  • Performance: 7.2 Gbit/s switching capacity, 8000-entry MAC table
  • Management: web interface, DoLynk Care, 32 VLANs, LLDP topology
  • Installation: rack, metal housing, 440 × 220 × 44 mm, 2.29 kg
  • Power: built-in power supply, 212 W maximum consumption

Description

Network map and faults on your phone

The DoLynk Care app shows device status, flags errors in real time and sends notifications. Using LLDP, the switch draws the network topology so a problem camera is visible at once. PoE Watchdog restarts an unresponsive port by itself, loop protection stops broadcast storms, and long-distance PoE mode carries power up to 250 m, with speed dropping to 10 Mbit/s in that mode.

Who this network switch is for

Installers connecting up to 16 cameras in a warehouse, car park or hotel; technicians who watch several sites from the DoLynk Care app; and businesses that need a rack-mount PoE switch in a metal housing rated for −10 to 55 °C.

Questions & answers

How many cameras can a 190 W budget power?

There are 16 PoE ports with a 30 W maximum per port. With all ports in use that is about 11.8 W per port on average, so check the combined draw from your cameras' data sheets.

What speed are the ports?

The manufacturer data is inconsistent here: the port type is listed as gigabit, but switching capacity is 7.2 Gbit/s and the ET in the model code marks 10/100 Mbit/s ports in the Dahua range. If speed matters, confirm it in the manufacturer's data sheet.

Can it go in a server rack?

Yes, rack mounting is supported. It measures 440 × 220 × 44 mm, weighs 2.29 kg and has a built-in power supply.
