Check if the management board gets loose. If so, install the management board again and
ensure that it is inserted into position, before you tighten the fastening screws. If the
management board still does not work, check if the connector of the slot on the backplane is
loose and check if the guide rail of the slot is deformed. If yes, insert the board to another
slot for a try. If the slot and connection are not the cause, return the management board for
repair.
When the Alarm LED is red, the cause may be the fault of another module in the system, in
which case you can check other modules (for example, linecard, fan, power, and
overheating) for any alarm. If yes, you should first handle the faults of other modules. You
can also identify the faults by logging in to the management software.
