N0060612N0060612
8 Disconnect the power supply cables from the I/O card, media bay backplane, and hard disk.
9 Unfasten the cable clamp that holds the power and IDE cables in place. The cable clamp is
located under the top cover of the platform base chassis.
10 Run all cables to the rear exterior of the main unit.
11 Remove the four power supply chassis screws from the rear of the main unit (see Figure 155).
Place the screws in a safe location.
Figure 155 Remove the BCM400 redundant power supply screws
12 Unfasten the exterior and interior power supply support bracket mounting screws (see Figure
143). Place the screws in a safe location.
13 Remove the redundant power supply cage and support bracket out and away from the
BCM400 main unit (see Figure 156). Place the power supply in a safe, clean, and static-free
location.
Warning: When the power is on, wait several seconds before removing the
power supply module completely from the power supply cage to ensure complete
electrical discharge.
Note: Remove the power supply carefully. Ensure the power supply cables are not
entangled or connected to any internal components.
