long range backhaul and wide area data networking applications. The Atlas system is
comprised of the following items:
1) P4900M-INT18, -INT22 or -EXT (user-configured as Master Unit)
2) P4900M-INT18, -INT22 or -EXT (user-configured as Remote Unit)
3) Two 24 Volt power adapters for use with 100 to 240 VAC, including various plug adapters
4) Two Power over Ethernet Junction Boxes
5) Two Port plug covers
6) Mounting hardware
The Atlas4900 system consists of two P4900M radio units and uses a common hardware/firmware platform for
each end of the wireless link. Users are required to simply specify one unit type as master unit (MU) and one unit
as remote unit (RU). The hardware consists of a high gain dual polarized panel antenna with the radio portion
integrated into a cast aluminum case on the back of the antenna, or an external dish antenna. The unit utilizes
Power-over-Ethernet (PoE) and is designed for outdoor environments. The cable entry point can accommodate both
Shielded twisted pair Cat5 (STP), Unshielded twisted pair Cat5 (UTP), with the addition of conduit for tower
mounting.

Chapter 2 Getting Started
It is recommended that you first provision and test your the radios on the bench before deploying them in the field. This is a
particularly useful exercise for the novice user.
Connections and Power
• Connect a Cat-5 (straight through) Ethernet cable (we recommend shielded twisted pair) between the ODU (out door
unit) port of the J-box and the RJ-45 connector on the radio. Note that this cable will carry power-over-Ethernet
(PoE).
• If connecting to a COMPUTER, use a Cross-Over Ethernet cable from the NET port of the J-box to the computer’s
Ethernet port.
If connecting to a HUB, SWITCH, or ROUTER, use a Straight-Thru cable.
• Plug the AC adapter into an AC outlet.

Both green LEDs on the J-box should be lit, indicating power is present at the Power-over-Ethernet box as well as at the radio.
You are now ready to configure the radio via the Ethernet port. The Radio Power LED may take several seconds before
lighting. The radio requires approximately 45 seconds to boot.
Configuration Tools
ATLAS4900 radios can be configured using either the Command Line Interface (CLI), or the Web Browser (HTTP) interface.
Although both methods are comprehensive and powerful, the CLI method provides slightly more functionality.
Getting Started
Trango Broadband Wireless — ATLAS4900 page 6
This text covers configuration through the CLI. For HTTP configuration please see Appendix A.
Telnet
Open a command prompt (DOS) session on your PC. Open a Telnet session by typing:
telnet <ip address of radio>
Example:
C:>telnet 192.168.100.100
Note: All Trango radios are pre-configured at the factory with a default IP address of 192.168.100.100.
You will be greeted with current hardware and firmware information and prompted for a password. Type in the password and
press enter. The factory default read/write password is trango.

