Removable Media Drive Bays
The server contains four bays for removable media drives plus a factory-installed 3.5-inch diskette drive.
The following figure shows the location of the removable media drive bays.

Removable media
drive bays
On the left side of the system at the top, a built-in bay contains a 3.5-inch diskette drive that supports both
720 KB and 1.44 MB media.
Below the diskette drive, four 5.25-inch half-height bays are available for peripherals with removable
media (diskette, CD-ROM, tape cartridge). Any two adjacent 5.25-inch bays can be converted to a single
full-height bay. The 5.25-inch drives can be removed directly from the front of the chassis after the 5.25-
inch plastic frame is removed.
The front bezel is retained by snap features and is accessible when the side panel is removed. Cosmetic
filler panels and metal EMI shields are installed over all unused 5.25-inch bays.
CAUTION: Do not put hard drives in the 5.25-inch half-height bays due to the EMI generated by hard
drives and the increased susceptibility to electrostatic discharge.
