Caution: Electrostatic discharge can damage sensitive components. Use appropriate
antistatic precautions before handling any components.
1. Unpack the new fan/communications canister.
Caution: Bending or damaging Fibre Channel cables can result in degraded
performance or data loss. Fibre Channel cables are fragile and can break easily.
Handle the cables carefully. Do not pinch them with tie wraps, step on them, or bend
them at sharp angles.
2. Remove or open the rear access panel on the rack.
Important: If you are using a diagnostic program, stop the program before
disconnecting the cables. Label the cable that is connected to the failed controller.
3. Disconnect all interface cables (RS-232 and Ethernet) from the failed
fan/communications canister (Figure 4-9).
