Cisco UCS 5108 Installation Guide

The beaconing function for an individual server may get turned on or off by pressing the combination button
and LED. See Interpreting LEDs, on page 36 for details.
The power button and LED allows you to manually take a server temporarily out of service but leave it in a
state where it can be restarted quickly.
Connectors
A console port gives a direct connection to a blade server to allow operating system installation and other
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.
