Introduction
For use with Intel Pentium II Xeon processor-based servers only
IMPORTANT:
This server is not equipped with chassis interlocks. There are
board interlocks that connect the memory board, processors, peripheral
board and power switch cable into one interlock chain.
When one of the connected components in the interlock chain is improperly
seated in the connector, the LED associated with the fault origination point will
illuminate. See Table 1-1 and Figure 1-1 for details regarding the interlock
error.