Chapter 3 Configuration
Key Concepts
Prior to configuring the radios it is important to understand several key concepts:
Master Unit (MU) The MU is typically considered the primary radio within the link. For management purposes
it is recommended to install the MU closest to the head-end of the network.
Remote Unit (RU) The RU is typically installed at the remote end of the link. The primary distinction between
the MU and RU is that when the radios are not associated, the MU will transmit and the RU
will listen until the wireless link is established.
Peer ID Authentication is controlled by the MAC address of each radio. The Peer ID is defined as the
MAC address of the opposite radio. In other words, the Peer ID of the MU is the RU’s MAC
address and the Peer ID of the RU is the MU’s MAC address.
Opmode Operation mode (on or off). The radio will only transmit while set to Opmode ON.
Default Opmode Opmode (on or off) which the radio enters after reboot. Note: if you telnet into a radio
within 30 seconds after reboot, the radio will remain in opmode OFF even if the default
opmode is ON.
Essentials to Establish a Wireless Link
Configuration of the Atlas system is simple and at a minimum requires the following settings:
1. Designate one radio as the Master Unit (MU) and one unit as the Remote Unit (RU).
2. Program Peer ID in each radio.
3. Set MU and RU to same channel and antenna polarization
4. Set default Opmode to “ON” so that radio will automatically enter opmode after reboot.
5. Turn radios Opmode “ON”.
If all of these parameters are met, and if the MU and RU are within range and properly aligned, the wireless link will
automatically establish itself and Ethernet traffic will begin to pass between the radios.
Master Unit Configuration
Start a telnet session with one of the radios. Follow these steps for configuration.
1. Set the Unit Type (utype) to MU in one radio. (default for all radios is RU)
#> utype mu
Success.
#>
2. Set the Peer ID with the MAC address of the RU. Only use the last 8 digits of the MAC address.
#> peerid de1B7850
Success.
#>
3. Set channel and polarization. (in this example set the channel to 1 and polarization to H).
#> freq 1 h
Configuration
Trango Broadband Wireless — ATLAS4900 page 10
Ch# 1 h (4950 MHz)
Success.
4. Set default Opmode to ON.
#> defaultopmode on
Success.
5. Turn Opmode ON.
#> opmode on
Success.
.
Remote Unit Configuration
Configure the RU in the same manner as the MU. Since the default unit type (utype) is RU, you do not need to set this
parameter.
1. Set the Peer ID with the MAC address of the MU. Only use the last 8 digits of the MAC address.
#> peerid de1B7842
Success.
#>
2. Set channel and polarization. (in this example set the channel to 23 and polarization to H).
#> freq 1 h
Ch# 1 h (4950 MHz)
Success.
3. Set default Opmode to “ON.”
#> defaultopmode on
Success.
4. Turn Opmode “ON.”
#> opmode on
Success.
Establishing a Wireless Link
If the MU and RU are properly configured and in opmode “ON”, the two radios will automatically begin the
authentication process and become connected. To determine if the two radios are connected, type the sysinfo 2
command.
Example:
#> sysinfo 2
********************************* 2 *********************************
[Opmode] off [Default Opmode] off
[Active Channel] 1 h [Freq] 4950 MHz
[Speed] 24 Mbps [Tx Power] 0 dBm [Power Range] -4..19 dBm
[Tx MIR] 50000 Kbps
[ARQ] on
[Encrypt] off [Key] 0011 2233 4455 6677 8899 AABB CCDD EEFF
[Peer ID] DE1B7850 [Status] connected [RSSI] -49 dBm
Success.
#>
Configuration
Trango Broadband Wireless — ATLAS4900 page 11
The [status] field indicates whether the MU and RU are connected or disconnected. If connected, the MU and RU will
automatically start passing Ethernet traffic over the wireless link.
Changing IP Address
Use the ipconfig command to change the radio’s ip address, subnet mask and gateway.
Syntax: ipconfig [<ip> <subnet> <gateway>]
Example:
#> ipconfig 10.8.2.140 255.255.255.240 10.8.2.129
New configuration: [ip] 10.8.2.140 [subnet mask] 255.255.255.240 [gateway]
10.8.2.129
save and activate ? (y/n) [ATTN] Telnet session will be terminated in 30
seconds.
Success.
#>
LEDs
LEDs are visible on the unit’s PCB between the reset button and the RJ-45 connector. The function of each
LED is described below:
LNK (green)
Green: On solid for an established 10BaseT or 100BaseT Ethernet Link.
SPEED
Green: Solid if 100BaseT, Blinks only if there is activity (TX or RX) on the network when a 100 MBit
connection is established. Off if a 10BaseT connection is established or if there is 10BaseT activity.
RSSI (4 LEDs)
Amber: Four LEDs
In all modes except “Survey”, the unit’s four yellow LEDs indicate the level of RF signal being
received from a VALID MU or RU as appropriate.
Yellow LED 1 : Begins blinking when RSSI is greater or equal to –90 dBm. On continuously at –85
dBm. This is the Leftmost LED
Yellow LED 2 : Begins blinking when RSSI is greater or equal to –80 dBm. On continuously at –75
dBm.
Yellow LED 3 : Begins blinking when RSSI is greater or equal to –70 dBm. On continuously at –65
dBm.
Yellow LED 4 : Begins blinking when RSSI is greater or equal to –60 dBm. On continuously at –55
dBm. This is the rightmost LED.
If no VALID MU or RU signal is detected the LEDs will not be on at all.
In addition, these 4 LEDs shall flash ON for 2 seconds, then OFF for 2 seconds to indicate the 'factory
reset' button has been activated and the reset successful.
ASSOCiation LED (green):
The ASSOC led blinks at the following rates:
- Once every second when unit is powered on but opmode is OFF.
Configuration
Trango Broadband Wireless — ATLAS4900 page 12
- Twice per second while in opmode ON and scanning for an MU or RU.
- Solid after unit is associated with the RU or MU.
RF Link Loopback Test (linktest command)
The linktest command tests the throughput and packet error rate (PER) on the current channel for each direction at all
speeds and reports results. This command also provides RSSI for both ends of the wireless link. The command can be
run from either the MU or the RU.
In running the linktest command the user must specify the modulation speed for each end of the link.
Command format: linktest <loc speed> <peer speed>
Valid modulation speeds are: 6,12,18,24,36,48, and 54 Mbps. Lower speeds will result in fewer dropped packets.
Example:
# linktest 24 24
local tx rate = 24 Mbps
peer tx rate = 24 Mbps
packet size = 1600 bytes
# of packets per period = 1000
# of Cycle = 10

