Front Service Position
CAUTION:
The stabilizer must be firmly attached to the bottom front of the rack to prevent
the rack from turning over when the drawers are pulled out of the rack. Do not
pull out or install any drawer or feature if the stabilizer is not attached to the
rack.
Note: Some operations in this procedure may require a step stool, depending on
the height of the individual. Either of the following may be used:
P/N 46G5947
Six foot step ladder
P/N 93G1147
Step stool
To put the drawer in the front service position, follow these steps:
1. Do the steps in the power off procedure as detailed in "Stopping the System
Unit" in chapter 2 of
RS/6000 Enterprise Server Model H Series User's Guide.
2. If the rack has a rear door, open it.
3. Note the locations of the following; then disconnect them from the back of the
CPU Drawer:
Power cords
Display cable
Keyboard cable
Any other cables and cords
4. Remove the screws that attach the drawer to the rear of the rails in the rack.
5. If the rack has a front door, open it.
6. Remove the screws that attach the front bezel to the rack.
7. Pull the drawer out until it is stopped by a detent on the top of the drawer. The
drawer will come out approximately 12 inches. The drawer may tilt downward
slightly while in the front service position.
8. Remove the screws from the top center of the drawer and slide the cover to the
left and lift the front access cover up.
9. Loosen the retained screws and lift the top air baffle from the drawer.
10. If you have a Model H50, remove the I/O air duct, which is held in place with
velcro, from the plenum area. Place the duct in a safe location to prevent
damage.
11. If you have a Model H70, remove the foam block at the center of the air duct.
Keep the foam block for replacement.
