Voltage Regulator Modules

This section explains how to remove and replace the voltage regulator modules (master
and slave), which are connected to the system board in the B2000 workstation.
Removing a Voltage Regulator Module
WARNING
To prevent injury, unplug the workstation's power cord from the
electrical outlet before removing the voltage regulator modules.
Perform the following steps to remove a voltage regulator module:
1. Open the left side panel of the workstation as shown in the section "Opening the Left
Side Panel."
2. Remove the four T-15 Torx screws from the rear of the chassis that hold the power
supply in place, as shown in Figure 4-47.

NOTE
The two voltage regulator modules are connected to the bottom of the system
board, behind the power supply. So, in the next step, you must move the
power supply to the right in order to access the voltage regulator modules.
Note that you do not need to disconnect the power supply's cables from the
system board, nor remove the power supply entirely from the workstation
chassis in order to access the voltage regulator modules.
3. Slide the power supply to the right, towards the front of the workstation, until the hook
on the bottom of the power supply disengages from the support strap in the chassis
floor. (You do not need to disconnect the power supply's power cables from the system
board, nor remove the power supply entirely from the workstation chassis.)
