Cabling the Channelized Line Cards

This chapter provides information about the physical interfaces and instructions for installing the cables on the CLC2 (STM-1/OC-3).

This chapter includes the following sections:

Channelized Line Card Interfaces

The CLC2 card supports two types of Small Form-factor Pluggable (SFP) transceiver modules. The type of optical fiber interface on the line card is dictated by the SFP modules installed on the card. The SFP modules are hot-pluggable.

Important:

The SFP interface is only certified to work with SFP transceiver modules purchased from Cisco for use with the CLC2.

Important:

Because of the optical SFP interface, this product has been tested and found to comply with the limits for Class 1 laser devices for IEC825, EN60825, and 21CFR1040 specifications.

The following figure shows the LC-connectors for the CLC2. Each SFP fiber interface provides both transmit (TX) and receive (RX) on the port.

Cabling the Optical SFP Interface

To use the optical SFP interface on the a channelized line card, follow the instructions below.

Important:

Be sure to label the interface cables with their destination prior to connecting them to the CLC2. This will assure proper reconnection should the card need to be serviced.


Note

Only trained and qualified personnel should install, replace, or service this equipment.

Invisible laser radiation may be emitted from the aperture of the port when no cable is connected. Avoid exposure to laser radiation and do not look into open apertures. Be sure to keep the cover on the interface when it is not in use.

    Step 1   To ensure full connectivity, use your thumb to firmly press the SFP transceiver module into its socket on the front panel of the card.
    Step 2   Remove the cover from the SFP interface.
    Step 3   Inspect and clean the connector's fiber-optic end-faces.
    Step 4   Insert the fiber-optic optical cable from a network device into the interface and ensure that it is securely in place.
    Step 5   Repeat step 1 through step 4 to connect a fiber-optic cable to other ports, if so equipped.
