Internal Drive Bays (Non-Disk-Array Models)

Internal Drive Bays (Non-Disk-Array Models)

Internal Drive Bays (Non-Disk-Array Models)

Internal drives are installed in bays . The bays are numbered 1 through 9.

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 3.5-inch hard disk drives only. Some models are supplied with a hard disk drive preinstalled in bay 1.
Bays 2 and 3 are 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.
Bay 4 has a preinstalled SCSI CD-ROM drive.
Bays 5-9 are for 3.5-inch or 5.25-inch drives.
The system board supports a maximum of two diskette interface devices. You can install a second 3.5-inch diskette interface device in bay 2. Be sure the screw holes in the device line up with the screw holes in bay.
Bays 5-9 contain trays for housing 3.5-inch drives. If you want to install a 5.25-inch drive in one of these bays, you must remove screws and the tray before attempting to install the drive.
You can install a full-high drive between bays 6 and 7 by removing the trays from these bays. You cannot install full-high drives between bays 4 and 5, or between bays 8 and 9.
If you are installing one or two integrated drive electronics (IDE) drives, you must purchase an IDE cable, such as in the PC Server Cable Kit.
If you are connecting two hard disk drives to the IDE controller, you must reset the jumpers on one of the drives, as specified in the documentation supplied with the drive.
If a preinstalled hard disk drive was not supplied with the server and you plan to have more than four 8-bit internal SCSI drives (including the CD-ROM drive), you must use an optional 7-drop SCSI cable in place of the 4-drop SCSI cable supplied with the server.
To install 16-bit devices, you need a 16-bit cable (and a 16-bit to 8-bit SCSI Internal Converter if you want to connect the CD-ROM drive to the 16-bit cable). See 'Internal SCSI Drives (Type 8640)' for additional information.
The IBM 3.5-inch rewritable optical disc drive requires a special mounting bracket.

The following table shows the widths, types, and maximum heights for the drives that you can install in each bay.

Table 2 Maximum Allowable Drive Sizes (Non-Disk-Array Models)

Bay	Drive Width	Drive Type	Maximum Drive Height
1	3.5-inch	Hard disk	25.4 mm (1 inch), with a drive in bay 2 41.3 mm (1.6 inches), with no drive in bay 2
2, 3	3.5-inch	Diskette 1	25.4 mm (1 inch)
4	5.25-inch	CD-ROM	41.3 mm (1.6 inches)
5-9	3.5-inch or 5.25-inch	Hard disk, removable media 2	41.3 mm (1.6 inches)

NOTE:

Or a drive that connects to the diskette cable. Be sure the holes in the drive align with the drive housing.
Removable media include CDs, optical discs, and tapes.
