A DC-powered fiber switch with 12 1000/10000BASE-X SFP+ ports and 36 100/1000BASE-X SFP ports.
The EX4400-48F-DC has a 550 W DC power supply, front-to-back airflow, and supports up to 10 units as a single logical device through a 400 Gbps Virtual Chassis interconnect. It provides 456 Gbps unidirectional and 912 Gbps bidirectional packet-switching capacity, with 678 Mpps Layer 2/Layer 3 throughput. The switch measures 17.39 x 1.72 x 16.93 inches (44.17 x 4.37 x 43 cm) with the power supply and fans installed and weighs 13.01 lb (5.9 kg) without a power supply or fan module.
