Installing SFPs and cabling the Brocade 7800

Perform the following steps to install SFPs and cable the switch.

  1. Install the SFP transceivers in the Fibre Channel ports, as required. The ports selected for use in trunking groups must meet specific requirements. For a list of these requirements, see the Brocade Fabric OS Administration Guide.
    1. Remove the plugs from the ports to be used.
    2. Position a transceiver so that it is oriented correctly and insert it into a port until it is firmly seated and the latching mechanism clicks.

      For instructions specific to the type of transceiver, see the transceiver manufacturer’s documentation.

      NOTE
      The transceivers are keyed to ensure correct orientation. If a transceiver does not install easily, ensure that it is correctly oriented.
    3. Repeat steps a and b for the remaining ports, as required.
  2. If you have chosen to use the optical ports for ge0 and ge1, install those SFPs. If you have licensed the additional GbE ports, install the SFP transceivers in GbE ports ge2 through ge5.
    1. Remove the plugs from the ports to be used.
    2. Position a transceiver so that it is oriented correctly and insert it into a port until it is firmly seated and the latching mechanism clicks. Be sure that you are using Brocade-branded 4 Gbps SFPs in the GbE ports.
    3. Use the portcfggemediatype command to configure ge0 and ge1 to either copper or optical.

      For instance, to select the optical option for port ge0, use the following command.

      switch:admin> portcfggemediatype ge0 optical
  3. Connect the cables to the transceivers.

    The cables used in trunking groups must meet specific requirements. For a list of these requirements, see the Brocade Fabric OS Administration Guide.

    NOTE
    A 50-micron cable should not be bent to a radius less than 2 in. under full tensile load and 1.2 in. with no tensile load. Tie wraps are not recommended for optical cables because they are easily overtightened.
    1. Orient a cable connector so that the key (the ridge on one side of connector) aligns with the slot in the transceiver. Then, insert the cable into the transceiver until the latching mechanism clicks. For instructions specific to cable type, see the cable manufacturer’s documentation.
      NOTE
      The cable connectors are keyed to ensure correct orientation. If a cable does not install easily, ensure that it is correctly oriented.
    2. Repeat Step a for the remaining cables as required.
    3. If you have chosen the copper option for GbE ports ge0 and ge1, you can install those cables now.
  4. Check the LEDs to verify that all components are functional. For information about LED patterns, see the LED patterns section.
  5. Verify the correct operation of the Brocade 7800 by entering the switchShow command from the workstation.