Success.
#>
In this example the linktest was run at 24 Mbps at each end of the link. The results indicated 10 cycles of 1000 packets
were transmitted and received from each end of the link without error. Actual achievable throughput is measured at 22
Mbps.
Link Speed & Power Settings
Users may change the radio’s over-the-air data rate and conducted output power using the speed and power
commands. Keep in mind that the lower data rates offer higher receiver sensitivity and higher allowable
conducted RF power in the ISM band. The following table shows the relation between speed settings, receiver
sensitivity, and allowable maximum power settings for each band. The lowest power setting for all bands in –4
dBm.

Chapter 4 Deployment & Installation
Once you are familiar with the basic operation of the radios you are ready for deployment in the field. The deployment process
consists of the following steps:
• Site Selection
• Site survey at MU and RU sites
• MU installation
• RU installation and antenna alignment
• Link test
Site Selection
Proper site selection for your MU will help ensure a successful deployment. Site selection will depend on a wide variety of
factors, but from the radio’s performance standpoint, please consider the following:
• Path from MU to RU should provide unobstructed line-of-sight (LOS), thus it is advisable to place MU as high as
possible on a tall building or tower.
• Ethernet cable limit is 100 meters from Ethernet device (router, switch) to radio.
• Radios should never be deployed without proper grounding.
• Consider nearby sources of interference that could degrade the performance of the radio. Mount radios as far from
sources of interference as possible.
Site survey
The radios provide an on-board site survey tool which measure the average and peak noise levels on any given channel.
To use the survey tool, the radio must be in Opmode “OFF.” The survey can be performed for any specified amount of
time (in seconds), and for either the horizontal or vertical polarization.
Prior to performing the site survey, place the radio in the installation spot, and aim the radio in the desired direction.
After the specified period, the results of this command will provide you with a listing of each channel in the band, the
average signal received, and the maximum signal received during the survey period.
Example:
#> survey
Press any key to stop.
noise floor (peak/avg dBm) rssi by pkt (peak/avg dBm)
0> -97 / -98 n/a
1> -97 / -98 n/a
2> -97 / -98 n/a
3> -97 / -98 n/a
4> -97 / -98 n/a
5> -97 / -98 n/a
6> -97 / -98 n/a
7> -97 / -98 n/a
8> -97 / -98 n/a
Ch 1 h 4950 --> -97 / -98 n/a
Success.
Channel Planning
Based on the results of the site survey at each end of the link, choose a channel which offers the lowest noise floor. In order to
reliably operate in the higher speed modes, clean spectrum is essential.
Deployment & Installation
Trango Broadband Wireless — ATLAS4900 page 17
RSSI Command and Antenna Alignment
Once the site survey is completed, you are ready to install your radios. Typically it is best to install the MU first. To
properly align the radios, use the built-in RSSI tool to achieve maximum signal strength.
1. Ensure MU and RU are in Opmode “ON.”
2. Connect to the RU.
3. Login and type the command rssi. As you read the RSSI, move the antenna in
the horizontal and vertical planes until the maximum RSSI reading is achieved
4. If it is not possible to receive an adequate RSSI reading, it may be necessary to
reorient the MU (up/down, left/right), to increase the output power of the MU, or
to move the RU to a location with better line-of-sight conditions to the MU.
5. Once you are satisfied with the RSSI reading, tighten down the RU in the
optimum position.
Example:
#> rssi
Press any key to stop.
0> MU -75 dB RU -75 dB Connected
1> MU -75 dB RU -75 dB Connected
2> MU -73 dB RU -73 dB Connected
3> MU -72 dB RU -71 dB Connected
4> MU -70 dB RU -70 dB Connected
5> MU -70 dB RU -69 dB Connected
6> MU -69 dB RU -70 dB Connected
7> MU -70 dB RU -70 dB Connected
8> MU -70 dB RU -70 dB Connected
9> MU -67 dB RU -68 dB Connected
10> MU -67 dB RU -67 dB Connected
Success.
Users can also view the RSSI LEDs on the bottom of the radio. See the configuration section of this manual for more
information.

