Connecting a QFX3008-I Interconnect Device to a Fiber-Based QFX3000-G QFabric System Control Plane Network

Before you begin to connect a QFX3008-I Interconnect Device to the fiber-based QFX3000-G 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. QFX3008-I Interconnect Devices have four small form factor pluggable plus (SFP+) management ports on each Control Board (CB0 and CB1). Use the SFP+ management ports to connect the QFX3008-I Interconnect Devices to each Virtual Chassis (see Figure 1).

Specific ports have been reserved on the Virtual Chassis to connect to the Interconnect devices, Node devices, and QFX3100 Director devices in your QFabric system. Such design simplifies installation and facilitates timely deployment of a QFabric system. It also enables the use of a standard Virtual Chassis configuration (see Example: Configuring a Fiber-Based Control Plane for the QFX3000-G QFabric System).

To connect each QFX3600-I Interconnect device to the fiber-based 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.

Note:

Before you connect each cable to a device, if the fiber-optic cable connector is covered by a rubber safety cap, remove the cap. If the transceiver is covered with a rubber safety cap, remove the cap. Save the caps for future use.
