1 Overview
1.1 Introduction
The product is a hardened switch. Equipped with a high performance switching engine, the switch
performs optimally. It has low transmission delay, large buffer and is highly reliable. With its full
metal and fanless design, the device has great heat dissipation and low power consumption,
working in environments ranging from –30 °C to +65 °C (-22 °F to +149 °F). The protection for
power input end overcurrent, overvoltage and EMC can effectively resist the interference from
static electricity, lightning, and pulse. The dual power backup guarantees stable operation for the
system. With web management, SNMP and other functions, the device can be remotely managed.
In addition, based on the DoLynk Care Cloud Server, this device can be managed through the
DoLynk Care app, the network topology diagram function can be used to quickly locate the
problem. The device is applicable for uses in different scenarios, including buildings, homes,
factories and offices.
1.2 Features
●
Features mobile management by app.
●
Supports network topology visualization.
●
Support one-stop maintenance.
●
100/1000 Mbps downlink electrical ports (PoE) and 1000 Mbps uplink electrical ports or optical
ports.
The uplink ports might differ depending on different models.
●
Supports IEEE802.3af, IEEE802.3at standard. Red ports support IEEE802.3bt, and are compatible
with Hi-PoE. Orange ports conform to Hi-PoE.
●
Supports 250 m long-distance PoE power supply.
In Extend Mode, the transmission distance of the PoE port is up to 250 m but the transmission
rate drops to 10 Mbps. The actual transmission distance might vary due to power consumption
of connected devices or the cable type and status.
