Chapter 3
System Interface
3-1 Overview
There are several LEDs on the control panel as well as two for each SCSI
drive carrier and LAN (Ethernet) port. These LEDs are to keep you con-
stantly informed of the overall status of the system and the activity and
health of specific components. There are also two buttons on the chassis
control panel.
3-2 Control Panel Buttons
There are three push-button buttons located on the front of the chassis.
These are (in order from left to right) a power on/off button, an NMI (Non-
Maskable Interrupt) button and a reset button.
!
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.
!
NMI: NMI stands for "non-maskable interrupt". Pressing this button
issues a non-maskable interrupt to force the server into a halt state. This is
used for diagnostic purposes, and allows you to perform a memory down-
load to determine the cause of a problem.
