Connecting a QFX5100 Node Device to a Fiber-Based QFX3000-G QFabric System Control Plane Network

Before you begin to connect a QFX5100 Node device to the fiber-based QFX3000-M QFabric system control plane network:

A QFX3000-G QFabric system control plane and management network is formed by connecting the QFX Series devices in your network to two Virtual Chassis composed of EX4200 or EX4300 switches. If you are creating a fiber-based control plane network, you use eight EX4200-24F or four EX4300-48P Ethernet switches in each Virtual Chassis. QFX5100 Node devices have an RJ-45 management port and one or two small form-factor pluggable (SFP) cages for copper or fiber SFP modules. For an all-fiber connection, place an 1 Gbps fiber SFP in the C0 and C1 management ports to connect the QFX5100 Node device to each Virtual Chassis, (see Figure 1.)

Use the following QFX5100 Node devices and EX Series switches for a fiber-based QFX3000-G QFabric system control plane network:

  • QFX5100 Node devices with two 1-Gbps SFP modules installed in the management ports labeled C0 and C1.

  • Virtual Chassis EX4200-24F or EX4300-48P switch members with an SFP+ uplink module installed.

To connect a QFX5100 Node device to the fiber-based QFX3000-G QFabric system control plane network:

Laser 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 SFP optical transceiver in the first management port (labeled C0) on the Node device management panel. Save the cap.
  3. Insert the cable connector into the optical transceiver.
  4. Connect the other end of that cable to the appropriate port on the first Virtual Chassis. See Table 1.
  5. Remove the rubber safety cap from the SFP optical transceiver in the second management port (labeled C1) on the Node device management panel. Save the cap.
  6. Insert the cable connector into the optical transceiver.
  7. Connect the other end of that cable to the appropriate port on the second Virtual Chassis. This should be the same port number that you connected to in Step 4. For example, if you connected the first cable to ge-0/0/0 on the first Virtual Chassis, you connect the second cable to ge-0/0/0 on the second Virtual Chassis.
  8. Repeat this procedure for each QFX5100 Node device.
  9. 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. An arc smaller than a few inches in diameter 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.
