Chapter 3
System Interface
3-1 Overview
There are several LEDs on two control panels as well as others on the drive car-
riers to keep you constantly informed of the overall status of the system as well
as the activity and health of specific components. The rear of the chassis includes
expander status and link LEDs. A main power button is also located on the right
side (only) control panel.
3-2 Control Panel Button
Power
The single button located on the right control panel is the power on/off button.
Depressing this button will either power both nodes on or off. Turning off system
power with this button removes the main power but keeps standby power supplied
to the system.
3-3 Control Panel LEDs
The two control panels located on the front of the chassis have several LEDs. These
LEDs provide you with critical information related to the node located on the same
side of the chassis. This section explains what each LED indicates when illuminated
and any corrective action you may need to take.
Power Fail
Indicates a power supply module has failed. The second power supply module will
take the load and keep the system running but the failed module will need to be
replaced. Refer to Chapter 5 for details on replacing the power supply. This LED
should be off when the system is operating normally.
