Memory Extender Boards

The 32-DIMM memory extender board has two power status LEDs, 1.25 V and 1.5 V (Figure 5-5). When the
LEDs are on, each respective voltage is present on the memory extender board.
The 16-DIMM memory extender board has one condition LED on each of the two VRMs. If either condition
VRM LED is on, there is a problem with that VRM. You must replace the entire extender board in this case;
the VRMs are not customer self-repair units.
