This section explains the process for making a CLI connection.
1. Understanding CLI options
See Understanding CLI/serial connections on page 132.
2. Establishing a CLI /serial link with the node
A serial link for CLI node management is created from the laptop to the node.
See Establishing the CLI/serial connection on page 135.
3. Optionally establishing a CLI/telnet/craft Ethernet session with the node.
CLI/telnet/craft Ethernet is required when you need multiple simultaneous CLI sessions with the node.
a. Configuring IP on the craft Ethernet and laptop on page 137
b. Establishing the CLI/telnet/Ethernet connection on page 138
This procedure is complete.
Understanding CLI/serial connections
The command line interface (CLI) enables text-based, command-oriented management of the IP-RN 8000.
The CLI can be accessed in three ways:
• CLI/serial — Direct connection to the craft serial port on the BIO/SC, RM, and TFU module serial craft
ports
• CLI/telnet/craft Ethernet — A laptop’s Ethernet adapter is connected to the craft Ethernet port on the
BIO/SC module, IP is configured on the laptop on the craft Ethernet, and a telnet session provides CLI
access.
• CLI/telnet/backhaul — When the node is fully configured and functional backhaul links, you can telnet
to the node’s node IP address from anyplace on the IP network.
CLI/serial
CLI/serial is the simplest form of CLI connection. It is only available when you are local to the serial port.
This form of CLI connection is required during initial phases of commissioning. For example, you must use
CLI/serial to set the craft Ethernet IP address if you then want to use CLI/telnet/craft Ethernet. You can only
have a single CLI/serial connection to a node at a time when using CLI/serial. CLI/serial connection requires
a cable to link the serial craft port on the network element to a serial port (typically a COM port) on a laptop
or other device. Launch a terminal emulation program on the laptop (such as Hyperterminal) and configure
the communications settings appropriately (see Establishing the CLI/serial connection on page 135).
CLI/serial on redundant systems
CLI/serial connection is made by connecting a laptop running terminal emulation software to the serial port
on the BIO/SC module. Redundant systems have two BIO/SC modules. In almost all cases, you should plug
the serial cable into the active BIO/SC module.
You can tell which BIO/SC module is active by examining the LEDs on the BIO/SC modules. See
Understanding the Base Input Output/System Controller module on page 22.
Understanding craft Ethernet connection to the node
IP-RN 8000 Installation & Commissioning Guide 133
When configuring the node from the active BIO/SC module, all configurations apply to the entire node.
However, there are some cases where you need to plug the serial cable into the serial port on the inactive
BIO/SC module. For example, if the node uses Ethernet backhauls, the only way to loopback test the
Ethernet link associated with the inactive module is to plug the serial cable into the serial port on the inactive
BIO/SC module.
CLI/telnet/craft Ethernet
CLI/telnet/craft Ethernet is made by connecting an Ethernet adapter on your laptop to the Ethernet craft port
on the BIO/SC module, either directly using a cross over cable or through a switch or hub using straight
through cables. You must configure appropriate IP addresses and masks on the BIO/SC Ethernet port (using
CLI/serial) and on the laptop Ethernet port. Then you launch telnet and open a CLI session with the node
using the node IP address or the craft Ethernet IP address.
Because you can open multiple CLI sessions at a time using telnet, this method is required during certain
phases of the commissioning procedure.
CLI/telnet/backhaul
CLI/telnet/backhaul is made through the existing backhaul network. This assumes a normally operating
network with backhaul links that are up and running and IP addressing that is fully configured and correct.
You can open a telnet session with the node’s node IP address from any location support by the IP network
design.
Understanding craft Ethernet connection to the node
The BIO/SC module has two craft ports:
• Female DB-9 for serial connections
• RJ-45 Ethernet
For information about BIO/SC craft ports, see Understanding the Base Input Output/System Controller
module on page 22. There are two ways to connect a laptop Ethernet to the BIO/SC craft Ethernet (see
Figure 21):
• Directly using a cross-over cable
• Indirectly using an Ethernet switch and two straight-through cables

Establishing the CLI/serial connection
This procedure explains how to connect the laptop’s COM port to the active BIO/SC’s craft serial port and
how to start the CLI/serial session. It is assumed the IP-RN 8000 is powered on.
Requirements
• A laptop running at least Microsoft Windows 98
• The laptop must have either sufficient batteries to run throughout the commissioning process or it must
have a power source and appropriate power adapter
• Terminal emulation software, such as Hyperterminal, which comes with Windows
• Serial cable with male DB-9 connector for attaching to the female DB-9 on the BIO/SC side and a
connector on the laptop side that is appropriate for the laptop’s serial port
Procedure
1. Open the PC shelf on the inside of the front door and place the laptop securely on the shelf.
See Opening the PC shelf on page 201.
2. Boot up the laptop.
3. Retrieve the CLI cable.
4. Determine which BIO/SC module is active.
If there is only a single BIO/SC installed, it is installed in slot 3 and is active.
If there are two BIO/SC modules installed, check the ACTIVE LEDs to determine which one is active
and which is standby. See Understanding the Base Input Output/System Controller module on page 22.
Typically the primary BIO/SC module in slot 3 is the active module and the redundant BIO/SC module
in slot 7 is the standby module.

Running the commissioning script
About this chapter
This chapter describes how to run the commissioning script to configure the node for normal
operations. This chapter contains the following sections:
•Understanding the scripting process on page 146
•Initializing the node to receive a file with kermit on page 147
•Transmitting a script from a laptop to the network element on page 148
•Verifying the script file is on the node on page 154
•Running the script on page 155
Chapter 12 ● Running the commissioning script
146 Release 2.0, 910056 Rev01d
Understanding the scripting process
This process explains all steps and procedures to follow when transferring a script to a node and running the
script.
1. Understanding scripts and script transfer options
This procedure explains how to use the kermit protocol over a serial link to the node to transfer the
script file to the node. This is the simplest method. However, you can also use FTP to the node if you
have an IP connection.
See Understanding scripts on page 146.
See Understanding script transfer options on page 147.
2. Initializing the node to receive the script file with kermit
Using CLI, enter the node shell and prepare the node to receive the file from the laptop over the serial
connection using the kermit protocol.
See Initializing the node to receive a file with kermit on page 147.
3. Initializing the laptop and transmitting the script file with kermit
Launch HyperTerminal and send the file using the kermit protocol.
See Transmitting a script from a laptop to the network element on page 148
4. Verifying the script file is on the node
Verify the script file was transferred to the node.
See Verifying the script file is on the node on page 154.
5. Running the script file on the node
Run the script file on the node to update the node’s operating configuration
See Running the script on page 155.
This procedure is complete.
Understanding scripts
Scripts are collections of CLI commands stored in a text file. The script is created by centralized network
planners and provided to the installer/commissioner. The script is transferred to the node using
Hyperterminal (or any application that supports the kermit file transfer protocol) or FTP and executed with
the CLI copy command to update the node’s operating configuration. The write command should occur
at the beginning of the script to copy the current configuration to disk. If there is an error during script
execution and you reboot the network element, the configuration is restored.
Understanding script transfer options
IP-RN 8000 Installation & Commissioning Guide 147
Understanding script transfer options
There are two ways files can be transferred to a node:
• Through the BIO/SC craft serial port using the kermit protocol
• Through the craft Ethernet or the backhaul using FTP
There are typically two types of files you need to transfer to the node:
• A software release for upgrading node operating software
• A script file for updating the operating configuration of the node
Which method is used depends on the following considerations:
Serial link requires less configuration
The kermit over the serial connection requires less configuration than FTP. No connection to the craft
Ethernet is required, and no configuration of IP addresses is required. All that is required is a serial cable
connecting the laptop COM port to the BIO/SC craft serial port. However, if you already have an IP
connection to the node, then FTP is a straightforward and convenient way to transfer either script files or
software releases to the node.
Remote file transfer requires FTP
The serial link can only be used if you are at the same physical location as the node. If you are not at the
same physical location, you can transfer files using FTP.
Use FTP to transfer large files such as software releases
Large files such as software releases should be transferred to the node using FTP through the craft Ethernet
or through the backhaul because it can take hours to transfer such large files through the serial port.
Initializing the node to receive a file with kermit
This procedure explains how to initialize the node to receive a file transmitted from a laptop connected over
a serial connection using the kermit protocol.
The script file must be transferred to the node before it can be executed on the node.
This procedure assumes you have an operational CLI connection to the active BIO/SC module. For
information, see Establishing the CLI/serial connection on page 135.
You must also have the script file on your laptop.
1. Use shell to change to the command line shell as follows:
AIRVANA-03>shell
The following prompt displays:
AIRVANA-03(shell)(disk0:/)>
2. Use ls to check whether the config directory exists:
AIRVANA-03(shell)(disk0:/)>ls
Chapter 12 ● Running the commissioning script
148 Release 2.0, 910056 Rev01d
3. Examine the output from the ls command. If there is no config directory, create the config
directory by entering the following:
AIRVANA-03(shell)(disk0:/)>mkdir config
4. Move to the config directory by entering the following:
AIRVANA-03(shell)(disk0:/)>cd config
The following displays:
AIRVANA-03(shell)(disk0:config)>
5. Prepare the node to use kermit to receive the file by entering the following:
AIRVANA-03(shell)(disk0:config)>kermit receive <filename>
Where <filename> is the name you want the script file to have after it is received on the node
through kermit. This is not necessarily the same file name that the script file has on the laptop.
The CLI is now locked waiting to receive a file. Now you must prepare the laptop and transmit the
script file using kermit.
This procedure is complete. Go to Transmitting a script from a laptop to the network element on page 148.
Transmitting a script from a laptop to the network element
This procedure explains how to transmit a script file from the laptop to a node that is already initialized to

