Series Overview
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
the network remains stable. The switch can be used in small and
medium-sized businesses such as supermarkets, offices, restaurants,
cafés and hotels.
Functions
Cloud Management
Devices can be managed through the Do Link Care app and performs
real-time monitoring of the network. The app also displays the
status of devices, triggers alarms for errors in real time and sends
notifications.
Network Topology Management
Supports the LLDP protocol and is able to generate and display the
network topology, so that you can quickly identify issues, and perform
operation and maintenance remotely on devices that are in the
topology.
BT 90W (Red Port)
The red ports support IEEE802.3af, IEEE802.3at, IEEE802.3bt and Hi PoE standards, with a maximum output power consumption of 90W
per port. Suitable for powering high-power devices.
