Power On LED
The Power On LED connector is lo-
cated on pins 15 and 16 of JF1 (use
JLED for a 3-pin connector). This
connection is used to provide LED
indication of power being supplied to
the system. See p. 5-4 and the table
on the right for pin defi nitions.
NMI Button
The non-maskable interrupt button
header is located on pins 19 and 20
of JF1. Refer to p. 5-4 and the table
on the right for pin defi nitions.
Fan Headers
There are eight fan headers on the
serverboard, all of which are 4-pin
fans. Pins 1-3 of the fan headers are
backward compatible with the tradi-
tional 3-pin fans. (Fan speed control
is supported with 4-pin fans only.)
See the table on the right for pin defi -
nitions. The onboard fan speeds are
controlled by Thermal Management
(via Hardware Monitoring) under the
Advanced Section in the BIOS.
Serial Ports
Two serial ports are included on the
serverboard. COM1 is a backpanel
port and COM2 is a header located
near the PCI-E slot 1. See the table
on the right for pin defi nitions.
