58 SRKA4/ISP4400 Server System Product Guide
Power Subsystem
The SRKA4 MP Server System can accommodate up to three power supply modules, each of
which is enclosed in a power subsystem bay. The power subsystem bay contains a power
distribution board (PDB). This board manages the power delivered by all functional power supply
modules.
If all power supply modules are functioning and there is still a problem with powering on the
server system, turn off the system by using the power on/off switch on the front panel AND unplug
all AC power cords. Remove the power subsystem bay and send it back to an Intel customer
service representative. Before sending the bay back, make sure all power supply modules are
removed from the system.
