Diagnostic Indicators

Dell PowerEdge 6650

Diagnostic Indicators

Front Bezel Indicator

The system's bezel has an indicator that can represent system status when the bezel is installed. The active bezel indicator provides a 'go/no-go' on the overall health of the system. A blue backlit DELL indicates that the system is healthy, while an amber backlit alert indicator (exclamation point) indicates a system failure that requires service.

	A badge that is glowing blue indicates normal system function.
	An amber glow indicates a possible problem. Removing the bezel will allow access to the system LED panel which should provide more information on system status.

Rear LED Indicator

The Rear LED indicator is a bi-color LED (blue/amber) that mimics the operation of the front bezel indicator. This indicator provides for identification of the server in the alert state to service personnel that are operating from the backside of a rack enclosure and cannot see the bezel or LCD assembly.

The 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. The Rear LED indicator is connected to the system via a cable assembly and includes an outer lens for ID purposes.

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.

IMPORTANT - More Information NOTE: Systems management software causes the status indicator to blink to identify a particular system. For more information, see the systems management software documentation.

LCD Control Panel

Behind the bezel lies the LCD Control Panel assembly on the front of the system. The color-coding scheme matches that of the Active Bezel and provides the next level of information on system health. The bezel is optional, so the backlighting and character colors on the LCD panel provide the same alert indication as the amber indicator on the bezel.

In a normal state where the bezel indicator is blue, the LCD is also blue and is only showing informational messages. For any state where the Active Bezel is blinking amber, the LCD turns to amber characters on a black background.

There is a distinct correlation between the Active Bezel and the LCD.

When the Active Bezel is blue there are no errors displayed on the LCD (info only or nothing)
When the Active Bezel is blinking amber, error(s) are displayed on the LCD.

NOTE: The LCD backlight powered off when the bezel is attached. This is prevents the backlight from shining through the holes in the bezel and creating a distraction. When the bezel is removed the LCD backlight switches on, making the LCD visible.

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

Each SCSI hard-drive carrier has two indicators: a busy indicator and a status indicator. The indicators provide information on the status of the respective hard drive.

Below is a list of the SCSI hard-drive indicator codes. Different codes display as drive events occur in the system. For example, in the event of a hard-drive failure, the "drive failed" code appears. After the drive is selected for removal, the "preparing for removal" code appears. After the replacement drive is installed, the "preparing for operation, drive online" code appears.

Indicator Code

Indicator

Off	Drive bay empty, ready for insertion or removal
Steady green	Drive being prepared for operation, drive online
Blinks green four times per second	Identify drive
Blinks green twice per second at equal intervals	Drive being prepared for removal
Blinks green twice per second at unequal intervals	Drive rebuilding
Blinks amber four times per second	Drive failed
Blinks green, then amber, and then off, repeating this sequence every two seconds	Predicted failure for the drive

IMPORTANT - More Information NOTE: The drive-busy indicator signifies whether the hard drive is active on the SCSI bus. This indicator is controlled by the hard drive.

Power-Supply Indicators and Features

Each power supply has three indicators that indicate power-on status, fault, and whether AC power is present. These power supplies are hot-pluggable.

This is a picture of the 6650 power supply indicators

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. The Link Indicator will appear green, indicating the NIC is connected to a valid link partner. The Activity LED will blink amber to indicate that network data is being sent or received.

Expansion-Slot Indicator Codes

An indicator is located beside each PCI hot-pluggable expansion slot. The indicators show through the back-panel vents.

This is a picture of the 6650 expansion slot indicators

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 program 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.
