Hot-swap drives
Your server contains hardware that lets you continue to operate your system while a
hard disk drive is removed or installed. These drives are known as hot-swappable
drives. They are also referred to as hot-swap drives.
Each hot-swap drive that you plan to install must have a hot-swap-drive tray
attached. The drive must have a single connector attachment (SCA) connector. Hot-
swap-drive trays come with the hot-swap drives.
• Your server supports six slim (1-inch) or three half-high (1.6-inch), 3.5-inch hot-
swap hard disk drives in the hot-swap bays.
• The hot-swap bays connect to a SCSI backplane. This backplane is the printed
circuit board behind the bay.
• 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.
• 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.
• The xSeries 150 server supports only one diskette drive.
• 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.
• Bays A and B come without a device 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.
• If you are installing a device with a 50-pin connector in one of the empty non-
hot-swap bays (bays A–B), you need a 68-pin to 50-pin converter. To order the
converter, contact your IBM reseller or IBM marketing representative.
