Termination power is typically supplied by the SCSI adapter card, in addition to being supplied as the default configuration by the internal drives and the controller.
Termination power can be disabled by removing jumper J4 on the controller (see below Figure 6).
(For information on accessing the controller to remove the jumper, see 'Removing and Replacing the Controller'.)
Drive termination power can also be disabled by removing jumpers on the drives.
