Compaq ProLiant Storage System /U User Guide
I/O Board
The storage system must be powered down before the I/O board may be
replaced. This procedure is the same for all three I/O boards (Single Bus, Dual
Bus, or Recovery Server).
1. Perform a normal system shutdown.
2. Turn OFF the server(s) supporting the storage system, then place the
storage system in STANDBY (front panel power switch).
!
WARNING:
To avoid risk of injury from electrical shock, remove
all power cords to completely disconnect power from the system.
3. Remove the power cord(s) from the outlet and then from each
power supply.
4. Remove the SCSI cable(s) from the I/O board. In dual-bus and
Recovery Server systems, note the destination (Bus 1 or Bus 2) of
each cable.
5. Squeeze the latches and pivot open the two ejector levers securing the
I/O board in place.
