Adding a RemovableMedia Drive

Part Number: EK–PELAF–IC. B01

Introduction
The RX26 Drive
The RX26 is a 3 1/2-inch removable-media drive
packaged in its own mounting bracket. It can be fit
into a 5 1/4-inch drive bracket, making it easily
transferable from one system to another. The
RX26 drive can be used to back up system files,
load applications, and transport files between standalone systems.
Methods for Adding a Drive
There are two methods for adding a drive to your
system:
a. You can add the drive yourself
b. You can contract with your Digital service representative to add the drive.
If you choose to add the drive yourself, you should
allow about 15 minutes from start to finish.
In This Card

This card provides you with the necessary instructions for adding an RX26 removable-media drive to
your system. It also provides instructions for setting
the SCSI ID address on the drive.
Refer to the DEC 3000 Model 300 Series AXP
Hardware Reference Guide, part number
EK-PELCN-OG for additional information.

1. Preparing Your System
a. Back up your system files.
b. Shut down all software following the instructions in your software documentation.
c. At the console prompt (>>>), enter:
>>> show device

d. The following is an example screen display:
BOOTDEV ADDR DEVTYPE NUMBYTES RM/FX WP DEVNAM REV

0900

Record the SCSI ID address displayed in the
ADDR column:
(In the example,
A/3/0 indicates SCSI ID address 3.) You cannot set any other device to this address, nor can
you use SCSI ID 7, which is reserved for the
host controller.

g. At the console prompt (>>>), enter this command:
>>> set auto_action halt

h. Turn off (O) the monitor and all peripheral de
vices (printers, modems, expansion boxes).
i.

Turn off (O) the system unit.

Preparing Your System (cont)
WARNING: After you turn off the system unit
and before you unplug the power cord, wait about
one minute before opening the system unit. This
allows time for the power supply capacitors to
safely discharge.

Before opening the system unit:
•

Disconnect the monitor and system power
cords from the back of the system unit.

•

Disconnect the monitor video cable,
mouse/keyboard cable and any network cables.

•

Remove the monitor from the top of the system
so that you can remove the system unit cover.
(Two people are required to move the monitor.)

2. Opening the System Unit
a. Remove the two Phillips screws 1 on the right
and left back corners of the system unit cover.
b. Place the system unit so that the back of the
unit extends over the edge of your table or
desk.
c. Place your thumbs 2 on top of the two black
rubber caps on the back of the system unit, and
at the same time, place your fingers under the
cover’s bottom edge. Firmly push down with
your thumbs and, at the same time, pull up with
your fingers to lift off the cover.
d. Pivot the cover on the tabs that run along the
system unit’s front edge.
e. Pull the system unit cover up and away until it
releases from the tabs.
f.

Place the cover aside.

3. Attaching an Antistatic Wrist Strap
CAUTION: To avoid static discharge, do not
touch anything inside the system unit until you put
on the antistatic wrist strap that was shipped with
your system.
Follow the instructions on the envelope that contains the wrist strap. Store the strap after using it.

4. Setting a SCSI ID Address
Switches define the SCSI ID address for the RX26
removable-media drive. Your new RX26 drive
may be shipped by the factory with the switches
preset to a setting of 5.
You need to change a SCSI ID address only if that
address is already taken by another device. For example, the SCSI ID address for a new drive cannot
be set to the number recorded on panel 1, step f, because that address is already in use.
To set the SCSI ID address, choose an available ID
number (from 0 to 6), and refer to the next figure to
set the switches accordingly. Use a small pointed
instrument (such as a tip of a ballpoint pen) to
move the switches up or down. Do not use a pencil; graphite particles can damage the switches.

5. Removing Shield and Filler Panel
Remove the plastic filler panel and metal shield
from the front bezel on the system unit cover, as
follows.
a. Release the filler panel 1 from the metal
shield 2 by gently pressing on the filler panel
tabs 3 and pushing outward.
b. Store the shield and filler panel for future use.

6. Cabling the Drive
To cable a drive, follow these steps in succession:
a. Connect the large connector 1 on the power
cable to the power port on the back of the
RX26 drive.
b. Connect the small connector 2 on the power
cable to the smaller power port on the back of
the drive.
c. Connect the SCSI cable (key facing up) 3 to
the SCSI port on the back of the drive. The
power cable must be under the SCSI cable.
Tuck the SCSI terminator 4 (located at the end of
the SCSI cable) in the mounting bracket under the
RX26 drive.

7. Installing a Drive
Follow these steps to install an RX26 drive:
a. Insert the mounting bracket tabs into the slots
1 on the base of the system unit. The RX26
drive can only be installed in the location
shown.
b. Press down on the drive.
c. Lock the drive in place 2 .

8. Replacing the System Unit Cover
Check that the drive is locked in place and connected to the SCSI cable. If a drive is not properly
connected, your system will be unable to detect it.
To replace the cover, follow these steps:
a. Position the cover so that the lip on the front inside edge 1 fits over the four tabs 2 along
the front edge of the system unit.
b. Maintain a slight pressure on the front of the
cover 3 as you lower it. Make sure the sides
of the cover fit over the outside of the bottom
enclosure.
c. Press down firmly on the edges of the cover.
d. Replace the two screws that hold the system
unit cover in place 4 .

10. Restarting Your System
To verify that the installation of the new
removable-media drive was successful, enter the
following command:
>>> show device

Status information identifying the boot device,
SCSI ID address, device type, capacity of the drive
in megabytes, whether the device media is removable (RM) or fixed (FX), write-protect status (WP),
the device name, and the microcode revision number of the installed device is displayed. For example:
