Fan Headers

is available for 4-pin fans only. The
fan speeds are controlled by Thermal

on the right for pin definitions.

A Chassis Intrusion header is located
at JL1. Attach an appropriate cable
from the chassis signal an intrusion

cated at JSTBY1 on the serverboard.
See the table on the right for pin defi-
nitions. (You must also have a card
