LEDs

You can perform the following check on LEDs that assist you with the troubleshooting process:

Chassis LED

The LEDs indicate whether each type of module (Route Processor, line cards, fabric cards, fan trays, and power supplies) is fully functional or have a fault condition.

Table 1. Chassis LED Descriptions
LED Color Status

ATTN (Attention)

Blue

The operator has activated this LED to identify this chassis.

Off

The chassis is not functional.

Port Status LEDs


Note


The 8800-LC-48H does not have port LEDs.

Each port on the 8800-LC-36FH has an LED. The following table describes port status LEDs.

Status

ATTN (Attention)

Flashing Blue

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

Off

The operator had not activated the LED to identify the fan tray in the chassis.

FT STS

Amber

The fan tray is powered on.

Green

The fan tray is operational.

Flashing amber

The module has minor alarm.

Flashing red

The module has active major or critical alarms.

Flashing green

FPD upgrade in-progress.

Off

No power to the fan tray.

FC STS

Amber

The fabric cards are powered on and is in one of the following states:

  • Either one or more fabric cards behind this fan tray is not operational.

  • Either one or more fabric cards behind this fan tray have minor, major or critical alarm.

Green

  • One of the fabric modules is operational and other one not present.

  • Both fabric cards behind this fan tray are operational.

Off

If both the fabric modules behind this fan tray are plugged out (or not present).

Temperature Warning Label

Every fan tray has a temperature warning label beside its handle. The temperature warning label is temperature sensitive. At normal operating temperatures (less than 55°C), the warning label has a black background with black edges. At temperatures above 55°C, the background color changes to white and the edges’ color changes to red.

Color

Status

Attention

Flashing blue

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

Off

This module is not being identified.

Status

Green

This router processor is operational with no issues.

Flashing green

The auto or manual FPD upgrade in-progress.

Flashing amber

The module has minor alarm.

Flashing red

The module has active major or critical alarms.

Amber

The module is in one of the following states:

  • Power cycle

  • Reload or reimage

  • Shutdown

Red

For 8800-RP:

  • BIOS boot failure. Also, the Attention LED remains blue.

For 8800-RP2:

  • BIOS boot failure.

  • Card power-up failure. Also, the Attention LED remains Off.

    This allows you to distinguish the status between BIOS boot failure and card power-up failure.

Off

The module is not enabled.

Active

Green

The RP/RSP is in the Active state.

Off

The RP/RSP is in the Standby state.

GPS

Green

The GPS interface is provisioned and frequency, time of day and phase inputs are all operating correctly.

Off

The GPS interface is not provisioned, or the GPS inputs are not working correctly.

Sync

Green

The frequency, time, and phase are synchronized to an external interface. The external interface could be:

  • BITS

  • GPS

  • Recovered RX Clock

Amber

The system is running in holdover or free-run mode and it is not synchronized to an external interface.

Off

The centralized frequency or time and phase distribution is not enabled.

GNSS

Green

GNSS receiver interface is up.

Off

GNSS receiver interface could be:
