hard disk drive.

Description
Physical
Description

The RZ24L-EF hard disk drive is a 3.5-inch high density drive
capable of storing 245 MB of (formatted) information. It is a
Winchester-type drive using a SCSI interface and is designed
for use on low-end desktop and workstation systems to provide
random access data storage capability.
The RZ24L-EF drive conforms to the common command set
(CCS). The medium contained within the drive is a non-removable
head/disk assembly. The entire drive assembly (HDA and module)
is considered one field replaceable unit (FRU).

Description

Software
Requirements

To operate the RZ24L-EF hard disk drive, software must be
installed on the disk. Use a diskette drive, tape drive, or CDROM
drive to load the software on the RZ24L-EF. The RZ24L-EF hard
disk drive is formatted (ready to receive information) when it is
shipped from the factory.

Configuration
Termination

The RZ24L-EF hard disk drive should not be terminated
internally. The SCSI bus must be terminated; therefore,
termination must occur within the host system or the expansion
boxes.
If your drive or drive module has the terminator resistor packs
already installed, then use needlenose pliers to remove the packs.
The terminator resistor packs are located just behind the SCSI
port connector.
Refer to the DECsystem 5100 Maintenance Guide, EK-422AA-MG
for procedures on the termination of the SCSI bus.

Assigning the
SCSI ID

Follow these guidelines for assigning the SCSI ID:
•

Assign the SCSI ID number for each drive using the ID select
jumper.

•

Be sure to assign a unique ID number to each SCSI device.

Shelf

To remove the lower drive shelf:
1. Providing an option is present (for example, DHT80),

disconnect the 100-way cable (P/N 17-02295-02) attached to
the option. Do not take the option completely off the shelf.
If the system does not have an option present, then it has a
blank cover plate. Loosen the captive screw on the blank cover
plate (P/N 74-41590-01) and remove the plate (Figure 1–5).

Caution

When removing the EMI shield, grab the middle of the
shield with both hands and gently pull forward. Removing
the shield in any other way could cause damage to the
shield.
2. Carefully remove the EMI shield (P/N 74-42127-01) that is

connected to the upper and lower shelves by carefully pulling
the shield forward towards the front of the enclosure, as
instructed in the Caution above.
Pulling forward releases the two tabs that hold the shield in
place. Once the tabs are released, the shield should come out
easily. Note the way in which it is mounted, because it will
need to be reinstalled the same way.
Note

Notice how the SCSI cable and power cables are routed
through the slots in the EMI shield to the devices mounted
on the lower drive shelf. These cables need to be routed
the same way for reassembly.

SCSI ID
Settings

The TLZ06-FG cartridge tape drive is set to a default SCSI ID of
5 before the devices leave the factory. Default settings should only
be changed when a TLZ06-FG cartridge tape drive is being added
to a host system that already has a TLZ06 installed.
Note

Each SCSI device must have its own SCSI ID.
The SCSI ID is set or changed by adding jumpers to, or
removing jumpers from, a connector at the rear of the tape drive.

3. Test the TLZ06-FG drive by invoking either the canned tape

test (CT) or the level 2 internal drive diagnostics (S2). The
following procedures and examples show how to use the two
test commands:
a. Load a write-enabled scratch tape into the TLZ06.

b. At the console prompt, enter SCSI, the test type (CT or

S2), and the SCSI ID number as shown in the following
examples:
>>SCSI CT 5
Are you ready?
Y/N? Y
- self test completed OK
>>SCSI S2 5
invoking self test 2 ...
If testing a tape drive, insert a scratch tape.
Are you ready?
Y/N? Y
- self test completed OK

Using the help screen provided, determine whether or not
your system ROM supports the CT or S2 test.
