AT&T Alcatel-Lucent 9363 Metro Cell - Troubleshooting Guide

Appendix D: Troubleshooting guide
If you are not able to make a voice call or use data
applications, follow the troubleshooting steps in this
appendix.
If you have multiple small cells at the same site and are
experiencing poor voice quality, slow data speeds, or
dropped calls, the cause may be interference between
the cells. It may be necessary to increase the separation
between cells or otherwise shield the cells from each other.
Preliminary steps
• Power down the MetroCell and wait 10 minutes.
• Power up the MetroCell and wait at least 15 minutes.
• Ensure that an appropriate (3G-capable) mobile
device is available.
• If the MetroCell has been configured to operate in
“Closed” mode, ensure that any device being used to
make test calls is on the Approved User List (see the AT&T
MetroCell User Guide available at att.com/metrocell).
• Check that an Internet router is installed.
• Check that the Internet line is working properly.
• Ensure that access to the router and MetroCell
are available.
LAN configuration requirements
Verify that the LAN Configuration Requirements in
Appendix A are met. This may require adjustment of certain
router parameters.
Debug interface
A number of LEDs and a reset button are located behind the
removable cover for debugging purposes (see Figure 2).
LEDs provide status indication for:
• Power
• System
• Phone (Device)
• Second Ethernet port (not used in the typical installation)
• GPS
These LEDs can be used to help diagnose problems – see
the troubleshooting steps below. The LED for the second
Ethernet port simply indicates that that port is in use.
Steps to perform LED troubleshooting
Step 1 – MetroCell power LED
If Then
The Power LED on the
MetroCell is ON
Power is OK, skip to Step 2.
The Power LED on the
MetroCell is OFF
Check the source of power to the MetroCell, including:
• The outlet feeding the Power Injector.
• The power cable feeding the Power Injector.
• The Power and Ethernet lights on the Power Injector.
• The Ethernet cable from the Power Injector to the MetroCell.
(Make sure it is shielded CAT5e cable, installed as described, and not damaged.)
If all of the above appear to be in good working order, call the AT&T Product Management
Center at 877-996-7017 and enter the PIN ‘METRO’ (63876).
