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.
