Enabling or Disabling the Optical Module Laser

Enabling or Disabling the Optical Module Laser

This section describes how to enable or disable the optical module laser.

Usage Scenario

Before locating or troubleshooting a link failure, maintenance engineers should ensure that the optical module laser is disabled so that it cannot cause injury. The optical module can be configured to disable the laser automatically if it detects a link failure. The laser can also be disabled manually. If the optical module is configured to disable the laser automatically, the laser is not immediately re-enabled when the link failure is cleared. However, maintenance engineers can enable the optical module laser manually to check whether services have recovered.

Pre-configuration Tasks

Before enabling or disabling the optical module laser, complete the following tasks:

  • Power on the Router.
  • Ensure that the optical module has been installed and that the interface is Up.

Configuration Procedures

Figure 2-3 Flowchart for enabling or disabling the optical module laser

Disabling the Optical Module Laser

Disabling the optical module laser before troubleshooting a link failure protects maintenance engineers from the laser.

Context

Before locating or troubleshooting a link failure, maintenance engineers should ensure that the optical module laser is disabled so that it cannot cause injury. The optical module can be configured to disable the laser automatically if it detects a link failure. The laser can also be disabled manually.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number or controller cpos cpos-number

    The interface view is displayed.

    The interface can be a GE optical, POS, or CPOS interface.

  3. Perform either of the following operations:

    • Configure the optical module to disable the laser automatically.

      1. To configure the optical module to disable the laser automatically, run the laser autoshutdown enable command.

      2. (Optional) To configure intervals at which the optical module laser is disabled or enabled and the system checks for link failures, run the laser auto-shutdown-interval { open opentime-interval | close closetime-interval } command.

    • Disable the optical module laser manually.

      To disable the optical module laser manually, run the laser turn-off command.

      Running the laser turn-off command interrupts services on the interface. Therefore, do not run the command when the interface is working properly.

  4. Run commit

    The configuration is committed.

(Optional) Enabling the Optical Module Laser

After enabling the optical module laser, you can check whether the link failure is cleared.

Context

If the optical module is configured to disable the laser automatically, the laser is not immediately re-enabled when the link failure is cleared. However, maintenance engineers can enable the optical module laser manually to check whether services have recovered.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number or controller cpos cpos-number

    The interface view is displayed.

    The interface can be a GE optical, POS, or CPOS interface.

  3. Run laser turn-on [ duration duration ]

    The optical module laser is enabled, and the duration for which the optical module laser will be temporarily enabled is configured.

    The duration takes effect only after the laser autoshutdown enable command is run.

  4. Run commit

    The configuration is committed.

Verifying the Configuration of Enabling or Disabling the Optical Module Laser

After enabling or disabling the optical module laser, check its status.

Prerequisites

The optical module laser has been enabled or disabled as required.

Context

The following operations affect the status of the optical module laser:
  • Run the laser turn-on command to enable the optical module laser.
  • Run the laser turn-off command to disable the optical module laser.
  • Run the laser autoshutdown enable command to configure the optical module to disable the laser automatically if it detects a link failure.
  • Run the shutdown command to deactivate the interface.

Procedure

  1. Run the display laser status { interface interface-type interface-number | controller controller-type controller-number } command in any view to check the status of the optical module laser.

Example

Run the display laser status command to check the status of the optical module laser on GE 0/1/0.
