System LED panel

Lit LED Description Action
Power-on This green LED is lit (solid) when 12 VDC is present on the midplane.  
Location This blue LED is lit (solid or flashing) to indicate the location of the BladeCenter S system or that a condition has occurred that has caused the remote system management to identify the BladeCenter S system as needing attention. Look for any information or error LEDs on the system LED panels, the modules, and the blade servers in the BladeCenter S system.
Over-temperature This amber LED is lit (solid) to indicate that the system temperature has exceeded a threshold level.
  1. Determine whether a fan module has failed. If it has, replace the fan module as soon as possible.
  2. Make sure that the room temperature is not too high. (See Features and specifications for temperature information.)
  3. Make sure that there is a blade server, module, or filler installed in each bay
Information This amber LED is lit (solid) to indicate that a noncritical event has occurred, such as the wrong I/O module inserted in a bay, or power requirements that exceed the capacity of the power modules currently installed.
  1. Check the advanced management module event log for errors.
  2. Check to see if there are any other LEDs lit on the BladeCenter S system.
  3. Check to see of an LED on one or more blade servers is lit. If so:
    1. Check the advanced management module event log for errors related to that blade server.
    2. Remove the blade server and open the cover to view the system board LEDs.
      Note: You can view the status of the LEDs on the blade server without opening the blade server cover. From the advanced management module Web interface, click the name of the blade server in the Blade LEDs section of the LEDs link.
System error This amber LED is lit (solid) to indicate that a critical system error has occurred, such as an error in a power module or a system error in a blade server.
  1. Check the advanced management module event log for errors.
  2. Check to see if there are any other LEDs lit on the BladeCenter® unit.
  3. Check to see if an LED on one or more modules is lit. If so, following the instructions for that LED in Module LEDs.
  4. Check to see if an LED on one or more blade servers is lit. If so:
    1. Log in to the advanced management module and view the event log for errors related to that blade server.
    2. Remove the blade server and open the cover to view the system board LEDs.
      Note: You can view the status of the LEDs on the blade server without opening the blade server cover. From the advanced management module Web interface, click the name of the blade server in the Blade LEDs section of the LEDs link.
