The motherboard includes processor modules, slots for 16
DIMMs, memory control subsystems, and the service processor
(iLOM) subsystem.

The service processor (integrated LOM) subsystem controls the
host power and monitors host system events (power and
environmental). The integrated LOM controller draws power
from the host’s 3.3V standby supply rail, which is available
whenever the system is receiving AC input power, even when
the system is turned off.

This board distributes main 12V power from the power supplies
to the rest of the system. It is directly connected to the paddle
card, and to the motherboard via a bus bar and ribbon cable. It
also supports a top cover interlock (“kill”) switch.

In the Sun Fire X4240, the power supplies connect directly to the
power distribution board.

This board serves as the interconnect between the power
distribution board and the fan power boards, drives backplane,
and I/O board.

These boards carry power to the system fan modules. In
addition, they contain fan module status LEDs, and transfer I
data for the fan modules.

This board includes the connectors for the drives, as well as the
interconnect for the I/O board, Power and Locator buttons, and
system/component status LEDs. The Sun Fire X4240 has a
16-disk backplane. Each drive has an LED for power/activity,
fault, and ok-to-remove.
