Local Control Module Troubleshooting

Introduction

The LCM indicates its status through the FAULT and STATUS LEDs on the front of
the module housing. More detailed status information can be obtained using the PC-
based GS7000 ViewPort software.
The following sections provide troubleshooting procedures based on the FAULT and
STATUS LED indications.
WARNING:
Model GS7000 Node or Hub Node forward segmentation is set at the factory
to match the installed Forward Configuration Module (FCM). A mismatch
between the forward segmentation and the FCM may cause isolation or loss of
service.

Green STATUS LED not Blinking

If the green STATUS LED is not blinking, complete the following steps to
troubleshoot.
1 Make sure the LCM is mating correctly with the connectors on the OIB in the
node. See Installing the SM/LCM (on page 12) for instructions on proper
installation.
2 If the STATUS LED is still not blinking, remove the LCM from the node and
examine the pins of the LCM connectors. If any are bent or broken, replace the
LCM.
3 If the STATUS LED is still not blinking, input power is not being supplied to the
LCM through the OIB. Check and replace the OIB if necessary. Refer to Model
GS7000 Optical Hub Installation and Configuration Guide, part number OL-29936-
01, or Model GS7000 GainMaker Scaleable 4-Port Node Installation and Operation
Guide, part number 78-4013584-01, for more information.

Red FAULT LED Blinking Slowly

If the FAULT LED is blinking slowly, there is at least one alarm condition. This
indication could be caused by:
Improper configuration of the LCM

Real operating condition problems

The following sections explain how to troubleshoot each of these possibilities.
