wired router Mikrotik RB450Gx4 Gigabit Ethernet Green

The RB450Gx4 is a wired Gigabit Ethernet router by MikroTik with five Gigabit Ethernet ports, one serial port, a microSD card slot and 1024 MB of internal memory. It supports wide-range DC input (10–57 V) via two power jacks or PoE (802.3af/802.3at or passive PoE) and can provide PoE output on Ethernet port #5. The device is supplied without an enclosure and shares form factor compatibility with previous RB850 and RB450 series enclosures. RouterOS powers the unit and enables routing, firewalling and bandwidth management with hardware IPsec acceleration and a quad-core ARM CPU.

Advantages

Compact form factor compatible with existing RB850/RB450 enclosures, full Gigabit Ethernet ports and a microSD slot provide flexible deployment and storage options. Wide input voltage range and multi-mode PoE support allow versatile power configurations, while the quad-core ARM CPU, 1 GB RAM and hardware IPsec support deliver reliable performance for encrypted tunnels and high-throughput routing. RouterOS offers extensive configuration and networking features for professional use.

Suitable for

• Small and medium office routing and firewall tasks
• Remote sites requiring flexible PoE power options
• Home lab and network testing with microSD storage
• Deployments needing hardware-accelerated IPsec VPNs

How to use

Install the device in a suitable enclosure if required, connect the WAN and LAN devices to the Gigabit Ethernet ports, and provide power via the preferred power jack or PoE method. Insert a microSD card for additional storage if necessary. Access RouterOS through Winbox, WebFig or SSH to configure interfaces, firewall rules, routing and VPNs. Enable IPsec hardware acceleration in RouterOS settings for encrypted traffic where applicable.

Recommendations

For stable operation, use a compatible enclosure to protect the board, ensure adequate ventilation, and supply clean DC power within the 10–57 V range; when running high-throughput or many IPsec tunnels, monitor CPU and memory usage and consider firmware updates from MikroTik for security and performance improvements.
