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 off system power with this button removes the main power, but keeps stand-
by power supplied to the system. Therefore, you must unplug system before servic-
ing. 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.
Control Panel LEDs
The four control panels are located on the front handle of the SCF424 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.
Informational LED:
Continuously on and blue: UID function has been activated.
Flashing red: Fan failure.
Continuously on and red: Overheat condition. This may be caused by cables
obstructing the airflow in the system or the ambient room temperature being too
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. This LED will
remain flashing or on as long as the overheat or fan failure condition exists.
NIC: Indicates network activity on either LAN1 or LAN2 when flashing
