Basic Replacement Procedures - Compaq TA1000 Reference Manual

Basic Replacement Procedures

The following procedures apply to all CRU replacement procedures.
IMPORTANT: Always transport and store CRUs in a static-free container.
1. Remove the defective CRU from the enclosure.
2. Remove the replacement CRU from the static-free container. Check the
label to be sure that it is a compatible replacement (see Figure 7-1).
3. Align the CRU with the enclosure guide slots.
4. Slide the CRU into the enclosure until it is against the backplane
connector.
5. Fully seat the CRU in the enclosure and verify that it is operating
properly.
6. Place the defective CRU in the static-free container for shipment.
CAUTION: The hot-pluggable power supplies, blowers, EMU, and drives DO
NOT require halting all data transfers on the SCSI bus.
Replacing a pluggable I/O module or a SCSI cable always requires halting all
data transfers on the SCSI bus.
Some controllers may require removing power when replacing an I/O module or
SCSI cable.
CAUTION: To prevent ESD damage, never touch the CRU connector pins, leads,
or circuitry.
