Connecting a QFX3600 Node Device to a QFX3008-I Interconnect Device

 

To form the data plane in a QFX3000-G QFabric system, you connect the QSFP+ uplink ports (labeled Q0 through Q7) on the QFX3600 Node device to the QSFP+ ports on the 16-port QSFP+ front cards in a QFX3008-I Interconnect device.

Note

By default, four ports (labeled Q0 through Q3) are configured for 40-Gbps uplink connections between your QFX3600 Node device and your Interconnect device. Optionally, you can choose to configure the first eight ports (labeled Q0 through Q7) for the uplink connections (see Configuring the Port Type on QFX3600 Node Devices).

Caution

For redundancy, each QFX3600 Node device must be connected to each QFX3008-I Interconnect device. For example, if you have two QFX3008-I Interconnect devices, then at least one uplink port on each QFX3600 Node device must be connected to each QFX3008-I Interconnect device. If you are connecting four uplink ports to two QFX3008-I Interconnect devices, we recommend connecting two uplink ports to each Interconnect device, each to a different front card. If you are connecting eight uplink ports to two QFX3008-I Interconnect devices, we recommend connecting four uplink ports to each Interconnect device, each to a different front card.

Warning

Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.

  1. If the fiber-optic cable connector is covered by a rubber safety cap, remove the cap. Save the cap.
  2. Remove the rubber safety cap from the QSFP+ optical transceiver on the QFX3600 Node device. Save the cap.
  3. Insert the cable connector into the optical transceiver.
  4. If the connector at the other end of the fiber-optic cable is covered by a rubber safety cap, remove the cap. Save the cap.
  5. Remove the rubber safety cap from the QSFP+ optical transceiver on the 16-port QSFP+ front card on the QFX3008-I Interconnect device. Save the cap.
  6. Insert the cable connector into the optical transceiver.
  7. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop. Placing fasteners on a loop helps cables maintain their shape.Caution

    Do not bend fiber-optic cables beyond their minimum bend radius. Bending the cables beyond their minimum bend radius can damage the cables and cause problems that are difficult to diagnose.

    Do not let fiber-optic cables hang free from the connector. Do not allow fastened loops of cables to dangle, which stresses the cables at the fastening point.
