Replacing the R12000class CPU Module
If you are instructed by your service provider to replace the R12000class CPU module,
you must follow these steps:
1. If you have not already done so, turn off the workstation, remove the power cable,
and remove the system module from the chassis. See “Removing the System
Module” in Chapter 2
2. Remove the plastic faceplate from the system module by using a Phillips
screwdriver to remove five screws on the rear and two screws on the underside, in
the locations shown (Figure 5-9). Keep the two screws from the underside separate.
When reinstalling the faceplate, you must use the same screws.
