The Blackmagic Ethernet Switch 820 is a low-latency Ethernet switch designed for SMPTE-2110 broadcast systems. It carries eight 100G QSFP28 ports and two 10G RJ45 ports on the rear panel, with front-to-back cooling from six fans and two internal 100-240V AC power supplies for redundancy. Routing happens at the front panel, where a 2.2 inch LCD monitors video, audio, standard and timecode and a search dial scrubs between every input, while a 2110 IP monitor-out sender publishes the switch name, link speed and a live data-transfer graph for each port at 1080p. Two redundant PTP clock Ethernet ports carry IEEE 1588-2008 PTP v2, so two grandmaster clocks can keep the network in sync through an equipment failure or maintenance window, and a dedicated 1G NMOS control port keeps IS-04 and IS-05 traffic off the media network, alongside a separate 1G management port for configuration and firmware. It connects naturally to a HyperDeck ISO Recorder 100G or Blackmagic Cloud Store Ultra, or forms the core of a SMPTE-2110 network built around ATEM Constellation IP switchers.
