Banks C, D, and E can accommodate six slim-high drives or three
half-high drives, or a combination of both drive sizes. If you use a
combination, remember that one half-high drive uses the equivalent space of
two slim-high drives.
- If you install drives in bank D or E, you must remove the
fan assembly on the rear of the server, install a
direct access storage device (DASD) backplane in
bank D or E, and install an optional 220-watt power supply.
For non-disk-array models, you might need to install an additional
SCSI-2 adapter.
- Each backplane has six connectors, to support up to six hard disk drives.
An address jumper is located on the rear of each backplane. You
must set the jumpers on these backplanes as described in
'Hot-Swap Backplane'
