Chapter 3: System Interface Chapter 3 System Interface 3-1 Overview There are several LEDs on the control panel as well as others on the SCSI drive carriers and the motherboard 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 the chassis control panel and an on/off switch on the power supply. 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-button buttons located on the front of the chassis. These are (in order from left to right) a reset button and a power on/off button.
RESET l RESET: The reset switch reboots the system. l POWER: This is the main power switch, 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. (See also the power supply on/off switch in Section 3-5.) 3-1
