Dahua-CS4218-16ET-240 18-Port Cloud Managed Desktop Switch with 16-Port PoE

Long Distance PoE
The transmission distance of a PoE port can be up to 250 m, meeting
the requirement of wired transmission (bandwidth reduced to 10
Mbps).
PoE Watchdog
Adopts the innovative PoE Watchdog. PoE Watchdog can be switched
on by dialing/turning on the WEB page switch. It enables the switch
to automatically detect port status and restart the failed ports to
recover connection in case of IPC connection exception. This enables
intelligent operation and maintenance management in its true sense
and effectively reduces manual maintenance costs.
Loop Protection
When a loop is detected, the loop alarm will be triggered and the
elimination mechanism will activate to prevent broadcast storms from
occurring
Highly intuitive, the Smart Managed Switch can manage local
networks. With the DoLynk Care platform, it can also perform cloud
management. The switch performs operation and maintenance using
topology visualization on front-end, transmission and back-end storage
devices that are in the security system and IT system. With its full
metal design, the switch has great heat dissipation and can operate in
temperatures ranging -10°C to 55°C. It offers EMC and has protection
against overvoltage, overcurrent, static electricity, lightning strikes,
pulses and other types of interference. For the PoE series Smart
Managed Switch, power is supplied up to 250 meters away. The
orange port supplies up to 60 W and the red port provides up to 90 W.
Also, link aggregation and STP are available on select models to ensure
