Common Replacement Procedures
The following procedures are common to all CRU replacement procedures.
Note: The hotpluggable power supplies, blowers, and drives DO NOT require halting
Fibre Channel data transfers.
Replacing a pluggable I/O module, transceiver, or a cable always interrupts data
transfers on the Fibre Channel loop.
Review the controller documentation to determine if replacing an I/O module,
transceiver or cable requires removing power.
1. Always implement all the ESD protection procedures.
2. Remove the defective CRU from the enclosure.
3. Remove the replacement CRU from the static-free container. Check the label
to ensure that the CRU is a compatible replacement. See Figure 70.
4. Align the CRU with the enclosure guide slots.
5. Slide the CRU into the enclosure until the CRU is against the backplane
connector.
6. Fully seat the CRU in the enclosure and verify that the CRU is operating
properly.
7. Place the defective CRU in the static-free container for shipment.
