Power LED/Speaker/Keylock
On JF2, pins 2, 4, and 6 are for the
power LED, pins 1, 3, 5 and 7 are for
the speaker and pins 8 and 10 are for
the keylock. See the tables on the
right for pin defi nitions.
Note: The speaker connector pins are
for use with an external speaker. If
you wish to use the onboard speaker,
you should close pins 5 and 7 with a
jumper. Utilizing the keylock header
allows you to inhibit any actions made
on the keyboard, effectively "locking"
it.
Overheat LED
Connect an LED to the JOH1 header
to provide warning of chassis over-
heating. See the table on the right for
pin defi nitions.
Chassis Intrusion
A Chassis Intrusion header is located
at JL1. Attach the appropriate cable
to inform you of a chassis intrusion.
Wake-On-LAN
The Wake-On-LAN header is desig-
nated JWOL. See the table on the
right for pin defi nitions. You must
have a LAN card with a Wake-On-LAN
connector and cable to use the Wake-
On-LAN feature.
(Note: Wake-On-LAN from S3, S4, S5
are supported by LAN1. LAN2 sup-
ports Wake-On-LAN from S1 only.)
