The beaconing function for an individual server may get turned on or off by pressing the combination button
and LED. See

for details.
The power button and LED allows you to manually take a server temporarily out of service but leave it in a

Connectors

management tasks to be done directly rather than remotely. The port uses the KVM dongle device included
in the chassis accessory kit. See
KVM Cable, on page 85
for more information.
