Cabling the Gigabit Ethernet Line Cards

This chapter provides cabling instructions and information for the interfaces on the Gigabit Ethernet Line Card (GLC2), the four-port Quad Gigabit Ethernet Line Card (QGLC), and 10 Gigabit Ethernet Line Card (XGLC).

These cards support 802.3z-compliant Gigabit Ethernet interface(s) which connect the chassis to other elements in the packet data network.

This chapter includes the following sections:

Gigabit Ethernet Line Card (GLC2)

The following figure shows the single-port GLC2. The front panel of this card is labeled "Ethernet 1000". This card supports a single fiber or copper Small Form-factor Plugin (SFP) transceiver module as described below:

Class 1 Laser Compliance Notice

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.

Quad Gigabit Ethernet Line Card (QGLC)

The following figure shows the four-port Quad Gigabit Ethernet Line Card (QGLC). The front panel of this card is labeled "Ethernet 1000".

RJ-45 SFP Module Detail

The following describes the RJ-45 (copper) SFP module for the GLC2 and the QGLC with pinouts and definitions.

Important:

To comply with GR-1089 intra-building, lightning-immunity requirements and ensure compliance with FCC Radiated Emissions Criteria, you must use shielded-twisted pair (STP) cable and assure that it is properly terminated at both ends.

The 1000Base-TX interface is suitable for connection to intra-building or unexposed wiring or cabling only. These intra-building ports MUST NOT be metallically connected to interfaces that connect to the outside plant (OSP) or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 5) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

The following light emitting diode (LED) status indicators are provided on the Gigabit Ethernet line cards:

  • Link: This green LED shows whether or not the line card is connected to the network. The LED is illuminated when the card is connected.

  • Activity: This green LED shows when data is transmitted or received. The LED is illuminated when data is passing through the interface.

Cabling the Optical SFP+ Interface

To interconnect the optical SFP+ interface on the XGLC, follow the instructions below.

Important:

Be sure to label the interface cable with its destination prior to connecting it to the XGLC. 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.


Note

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   Remove the cover from the SFP interface.
    Step 2   Insert the optical cable from a network device into the interface and ensure that it is securely in place.

    XGLCs can be installed in chassis slots 17 through 23 and 26 through 32. These cards should always be installed directly behind their respective PSCs, PSC2s, or PPCs, but they are not required behind any redundant packet processing cards (those operating in Standby mode).
