Enabling Guided Cabling to Connect the Switching Plane Cables in a TX Matrix Plus Router with 3D SIBs

 

In a TX Matrix Plus routing matrix, there are two switch interface boards (SIBs) in a single plane in the SFC, whereas there is one SIB in a single plane in an LCC.

Guided cabling helps you interconnect the switching plane cables between the SFC SIBs and the LCC SIBs in a TX Matrix Plus routing matrix with 3D SIBs. Corresponding CBL LEDs on the SIBs in the LCC and the SFC blink simultaneously and help identify the correct port to be used for connecting the switching plane cables. You can use guided cabling to connect the switching plane cables after the installation of 3D SIBs on the LCCs and the SFC.

See Switching Plane Connections Between TXP-F13-3D SIBs and TXP-LCC-3D SIBs for the connection details between the LCCs and the SFC.

Before you enable guided cabling, ensure that:

  • The SFC and the LCCs are running Junos OS Release 14.1 or later.

  • The SFC and the LCCs are set up and all the TXP-F13-3D SIBs on the SFC and the TXP-LCC-3D SIBs on the LCCs are online.

  • All the switching plane cables and connectors are kept ready.

Note

Use guided cabling to connect the switching plane cables on all the LCCs serially one after another.

Note

You can activate guided cabling for one LCC at a time. Requests for connecting the SIBs of other LCCs are queued and taken up after the connections for the previous LCC is completed.

Enabling Port-by-Port Guided Cabling

 

To enable port-by-port guided cabling for connecting cables between SIBs of an SFC and an LCC:

  1. Verify that all the SIBs on both the SFC and the LCC are online by issuing the show chassis hardware sfc and show chassis hardware lcc commands.
  2. Enable guided cabling on the SFC by using the following command for the specific LCC:

    request chassis fabric guided-cabling lcc lcc-number enable port-by-port

    See Switching Plane Connections Between TXP-F13-3D SIBs and TXP-LCC-3D SIBs for the connection details between the LCCs and the SFC.

    Two peer CBL LEDs corresponding to the peer CXP ports on the SFC and the LCC SIBs start blinking red.

  3. Connect a switching plane cable between the blinking ports on the SIB in the SFC and the SIB in the LCC. The CBL LED stops blinking red and both the CBL and the LINK LEDs turn green if the connection and the link are functioning correctly. If the LEDs are lit yellow or red, investigate the cause of the problem and use a new switching plane cable if required. See Troubleshooting Switching Plane Connections to TX Matrix Plus TXP-F13-3D SIBs.

    If the cable is connected correctly, the LEDs turn green, else the state of the LEDs remains in the current cable state.

    If the connection is successful, the CBL LED on the next port starts blinking.

    Note

    Ports that are already connected are bypassed.

  4. Connect all the ports on the SIBs sequentially until all the SIBs on the SFC and the LCC are connected.
  5. Verify that the switching planes are working by using the show chassis fabric plane extensive command.Note

    If the cables do not transition to the CONNECTED state after a period of 15 minutes, then guided cabling is aborted for the specific LCC. You must enable guided cabling by issuing the request chassis fabric guided-cabling lcc lcc-number enable port-by-port command again.

Note

Guided cabling is not enabled for an invalid or an offline LCC.

Note

Guided cabling has to be resumed by issuing the command again, if the LCC or the SFC is restarted or the Switch Processor Mezzanine Board (SPMB) on the SFC or the LCC is restarted.

Enabling Plane-by-Plane Guided Cabling

To enable plane-by-plane guided cabling for connecting cables between the SIBs of an SFC and an LCC:

  1. Verify that all the SIBs on both the SFC and the LCC are online by issuing the show chassis hardware sfc and show chassis hardware lcc commands.
  2. Enable guided cabling by using the following command for the specific LCC.

    request chassis fabric guided-cabling lcc lcc-number enable plane-by-plane

    See Switching Plane Connections Between TXP-F13-3D SIBs and TXP-LCC-3D SIBs for the connection details between the LCCs and the SFC.

    All the CBL and LINK LEDs on a plane start blinking red.

  3. Connect the switching plane cables between the blinking ports on the SIBs in the SFC and the SIBs in the LCC, one after another. After successful connection, the LEDs stops blinking red and turn green.

    If the LEDs are still lit yellow or red after the cable is connected, investigate the cause of the problem and use a new switching plane cable if required. See Troubleshooting Switching Plane Connections to TX Matrix Plus TXP-F13-3D SIBs.

    When the ports on all the SIBs in a plane are connected, the CBL LEDs of the next plane start blinking.

  4. Connect all the ports on the SIBs sequentially until all the SIBs on the SFC and the LCC are connected.Note

    Ports that are already connected are bypassed.

  5. Connect all the SIBs in different planes sequentially.Note

    If a SIB is offline or faulty because of user intervention or a hardware fault, the SIB is bypassed and the next SIB is taken up for guided cabling.

    If you install a new SIB, it is connected only after it comes online within the time period for which guided cabling is enabled.

  6. Verify that the switching planes are working by using the show chassis fabric plane extensive command.Note

    If the cables do not transition to the CONNECTED state after a period of 15 minutes, then guided cabling is aborted for the specific LCC. You must enable guided cabling by issuing the request chassis fabric guided-cabling lcc lcc- number enable port-by-port command again.

Note

Guided cabling is not enabled for an invalid or an offline LCC.

Note

Guided cabling has to be resumed by issuing the command again, if the LCC or the SFC is restarted or the Switch Processor Mezzanine Board (SPMB) on the SFC or the LCC is restarted.

Disabling Guided Cabling

To disable guided cabling:

  • On a particular LCC, use the request chassis fabric guided-cabling lcc lcc-number disable command.

  • On all LCCs, use the request chassis fabric guided-cabling all-lcc disable command.

Note

If guided cabling is already completed or never activated, then disabling indicates failure.
