Overview
Overview
This manual contains descriptions of options that the MicroVAX 3100 Model
85/90/95/96 BA42B-based systems support. It provides instructions that
describe how to install each option into a MicroVAX 3100 Model 85/90/95/96
system. If there is option model-specific information, it is also described. The
option information is listed in alphabetical order. There is one section for each
option. Each section contains information under the following headings:
• Description — This subsection briefly describes the option.
• Ordering information — This subsection gives the order numbers for each
option’s field installable variant.
• Option contents — This subsection lists the option components.
• SCSI ID information — This subsection describes how to set the ID of a
SCSI device option. You must set the ID of all Small Computer System
Interface (SCSI) device options. Each SCSI device must have a unique
SCSI ID. The following table lists the recommended SCSI IDs for the
various SCSI devices that the MicroVAX 3100 Model 85, 90, 95, 96 systems
support.
SCSI ID Device
0 RZx1
1 RZx1
2 RZx1
3 RZx1
4 RRDx2
5 TLx, TZx, or RXx3
6 SCSI controller (internal default)
7 RZx or TZKx4
1These devices can be RZ25L, RZ25M, RZ26, RZ26L, or RZ28 disk drives.
2This device can be an RRD42, or RRD43 CD-ROM drive.
3This device can be an RX23 or RX26 floppy disk drive or TLZ06, TLZ07, TZ30, TZK10, or
TZK11 tape drive.
4These devices can be RZ25L, RZ25M, RZ26, RZ26L or RZ28 disk drives, or TZK10 or TZK11
tape drives.
• Installation — This subsection provides instructions that describe
how to install the option into a MicroVAX 3100 platform system. Any
model-specific information is also described in this subsection.

1.2 Removing the Drive-Mounting Shelves
Unless you need to access the drives on the lower drive-mounting shelf, it is not
necessary to separate the upper shelf from the lower shelf; use these steps to remove
the drive-mounting shelves as a single unit.
1. Unfasten the upper and lower drive-mounting shelves together as a single
unit (Figure 1–3).
a. Unscrew the lower three captive screws from the from the shelves,
leaving the topmost captive screw for support.
b. Loosen the two panhead screws so that the shelves can slide out; it is
not necessary to remove them.
c. Loosen the topmost captive screw.
