Installing VRMs
To install VRMs follow these steps.
1. Perform all of the steps in "Removing VRMs". You are ready to install new VRMs if your
system looks like Figure 2-55. on page 64.
2. Carefully unpack the replacement VRMs and identify the Master and Slave. The notch
in the VRM will align with the key in the connector. Also, the part number on the VRM
distinguishes between Master and Slave.
3. Insert the Master VRM firmly in the top slot from the chassis floor.
4. Insert the Slave VRM in the slot closest the chassis floor.
5. Inspect and verify that the ejector tabs are in the locked position. The tabs lock in place
when the VRMs are fully seated in their respective connector.
6. Grasp the power supply and slide the tab into the support strap.
7. Replace the four T-15 Torx screws. Reference Figure 2-54. on page 64.
8. Replace the left side panel. Reference "Left Side Panel" on page 16.
