Replacing the hot-plug backplane
The six drive hot-plug backplane is at the back of the hot-plug drive cage.
The backplane supports as many as six hot-swappable LVD SCSI drives. The
backplane provides activity LEDs for each drive. If the backplane fails, you
must replace it.

To replace the hot-plug backplane:

1Turn off the system and disconnect the power cord and all external
peripheral devices.
2Open the case. (See “Opening the case” on page 23 and “Preventing static
electricity discharge” on page 22.)
3Disconnect all cables to the hot-plug backplane, noting the connectors
so you can reconnect them after replacing the backplane.
4Remove all hot-plug drives, being careful to note which drive was in
which slot.
5Loosen the two captive thumbscrews that secure the backplane in the
bracket.
