Replacing a Host or Device I/O SBB
CAUTION: When you remove an SBB, the airflow through the shelf is reduced.
Always install the replacement unit immediately to prevent overheating.
1. Ensure the SCSI bus connected to the SBB is quiescent (no I/O activity).
2. Disconnect the cables (or jumper) from the front panel of the SBB.
3. Release the SBB from the shelf slot by squeezing the mounting tabs on
the SBB together and pulling it forward until clear of the shelf
(Figure 3-16).
4. Insert an identical model SBB in the slot and push it in until an audible
click is heard indicating the SBB is fully seated (SBB front panel
mounting tabs expand and engage the shelf).
5. Observe that the SBB status LEDs are operating.
6. Reconnect the cables and jumper (which were disconnected from the
original module).
