Internal drive bays
Internal drives are installed in bays.
• Your server comes with one CD-ROM drive and one 3.5-inch, 1.44 MB diskette
drive.
• The left front bays support 5.25-inch, half-high, removable-media drives. Any two
adjacent 5.25-inch, half-high bays can be converted to a single full-high bay.
Note: The server EMI integrity and cooling are both protected by having the left
front bays 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.
• You cannot install hard disk drives in the left front bays. You can install hot-swap
hard disk drives only in the hot-swap hard disk drive bays on the right front side
of the server.
• If you are installing a device with a 50-pin connector in one of the left front bays,
you will need a 68-to-50-pin converter (option number 32G3925).
• Your server supports 10 1-inch (26 mm) slim-high, 3.5-inch hot-swap hard disk
drives in the hot-swap bays.
• The hot-swap bays connect to the LVD SCSI backplane. Your server comes with
two SCSI channels on this backplane. For more information, see “Using the LVD
SCSI backplane” on page 53.
Some drives have a special interface called small computer system interface, or SCSI.
Using this interface, you can attach multiple drives to a single SCSI controller.
Notes:
1. Any information about SCSI drives also applies to other SCSI devices, such as
scanners and printers.
2. If you plan to install both internal and external SCSI devices, you must follow the
instructions in “Connecting external options” on page 79, in addition to the
instructions in this section.
An additional 16-bit, two-drop SCSI cable comes with your server for connecting
removable-media drives. This removable-media drive cable is located in the bottom of
your server between the open bays and the power supply area. It is folded and
restrained with a cable clamp.
If you want to install SCSI devices in the removable-media bays:
1. Locate the internal SCSI connector on the power backplane.
2. Use the 16-bit, two-drop SCSI cable located in the bottom of the server media bay.
3. Connect the SCSI device(s) in the removable-media bay to the internal SCSI
connector on the power backplane.
