Description
1
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.
2
NIC
Indicates network activity on either LAN1 or LAN2 when flashing.

Information LED
See the table below for full details on the Information LED.
4
UID LED
When used with a UID compatible serverboard, 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 serverboard 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.
