1 Power-On Light: This green LED blinks when the server is in
Standby mode (power is present but the server is not turned on). The
blinking changes to a solid (continuous) light when you turn on your
server remotely (Unattended mode) or by pressing the Power-On
Switch. If this light is not on, the power cord is not connected or the
power supply has failed.
2 POST Complete Light: This green LED lights when the server
completes the power-on self-test (POST) without any errors.
3 SCSI Hard Disk Drive In-Use Light: This green LED lights when
your server is accessing a SCSI device. If this light remains
illuminated, it might indicate that either the SCSI bus or the system
microprocessor has stopped.
