faulty and needs to be replaced. When the hard-disk status light indicates a drive
fault, you can replace that hot-swap drive without turning off the server.
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.
Internal drive bays
Internal drives are installed in bays. Your server comes with a preinstalled diskette
drive and a preinstalled CD-ROM drive.

Empty 5.25-inch bays
• Your server comes with one 3.5-inch, 1.44 MB diskette drive and one IDE CD-
ROM drive.
• The empty bays below the diskette drive come without a device installed. You can
use these bays for 5.25-inch, half-high, removable-media drives, such as tape
backup drives. You also can combine these bays into a single, full-high bay and
install a digital linear tape (DLT) drive; or, you can install a 3-Pack Hard-Disk
Drive option, which converts these bays to three hot-swap drive bays.
• The xSeries 340 server supports only one diskette drive.
• If you are installing a device with a 50-pin connector in either bay A or B, you
need a 68-pin to 50-pin converter (option number 32G3925).
• Your server supports three slim-high (1-inch) hot-swap hard disk drives in the
hot-swap bays. If your server has the 3-Pack Bay option installed, it supports
three additional hot-swap hard disk drives.
• The hot-swap bays connect to a SCSI backplane. This backplane is a printed circuit
board behind the bay.
Note: The server's 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.
SCSI drives
Some drives have a special design called small computer system interface, or SCSI. This
design allows you to attach multiple drives to a single SCSI channel.
