Cleaning Dirty Fiber Optic Connectors
To prevent dirt and dust from collecting on the fiber optic connectors, avoid touching all surfaces after cleaning the connectors, and keep all unused ports covered.
Fiber optic transceivers are sensitive optical devices that need to be handled carefully. If dirt collects on the fiber optic connectors, you may notice the following:
■The Link Status LED (for the receive fiber) on the ATM Module does not light.
■The Far End Status LED does light.
■Degraded performance on that port, indicated by an increase in the Errors Received statistic counter. The Errors Received statistic counter is described in “ATM Port Statistics” on page
To clean fiber optic connectors on the ATM Module:
1Remove any accumulated dust or debris from the connector by blowing canned air over all surfaces.
Do not use commercial compressed air or house air, because of the risk of oil contamination.
2Reconnect the cable to the port to see if the dusting corrected the problem.
If the LED still indicates a problem, clean the cable connectors.
