Power Button
The Power Button connection is

are backward compatible with tradi-
tional 3-pin fans. Fan speed control
is available for 4-pin fans only. The
fan speeds are controlled by thermal
management via IPMI. See the table
on the right for pin definitions.
Chassis Intrusion
A Chassis Intrusion header is located
at JL1. Attach an appropriate cable
from the chassis to inform you of a
chassis intrusion when the chassis
