Table 6 describes the functions of the LEDs on the ATM-OC3-POM network module shown in

Figure 17.

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:

• 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.

Note The most common source of contaminants in the optical bores is debris picked up on the ferrules of the

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.
