DEC 3000 Model
300 Series AXP

Adding an Internal
Fixed Disk Drive

Part Number: EK–PELAD–IC. B01

Introduction
Possible Configurations
Your DEC 3000 Model 300 series AXP system is
configured with a fixed disk drive at the factory in
one of the following ways:
a. With one RZ25 (425-megabyte) drive
b. With one RZ25L (535-megabyte) drive
c. With one RZ26 (1050-megabyte) drive
d. With one RZ26L (1.05-gigabyte) drive
e. With two fixed disk drives (any combination of
the above drives)
f.

With no disk

You can add an optional RZ28 (2.1-gigabyte) fixed
disk drive at a later date.

Methods for Adding Storage
There are two methods of adding storage to your
system:
a. You can add drives yourself
b. You can contract with your Digital service representative to add the drives
If you choose to add a drive yourself, you should
allow about 15 minutes from start to finish.

In This Card
This card provides you with the necessary installation instructions for adding a fixed disk drive to
your system. It also provides instructions for setting a SCSI ID address on the drive.
Refer to the DEC 3000 Model 300 Series Hardware
Reference Guide, 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 this command:
>>> show device

d. The following is an example of the resulting
screen display

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.

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 the 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
unit 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 top 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 press down with
your thumbs and, at the same time, pull up with
your fingers to lift 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. Locating the Drive Positions
You can exchange the drives already installed in
position 1 or 2 for a new drive. Up to two RZ25,
RZ25L, RZ26, RZ26L or RZ28 fixed disk drives
can be installed in your system.

5. Setting a SCSI ID Address
Jumpers define the SCSI ID address for a SCSI
drive. Your new drive may be shipped from the
factory with jumpers in all positions; this helps
prevent loss of the tiny jumpers during shipment.
Save any jumpers you remove.
You need to change a SCSI ID address only if that
setting is already taken by another device. For example, you cannot set the SCSI ID address of a new
drive 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, refer to the following figures, and carefully remove or attach jumpers as needed. Use
tweezers or another small tool to remove jumpers.
The RZ25 jumper settings are as follows:

Jumper
Setting

SCSI ID: 0

SCSI ID: 4

MLO-010248

5. Setting a SCSI ID Address (cont)
Your may need to remove the bracket attached to
an RZ25L disk drive. See your DEC 3000 Model
300 AXP Series Hardware Reference Guide, part
number EK-PELCN-OG, for instructions. The
RZ25L jumper settings are as follows:

Jumper
Setting

SCSI ID: 0

SCSI ID: 4

MLO-011295

Note: Jumpers may contain 6 or 8 pins depending
on the manufacturer’s design.

5. Setting a SCSI ID Address (cont)
The RZ26 jumper settings are as follows:

Jumper
Setting

SCSI ID: 0

SCSI ID: 4

MLO-010699

Note: Jumpers may contain 6 or 8 pins depending
on the manufacturer’s design.

5. Setting a SCSI ID Address (cont)
The RZ26L jumper settings are as follows:

Jumper
Setting

SCSI ID: 0

SCSI ID: 4

MLO-011296

Note: Jumpers may contain 6 or 8 pins depending
on the manufacturer’s design.

5. Setting a SCSI ID Address (cont)
The RZ28 jumper settings are as follows:

Jumper
Setting

SCSI ID: 0

SCSI ID: 4

6. Removing a Drive
If you wish to exchange an existing drive for a new
fixed disk drive with greater storage capacity, remove the old drive as follows:
a. Unlock the disk drive.
b. Disconnect the internal power and SCSI interface cables from the back of the drive.
c. Tilt the drive to the left and lift it out of the
system.
d. Remove the mounting bracket from the drive
only if it is needed for the new drive.
If you are removing an RX26 removable-media
drive and wish to install an RZxx fixed disk drive in
its place, refer to your DEC 3000 Model 300 Series
AXP Hardware Reference Guide for instructions.

7. Cabling a Drive for Position 1
To cable the new drive for installation in position 1,
follow these steps in succession:
a. Connect the large power connector 1 on the
power cable to the power port on the back of
the RZxx drive.
b. Connect the SCSI cable 2 (key facing up) to
the back of the fixed disk drive. The power cable 3 must be under the SCSI cable.
c. Lay the SCSI terminator (located at the end of
the SCSI cable) and the remaining length of
power cable in the empty position 2.

8. Cabling a Drive for Position 2
To cable the new drive for installation in position 2,
follow these steps in succession:
a. Connect the large power connector 1 to the
power port on the back of the RZxx drive.
b. Connect the SCSI cable 2 (key facing up) to
the back of the fixed disk drive.
c. Tuck the SCSI terminator 3 (located at the
end of the SCSI cable) in the mounting bracket
under the RZxx drive.

9. Installing a Drive
Follow these steps to install an RZxx drive:
a. Insert the mounting bracket tabs into the slots
1 on the base of the system unit.
b. Press down on the drive.
c. Lock the drive in place 2 .

10. 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 .
