16+2F Gigabit Network Managed Industrial Ethernet Switch
Managed Industrial Ethernet Switch Overview
The LNK-GY216M is a full Gigabit Layer 2+ managed industrial Ethernet switch
featuring 16x Gigabit RJ45 ports + 2x SFP uplinks, all supporting wire-speed forwarding.
It offers advanced L2+ management, including IPv4 static routing, ACL/QoS policies, VLAN segmentation,
and robust security mechanisms. To ensure high network reliability, this product
supports STP/RSTP/MSTP (<50ms) and ERPS (<20ms) ring protocols, thereby ensuring
fast failover during link failures.
The industrial-grade durability of the product is evidenced by its 6KV surge-protected,
IP40-rated aluminium alloy casing, dual DC power inputs and fanless cooling, which ensures
a 35-year MTBF in harsh environments (extreme temperatures, EMI and vibrations). It is ideal
for smart transportation, power grids, mining, oil/gas, and green energy, and enables stable,
efficient networks via Web/CLI/SNMP/Telnet management.
Managed Industrial Ethernet Switch Features

in ring or chain networks for simplified networking.
- Full Gigabit high-speed transmission with stable, high-bandwidth performance;
supports per-port speed and flow control.
- with 10M/250m long-distance extension, solving Ethernet cable communication limitations
- Industrial-grade high-bandwidth switching chip with high backplane capacity
and large packet buffer to reduce network congestion.
- IEEE 802.3x full-duplex flow control for smooth high-definition,
large bitstream transmission without packet loss.
- Supports automatic MAC address learning/updating and Auto MDI/MDI-X on all ports
- Service ports with 6KV surge protection plus power short-circuit
and overload protection for enhanced reliability.
- Rugged aluminum alloy housing with strong heat dissipation, anti-interference shielding,
corrosion resistance, and durability.
- Dual DC redundant power inputs with wide voltage range (DC 12–57V) for industrial applications
- DIN rail mounting, IP40-rated protection, and wide operating temperature range (-40℃ to +75℃)
for stable operation in harsh environments.
- Fanless, low-power, silent design for easy installation and long-term reliability
