3-2
3-2 Control Panel Button
Power
The main power button on each of the four control panels is used to apply or remove
power from the power supply to each of the four systems in the chassis. Turning off
system power with this button removes the main power, but keeps standby power
supplied to the system. Therefore, you must unplug system before servicing.
3-3 Control Panel LEDs
The four control panels are located on the front handle of the chassis.
Each control panel has three LEDs. These LEDs 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.
Overheat
This LED is illuminated when an overheat condition occurs.
A solid red LED indicates an overheat condition in the system.
A flashing red LED which flashes in one second intervals indicates a fan failure.
A flashing red LED which flashes in four second interfals indicates a power failure.
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 and air
shrouds are installed. Finally, verify that the heatsinks are installed properly. This
LED will remain flashing or on as long as the temperature is too high or a fan does
not function properly.
NIC1
Indicates network activity on GLAN1 when flashing.
