Locating the controller in a data center

Before you begin

Procedure

  1. Find the controller requiring maintenance in the data center.
    • Look for a lit blue identify LED on the front or rear of the controller.

      The front identify LED is behind the controller front bezel and might be difficult to see if the bezel is installed.


      Front identify LED - on
    • Check the tags attached to the front of each controller for a matching part number.
  2. Remove the controller front bezel, if one is installed, to access the front panel controls and indicators.
  3. Optional: Turn off the blue identify LED if you used it to locate the controller.
