Avoiding Connector and Backplane Damage During CRU/FRU Replacement

Symptoms of a Damaged Pin
Depending on which pin is damaged, the symptoms can include a down
link to a ServerNet/DA, a down disk-drive path (disk enable signal), or a
down processor. If a system is stable, a CRU/FRU should not
be removed to inspect the connectors unless either the CRU/FRU is being
replaced, symptoms have been encountered, or there is reason to believe
connector damage might have been propagated.
