Fan Headers
The X7DBR-3/X7DBR-E has fi ve fan
headers, designated Fan1 through
Fan5. Fan speed is controlled via
Thermal Management with a BIOS
setting. See the table on the right
for pin defi nitions. (Pins 1-3 on the
headers are backward compatible
with traditional 3-pin fans.)
Serial Ports
The COM1 serial port is located on
the IO backplane. COM2 is a header
on the serverboard (see serverboard
layout for location). See the table on
the right for pin defi nitions.
Note: Pin 10 is included on the header but not on
the port. NC indicates no connection.

Power Supply Fail Header
Connect a cable from your power sup-
ply to the Power Fail header to provide
you with warning of a power supply
failure. The warning signal is passed
through the PWR_LED pin to indicate
a power failure. See the table on the
right for pin defi nitions.
