Redundancy Module Faults

Redundancy module faults appear in the following locations:
  • On the module status display
    For fault messages that appear on the module status display, see 1756-RM3 Status Indicators.
  • In the Status area on the Module Info tab of the RMCT

Fault Log Parameters
Parameter
Description
Event No.
A unique, sequential number to identify the fault.
Time Stamp
The date and time that the fault was logged.
Severity
One of the following fault severity types:
  • Minor recoverable—The fault does not stop redundancy operation and provides you with a recovery mechanism.
  • Minor nonrecoverable—The fault does not stop redundancy operation. No recovery mechanism is available.
  • Major recoverable—The fault impacts redundancy operations, although the effect is not always immediate. For example, if the fault occurred in the secondary redundancy module, the secondary chassis is disqualified and is not able to take control if the primary redundancy module fails.
  • Major nonrecoverable—The fault is critical and redundancy operations stop:
    • A switchover can occur.
    • No recovery mechanism is available.
    • The module can require replacement.
Code
The cause of the fault. Depending on the fault, the resolution may also be identified. Example causes of a fault include the following:
  • CPU temperature is too high
  • Memory card failure
  • No SFP transceiver is installed on Link 1 or 2
  • Module in chassis failed; replace module
Status
One of the following fault statuses:
  • Reported
  • Cleared
