The LCM indicates its status through the STATUS and COND LEDs on the front of 
the module housing.  More detailed status information can be obtained using the 
handheld programming terminal. 

The following sections provide troubleshooting procedures based on the STATUS 
and COND LED indications. 

 

  

WARNING: 

the installed Forward Configuration Module (FCM).  A mismatch between the 
forward segmentation and the FCM may cause isolation or loss of service. 

 

 

If the green COND LED is not blinking, complete the following steps to 
troubleshoot. 
1  Make sure the LCM is mating correctly with the connectors on the optical 

interface board (OIB) in the node.  See Installing the SM/LCM (on page 12) for 
instructions on proper installation. 

2  If the COND LED is still not blinking, remove the LCM from the node and 

examine the pins of LCM connectors.  If any are bent or broken, replace the LCM. 

3  If the COND 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 GainMaker Scaleable 4-Port Node Installation and Operation Guide, part 
number 4013584 for more information. 

 

If the STATUS 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.
