System LEDs

• There is a set of four LEDs located on the
  desk-side and rack-mount systems front bezel that
  are used for diagnosing the health of the system.
  
• These LEDs warn of any impending failures and
  allow you to take preventive action. For example,
  you may want to make a system backup or replace a
  system component before it quits functioning.
• The remaining four LEDs are the power, system,
  LAN, and locator LEDs.
• This section explains how the systems LEDs can
  be used for troubleshooting system problems and
  locating the system you want to work on within a
  rack of systems.
• Here is a list of the types of LEDs section
• Power and System LEDs
• LAN LED
• Locator LED and Button
• Diagnostic LEDs

LEDs Status

• LAN LED
• The LAN LED provides an indication as to whether
  the system is communicating over
• the LAN. When the LAN LED is solid green, there
  is no system LAN communication taking place, but
  the system is ready to communicate over the LAN.
• When the LAN LED is blinking green, the system
  is communicating over the LAN.

Locator LEDRack System Only

• The locator LED provides a means for locating
  the system on which you intend to work.
• For example, you find out that system number 5
  in your rack of systems has a LAN cable
• that needs to be replaced. This will require
  that you walk all the way around to the back
• of your rack of systems to replace the cable.
  Once you get behind the rack of systems, you
• need to locate the system that needs the cable
  replaced.
• The locator LED makes this an easy task. When
  the locator button is pressed in, the locator LED
  begins to flash blue at
• a frequency of one blink per second both on the
  front of the system and the back, thus
• making it easy to locate the system on which you
  need to work.
• The locator LED can also be activated or
  deactivated by use of the locator button on the
• back panel of the system or by use of a
  Management Processor (MP) command. Or using the
  Command line interface

Diagnostics LED

• There are four diagnostic LEDs located on the
  front bezel of the system.
• These faults are placed in categories that are
  appropriate to the system problem they indicate
  (for example, memory faults,system board faults,
  etc.).
• The red LEDs are used to identify the fault
• category of the LED error message. For example,
  if LED one is the only red LED, the error message
  is for a memory fault. If LEDs one and two are
  red, the error message is for a processor fault.
• The column for the e-buzzer code in the
  following tables associates that code with a LED
  error message however, in some cases there is no
  e-buzzer code associate with a LED error message
• Note
• Use the fault tables to diagnose a problem when
  the system light is blinking red.
• Use the warning tables to diagnose a problem
  when the system light is blinking orange.
