Troubleshooting
Disk Activity LED (front panel)
The Disk Activity LED on the front panel indicates the state of hard
drive and optical drive activity on the system.
NOTE: The Activity LED automatically communicates with hard
drives, optical drives and optical drives connected to the built-in SCSI
controller. To communicate with drives attached to PCI-card
controllers, connect the card to the system board using an LED
activity cable.
LAN LEDs (front and rear panels)
The LAN Activity LED on the front panel of the system blinks when
network activity is present.
The two LAN LEDs on the rear panel of the system provide
additional information about LAN activity. These LEDs are part of
the LAN connector.
