Connecting ATM-OC3-POM Ports to the Network
The following sections describe how to remove and install SFP modules, and how to connect the ports
on a module to the network.
Handling an SFP Module
Before handling an SFP module, observe the following guidelines:
•
•
The most common source of contaminants in the optical bores is debris picked up on the ferrules of the
Note
optical connectors. Use alcohol swabs or lint-free absorbent wipes to clean the ferrules of the optical
connector.
Removing an SFP Module
The following procedure describes removing an SFP module from the network module.

Color Meaning
Green Lit when carrier signal into the network module is present.
Green Blinks to indicate packet reception.
Green Blinks to indicate packet transmission.
Yellow Alarm indication signal.
Green Module has passed its self-tests and is available to the router.
SFP modules are static-sensitive. To prevent electrostatic discharge (ESD) damage, follow your
normal board- and component-handling procedures.
SFP modules are dust-sensitive. When storing an SFP module or when a fiber-optics cable is not
plugged into the connector, always keep plugs in SFP module optical bores.
