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.

Control Panel LEDs
The four control panels are located on the front handle of the SC827 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 fl ashing red LED which fl ashes in one second intervals indicates a fan failure.
A fl ashing red LED which fl ashes 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 cov-
ers and air shrouds are installed. Finally, verify that the heatsinks are installed
properly. This LED will remain fl ashing or on as long as the temperature is too
high or a fan does not function properly.
NIC1: Indicates network activity on GLAN1 when fl ashing.
