H165518:  DIFFERENCE BETWEEN 2 VRMS MADE BY DIFFERENT VENDORS


 TEXT:

 Difference between 2 VRMs made by different vendors.

 OVERVIEW:

 A Voltage Regulation Module (VRM) is shipped with this
 processor upgrade option. Two different versions of the VRM are
 available. One of the versions may rest on a component on the
 system board.
 They are interchangable - both are fully tested & warranted.

 DETAIL:

 There are two versions of this VRM - both fully tested,
 certified, and with full warranty. They are, however, produced
 by different suppliers, Semtech Corp. and VXI Electronics, and
 have different physical appearances due to different locations
 of heat sinks and other components.

 The original VRM (Semtech Corp.), FRU p/n01K7113, has nearly
 been phased out of production, and will not be seen often. The
 current VRM (VXI Electronics), FRU p/n01K7112, will be shipped
 in all FRU's and nearly all options. The VRM (VXI Electronics)
 FRU p/n01K7112, when installed, rests on component L21 mounted
 on the system board. This causes no problems. There is no
 thermal or electrical impact, and the VRM can be fully seated
 while contacting L21. Again, this VRM is fully tested and fully
 warranted.

 TRADEMARKS:

 Other company, product and service names may be the trademarks
 or service marks of others.
