Upgrades 5-11

WARNING: To avoid possible electrical shock, the server’s power cord must be disconnected from the power source before accessing its internal components.

You need a #1 and a #2 Phillips screwdriver. A pair of needlenose pliers is also helpful for removing and replacing screws. Follow this procedure:

1Make sure server power is off and the power cord is unplugged.

2Remove the cover, as described in “Removing the Cover” on page 5-6.

3Perform the steps illustrated in Figure 5-7.

a Disconnect the cable bundle that connects the power supply to the motherboard (step 1 in Figure 5-7).

b For Model CS/2600 only, disconnect the cable attached to the rear of the daughtercard mounted on top of the disk drive bracket. Pull it toward you to expose the mounting screw that fastens the power supply module to the bottom of the chassis (step 2 in Figure 5-7).

c Remove the mounting screw (step 3 in Figure 5-7).

dSlide the power supply module toward the front of the server and lift it out (step 4 in Figure 5-7).

The bottom of the power supply has two keyhole slots that fit over standoffs located on the bottom of the chassis. You must slide the power supply far enough forward to lift it off the standoffs.

eFor Model CS/2600 only, remove the power wiring harness from the connector on the rear of the diskette drive (step 5 in Figure 5-7).
