To remove any HP NetRAID adapter and replace it with a new adapter, do the
following:
1. Turn off the system, unplug the power cord(s) from the system, open the
HP Netserver panel or remove the HP Netserver cover, and disconnect
the SCSI cables from the existing HP NetRAID adapter. Remove the
existing adapter, and place it on a grounding mat or other antistatic
surface. If you have removed any HP NetRAID adapter with a Battery
Backup Unit (BBU), disconnect the BBU by unplugging the connector
