SUPERSERVER 2027TR-D70RF+ USER'S MANUAL
3-2
3-2 Control Panel Buttons
•
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 power to the system off with this button removes the main
power, but keeps standby power supplied to the system. Therefore, you must
unplug the AC power cord from any external power source before servicing. The
power button has a built-in LED which will turn green when the power is on.
•
UID: When used with a UID compatible motherboard, the UID button is used
to turn on or off the blue light function of the LED. This is built into the front
side of the UID button and at the rear end of each motherboard node, for those
motherboards which support it. Once the blue light is activated, the unit can be
easily located in very large racks and server banks.
3-3 Control Panel LEDs
The four control panels are located on the front handle of the SC217 chassis.
Each control panel has two additional 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.
•
Alert: This LED is illuminated when an alert condition occurs. A solid red light
indicates an overheat condition in the system. A fl ashing red light which fl ashes
in one second intervals indicates a fan failure.
A fl ashing red light which fl ashes in four second interfals indicates a power failure.
When notifi ed of an alert, 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 fl ashing or on as long as the temperature
is too high or a fan does not function properly.
