System Interface

3-1 Overview

There are several LEDs on the chassis control panel as well as others on the

SATA/SCSI 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 the chassis 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-buttons located on the front of the chassis. These are (in order

from left to right) a UID button and a power on/off button.

 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 gura-

tions. 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.

 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.