154 Release 2.0, 910056 Rev01d
Verifying the script file is on the node
This procedure explains how to verify the script file has been transferred successfully to the node and how to
leave the command shell.
1. Look at the CLI output.
If the kermit file transfer failed, an error message displays. If it has failed, attempt the transfer again by
going to Initializing the node to receive a file with kermit on page 147.
2. Check the contents of the disk0:/config directory with the ls command to see whether the script file is
present as follows:
AIRVANA-03(shell)(disk0:config)>ls
The list of files in the directory is displayed with the size of each file. Ensure the script file you
transferred is present and has a file size greater than 0.
Note that the file name is the name you entered in the CLI command kermit receive
<filename>, not the file name of the file before it was transmitted from the laptop.
If the file is not present, attempt the transfer again by going to Initializing the node to receive a file with
kermit on page 147.
3. Use the exit command to leave the command shell and return to the normal CLI prompt, as follows:
AIRVANA-03(shell)(disk0:config)>exit
The following prompt displays:

The CLI prompt changes to the Privilege EXEC prompt, as follows:
AIRVANA-03#
2. Run the commissioning script by using the CLI copy command to copy it to
system:running-config, as follows:
AIRVANA-03#copy disk0:/config/<scriptFileName> system:running-config
where:
•copy is the CLI copy command
•disk0:/config/ specifies the required path to the script
•<scriptFileName> is the name of the script file
•system:running-config is the required destination file name
Always specify system:running-config as the destination file when using the CLI copy
command to run the commissioning script.
For example: copy disk0:/config/nodea.txt system:running-config
The node runs the commissioning script you specified. When the script finishes executing, the CLI
displays the script done message, as follows:
AIRVANA-03#script done
If the script fails to execute successfully or encounters errors, the CLI displays an appropriate error
messages and the script stops running at the point where the faulty CLI command tried to execute.
3. Return to the base command prompt by typing exit followed by the <ENTER> key twice times, as
follows:
AIRVANA-03#exit
AIRVANA-03>

Understanding the backhaul link loopback test process
This process explains the steps you should follow for performing loop back tests. Loopback testing each
backhaul link is recommended to ensure correct installation and operation at the physical layer.
1. Understanding the backhaul loopback process
This section explains the T1/E1 loopback testing process.
See Understanding backhaul loopback testing on page 159.
See Understanding a typical T1/E1 backhaul network on page 160.
See Understanding Ethernet loopbacks on page 160.

See Removing physical loopbacks on page 168
This procedure is complete. You must complete the commissioning. Go to Understanding the
commissioning completion process on page 188.
Understanding backhaul loopback testing
IP-RN 8000 Installation & Commissioning Guide 159
Understanding backhaul loopback testing
Loopback testing each backhaul link verifies the backhaul installation was performed correctly and verifies
physical layer operation before the technician leaves the site. During manufacturing the backhaul interfaces
are loopback tested to the punch block, ensuring all internal components function properly. Loopback testing
during installation can be performed to verify the correct wiring into the punch block and the external
physical infrastructure.
The extent of the loopback test (the amount of equipment and cabling that is tested) depends on where the
physical loop back is installed. The farther away from the node the loop back is installed, the greater the
extent of the test.
Airvana recommends installing the loopback at least as far as the far end of each backhaul cable exiting the
cabinet. Installation at that point includes the backhaul cable’s wiring into the backhaul punch block and the
backhaul cable itself.
The technician must have appropriate equipment and materials for installing and performing loopbacks.
NOTE
The loop back testing described here does not include backhaul
circuits, only physical layer functionality at the cell site.
Backhaul circuits must undergo end-to-end testing and
acceptance at the time they are brought up by the service
provider.
NOTE
Ethernet loopbacks cannot be installed at the far side of a router,
switch, FRAD, or other edge device.
NOTE
Maximum cable lengths must be considered when installing
loopbacks. Loopbacks double the length of a cable (the cable
length now equals the outgoing leg plus the return leg, or twice
the physical cable length). Failure to consider this factor can
result in failed loopback tests for cables that are flawless.
Chapter 13 ● Loopback testing backhaul links
160 Release 2.0, 910056 Rev01d
Understanding a typical T1/E1 backhaul network
Figure 22 shows a typical network in which T1s/E1s are used for backhaul link(s).
Figure 22 A typical T1/E1 backhaul network using DSXs (digital cross connects, T1/E1 multiplexors, or
similar)
Understanding Ethernet loopbacks
Like the T1/E1 loopback test, the Ethernet loopback test has two parts:
• Physically loopback the Ethernet
• Run the loopback test
The loopback can be done externally on the cable by physically connecting the receive wires (RXs) to the
transmit wires (TXs). The loopback can also be done internally on the hardware transceiver chip. Looping
back internally on the transceiver chip only tests limited hardware functionality and does not test the cable
connection or the punch down block. Looping back externally tests more. The Ethernet loopback test is not
a standard function of Ethernet but is a value-added proprietary feature.

