Disks
Disks
The MicroVAX 3100 and VAXserver 3100 systems utilize the IndustryStandard Small Computer Systems Interface (SCSI) for connection of both
the internal and external disk storage devices. There are two separate
SCSI busses utilized within the MicroVAX 3100/VAXserver 3100 which
are depicted by the SCSI-A bus and the SCSI-B bus. The SCSI-A bus
provides two internal-only ports, while the SCSI-B bus provides one
internal port for the Model 10 system and three internal ports for the
Model 20 system. In addition, the SCSI-B bus provides a connection
for external expansion via the SCSI-B port connector on the rear of the
system unit.

SCSI Bus Configuration Rules
The Industry-Standard SCSI bus provides the following
guidelines:
•

A maximum of eight devices (IDs) per bus, including one used by the
controller, always ID # 6.

•

Total bus length not to exceed four meters, including both inside and
outside the enclosures.

•

The total number of boxes of any type connected to any single SCSI
bus shall not exceed four. This includes one host adapter and up to
three expansion boxes. There may be multiple devices (and therefore
IDs) in a single expansion box.

Disks Disk–1

System Configuration Rules
•

The Model 10 system has provisions for up to three internal, halfheight (3 1/2") devices.

•

The Model 20 system has provisions for up to five internal, half-height
(3 1/2") devices.
Refer to Figure Disk–1 for possible Device configuration of the
lower drive shelf device. Refer to Figure Disk–2 for possible device
configuration of the upper drive shelf (Model 20 only).

RX23–2 RX23 Disk Drive

Determining the Revision Level of the SCSI ROM
The RX23 diskette drive option is supported by systems which have a
SCSI ROM revision level V1.58 or higher. If the revision level of the SCSI
ROM is less than V1.58, the existing ROM must be replaced by the ROM
supplied with the RX23 installation kit.
Before you power down the system, determine the revision level of the
SCSI ROM as follows:
1. Press the halt button on the rear of the system unit to put the system
in console mode.
2. At the console prompt (>>>), enter T 50. The system configuration is
displayed.
3. Note the revision levels (Vx.xx) on the lines beginning SCSI-A and
SCSI-B.
If the revision level is V1.58 or greater, continue with the installation
procedure as described in Setting the SCSI ID of the RX23 Option. If
the revision level is less than V1.58, replace the ROM as described in
Replacing the SCSI ROM.

Replacing the SCSI ROM
Replace the SCSI ROM as follows:
1. Power down the system unit.
2. Disassemble the system to gain access to the System Module. Refer
to the FRU Removal and Replacement procedures for Model 10
and Model 20 systems in the MicroVAX 3100 and VAXserver 3100
Maintenance Guide (EK-A0372-MG.001).
3. Locate the SCSI ROM identified in Figure RX23–1.

RX23 Disk Drive RX23–3

Location of SCSI ROM on the System Module

4. Carefully remove the ROM from its retaining socket noting the
position of pin 1 identified by a notch on the chip.
CAUTION
Be careful not to bend the pins of the new ROM.
5. Install the ROM supplied with the same orientation as the ROM just
removed.
6. Reassemble the system.

Setting the SCSI ID of the RX23 Option
Before installation, you must assign a unique SCSI ID number to the
RX23 option. If you are unsure about the assignment of SCSI ID numbers
to devices, refer to the section entitled SCSI Bus Address ID Settings in
the MicroVAX 3100 and VAXserver 3100 Maintenance Guide.
NOTE
Perform a "SHOW DEVICE" command at the console prompt to
determine the available SCSI ID numbers. This must be done
to avoid SCSI ID address duplication. Refer to Appendix C for
examples of the "SHOW DEVICE" command.
If you are familiar with the assignment of SCSI IDs, you can set the
SCSI ID of the RX23 option using the switches on the FDI board.
Figure RX23–2 shows the location of the SCSI ID switches on the FDI
board and Table RX23–2 lists the possible SCSI ID switch settings.
