Chapter 3

System Interface

3-1 Overview

There are LEDs on the control panels and 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. Note that the server has four control panels, one

for each serverboard (node) installed in the system. This allows each severboard

to be controlled independently of the other.

3-2 Control Panel Buttons

There are two push-buttons located on each control panel: a power on/off button

and a UID button.

Power

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

power only to the node it is connected to. Depressing this button removes the main

power but keeps standby power supplied to the serverboard. This button has an

LED built into it, which will illuminate when its node is powered on.

UID

Depressing the UID (unit identiﬁ er) button illuminates an LED on both the front and

rear of the chassis for easy system location in large stack conﬁ gurations. The LED

will remain on until the button is pushed a second time. Another UID button on the

rear of the chassis serves the same function. This button has an LED built into it,

which will illuminate when either the front or rear UID button is pushed.
