The Reset button is recessed in the front panel of the server. You can press the button with 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 do not work.
The locator function for an individual server may get turned on or off by pressing the locator button/LED.
The power button allows you to manually take a server temporarily out of service but leave it in a state where
it can be restarted quickly. If the desired power state for a service profile associated with a blade server is set
to "off," using the power button or Cisco UCS Manager to reset the server will cause the desired power state
of the server to become out-of-sync with the actual power state and the server may unexpectedly shut down
