Installing Optional Internal Storage Devices; Installing Hard Disk Drives In The Lower Right Side Inner Bay - Digital Equipment AlphaStation 500 Series User Information

Installing Optional Internal Storage Devices

This section tells you how to install optional hard drives into the two removable drive tray
brackets that are located in the internal mass storage bays (right & left). The SCSI hard
disk drives, CD-ROM, and floppy drives are all mounted on removable drive tray brackets.
To install an internal storage device, follow this procedure:
1. Turn off your system and unplug the power cord from the wall outlet.
2. Unlock and remove the top cover, as described earlier in this chapter.

Installing Hard Disk Drives in the Lower Right Side Inner Bay

The lower right side drive bay (below the CD-ROM), contains a drive tray that
accommodates up to two hard drives: either one 3.5 inch x 1.0 inch hard disk, or one 3.5
inch x 1.6 inch hard disk, or two 3.5 inch x 1.0 inch hard disks. Due to thermal
considerations, you cannot install a 3.5 inch x 1.6 inch hard disk and a 3.5 inch x 1.0 inch
hard disk simultaneously in this bay. Follow these procedures:
1. Set the SCSI drive device jumpers or switches for the desired SCSI ID (address). This
address depends on the unit numbers currently in use. (See Appendix D, Device
Mapping, for a list of typical SCSI ID assignments. Appendix H, Equipment Log,
contains space to record your systems SCSI ID assignments.) Follow the guidelines in
the manual that came with the drive.
_________________________ NOTES ____________________________
•
The CD-ROM is always installed in the top right side slot.
•
The CD-ROM and optional tape drives are narrow SCSI devices. You must
use a wide-to-narrow SCSI adapters with it. One adapter (part number 17-
04009-01) is supplied with the system.
•
If you are using Wide SCSI drives, you do not need the adapter.
