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 specific components. There are also two buttons on each control panel. This chapter explains the meanings of all LED indicators and the appropriate re- sponse you may need to take. Note that the server has two 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
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 identifier) button illuminates an LED on both the front and rear of the chassis for easy system location in large stack configurations. 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.
