Copper Pass-thru Module (CPM) may not power up on insertion - IBM BladeCenter

Troubleshooting


Problem

The Copper Pass-thru Module (CPM) BladeCenter switch module occasionally does not power up on insertion. In about 1 in 50 inserts, the switch module will not automatically power up. The problem is specific to a human event driven insertion (it does not occur on power cycle) and it is easily recovered. Recovery is possible by either reinserting the module or by cycling power on the chassis.

Symptom
The Copper Pass-thru Module (CPM) BladeCenter switch module occasionally does not power up on insertion. In about 1 in 50 inserts, the switch module will not automatically power up. The problem is specific to a human event driven insertion (it does not occur on power cycle) and it is easily recovered. Recovery is possible by either reinserting the module or by cycling power on the chassis.

Affected configurations
The system may be any of the following IBM BladeCenter:  
  • IBM BladeCenter, type 8677, any model
