Diagnostic Indicators

System Status Indicators

The system's bezel has an indicator that can represent system status (when the bezel is installed). The indicator identifies when the system is operating properly or when it needs attention. The back-panel system status indicator functions the same as the bezel's status indicator. A caution code identifies a problem with power supply, system or power-supply fans, system temperature, hard drives, or expansion cards.

System Status Indicator Codes

	Status Indicator		Caution Indicator		Back Panel Indicator		Indicator Code
	Off		Off		Off		No power is available to the system, or the system is not powered on.
	On		Off		Blue		The system is operating normally.
	Off		Blinking		Amber Blinking		The system has detected an error and requires attention.
	Blinking		Off		Blue Blinking		The system is identifying itself.
							NOTE: Systems management software causes the status indicator to blink to identify a particular system. For more information, see the systems management software documentation.

Front-Panel Indicators and Features

Additional indicators are located behind the bezel for system power, NIC activity, system status, and hard drives. The CD and diskette drives have green activity indicators.

Description

	Blue and amber system status indicator			The blue system status indicator lights up during normal system operation. The server management software can also cause the blue system status indicator to flash to identify a particular system. The amber system status indicator flashes when the system needs attention due to a problem with power supplies, fans, system temperature, or hard drives. NOTE: If the system is connected to AC power, the amber system status indicator will flash regardless of whether the system has been powered on.
	NIC1 and NIC2 link and activity indicators			The link and activity indicators for the two integrated NICs light when the NICs are in use.
	Hard-drive indicator			The green hard-drive activity indicator flashes when the hard drives are in use
	Power button			The power button lights when the system power is on.

SCSI Hard-Drive Indicators

If the integrated RAID controller is activated or an optional RAID controller card is installed in the system, three indicators on each of the hard-drive carriers provide information on the status of the SCSI hard drives. The SCSI backplane firmware controls the drive-online and drive-failure indicators.

The table below lists the drive indicator patterns established by the SCSI backplane firmware. Different patterns are displayed as drive events occur in the system. For example, in the event of a hard-drive failure, the "drive failed" pattern appears. After the drive is selected for removal, the "drive being prepared for removal" pattern appears, followed by the "drive ready for insertion or removal" pattern. After the replacement drive is installed, the "drive being prepared for operation" pattern appears, followed by the "drive online" pattern.

NOTE: If the integrated RAID controller is not activated or an optional RAID controller card is not installed, you will see only the "drive online" and "drive bay empty" indicator patterns.
