Supervisor Module LEDs

LED

Color

Status

STATUS

Green

All diagnostics pass. The module is operational (normal initialization sequence).

Red

Indicates one of the following:

  • The module has detected a slot ID parity error and will not power on or boot up.
  • The module is not fully inserted and does not have a reliable connection to the midplane.
  • The diagnostic test has failed.

Flashing red

Indicates one of the following:

  • The inlet air temperature of the system has exceeded the safe operating temperature limits of the module (a major environmental warning). The module has been shut down to prevent permanent damage. The system will be shut down after two minutes if this condition is not cleared.
  • The module is resetting, and both ejector levers are out.

Off

The module is not receiving power.

ID

Flashing blue

The operator has activated this LED to identify this module in the chassis.

Off

This module is not being identified.

SYSTEM

Green

All chassis environmental monitors are reporting okay.

Amber

At least one power supply has failed or the power supply fan has failed.

Red

The temperature of the supervisor engine major threshold has been exceeded.

Off

The slot has detected a slot ID parity error.

ACTIVE

Green

The supervisor module is operational and active.

Amber

The supervisor module is in standby mode.

PWR MGMT

Green

Sufficient power is available for all of the installed modules.

Amber

Insufficient power is available for all of the installed modules.

MGMT ETH

Green

The management port is operational.

Amber

The management port link has been disabled through the software.

Flashing amber

The management port link is bad and has been disabled due to a hardware failure.

Off

The module has not detected a signal.

LINK

Green

The module has detected a link.

Off

The module does not detect a link.

ACT

Flashing green

The module is transmitting or receiving.

Off

The module is not transmitting or receiving.

LOG FLASH

Green

The log flash CompactFlash or USB disk is being accessed. Do not remove the media until the LED is off.

Off

The expansion flash CompactFlash or USB disk is not being accessed. You can remove the media while this LED is off.

Slot 0

Green

The expansion flash CompactFlash or USB disk is being accessed. Do not remove the media until the LED is off.

Off

The log flash CompactFlash or USB disk is not being accessed. You can remove the media while this LED is off.

I/O Module LEDs

LED Color Status

ID

Flashing blue

The operator has activated this LED to identify this module in the chassis.

Off

This LED is not being used.

Status

Green

All diagnostics passed. This module is operational (normal initialization sequence).

Red

Indicates one of the following:

  • The module has detected a slot ID parity error and will not power on or boot up.
  • The module is not fully inserted, and it is not making a reliable connection with the supervisor.
  • The module has failed diagnostic tests and has powered down.

Flashing red

Indicates one of the following:

  • The switch has just been powered on, and the module is resetting.
  • The module is resetting and both ejector levers are out.
  • The module has been inserted during the initialization process.
  • The module could not power up because of insufficient power.
  • An overtemperature condition has occurred. A major temperature threshold has been exceeded during environmental monitoring

Off

The module is not receiving power.

Link (for each port)

Green

The port is active (the link is connected and active).

Orange

The port is disabled by the operator or is not initializing.

Flashing orange

The port is faulty and disabled.

Off

The port is not active or the link is not connected.

Fabric Module LEDs

LED

Color

Status

Status

Green

All diagnostics pass. The module is operational (normal initialization sequence).

Red

Indicates one of the following:

  • The diagnostic test has failed. The module is not operational because a fault has occurred during the initialization sequence.
  • The inlet air temperature of the system has exceeded the safe operating temperature limits of the card (a major environmental warning). The card has been shut down to prevent permanent damage.

Flashing red

Indicates one of the following:

  • The fabric module has just been inserted and is booting up.
  • An overtemperature condition has occurred and the module has powered down.
  • The power was turned off with a CLI command.
  • The module is resetting and both ejector levers are out.

ID

Flashing blue

The operator has activated this LED to identify this module in the chassis.

Off

This module is not being identified.

Fan Tray LEDs

LED

Color

Status

STATUS

Green

The fan tray is operational.

Flashing red

One or more fans is running below the threshold speed.

The fan tray is receiving insufficient power.

Off

No power is going to the fan tray.

ID

Flashing blue

The operator has activated this LED to identify this module in the chassis.

Off

This module is not being identified.

FABRIC STATUS

Green

All diagnostics pass. The module is operational (normal initialization sequence).

Red

Indicates one of the following:

  • The diagnostic test has failed. The module is not operational because a fault has occurred during the initialization sequence.
  • The inlet air temperature of the system has exceeded the safe operating temperature limits of the card (a major environmental warning). The card has been shut down to prevent permanent damage.

Flashing red

Indicates one of the following:

  • The fabric module has just been inserted and is booting up.
