Network Modules in a QFX3100 Director Device

The network module in a QFX3100 Director device (see Figure 1) is a field-replaceable unit (FRU) that you install in one of the two bottom slots on the front panel. The QFX3100 Director device is shipped with two network modules. You must power down the QFX3100 Director device before replacing a network module.

There are two types of network modules:

• RJ-45 network module—Provides four 1000BASE-T RJ-45 ports. See Cable Specifications for Control Plane Connections for the QFX Series for information about the required cables.
• SFP network module—Provides four 1-Gbps small form-factor pluggable (SFP) ports. See Interface Specifications for Control Plane Connections for the QFabric System for information about the supported transceivers and required cables.

Each network module provides four ports that connect the QFX3100 Director device to the QFX3000 QFabric switch control plane and management network and connect two QFX3100 Director devices to form a QFX3100 Director group.

Figure 1 shows the network module.
