Chapter 11 Connecting ATM Network Modules ATM OC-3 Network Modules - SFP-OC3-MM • Single-mode intermediate reach (SMI) - POM-OC3-SMIR - SFP-OC3-IR1 • Single-mode long reach (SML) - POM-OC3-SMLR - SFP-OC3-LR1 ATM-OC3-POM Network Module LEDs Table 11-7 describes the functions of the LEDs on the ATM-OC3-POM network module shown in Figure 11-17. Table 11-7 ATM-OC3-POM Network Module LEDs LED RXCR RXCL TXCL RXALM EN Color Green Green Green Yellow Green Meaning Lit when carrier signal into the network module is present. Blinks to indicate packet reception. Blinks to indicate packet transmission. Alarm indication signal. Module has passed its self-tests and is available to the router. 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.
