on the processor subsystem, there are two system attention leds, one on the dca and the other on the back of the system. for the specific locations of these leds, refer to the following illustration.

   

    the two leds are tied together, so they will always be in the same state, either both on or both off. they are referred to as the system attention led. the system attention led is turned on when an entry is made in the service processor error log that gets transmitted to the system-level error logs (the aix error log and the service action event log in service focal point). when the attention light comes on, these error logs should be examined to see if user intervention is required.

    if a hardware problem is indicated, call service support.
