1-2 Preparation

The KFMSB-AA option is the DSSI adapter for DEC 7000 sysDEC
7000 tems. If an additional KFMSB adapter is required, you must also
order the CK-KFMSB-LB option. The CK-KFMSB-LB option includes the DSSI bulkhead cable assembly (17-03451-01) and four
terminators (12-31281-01).
The KFMSA-BA option is the DSSI adapter for VAX 7000 systems.
VAX
7000 If an additional KFMSA adapter is required, you must also order
the CK-KFMSA-LN option. The CK-KFMSA-LN option includes
the XMI-to-DSSI bulkhead cable assembly (70-27661-04) and four
terminators (12-31281-01).
DSSI devices and cables must be ordered separately. Table 1-1 lists the
storage devices, and Table 1-2 lists the cables.

Preparation 1-5

1.3 Check PIU Enclosure for Proper Airflow
When installing a BA654 PIU in the cabinet, make sure that the
rear panel arrow points toward the blower to permit proper airflow. See Figure 1-2.

Figure 1-2

PIU Rear Panel
Arrow should point toward blower.

BXB-0360B-92

1-6 Preparation

The arrow on the rear panel of the PIU enclosure must point toward the
blower. That is, the arrow must point up when installing the PIU below
the blower; it must point down when installing the PIU above the blower.
If necessary, use the following procedure to reinstall the PIU rear panel:
1.

Using a Phillips screwdriver, remove the 12 screws on the rear panel
(see 1 in Figure 1-3).

Remove and reposition the rear panel.

Install the 12 Phillips screws.

2-6 Installing the BA654 PIU Option

Figure 2-3 shows a DSSI PIU with three SBBs. Each SBB houses two
5.25" disks.
To install an SBB:
1.

Insert the SBB onto the shelf closest to the blower.

BXB-0045C-92

BA654 DSSI Disk PIU Configuration Rules
•

The DSSI disk PIU can occupy any quadrant in the cabinet.

•

In the system cabinet or in the bottom of the expander cabinet, SBBs
are installed starting closest to the blower and working down.

•

In the top of the expander cabinet, SBBs are installed starting closest
to the blower and working up.

•

The arrow on the rear panel of the PIU enclosure must point toward
the blower.

2-8 Installing the BA654 PIU Option

If only one SBB is present, attach a terminator (12-31281-01) to one
connector. Connect the DSSI cable to the other connector (see Figure
2-5).

If two or more SBBs are present, use jumper cables (BC21Q-01) to
daisy-chain the SBBs. Attach a terminator to the connector that is not
cabled (see Figure 2-5).

Installing the BA654 PIU Option 2-9

2.5 Cable the BA654 PIU and Set Node IDs
Connect the DSSI cable to the disk connector. Thread the cable
through the cable trough. Connect the other end of the cable to
the I/O bulkhead. See Figure 2-6. If necessary, set node IDs.

the cable opening.

Thread the cable through the cable trough at the side of the cabinet.

Connect the other end of the cable to the I/O bulkhead reserved for
DSSI I/O.

Setting Node IDs
The node IDs for KFMSA-BA modules are factory set with both ports having the node ID of 7. KFMSA-BA nodes IDs for single-host systems do not
have to be changed. For a dual-host system, the second host system’s
KFMSA-BA node ID must be set to 6. On a tri-host system, the third host
system’s KFMSA-BA node ID must be set to 5. On a quad-host system, the
fourth host system’s KFMSA-BA node ID must be set to 4. For more information, see the KFMSA Module Installation and User Manual.
If the second and third hosts have multi-host I/O panels (as shown in Figure 2-7), use the KFMSA-BA select knob to change the KFMSA-BA node
ID.
If required, set the DSSI node IDs for the integrated storage elements
(ISEs) using the switches on the DSSI disk PIU.

Acceptance and Troubleshooting 3-1

3.1 Restore Power and Check Self-Test Results
Power up the system and check the self-test display to see if the
KFMSx adapter passed self-test. You can also check the yellow
LED on the KFMSx adapter. The LED is on when the adapter
passes self-test. See Section 3.2 for more information on testing.
