Chapter 3 System Interface

3-1 Overview

There are several LEDs on the two control panels as well as others on the SATA drive

carriers to keep you constantly informed of the overall status of the system as well as the

activity and health of speciﬁ c components. There are also two buttons on each control

panel. This chapter explains the meanings of all LED indicators and the appropriate

response you may need to take.

3-2 Control Panel Buttons

There are two push-button buttons located on each control panel: a reset button and a

power on/off button.

RESET : Depressing the reset button will reboot only the serverboard it is associated

with.

POWER : This is the main power button, which is used to apply or turn off the main

system power for the serverboard it is connected to only. Depressing this button

removes the main power but keeps standby power supplied to the serverboard.

3-3 Control Panel LEDS

Each of the two control panels located on the front of the NovaScale R422/R422-INF box

(CSE-808T-980B) has ﬁ ve LEDs. Each LED provides you with critical information related its

own speciﬁ c serverboard. This section explains what each LED indicates when illuminated

and any corrective action you may need to take.

Overheat/Fan Fail : When this LED ﬂ ashes, it indicates a fan failure. When on

continuously it indicates an overheat condition, which may be caused by cables

•

NOTE : The server has two control panels, one for each serverboard installed in the

system. This allows each severboard to be controlled independently of the

other.
