Dell PowerEdge 2650

Diagnostic Indicators

System-Status Indicators

The system's bezel has an ActiveID indicator that represents system status when the bezel is installed. The indicator signifies when the system is operating properly, or needs attention. The back-panel indicator functions the same as the bezel indicator. The back-panel indicator connector allows an indicator to be attached that will also function the same as the bezel indicator.

A caution code signifies a problem with microprocessors, power supply, system or power-supply fans, system temperature, hard drives, system memory, expansion cards, or integrated SCSI controller.

 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.

System Identification Indicators

The identification buttons on the front and back panels can be used to identify a particular system within a rack.

When either of the identification buttons is pushed, the identification indicator on the back blinks until one of the buttons is pushed again. If the bezel is installed, the system status indicator will also blink. If an indicator is connected to the back-panel system status indicator connector, that indicator will also blink.

Systems management software can also be used to cause the status and identification indicators to blink to identify a particular system.

Front-Panel Indicators and Features

Additional indicators are located behind the bezel. The front-panel status LCD provides information using an alphanumeric character display.

 Component  Description

  Power button   Turns system power off and on.

  • If you turn off the system using the power button and the system is running an ACPI-compliant operating system (such as Microsoft Windows 2000), the system can perform an orderly shutdown before power is turned off.
  • If the system is not running an ACPI-compliant operating system, power is turned off immediately after the power button is pressed.

The button is enabled in the System Setup program. When disabled, the button can only turn system power on.

  
  Power indicator

  

Provides information on power status.

  
  CD and Diskette drive indicators   Indicates read or write access to the respective drive.  
  Hard-drive indicators   Provide information on the status of the respective hard drive.  
  NIC indicators

   Indicate whether the NIC has a valid link to the network.  
  Status LCD   Can signify when the system is operating correctly or when the system needs attention.  
  System identification button   Can be used to identify a particular system within a rack.  
  NMI button

  

Can be used to troubleshoot software and device driver errors when using certain operating systems. This button is often referred to as a "force dump switch" and can be pressed using the end of a paper clip. When the option is enabled in the System Setup program and the button is pressed, an NMI alerts the system.

Use this button only if directed to do so by qualified support personnel or by the operating system's documentation.

  

Back-Panel Indicators and Features

The table below describes the back panel indicators.

 Component  Description

  Power supply indicators   Provides information on power status  
  NIC indicators   Provides information on NIC status  
  System status indicator connector   Connects to an indicator that can signify when the system is operating correctly or when the system needs attention.  
  System identifications indicator   Signifies when the system is operating correctly or when the system needs attention, and can identify a particular system.  
  System identification button   Can be used to identify a particular system.  

Power-Button Indicator

The power button controls the power input to the system's power supplies. The power button indicator can provide information on power status.

 Indicator  Indicator Code

  On   Indicates that power is supplied to the system, and the system is operational.  
  Off   Indicates that no power is supplied to the system.  
  Blinking   Indicates that power is supplied to the system, but the system is in a standby state. For more information on standby states, see your operating system documentation.  


Power-Supply Indicator

Each hot-pluggable power supply has indicators that can provide information on power status, fault, and the presence of power.

This is a picture of the PowerEdge 2650 power supply diagnostic indicators

 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.).  
  Power Present   Green indicates that power is present at the power supply and that the system is connected to a power source.  


SCSI Hard-Drive Indicator

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.

Different codes display as drive events occur in the system. For example, in the event of a hard-drive failure, the "drive fail" 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.

   This is a picture of the PowerEdge 2650 SCSI drive indicators

 Drive Status Indicator  Indicator Code

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

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.


NIC Indicator

Each NIC on the back panel has an indicator that provides information on network activity and link status.

The front panel has a link indicator for each NIC. Each indicator signifies whether the corresponding NIC is connected to a valid link partner on the network.

 Indicator  Indicator Code

  Link and activity indicators are off.   The NIC is not connected to the network.  
  Link indicator is green   The NIC is connected to a valid link partner on the network.  
  Activity indicator is amber blinking.   Network data is being sent or received.  


Cooling Fan Indicator

Each individual fan has a status indicator on the system board adjacent to the respective fan's connector.