Looping back T1/E1 backhaul links
This section explains options for installing physical loopbacks when T1 or E1 backhaul link(s) are deployed
at the cell site. Because Airvana does not specify the external T1/E1 equipment used at cell sites, some
details of looping back the T1/E1 cables are site-dependent. Depending on the equipment deployed at the
site at the time of loopback testing, the location of the installed physical loopback will vary. (See also
Understanding backhaul loopback testing on page 159.) The technique used to create the loopback will also
vary depending on installed third-party equipment.
1. If the backhaul cables that exit the cabinet are connected to a DSX (or an equivalent type of equipment),
the physical loopback should be installed on the IP-RN 8000 side of the DSX (or equivalent of
equipment). Use methods and materials to install the loopback that are appropriate to the third-party
equipment.
2. If the T1/ E1 backhaul cables exiting the cabinet hang free at the far end, build a physical loopback
appropriate to the cable type and install it at the far end of the cable.
This procedure is complete. Go to Entering diagnostic mode and configuring test parameters on page 163.
NOTE
• Physical loopbacks are created by physically
connecting the positive transmit wire to the positive
receive wire and connecting the negative transmit
wire to the negative receive wire.
• Loopbacks must be installed on each and every T1/
E1 backhaul cable.
NOTE
Maximum cable lengths must be considered when installing
loopbacks. Loopbacks double the length of a cable (the outgoing
leg along the cable and the return leg). Failure to consider this
factor can result in failed loopback tests for cables that are
flawless.

Chapter 13 ● Loopback testing backhaul links
162 Release 2.0, 910056 Rev01d
Looping back Ethernet backhaul links
This section explains how to install the physical loopbacks when Ethernet backhaul links are used. If the
Ethernet backhaul cable is connected to a patch panel (or another passive, pass-through device), you can
install the loopback at the far side of it and thereby include the patch panel in the test.
Because Airvana does not specify the Ethernet cable/connector types, the details of looping back the
Ethernet cables are site-dependent. Typically, Ethernet backhaul cables installed into the backhaul punch
block have an RJ-45 jack at the far-end. This section provides the pin-out for the RJ-45 jack.
1. If the Ethernet at the point of the loopback installation has an RJ-45 connector on the far end, build a
loopback jack using the pin-out in Table 23.
2. If the Ethernet backhaul(s) have a different connector, build a loopback jack as appropriate.
3. Install the loopback connectors onto the far end of each Ethernet cable.
NOTE
You cannot loopback the Ethernet at the far side of most network
devices, including switches, routers, and FRADS.
NOTE
• Physical loopbacks are created by physically
connecting the positive transmit wire to the positive
receive wire and connecting the negative transmit
wire to the negative receive wire.
• Loopbacks must be installed on all Ethernet backhaul
cables. There is one Ethernet backhaul cable on
non-redundant systems; there are two on redundant
systems.

IP-RN 8000 Installation & Commissioning Guide 163
This procedure is complete. Go to Entering diagnostic mode and configuring test parameters on page 163.
Entering diagnostic mode and configuring test parameters
This procedure explains how to initiate a hard reset and use the CLI to enter diagnostics mode, and how to
configure the diagnostics mode for E1 links, if E1 backhaul links are deployed (see step 4). It is assumed
that you already have a CLI link to the node through the serial port on the active BIO/SC module. (See
Establishing the CLI/serial connection on page 135.)
Requirements
No tools or materials are required.
Procedure
1. Ensure the CLI session is active by pressing the <ENTER> key on your CLI laptop. A new command
prompt appears indicating the session is active.
If the session is not active, see Establishing the CLI/serial connection on page 135.
2. Use the reset command to reboot the node as follows:
AIRVANA-03>enable
AIRVANA-03#reset
This causes the node to reboot and to run hardware diagnostics.
After hardware diagnostics run, a diagnostics countdown occurs. This countdown enables you to enter
diagnostics mode by pressing the <SPACE BAR> key three times during the countdown. The
countdown numbers are transmitted out the serial port and are visible in your CLI session.
3. During the countdown, press any the <SPACE BAR> key three times .
This causes the RN to enter diagnostics node. Loopback test commands are only available in
diagnostics mode. The diagnostic mode command prompt is”
BIOSC_3>
Where “3” is the slot number.
4. If the backhaul links are E1, enter the following three commands to configure the E1 diagnostic mode:
BIOSC_3>writeee 7FF 02
BIOSC_3>writeee 100 0
BIOSC_3>reset
Resetting the node causes another reboot. You must enter the diagnostics mode by pressing the
<SPACE BAR> key three times during that countdown as you did in step 3 in order to stay in
diagnostics mode and to continue with loopback testing.
This procedure is complete. Go to Performing external loopback tests on backhaul links on page 164.
Chapter 13 ● Loopback testing backhaul links
164 Release 2.0, 910056 Rev01d
Performing external loopback tests on backhaul links
This procedure explains how to perform loopback tests on backhaul links. It is assumed an external
loopback has already been installed on each backhaul. (See Looping back T1/E1 backhaul links on page 161
and Looping back Ethernet backhaul links on page 162). A CLI session must be active. (See Establishing the
CLI/serial connection on page 135.) The node must be in diagnostic mode. (See Entering diagnostic mode
and configuring test parameters on page 163.) If the backhaul is T1 or E1, diagnostic parameters must have
been set. (See Entering diagnostic mode and configuring test parameters on page 163.)
1. Enter the CLI command to start the loopback test.
The command is: commsend <number of tests> <ports>
Where:
•<number of tests> specifies the number times each port is to be tested. The valid range is
between (0 – 100000).
•<ports> specifies the names of the ports to be tested. See Table 24.
For example, the following command would start the loopback test for a system with two E1 backhaul
links: commsend 10 T1 T2
Table 24 Specifying the backhaul links to be tested
<ports>Indicates the following ports to be tested
T1 The first T1 or E1 backhaul
T2 The second T1 or E1 backhaul
T3 The third T1 or E1 backhaul
T4 The fourth T1 or E1 backhaul
FENET1 The primary Ethernet backhaul
NOTE
If your node uses two Ethernet backhaul links (a primary and a
redundant), you need to check them separately. First, establish a
CLI connection with the primary BIO/SC and run the loopback
test, then establish a CLI connection with the redundant BIO/SC
and run the loopback test. You can simply unplug the laptop CLI
cable from the primary BIO/SC craft port and plug it into the
redundant BIO/SC craft port. The CLI command to run the test is
the same: commsend <number of tests> fenet1.

166 Release 2.0, 910056 Rev01d
Troubleshooting failed backhaul links
This procedure explains how to run the internal loopback test on backhaul links that failed the external
loopback test. This section also outlines what to do based on the test results: If the internal loop back passes,
troubleshoot the cables and loopback devices. If the internal loopback fails, the node may be faulty and you
should call Airvana.
This procedure assumes the node is in diagnostic mode, a CLI session is active, and the preceding loopback
procedures have been completed.
1. If the backhaul links are T1 or E1, enter the following CLI command to specify the backhaul links you
want to set to internal loopback mode:
BIOSC>mmb <port memory locations> 04
Where:
•<port memory locations> are the backhaul links to place into internal loopback mode. See
Table 25.
For example, the following command sets the second T1 or E1 backhaul to internal loopback mode:
BIOSC>mmb f500010a 04
2. If the backhaul links are Ethernet, enter the following CLI command:
BIOSC>poke874 fenet1 13 803c
3. Run the internal backhaul test on the interface(s) you have set to internal loopback mode with the
following CLI command:
BIOSC>commsend <number of tests> <ports>
Where:
•<number of tests> specifies the number times each port is to be tested. The valid range is
between (0 – 100000).
•<ports> specifies the names of the ports to be tested. See Table 26.
Table 25 Specifying the backhaul links to be set to internal loopback mode
<port memory

Frames without valid Test ID : x
Frames with invalid Data : x
Frame Error Rate : x
Error Counters
Rx Frame Length Violations ... x
Rx Non-octet alignment ... x
Rx Abort Frames ... x
Rx CRC Errors ... x
If the Number of Received Frames does not equal the Number of Transmitted
Frames, or if there are any errors counted, the node has a fault and you need to contact Airvana. This
is the end of this procedure.
If the Number of Received Frames does equal the Number of Transmitted Frames
and there are no errors, you must troubleshoot the following:
• the backhaul cable
• the physical loopback installed earlier in the loopback testing process
• the backhaul wiring into the punch block
• any external equipment the backhaul cable is attached to, for example a digital cross connect
5. Exit diagnostics mode
Enter the following command to reset the node:
BIOSC>reset
Allow the node to reboot to completion, skipping the diagnostic mode required for loopback testing.
This procedure is complete. Go to Removing physical loopbacks on page 168.

170 Release 2.0, 910056 Rev01d
Understanding the transmit power calibration process
This process explains the procedures to measure antenna jumper attenuation and to calibrate transmit power
for each sector accordingly.
1. Understanding calibration purpose and requirements
See Understanding calibration purpose on page 171.
See Understanding requirements on page 171.
2. Opening two CLI/telnet sessions
Simultaneous CLI sessions are needed to the local IP-RN 8000 and the remote IP-RNC 8500. This
requires that the laptop is connected to the BIO/SC craft Ethernet and that IP is configured
appropriately.
See Understanding the need for simultaneous CLI sessions on page 171.
3. Enabling the BTS and checking the connection with the IP-RNC 8500
Enable the BTS function of the IP-RN 8000 and verify the connection with the IP-RNC 8500.
See Enabling the base station and checking the IP-RNC 8500 on page 172.
4. Verifying GPS status
Verify that GPS is locked and time is acquired.
See Verifying GPS status on page 172.
5. Disabling all sectors
All sectors must be disabled (transmission must be stopped) before continuing with the calibration.
See Disabling all sectors on page 174.
6. Calibrating each sector’s power transmission offset
Perform the following procedures in sequence for each sector deployed:
a. Attach the test equipment to the sector’s transmit jumper antenna cable
See Attaching the sector’s test equipment on page 176.
b. Enable and blossom the sector
See Enabling and blossoming the sector to be calibrated on page 178
c. Start the FTAP test for the sector
See Starting FTAP for the sector on page 179.
d. Measure the power loss at the end of the sector’s transmit antenna jumper cable at three levels and
find the average loss.
See Measuring power loss for the sector on page 180.
e. Set the sector’s transmit power.
See Setting the sector’s transmit power on page 181.
f. Verify the sector’s transmit power level
See Verifying the sector’s power level on page 182.
g. Shut the sector down, remove test equipment, and re-connect the antenna
See Completing the sector’s transmit power calibration process on page 183
This procedure is complete. You must run the commissioning script to configure the node for normal
operations. Go to Understanding the backhaul link loopback test process on page 158.
Understanding calibration purpose
IP-RN 8000 Installation & Commissioning Guide 171
Understanding calibration purpose
The purpose of the procedures in this chapter is to measure the power loss over the antenna jumper so that
you can adjust the transmission level for the sector appropriately to compensate.
Understanding requirements
The following are required to measure and calibrate the transmit power for each sector:
• The IP-RN 8000 must have been completely configured for normal operations with the commissioning
script.
• Backhaul links must be operative at the physical level and at the IP level providing connectivity to the
IP-RNC 8500 to which this IP-RN 8000 is homed.
• The IP-RNC 8500 to which this IP-RN 8000 is homed must be operating.
• You must know the management IP address of the IP-RNC 8500 to which the IP-RN 8000 is homed in
order to telnet to it.
Understanding the need for simultaneous CLI sessions
Calibrating transmit power requires two simultaneous CLI sessions, one to the local IP-RN 8000 and one to
the remote IP-RNC 8500. Simultaneous CLI sessions require a connection from the laptop to the BIO/SC
craft Ethernet port and that the appropriate IP configuration is completed. Once this connection is active,
you can open two CLI/telnet sessions, one to the local IP-RN 8000 and one to the remote IP-RNC 8500.
(Alternatively, you can use the CLI/serial connection to control the local IP-RN 8000 and use CLI/telnet to
control the remote IP-RNC 8500.)
Before proceeding, open these two CLI sessions. Opening the IP-RNC 8500 requires that you know and use
the IP-RNC 8500’s management IP address.
See Understanding the CLI connection process on page 132.

Procedure
1. Verify GPS is locked to a satellite with the following:
AIRVANA-03>show gps-health
The following displays:
GPS module is present
GPS Lock Status: Locked
Even Second: Valid
If the display shows any other values, GPS is not functioning properly. Troubleshoot the following:
• The TFU module containing the GPS module. Ensure that it is properly inserted in the chassis and
that its LEDs indicate normal operations.
• Verify that the GPS antenna jumper cables exiting the cabinet through the Rox System cabinet seal
are properly connected to GPS antennas and that those antennas are functioning properly.
2. Enter the following command to display the current UTC (Universal Time Coordinated) time as
reported by the GPS module:
AIRVANA-03>show gps time
The GMT time displays:
Current UTC Time read from the GPS: 19:32:18 07/01/02
Even-second is valid.
Verify the time displayed is correct.
If the correct time does not display, troubleshoot the GPS antennas and receivers.
This procedure is complete. Disabling all sectors on page 174.
NOTE
It can take 10 minutes after the GPS antenna is connected and the
TFU module is powered on for the GPS to acquire and display
the correct time.

and connector adapters
• Power meter with connector appropriate for coupler
• 1xEV-DO access terminal (AT)
Warnings
WARNING
You must have disabled the sector before continuing. Failure to
disable the sectors can result in EMI radiation that could cause
injury and could cause interference with other devices.
WARNING
Antenna cables emit radio frequency energy. Exposure to radio
frequency energy can cause burns or other health problems. Take
all appropriate precautions to avoid risk and danger.
WARNING
Do not touch or disconnect antennas when there is any chance of
a lightning strike. Injury or death can occur if lightning strikes an
antenna during installation.

178 Release 2.0, 910056 Rev01d
Enabling and blossoming the sector to be calibrated
This procedure explains how to enable the sector being calibrated and turn on (blossom) transmission for the
sector. This is needed for the AT to establish an active 1xEV-DO session with the IP-RNC 8500.
Requirements
• CLI session to the IP-RN 8000
• CLI session to the IP-RNC 8500
• A turned on 1xEV-DO AT
• All sectors are disabled
Procedure
1. Use the CLI session to the IP-RN 8000 to enable and blossom the sector being calibrated, as follows:
AIRVANA-03>enable
AIRVANA-03#configure
AIRVANA-03(config)#sector-element <sector-element>
Where: <sector-element> is element1/4/1 for sector1/alpha, element1/4/2 for sector2/
beta, element1/4/3 for sector1/gamma
AIRVANA-03(config-element)#tx-power 25
AIRVANA-03(config-element)#no shutdown
AIRVANA-03(config-element)#exit
AIRVANA-03(config)#exit
AIRVANA-03#exit
2. Verify the sector is up as follows:
AIRVANA-03>show sector-element
Name Carrier Sector CAI Channel Power Admin Oper
--------------------------------------------------------------------
element1/4/1 carrier1 sector1 IS-856 850 25 dBm UP UP
element1/4/2 carrier1 sector2 IS-856 850 35 dBm DOWN DOWN
element1/4/3 carrier1 sector3 IS-856 850 35 dBm DOWN DOWN
The sector you blossomed should have an Admin of UP and an Oper of UP.
This procedure is complete. Go to Starting FTAP for the sector on page 179.
Starting FTAP for the sector
IP-RN 8000 Installation & Commissioning Guide 179
Starting FTAP for the sector
This procedure explains how to get the UATI identifier for the AT that is required for the FTAP test and how
to start the FTAP test. Starting FTAP cause the IP-RNC 8500 to transmit a steady stream of data to the
specified AT using the current sector (only one sector at a time is enabled). This causes the IP-RN 8000 to
transmit to the AT at a steady rate, enabling power measurement and calibration.
Requirements
• A 1xEV-DO access terminal (AT)
• A CLI session to the IP-RN 8000
• A CLI session to the IP-RNC 8500
Procedure
1. Ensure the AT is turned on and has establisedh a 1xEV-DO connection.
How to do this depends on the type of AT. It may just require turning the AT on, or additional steps may
be required.
2. Use the CLI session to the IP-RNC 8500 to find the AT’s UATI as follows:
AIRVANA-07>enable
AIRVANA-07#show 1xevdo session all 1001 40
The following displays (the complete table is not displayed here):
UATI List
Inst UATI24 RATI ...
(Dec) (Hex) ...
---------------------------------------------------------------------
1 10 000003F2 ...
The UATI in this case is 000003F2.
If no UATI is displayed, there may be a problem with the AT or with the network. This test requires a
completely configured and operational IP-RAN network and an operational 1xEV-DO AT.
3. Still using the CLI session to the IP-RNC 8500, enter TAP configuration mode, as follows
AIRVANA-07#tap
4. Configure the TAP session with the UATI of the AT discovered above, as follows:
AIRVANA-07(tap)#user 0x3f2
Where: 0x indicates hexadecimal and 3f2 is the UATI found above (leading zeros are not required)
5. Start the FTAP test as follows:
AIRVANA-07(tap-0x3f2)#at-tx-mode ftap-loopback
AIRVANA-07(tap-0x3f2)#start ftap 3600
Where 3600 is the number of seconds the FTAP test runs without being intentionally stopped.
Using 3600, the FTAP test will stop in one hour. If you have not completed the calibration for this sector
by then, you must restart the FTAP test.
This procedure is complete. Go to Measuring power loss for the sector on page 180.

