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.
