Hardware Support
Power Connectors
The Desktop Board has two power connectors. See Figure 13 on page 34 for the
location of the power connectors.
Fan Headers
The Desktop Board has a 3-pin MCH fan header and a 3-pin chassis fan header. See
Figure 12 on page 33 for the location of the chassis fan header.
+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 attached devices.
The Desktop Board's standby power indicator, shown in Figure 4, is lit when there is
standby power to the system. This includes the DIMM socket and the PCI bus
connector, even though the computer appears to be off.
