Special Features of Compaq
ProLiant 5000 Servers
Compaq ProLiant 5000 servers have performance enhancement components
and management features not found in other servers. They include Processor
Power Modules, internal system monitor signals, and a terminator board that
resides on the I/O board in one- or two-processor systems.
Processor Power Modules (5V)
ProLiant 5000 servers utilize Processor Power Modules (redundant 5V DC-DC
converters) to ensure that proper voltage is delivered to critical operational
components including the processors, the I/O board and PCI buses. Maximum
Processor Power Module converter allocation is two on the I/O system board
(one is standard) and as many as three on each processor board.

unpopulated side
A single red LED on each Processor Power module, when illuminated,
indicates either a failure of that module or that another problem exists in the
system that is preventing the module from achieving its programmed voltage.
