Verify the Component Problem

Purpose Test a component only if it is not associated with a previously reported router component

failure case and if testing will not compromise the integrity of the router and other

components.

Action To verify component failure:

1. Make sure that the component is well seated in its slot and connected to the router

midplane.

2. Perform a swap test on the component that has failed or has a problem. Take the

component offline if necessary, remove it, and replace it with one that you know works.

If the replaced component works, it confirms that there was a problem with the

component you removed.

NOTE: Before performing a swap test, always check for bent pins in the

midplane and check the component for stuck pins in the connector. Pins

stuck in the component connector can damage other good slots during a

swap test.

Fix the Problem

Problem If the router alarm condition is your responsibility, take action and correct it.

Solution For example, replace a dirty air filter, clean a fiber-optic cable, connect the component

securely to the midplane, or reset the component. Otherwise, escalate the alarm condition

and contact JTAC.

NOTE: Do not straighten component pins. If the pins on a component are

bent, return the component with a Return Material Authorization (RMA).

Straightening the pins may cause intermittent problems in the future.
