The Server Board supports the
PCI Bus Power Management Interface Specification
. Add-in cards
that support this specification can participate in power management and can be used to wake
the computer.

+5 V Standby Power Indicator LED
CAUTION
If the AC power has been switched off and the standby power indicator is
still lit, disconnect the power cord before installing or removing any devices
connected to the board. Failure to do so could damage the board and any of
the attached devices.
The Server Board’s standby power indicator, shown in Figure 3, is lit when there is standby power
still present on the board even when the computer appears to be off. For example, when this green
LED is lit, standby power is still present at the memory module sockets and the PCI
Express* connector.
