Control Panel Features
Feature
Description
Power Button
The main power button on each of the eight control panels is used to apply or remove power
from the power supply to each of the eight 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. The power button has a built-in LED
which will turn green when the power is on.
NIC
Indicates network activity on either LAN1 or LAN2 when flashing.
Information LED
See the table below for full details on the Information LED.
UID LED/BMC
Reset
This is a dual-function button. When used with a UID compatible motherboard, the UID
indicator 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. The button can also be used to reset the BMC firmware when
pressed for six seconds (see BMC Reset section).
