3.5-Inch RF-Series Disk Drive Options

3.5-Inch RF-Series Disk Drive Options
Description

The 3.5-inch RF-series disk drives are high-performance DSSI
devices which store data in fixed length blocks on thin-film rigid
media disks. The storage medium in the disk drive is fixed, not
operator removable.

Ordering
Information

To receive the appropriate installation hardware when installing
a 3.5-inch RF-series disk drive in a BA42B-based VAX 4000
system, a Digital Services employee must order the disk drive
option rather than the basic disk drive alone.

Option
Contents

The 3.5-inch RF-series options contain the disk drives as well as
a mounting bracket (P/N 74–44226–01), and the four grommets
(P/N 12–31734–01).

Installation
3.5-Inch RF-Series DSSI IDs
Setting the
DSSI ID

In a BA42B-based VAX 4000 system, each DSSI device must
have a unique DSSI ID number. When installing 3.5-inch RFseries disk drive options, the DSSI ID must be set to an ID that
is not used by any of the other DSSI devices in the system. For
further information see the appropriate documentation for the
particular system with which you are working.
To set the DSSI ID on 3.5-inch RF-series disk drive options,
follow these steps:
1. Locate the DSSI ID jumper wires on the disk drive. See
Figure 2–1.

Note
When the system is in console mode, enter the SHOW
DSSI command to view the DSSI ID numbers for the
existing devices in the system.

3. Position the jumpers for the DSSI ID number selected.
Table 2–1 shows the DSSI ID number and the corresponding
jumper wire combinations.

3.5-Inch RF-Series Installation Procedures
Before
Installing
3.5-Inch
RF-Series Disk
Drive Options

Before installing the 3.5-inch RF-series disk drive option on
the upper shelf, remove the enclosure cover. See the BA42B
Enclosure Maintenance Manual (EK–472Ax–MG) for more
information. The 3.5-inch RF-series disk drive options can only
be installed on the upper drive-mounting shelf of a BA42B-based
VAX 4000 system.

Installing
3.5-Inch
RF-Series Disk
Drive Options

To install 3.5-inch RF-series disk drive options, follow these
steps:
1. Attach the mounting bracket (P/N 74–44226–01) with the
four grommets/screws (P/N 12-31734-01). The grommets
fit into the recessed side of the imprinted pockets on the
bracket. Figure 2–2 shows a sample 3.5-inch RF-series
disk drive option with the mounting bracket. If you receive
the drive with the mounting hardware already attached,
disregard this step.

2. Identify the drive-mounting shelf position where the 3.5-inch
RF-series option is to be installed. See the BA42B Enclosure
Maintenance Manual (EK–472Ax–MG) for information about
mass storage device orientation and combinations.

3.5-Inch RF-Series Installation Procedures

3. Identify the power cable that provides power to the drivemounting shelf where the 3.5-inch RF-series option is to be
installed. Connect the power cable to the power connector on
the back of the 3.5-inch RF-series disk drive option.
4. Connect a DSSI cable connector to the back of the 3.5-inch
RF-series disk drive option.
5. Identify the spring clip for the drive position where the
3.5-inch RF-series disk drive option will be installed
(Figure 2–3). Then remove the lock-out screw if it has not
already been removed.
Figure 2–3 shows how to install sample 3.5-inch RF-series
disk drive options.

3.5-Inch RF-Series Installation Procedures

7. Push the 3.5-inch RF-series disk drive option in until the
grommets are secure in the cutouts, then slide the drive
away from the spring clip on the drive-mounting shelf so that
the clip locks the disk drive into position.
After the 3.5-inch RF-series disk drive option is installed, replace
the enclosure cover.

Diagnostics
Diagnostic
Support

The BA42B-based VAX 4000 system provides diagnostic support
that tests the operation of a 3.5-inch RF-series disk drive.
Enter the following command at the console prompt to verify
that the 3.5-inch RF-series disk drive is visible on the bus:
>>> SHOW DSSI
If the test fails, the console terminal displays a hard error
message containing test mnemonic (DSSI).
For details on diagnostics, refer to the appropriate
documentation for the particular system with which you are
working.
