Figure 4-49. Master and Slave Voltage Regulator Modules
Perform the following steps to replace a voltage regulator module:
1. Press down on the ejector tabs on either side of the system board connector to open
them. Be sure that you will be inserting the voltage regulator module into the correct
system board connector (the top connector if it is a master voltage regulator module, or
the bottom connector nearest the chassis floor if it is a slave).
2. Orient the notch on the gold edge of the voltage regulator module so that it aligns with
the notch-key in the system board connector. Push the voltage regulator module into the
correct system board connector (the top connector if it is a master voltage regulator
module, or the bottom connector nearest the chassis floor if it is a slave) until the
voltage regulator module is seated entirely in the connector.
NOTE
The ejector tabs will return to the locked position when the voltage regulator
module is fully seated in the connector.
3. Slide the power supply towards the rear of the workstation. You must engage the hook
on the bottom of the power supply into the support strap in the chassis floor.
4. Screw in the four T-15 Torx screws that hold the power supply in place into the rear of
the chassis. See Figure 4-47.
5. Close the left side panel of the workstation as shown in the section “Closing the Left
Side Panel.”
