provide you with critical information related to different parts of the system. This section
explains what each LED indicates when illuminated and any corrective action you may
need to take .

module will take the load and keep the system running but the failed module will
need to be replaced. Refer to Chapter 6 for details on replacing the power supply.
This LED should be off when the system is operating normally .

warm. Check the routing of the cables and make sure all fans are present and
operating normally. You should also check to make sure that the chassis covers are
installed. Finally, verify that the heatsinks are installed properly (see Chapter 5). This
LED will remain flashing or on as long as the indicated condition exists .
