Overview
Cisco UCS B420 M3 High Performance Blade Server
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 Interpreting LEDs, on page 25 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 69 for more information.
