Chapter 7
Adding or Replacing Internal
Mass–Storage Devices
This chapter describes how to install new mass-storage drive options such as
Winchester disks, tape drives, diskette drives, or CDĆROM drives inside your
AViiON 530 or 4600 computer unit. It also provides directions for replacing failed
internal mass-storage devices. For information on installing external devices to your
system, refer to the documentation that accompanied the external subsystem or
independent device.
To install or replace a drive, you will need device-specific information not provided in
this manual. Make certain you have the appropriate documentation to set jumpers
and operating parameters on each individual drive you need to configure or
reconfigure.
Guide to AViiON  and DG/UX  System Documentation lists the
manuals that support the mass storage devices available in AViiON 530 and 4600
series systems.
NOTE: Before you add or replace any mass storage device, refer to Chapter 4,
Setting Up and Installing a SCSI Bus," and Chapter 6, Expanding and
Maintaining Your Computer System," to plan or verify your configuration.
Supported Mass–Storage Devices
An integrated Small Computer Systems Interface (SCSI) bus controller supports all
the mass-storage devices housed inside your computer unit. Each SCSI controller in
your system can support up to seven devices or adapters, but a maximum of four
devices will fit inside an AViiON 530 or 4600 series computer unit chassis. Since tape,
diskette, and CDĆROM drives require access from the front, only two of the internal
drives can use removable media. Disk drives can occupy all four internal
mass-storage spaces.
Table 7Ć1 lists the internal mass-storage devices supported by AViiON 530 and 4600
series systems.
