18 Disassembly
9. Make sure that the pins on the bottom of the cover are in their holes and that the cover is flush against the subchassis.
10. Use the T15 driver and install the four screws (two on the front and two on the back) that attach the backplane cover to
the subchassis.
Assembling the Rear Subchassis
1. Slide the rear subchassis (MP4) under the sides of the chassis but don't push it all the way in yet; leave about two inches
of space.
2. Connect the keyboard cable (MP23) to the connector inside the subchassis.
3. Make sure that the on/off pushrod (MP13) and the chassis pins line up with the openings on the rear subchassis and
slide the subchassis into place.
4. Use the T15 driver and install the six screws (three on each side) that attach the rear subchassis to the chassis. Don't
tighten the screws until all six have been started.
5. Push the on/off pushrod (MP13) in from the front panel in until it snaps twice. The pushrod must snap twice to indicate
that it is firmly connected to the switch inside the subchassis .
Assembling the Keyboard Plug and Front Bezels
1. Use the T15 driver to install the two screws that attach the keyboard plug (A3) in the second and third hole on the
bottom right corner of the front frame (MP18) when viewed from the front. The bottom of the frame is thicker than the
top.
2. Align the pins on the top and bottom bezels (MP10, MP11) with the corresponding holes on the frame and snap the
bezels into place.
3. Check along the edges of the top and bottom bezels to make sure that they are snapped all the way into place.
4. Install the side bezels (MP 12) by inserting the top corner of each bezel first, then push the bottom corner toward the
side of the frame until it snaps into place.
Assembling the Front Frame
1. Position the front frame (MP18) close to the front of the chassis. Insert the on/off pushrod (MP13) into its opening and
connect the keyboard cable (MP23) to keyboard plug (A3).
2. Insert the sides of the chassis between the front frame (MP18) and the side bezels (MP12). Push the front frame onto
the chassis as far it will go.
3. Use the T15 driver and install the four screws that attach the front frame to the chassis.
4. Look through the slots in the bottom tray and check that the keyboard cable (MP23) is positioned in the cable clamp. If
not, insert the slot-head screwdriver through the slots in the bottom tray and slide the cable into the cable clamp. Don't
force the tiewrap under the cable clamp; position the tiewrap in
front of the cable clamp.
