To remove any HP NetRAID Series 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 Series adapter. Remove
the existing adapter, and place it on a grounding mat or other antistatic
surface. If you have removed an HP NetRAID or HP NetRAID-3Si
adapter, disconnect the Battery Backup Unit by unplugging the connector
