Installing Internal Drives
Notes:
Banks C, D, and E support hot-swap drives only.
If your server is a disk-array model and you have drives
installed in banks C and D, and attached to the external
SCSI-2 connector, you must install an additional SCSI-2
adapter. If you have a non-disk-array model, you might
need to install an additional SCSI-2 adapter. (See
“Installing Adapters” on page 180 for instructions.)
You can install up to three half-high hot-swap drive IIIs
in each of banks C, D, and E.
In a disk-array model, banks C and D or D and E can be
daisy chained or linked together into a single SCSI-2 bus
using the “daisy chain option” cable. However, the SCSI
ID jumper (J12) on one backplane must be set to HI. (See
“Setting Backplane SCSI ID Jumpers (J12)” on page 252.)
After the backplane is completely installed, you do not
have to turn off the server to install hot-swap drives in
bank E. However, you must turn off the server when
performing the steps that involve installing or removing
adapters, backplanes, cables, and the fan assembly.
