Table 2-1 Workstation Disassembly

1. Remove/disengage any security devices that prohibit opening the workstation.

2. Disconnect the power cord from the electrical outlet and then from the workstation.

3. Disconnect all peripheral device cables from the workstation.

4. Remove the front bezel and top cover.

Press in on both release buttons found on the ends of the bezel and pull outward from the

workstation to remove it. Next, unscrew the captive screws and pull forward on the cover and

lift it off.

5. Disconnect all internal cables from System Board, Power Supply, and other components.

6. Remove the CD Drive.

Disconnect the CD drive control cable by pulling up on its pull tab and disconnect the power

cable by pressing in on its latch release

If the workstation has an audio card, disconnect the audio-extender cable and the CD drive

audio cable by pressing in on the audio-extender cable’s latch release. Lift up on the PCI cage

audio retainer tabs to remove the audio cable from the PCI cage.

Press in on the retainer clips on both sides of the CD drive bay and pull toward you.

8. Remove I/O cards. (The PCI card cage must first be removed from the system.)

Remove the PCI cage cover, and unscrew the I/O card’s bulkhead screw.

Grasp the I/O card’s bulkhead and the rear edge and lift it out of its PCI slot. As you lift

the I/O card, you may need to slightly rock it back and forth. This will loosen the I/O card from

its PCI slot

9. Remove the PCI backplane.

Unscrew the three T-15 Torx screws.

Slide the PCI backplane board away from the PCI cage’s I/O card openings and remove

it from the PCI cage. Note that the PCI backplane board has two elongated slots cut in it that

allow the card to slide in grooves located on the top of two PCI cage standoffs. The PCI

backplane board will stop sliding when it reaches the opposite end of the elongated slot. At

this point, the slot has been enlarged to allow you to lift the PCI backplane board out of the

PCI cage

11. Remove the power supply.

Disconnect the power supply cables from the system board by pressing in on the latch

releases on the connectors and pulling outward.

Unscrew the four power supply mounting screws located on the back of the system. Note that

there is a power supply support arm that fits into a slot on the system divider panel. This

support arm prevents the supply from falling onto the system board while you are unscrewing

the mounting screws.

Remove the AC power supply from the system by sliding the support arm out of its slot.
