Description

The RZ26/RZ35 disk drive is a high performance 3 5 inch SCSI
device. It has a formatted disk capacity of 1.05 GR:5352M bytes.
The RZ26/RZ35 disk drive stores data in fixed length blocks on

thin-flm rigid media disks. The storage medium in the disk drive
is fixed (not operator removable).

Information

In order to install the RZ26/RZ35 disk drive in a MicroVAX 3100
platform system, the Digital Services employee will need to order
the disk drive option, order number RZ26/RZ35-EK.

RZ26/RZ35 SCSI ID Information

Setting the
SCSI ID

In a MicroVAX 3100 platform system, each SCSI device must have

a unique SCSI ID number. When installing the RZ26/RZ35-EK
disk drive option, the SCSI ID raust be set to an ID that is not

used by any of the other SCSI devices in the system. See Table
2-3 in the KA45 CPU System Maintenance Manual or the KA47

CPU 8System Maintenance Manual for more information.

To set the SCSI 1D on the RZ26/RZ35-EK disk drive option, follow
these steps:
1.

Locace the SCSI ID jumper wires on the disk drive. See
Figure 1-1.

RZ24L-EH SCSI ID Information

Setting the
SCSI D

In a MicroVAX 3100 platform system, each SCSI device must have

a unique SCSI ID number. When installing the RZ24L-EH disk
drive option, the SCSI ID must be set to an 1D that is not being
used by any of the other SCSI devices in the system. See Table
