1.3.1 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 nodes in the chassis. Turning power to the node 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
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 node. Once the blue light is activated, the unit can be easily located in very large
racks and server banks.
1.3.1 Control Panel LEDs
The four control panels located on the front handles of the Mondo chassis each have two LEDs. These LEDs provide you with
critical information related to its related node. This section explains what each LED indicates when illuminated.
Alert
This LED is illuminated when an alert condition occurs.
•
A solid red light indicates an overheat condition in the system.
•
A flashing red light which flashes in one second intervals indicates a fan failure.
•
A flashing red light which flashes in four second intervals indicates a power supply failure.
When notified of an alert, check the power cables and supplies and make sure all fans are operating normally.
This LED will remain flashing as long as the fan does not function properly or remain on steady for as long as the
temperature is too high.
NIC
This LED indicates network activity on either MGMT (ETH0) or ETH1 when flashing. These are not indicators for
eth2, 3, 4 or 5.
