controller card
(OSP board) Section 5.2.5,
“Removing the
System Controller
Card” on page 5-17 This board implements the system controller
subsystem. The SC board contains a PowerPC
Extended Core, and a communications processor
that controls the host power and monitors host
system events (power and environmental). The
board holds a socketed EEPROM for storing the
system configuration, all Ethernet MAC
addresses, and the host ID. This board only
draws power from the 3.3V standby supply rail,
which is available whenever the system is
receiving AC input power, even when the system
is turned off. SC
