Blade Servers

LEDs

The LED indicators indicate whether the blade server is in active or standby mode, the status of the network
link, the over all health of the blade server, and whether the server is set to give a flashing blue beaconing
indication. See
The removable hard disks also have LEDs indicating hard disk access activity and hard disk health.

Buttons

The Reset button is just inside the chassis and must be pressed using the tip of a paper clip or a similar item.
Hold the button down for five seconds and then release it to restart the server if other methods of restarting
are not working.
The beaconing function for an individual server may get turned on or off by pressing the combination button
and LED. See
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