Port Plug and Port Plate
Prior to deployment, insert the silicone port plug around the Cat-5 Cable and insert into the radio’s port opening. Next,
screw the port plate over the silicone plug as shown in the photographs below.
Mounting Hardware
Radios are supplied with mounting hardware for pole installations. See diagram below for proper use of the mounting
hardware.

Grounding
Proper mounting of the radio includes consideration for grounding. Please note that if the radio is attached to a metal pole that
is earth-grounded, no other grounding is necessary. If the radio is not earth-grounded via the mounting bracket, you must
attach a grounding wire to the grounding stud on the radio as in the adjacent diagram.
Cabling and Weather Considerations
Shielded twisted pair Cat-5 cable is recommended for all installations. The shield within the Cat-5 cable does not need to be
grounded if the radio itself is grounded. It is important to consider that most Cat-5 cable will deteriorate over time if exposed
to the weather (especially direct sunlight). It is recommended that installers place all Cat-5 cables inside conduit. Plastic
conduit is sufficient. If metal conduit is used, it is not necessary to use shielded Cat-5 cable.
Weatherizing
!
!
Important! Please note that the silicon strain relief has a small gap when the cable is
installed. This is normal .
It is important to provide strain relief and drip loop for STP Cat-5 cables. Do not mount the
radio upside down as water will enter the bottom of the radio and cause permanent damage
!
Important! The Power-over-Ethernet injector is not a weatherized device and must be
located either indoors or in a weather-protected cabinet.

Chapter 5 SNMP
The Atlas supports SNMP (Simple Network Management Protocol). Network management consists of the following 3
categories: configuration, Link and Association monitoring and Alarms. Besides this proprietary Management
Information Base (MIB) the Atlas also supports a large part of the MIB-II OIDs.
Review the Trango MIB (TRANGO-P5M-MIB.mib) available on our website for the complete listing of all MIB objects
available.
These capabilities allow the system administrator to provide superior service through higher network accessibility and
integrated performance monitoring.
Depending on your Network Node Manager (NNM) it may be necessary to append a “.0” onto the end of each of the
OIDs listed below for proper operation.

Chapter 6 Firmware Upgrade Procedure
Trango Broadband Wireless will from time to time release firmware upgrades for the Atlas series radios. The latest
released firmware can be downloaded from http://www.trangobroadband.com/support/downloads.htm.
Firmware releases consists of two files: Main image firmware and Web (HTTP interface) firmware.
Firmware File Names
Firmware files are released in the format shown below. This example consists of main image and web firmware versions
1.0a6.
Main Image: p5m_1p0a6D05031505_Pupgrade
Firmware Version: 1p0a6D05031505
File Size: 1868288 bytes
Web web_1p0a6D05031505_Pupgrade
File Size: 131584 bytes
Firmware Upgrade Password
The firmware filenames include the upgrade password (the characters after the ‘_P’ in the file name) The default
upgrade password in the Atlas radios is upgrade. Users may change the upgrade password within the radios using the
password upgrade command. Firmware release files from Trango Broadband Wireless will always be names with the
default upgrade password of upgrade. If the user changes the upgrade password in the radio, then the firmware file name
must be changed as well in order to upgrade the radios.
Upgrade Procedure
1. Place firmware files in easily accessible path in your computer.
2. In order to provide the most stable wireless conditions possible during the upgrade process it is recommended to
set the radio speed to the minimum (6 Mbps) in both the MU and RU. Turn autorateshifting off during the
upgrade.
3. Turn on the radio’s tftp daemon
4. From computer’s command prompt, tftp the firmware file into the radio using binary mode.
5. After file is successfully tftp’d to the radio, the radio will automatically reboot itself and load the new firmware
IMPORTANT: DO NOT POWER CYCLE OR INTERUPT THE REBOOT PROCESS IN ANY MANNER.
WAIT AT LEAST THREE MINUTES TO ENSURE AUTOMATIC REBOOT COMPLETION. LOSS OF
POWER DURING THE REBOOT SEQUENCE WILL RESULT IN A CORRUPTED/INCOMPLETE
FIRMWARE LOAD WHICH WILL REQUIRE REFLASHING AT THE FACTORY.
6. Repeat process for other radio
7. Repeat process for web file.
Example 1 Upgrade main image firmware to 1.0a6
