Attention LED

System is up and running

Off

Blue

Used to identify a specific chassis in a rack or room. Use this LED for troubleshooting purposes such as replacing the fiber and field-replaceable units. You can control it through the software CLI.

Use the following command to activate this LED, manually:

hw-module attention-led location 0/RP0/CPU0

ACT LED (active controller)

After controller plug-in

Green

Red

Redundant controller unit (RCU) is enabled but the controller is missing from its slot or is faulty.

Green

RCU is enabled and the controller functions as an active controller.

Off

RCU is disabled.

ACT LED (backup controller)

After controller plug-in

Off

Red

RCU is enabled but the controller is missing from its slot or is faulty.

Yellow

RCU is enabled and the controller functions as a backup controller.

Off

RCU is disabled.

CCMD-16-C and CCMD-16-L Line Card LED


Note

In Release 24.2.11, the Cisco NCS 1020 chassis supports the Type 2 CCMD-16-C line card LEDs only.

The CCMD-16-C and CCMD-16-L optical line cards have 18 LEDs each to indicate the system status and the status of the optical ports.

The following information applies to both CCMD-16-C and CCMD-16-L cards.

Status

ACT

Amber (solid)

The line card is booting. This color appears when you insert the line card into the chassis.

Flashing Red

The line card is faulty.

Green

The line card is up and operational—not associated to the traffic status.

COM, A/D-1…A/D-16

Off

The port is not provisioned.

Red

Major alarm that could lead to a traffic impacting situation.

Green

The module is operational and has no alarm.

Amber (solid)

Minor alarm (such as low Rx or Tx power) that could lead to a traffic impacting situation.

Amber (flashing)

This is used for troubleshooting, to identify the faulty port of an LC.

Use the controller optics command in the configuration mode to point to a faulty port in the LC.

The port is configured in maintenance mode or the attention LED is enabled for this port.

Note

 

Attention LED is not supported on ACT LED.

Front Fan Tray LED

The fan tray has one LED to indicate its status.

Amber

There exists no input to the PSU, provided the other PSU is working.

Off

Both PSUs do not have input.

Green

The input to the PSU is valid.

NCS 1020 Front Door LEDs

The Cisco NCS 1020 Front Door (NCS1020-DR=) has two LEDs to indicate the system status and identify the chassis in the rack. the door LEDs mimic the ATT and SYS LEDs of the controller. This setup is done to avoid opening the door often to check the status of the chassis.


Note

The door LEDs come up only when you have properly mated the chassi connector with door connector.

For LED indications, see the SYS and ATT LEDs of the controller.
