6.3 SCSI ID Information
In a VAX 4000 BA42B-based system, each SCSI device must have a unique
SCSI ID number. In an RRD43 CD–ROM drive, the SCSI ID number is
determined by three jumpers (See Figure 6–2). When installing an RRD43
CD–ROM drive in a system, set the SCSI ID jumpers to a value that is
not used by any of the other SCSI devices in the system. See your system
documentation for more information about the SCSI bus.
The following procedure describes how to set the SCSI ID number on an
RRD43-EK CD–ROM drive option.
1. Determine the SCSI ID number to be assigned to the RRD43 CD–ROM
drive option. Typically, the RRD43 CD–ROM uses SCSI ID 4; however, the
system manager may prefer to make this decision.

2. At the console prompt on the system console terminal, enter the SHOW
DEVICE command. This will list the SCSI ID numbers for the existing
devices in the system. Verify that you are using a number that is not
currently assigned to another device.
3. Locate the SCSI ID jumper pins on the CD–ROM drive. See Figure 6–2.
4. Position the jumpers for the SCSI ID number selected. Table 6–1 shows
the jumper settings for each SCSI ID.

9.3 SCSI ID Information
In a VAX 4000 BA42B-based system, each SCSI device must have a unique
SCSI ID number. When you are adding a SCSI device to an existing system,
you must set the SCSI ID of that device to an ID that is not used by any other
SCSI device in the system. (Refer to the VAX 4000 Model 100, 100A, 105A
KA52/53 CPU System Maintenance manual.)
To set the SCSI ID of the TZ30-EL option:
1. Locate the SCSI ID switches on the right side of the TZ30-EL option (see
Figure 9–2).
2. Determine the SCSI ID number that you want to assign to the TZ30-EL
option.
Note
When the system is in console mode, you can use the command SHOW
CONFIG to view the SCSI ID numbers used by existing devices in the
system.
