Problem Isolation
Diagnostics are used to isolate a problem to a particular module, and to a certain degree, to a particular element on that
module. This module diagnostic failure information can then be used by the ARRIS support team to identify the root cause
of the failure.
Module Replacement and Repair
Once a module is diagnosed as being faulty, it needs to be replaced and returned to ARRIS for repair. See also Diagnostic
Failure and Recovery (page 1029).
Caution: ARRIS provides no means for module repair in the field, and any user attempts to initiate a repair or alter a
module may result in the voiding of that module’s warranty.
Applicable Modules
The following modules can be diagnosed by the use of the diagnostic CLI command:
CAM
RCM
SCM
Diagnostic Rules
The following rules apply to running diagnostics on the C4/c CMTS modules:
Module level diagnostics should be performed whenever a module fails to boot up, crashes, generates a serious error
message, or is suspected of being faulty, or when it is requested by support personnel.
Diagnostics can be run only manually and only on modules that have been taken out of service and shut down, but are
still powered up.
