Hot-swap drives
Your server contains hardware that enables you to continue to operate your system
while a hard disk drive is removed or installed. These drives are known as
hot-swap drives.
Each hot-swap drive that you plan to install must have a hot-swap-drive tray
attached. Hot-swap-drive trays come with the hot-swap drives.
v
Your server supports six slim (1-inch) line, SCSI LVD, 3.5-inch hot-swap hard
disk drives in the hot-swap bays.
v
The hot-swap bays are connected to a SCSI
backplane
. This backplane is the
printed circuit board behind the bay.
v
The backplane controls the SCSI IDs for the hot-swap drives.
Non-hot-swap drives
Diskette drives, tape drives, and CD-ROM drives are non-hot-swap drives. To
remove or install a non-hot-swap drive, you must turn off the server first.
Non-hot-swap drives are installed in bays A, B, C, and D only.
v
Your server comes with a preinstalled 3.5-inch, 1.44 MB diskette drive in bay D
and a preinstalled IDE CD-ROM drive in bay C.
v
The xSeries 232 server supports only one diskette drive.
v
The diskette drive uses 1 MB and 2 MB diskettes. For optimum use, format
1 MB diskettes to 720 KB, and format 2 MB diskettes to 1.44 MB.
v
Bays A and B come without devices installed. These bays are for 5.25-inch,
half-high, removable-media drives, such as tape backup drives. You can combine
bays A and B into a single full-high bay.
v
If you are installing a SCSI device with a 50-pin connector in one of the empty
non-hot-swap bays (bays A and B), you need a 68-pin to 50-pin converter. To
order the converter, contact your IBM reseller or IBM marketing representative.
Note:
The server electromagnetic interference (EMI) integrity and cooling are both
protected by having bays A and B covered or occupied. When you install a
drive, save the filler panel from the bay, in case you later remove the drive
and do not replace it with another.
