Card Absent A/B
If the MC module is physically missing, check if the reported missing MC was
removed. If not, replace the reported MC.
Communication loss
A loss of communication may be reported in the following cases:
•
A new main card module is inserted and not yet initialized.
•
Reset to other card or a Configuration Update to the Other Card command
was executed.
•
A problem in the communication between the two main modules has
occurred.
If none of the above are the cause of the communication loss, try resetting the
Standby MC.
³
To reset the Standby MC:
1.
Go to Configuration>System>Protection>Main card redundancy.
2.
Reset the other card.
If the error persists, replace the MC in question.
Hardware mismatch
In cases in which the two main modules do not have the same hardware version,
replace the main module so that the HW versions are compatible.
Software mismatch
In cases in which the two main modules do not have the same software version,
update the software as explained below.
³
To update the software version:
1.
Go to Configuration>System>Protection>Main card redundancy.
