Carefully lift up the Pentium II Xeon processor and remove it.3.1.5 Installing and Removing a VRM (VoltageRegulator Module)Each Pentium II Xeon processor requires two VRMs (VoltageRegulator Modules), one for the processor and another one for the L2cache. However, two L2 caches share one VRM. If you are installingtwo Pentium II Xeon processor, you need three VRMs: two VRMs foreach processor and one VRM for both of the L2 cache to share.Refer to section 3.1.2 for the location of the VRM sockets. Thefollowing table shows the VRM socket allocation:VRM Socket Slot 2 SocketVRM Socket 1 (CN4) CPU 1VRM Socket 2 (CN11) L2 cache of CPU 1 and 2VRM Socket 3 (CN18) CPU 2VRM Socket 4 (CN20) CPU 3VRM Socket 5 (CN23) L2 cache of CPU 3 and 4VRM Socket 6 (CN29) CPU 4
