How the QFabric parts fit together

A Juniper QFabric system has three roles. The QFX3100 Director provides provisioning and management for the system. QFX3500 and QFX3600 Nodes are the edge devices that connect servers and storage. The Interconnect, either the QFX3008-I chassis or the 1U QFX3600-I, carries traffic between Nodes. Most buyers on this page are keeping an existing QFabric system running, so start from the role of the part you are replacing.

Which Interconnect do I need?

Match what your system already runs. The QFX3008-I is a modular chassis with eight I/O slots for QFX3008-SF16Q cards, so a full chassis provides up to 128 40GbE QSFP+ ports. The QFX3600-I is a fixed 1U device with 16 40GbE ports. If you are adding ports to a QFX3008-I, you need QFX3008-SF16Q front cards; QFX3008-SR1 cards are the rear fabric cards in the same chassis.

Which airflow is the QFX3600-I-16Q-AFO?

Front-to-back: port-side intake, with air moving from the port side to the power supply and fan side. Juniper describes this model as port side to FRU side airflow. The QFXC01-PWRACI-650A is listed with FRU-to-port airflow, which is back-to-front (port-side exhaust), so check the airflow of every supply and fan against the chassis it goes into.

Is the QFX3100-NM-4GE copper or fiber?

Copper. Juniper lists the QFX3100-NM-4GE as the 4-port 10/100/1000BASE-T RJ45 card. The SFP version of the card has a different part number, so match the card to the cabling in your control plane network.
