As a Layer 3 switch it handles routing at the rack. Virtual Chassis supports 2 members, so a pair can be managed as one switch. A 2.2 GHz quad-core Intel processor, 16 GB of memory and a 100 GB SSD run Junos OS 20.2R1 or later.
Power comes from 2 x 650 W AC supplies, 1+1 redundant and hot-swappable. Cooling uses 5 x QFX5110-FANAFI modules in a 4+1 redundant setup, with back-to-front (AFI) airflow. The switch weighs 11 kg.