AIRVANA-03(config-element)#tx-power 25
AIRVANA-03(config-element)#no shutdown
These commands configure the first sector (identified by sector-element element1/4/1).
To configure sector 2, use: sector-element element1/4/2.
To configure sector 3, use: sector-element element1/4/3.
2. As a result of these commands, the sector transmission blossoms. Wait until the power meter shows a
stable power level. Find the differences between this detected power level and the configured transmit
power level (25 dB) and write it down. The detected power level should be somewhat less than the
transmit power level due to power lost over the antenna jumper cable and test equipment.
3. Change the transmit power level for the sector to 35 dBm using the following:
AIRVANA-03(config-element)#tx-power 35
4. The sector transmission blossoms. Wait until the power meter shows a stable power level. Find the
differences between this detected power level and the configured transmit power level (35 dB) and write
it down.
5. Change the transmit power level for the sector to 45 dBm using the following:
AIRVANA-03(config-element)#tx-power 45
6. The sector transmission blossoms. Wait until the power meter shows a stable power level. Find the
differences between this detected power level and the configured transmit power level (35 dB) and write
it down.
7. Find the average of the three numbers you calculated. Each of those calculations was the power loss at a
given transmit level. The average of those is the average power loss (without compensation for test
equipment) and is used to calibrate the power level of the transmission on this sector.
This procedure is complete. Go to Setting the sector’s transmit power on page 181.
Setting the sector’s transmit power
IP-RN 8000 Installation & Commissioning Guide 181
Setting the sector’s transmit power
This procedure explains how to calibrate the sector’s power transmission level using the results of the power
loss measurements taken in the previous procedure.
Requirements
• A CLI session to the IP-RN 8000
• The average dB loss for the sector calculated in the previous procedure
Procedure
1. Calculate the power loss parameter for the CLI command using the average power loss from the
previous procedure as follows:
a. Subtract the power loss of the power splitter and attenuator.
b. Round the result off to the nearest 1/8th (to the nearest 0.125)
For example, if the average dB power loss was 33.55 dB and the power splitter and attenuator have a
combined loss of 32 dB:
a. 33.55 — 32 = 1.55
b. 1.55 rounded to the nearest 1/8th is 1.625
So, the result is 1.625. This result is used in the next step.
2. Turn off the sector as follows:
AIRVANA-03>enable
AIRVANA-03#configure
AIRVANA-03(config)#sector-element element1/4/1
Use element1/4/2 for sector 2/beta and element1/4/3 for sector 3/gamma
AIRVANA-03(config-element)#shutdown
3. Set the transmit power level for the sector as follows:
AIRVANA-03(config-element)#pa-offset +1.625
Where +1.625 is the result calculated in step 1
4. Turn on the sector as follows:
AIRVANA-03(config-element)#no shutdown
AIRVANA-03(config-element)#exit
AIRVANA-03(config)#exit
AIRVANA-03#exit
This procedure is complete. Go to Verifying the sector’s power level on page 182.
Chapter 14 ● Calibrating transmit power
182 Release 2.0, 910056 Rev01d
Verifying the sector’s power level
This procedure explains how to verify the sector’s calibration.
Requirements
A CLI session to the IP-RN 8000
Procedure
1. At the CLI session to the IP-RN 8000, use the following commands to set the power level to 25 dBm:
AIRVANA-03>enable
AIRVANA-03#configure
AIRVANA-03(config)#sector-element element1/4/1
AIRVANA-03(config-element)#tx-power 25
AIRVANA-03(config-element)#no shutdown
These commands configure the first sector (identified by element1/4/1).
• To configure sector 2, use: sector-element element1/4/2.
• To configure sector 3, use: sector-element element1/4/3.
2. As a result of these commands, the sector transmission blossoms. Wait until the power meter shows a
stable power level and write it down.
3. Change the transmit power level for the sector to 35 dBm using the following:
AIRVANA-03(config-element)#tx-power 35
4. The sector transmission blossoms. Wait until the power meter shows a stable power level and write it
down.
5. Change the transmit power level for the sector to 45 dBm using the following:
AIRVANA-03(config-element)#tx-power 45
6. The sector transmission blossoms. Wait until the power meter shows a stable power level and write it
down.
7. Analyze the results to see if calibration is successful.
All three measurements should be within 1 dBm of the transmit power set with the tx-power
command after compensation for the power loss in the power coupler and attenuator pad.
• If all three results after compensating for the power splitter and attenuator pad are within 1 dB of
the power level set, the sector’s transmission power has been calibrated successfully.
• If any of the three results after compensating for the power splitter and attenuator pad are not within
0.5 dBm of the power level set, the sector’s transmission power has not been calibrated
successfully.
8. At this point you can optionally connect a radio frequency spectrum analyzer to the Tx sample port on
the PA module for the sector and analyze the wave form for correctness. For information about the Tx
sample port, see Understanding the Power Amplifier module on page 18.
This procedure is complete.

5. Position the access panel and start all screws by hand.
Be sure to thread the rubber sealing washer on the screw shank before inserting it in the access panel
screw hole.
6. Use a torque wrench with a 5/32 inch tamper-resistant hex drive bit set to 18 inch-pounds to tighten all
screws evenly.
7. Re-seal the ground wires.
a. Examine the two ground wires that protrude through the side of the access panel.
Each ground wire has a rubber grommet and a 11/16 inch sealing net. The rubber grommets may be
in their proper location, tight against the access panel. Or, the rubber grommets may have been
pushed away from the access panel when the access panel was moved back into place.
b. For both ground wires, ensure the rubber grommet is pushed back snugly against the access panel.
c. Hand tighten the 11/16 inch nut, sealing the grommet in place.
d. Using the 11/16 inch open ended wrench, tighten the nuts on both grounding wires.
Wrench tighten snugly, but do not overtighten.
This procedure is complete.
WARNING
Screws should be started by hand. It is possible to damage the
thread in the cabinet if you use hand tool or a power tool.
Damaged threads must be repaired or the cabinet will be
improperly sealed and the IP-RN 8000 can be damaged. Use a
thread tapping set to fixed damaged threads.
WARNING
If access panels screws are not tightened with the correct torque,
electronic interface may occur causing equipment malfunction.
NOTE
Conduit must be installed to all openings on this access panel to
ensure equipment protection from the external environment. See
