Troubleshooting 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 the system needs attention. The back-panel system status indicator functions the same way 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 and hard drives. The CD and diskette drives have green activity indicators. The front-panel LCD provides status information using an alphanumeric character display.

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.

SCSI Hard-Drive Indicator Codes

	Condition		Indicator Code

	Identify drive		All three drive status indicators blink simultaneously.
	Drive being prepared for removal		All three drive status indicators flash sequentially.
	Drive ready for insertion or removal		All three drive status indicators are off.
	Drive being prepared for operation		The drive online indicator is on. The drive activity light may flash briefly.
	Drive bay empty		All three drive status indicators are off.
	Drive predicted failure		The drive online indicator is on. The drive failure indicator blinks on briefly each second.
	Drive failed		The drive online indicator is off. The drive failure indicator blinks off briefly each second.
	Drive rebuilding		The drive online indicator blinks rapidly.
	Drive online		The drive online indicator is on.

Power-Supply Indicators and Features

Each power supply has three indicators that indicate power-on status, fault, and the presence of AC power. These power supplies are hot-pluggable.

Power Supply Indicator Codes

	Indicator		Indicator Code
	Power-On		Green indicates that the power supply is operational.
	Fault		Red indicates a problem with the power supply (fan failure, voltage error, etc.).
	AC Present		Green indicates that AC power is present at the power supply and that the system is connected to an AC source.

NIC Indicators

Each NIC has two indicators that indicate network activity and a valid link partner.

NIC Indicator Codes

	Indicator		Indicator Code
	Off		The NIC is not connected to the network.
	Link (Green )		The NIC is connected to a valid link partner.
	Activity (Amber blinking)		Network data is being sent or received.

Expansion-Slot Indicator Codes

An indicator is located next to each PCI hot-pluggable expansion slot.

Expansion-slot indicators (6)

Expansion-Slot Codes

	Indicator		Indicator Code
	Off		Expansion-slot power is off. No action is required.
	Green		Expansion-slot power is on. No action is required.
	Green, blinking fast		Expansion slot is being identified by an application or driver. No action is required.
	Amber, blinking slow		Expansion card is faulty or improperly installed, causing a problem with power supply to the card.
	Amber blinks twice, pauses, and then repeats the sequence		Expansion card of a slower operating speed was hot-plugged. If you are replacing an expansion card with a card of a slower operating speed, you must power down the system to install the replacement card.
