Local Control Module Troubleshooting 
Introduction 
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. 
 
Green COND LED not Blinking 
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. 
 
Red STATUS LED Blinking Slowly 
If 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. 
Improper Configuration of the LCM 
An improperly configured LCM can be the cause of this indication.  Improperly 
configured, for example, can mean that the LCM's configuration does not match the 
actual receivers/transmitters mounted in the node.  This could happen if the LCM 
you are using was previously used in another node. 
Complete the following steps to troubleshoot. 
1  Verify the LCM configuration.  Refer to Configuring the LCM (on page 22) for 
instructions on properly configuring the LCM.
