Troubleshooting: CSM Check-list
Problem Description
Many of the Clock Synchronization Manager (CSM) board failures may
be resolved in the field before sending the boards to the factory for
repair. This section describes known CSM problems identified in field
returns, some of which are field-repairable. Check these problems before
returning suspect CSM boards.
Intermittent 19.6608 MHz Reference Clock/GPS Receiver Operation
If having any problems with CSM board kit numbers, SGLN1145 or
SGLN4132, check the suffix with the kit number. If the kit has version
“AB”, then replace with version “BC” or higher, and return model “AB”
to the repair center.
No GPS Reference Source
Check the CSM boards for proper hardware configuration. CSM kit
SGLN1145, in Slot l, has an on-board GPS receiver; while kit
SGLN4132, in Slot 2, does not have a GPS receiver. Any incorrectly
configured board must be returned to the repair center. Do not attempt to
change hardware configuration in the field. Also, verify the GPS
antenna is not damaged and is installed per recommended guidelines.
Checksum Failure
The CSM could have corrupted data in its firmware resulting in a
non-executable code. The problem is usually caused by either electrical
disturbance or interruption of data during a download. Attempt another
download with no interruptions in the data transfer. Return the CSM
board back to the repair center if the attempt to reload fails.
GPS Bad RX Message Type
This problem is believed to be caused by a later version of CSM
software (3.5 or higher) being downloaded, via LMF, followed by an
earlier version of CSM software (3.4 or lower), being downloaded from
the CBSC. Download again with CSM software code 3.5 or higher.
Return the CSM board back to the repair center if the attempt to reload
fails.
CSM Reference Source Configuration Error
This problem is caused by incorrect reference source configuration
performed in the field by software download. CSM kits SGLN1145 and
SGLN4132 must have proper reference sources configured (as shown
below) to function correctly.
