6.Power down the switch. Open a Telnet session and enter the Shutdown command then disconnect the power cords from the power supplies.

7.Label and disconnect the Fibre Channel port cables. This will avoid compromising security and prevent data corruption when the switch is powered up with the new CPU module. Label I/O blades by slot number. I/O blade slots are numbered 1–4 and 6–9. Label Fibre Channel port cables by slot number and port number. Ports on each I/O blade are numbered 0–7 from top to bottom.

8.To unfasten the CPU module, disconnect the Ethernet and serial cables from the CPU module. Connect an ESD wrist strap to a ground point on the chassis or rack. Using a flat-bladed screwdriver, loosen the four captive screws at the top and bottom of the CPU module faceplate as shown in Figure 6-1. The bottom-left screw is under the latch.

CAUTION! The CPU module contains sensitive logic components. To avoid damage to the module, do not touch the CPU module components.
