Internal drive bay diagram for the PC Server 325
Resolving The Problem
Internal drives are installed in bays. The bays are numbered 1 through 7.

NOTE:
If you install a drive that uses removable media (diskette, optical disc, or tape), you might need to remove or change the cover plate.
- Bay 1 is for 5.25-inch devices only. Some models are supplied with a hard disk drive preinstalled in bay 7.
- Bay 2 has a preinstalled SCSI CD-ROM drive.
- Bay 3 is for 3.5-inch diskette interface devices, such as a diskette drive or tape backup unit that uses the diskette cable. All models are supplied with a diskette drive preinstalled in bay 3.
- Bays 4-7 are for 3.5-inch drives.
- A full-high drive occupies two bays between bay 3 and 7. If you are installing a removable media device in bays 3 through 7, you must remove the tray from the front of both bays.
- The PC Server 325 Type 8639 is shipped with a 7 drop, 16-bit SCSI cable.
To install an 8-bit device, you will need a 16-bit to 8-bit SCSI Internal Converter. See "SCSI Drives" for additional information.
- The IBM 3.5-inch rewritable optical disc drive requires a special mounting bracket.
The PC Server 325 Type 8639 is shipped with a CD-ROM drive installed in bay 2, and a diskette drive installed in bay 3. Some models come with a preinstalled hard disk drive.

- A 41.3 mm drive installed in bays 4 through 7 occupies two bays.
