Chapter 3 System Interface

3-1 Overview

There are several LEDs on the control panel to keep you constantly informed of the
overall status of the system as well as the three buttons described below.

3-2 Control Panel Buttons

There are three buttons located on the front of the chassis: a UIB button, a reset
button and a power on/off button.

Reset

Use the reset button to reboot the system.

Power

This is the main power button, which is used to apply or turn off the main system
power. Turning off system power with this button removes the main power but keeps
standby power supplied to the system.

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.
