16 Gigabit PoE Ports for IP Cameras and Network Devices

The Dahua DH-CS4220-16GT-135 features 16 Gigabit RJ45 ports designed to deliver Ethernet connectivity and Power over Ethernet through compatible network cables.

This configuration is particularly useful for CCTV installations where multiple IP cameras require both network connectivity and electrical power. Instead of using separate power adapters for every compatible camera, installers can supply power directly from the PoE switch.

All 16 PoE ports support 10/100/1000 Mbps connectivity, making the switch suitable for Gigabit-capable devices as well as equipment operating at lower Ethernet speeds.

The switch can also connect compatible wireless access points, IP phones, and other PoE-powered devices. However, the total power requirements of all connected devices must remain within the available 135W budget.

135W Intelligent PoE Power Management

One of the most important features of the Dahua DH-CS4220-16GT-135 is its 135W total PoE power budget.

The switch supports different power levels across its PoE ports:

The higher-power ports are useful for compatible equipment requiring more power than standard PoE devices. These may include certain advanced security cameras or specialized networking equipment.

Importantly, the individual port ratings do not mean every port can deliver its maximum power simultaneously. The combined output remains limited to 135W.

The intelligent PoE system provides power consumption management and control over PoE power delivery. This helps administrators manage connected equipment and reduce problems associated with exceeding the switch's available power capacity.

Before installation, confirm the PoE standard and power requirements of each connected device.

20-Port Connectivity with Gigabit Ethernet and SFP Uplinks

The Dahua DH-CS4220-16GT-135 provides a practical combination of copper Ethernet and fibre connectivity.

Its 20 network interfaces are arranged as follows:

• Ports 1–16: 16 × 10/100/1000 Mbps RJ45 PoE ports.

• Ports 17–18: 2 × 10/100/1000 Mbps RJ45 uplink ports.

• Ports 19–20: 2 × 1000 Mbps SFP uplink ports.

The dedicated RJ45 uplinks allow the switch to connect to routers, other switches, and suitable network infrastructure without consuming the 16 designated PoE ports.

The two Gigabit SFP ports provide additional flexibility for fibre-based network connections. These are especially useful in business environments where networking equipment is installed in separate buildings, communication rooms, or distribution cabinets.

Compatible SFP transceivers and the correct fibre cabling are required for optical connectivity. The appropriate transceiver should be selected according to fibre type, link distance, and network design.

40Gbps Switching Capacity and Gigabit Performance

The Dahua DH-CS4220-16GT-135 delivers a manufacturer-rated 40Gbps switching capacity and 29.76 million packets per second forwarding rate.

These specifications make the switch suitable for handling traffic from multiple connected Gigabit Ethernet devices.

For surveillance networks, the switching capacity helps support simultaneous data transmission from connected IP cameras to recording and monitoring infrastructure. In office environments, it supports communication between compatible computers, network storage systems, access points, and other Ethernet equipment.

Additional performance specifications include:

• MAC address table: 8K entries.

• Packet buffer: 4 Mbit.

• Jumbo frame support: Approximately 15 KB.

• Network layer: Layer 2 switching.

Actual network performance will depend on connected equipment, traffic patterns, uplink capacity, cable quality, and network configuration.

Cloud Management and Network Administration

The Dahua DH-CS4220-16GT-135 supports web-based and cloud management, providing network administrators with options for managing supported switch functions.

This is particularly beneficial for businesses and surveillance installers who require greater control over network operation than a basic unmanaged switch provides.

The manufacturer's documented management capabilities include:

• Web-based network management.

• Cloud management.

• PoE power monitoring and control.

• VLAN functionality.

• STP/RSTP loop protection.

• DHCP client functionality.

• Ethernet flow control.

VLAN capabilities are useful when creating logical separation between different groups of network devices. For example, an administrator may want to organize surveillance equipment separately from other business network traffic.

STP and RSTP help protect Ethernet networks against switching loops that could disrupt connectivity.

Important: The DH-CS4220-16GT-135 has manufacturer documentation covering different hardware and management revisions. Specific VLAN options, cloud features, and hardware operating modes should be confirmed against the exact unit supplied.

Fibre Uplink Connectivity for Business Networks

The two Gigabit SFP uplink interfaces make this switch useful for installations requiring connections beyond standard copper Ethernet network layouts.

In a commercial building, for example, the switch can connect local IP cameras and PoE devices while using an appropriate fibre connection to communicate with upstream network equipment.

This arrangement can support structured network designs involving multiple floors, separate buildings, or centralized equipment rooms.

For professional network planning, configuration, fibre connectivity, and enterprise installations, businesses can explore networking expertise from OrbitLink Solutions.

The switch's SFP ports operate at Gigabit speed. They should not be confused with 10G SFP+ interfaces.

Durable Metal Housing and Installation Flexibility

The Dahua DH-CS4220-16GT-135 features a sturdy metal enclosure designed for professional networking environments.

The manufacturer specifies an operating temperature range of -10°C to +55°C, making it suitable for various indoor commercial and technical installations where environmental conditions remain within the supported limits.

Its desktop and rack-mounting options allow installation in network cabinets, communication rooms, and designated equipment spaces.

The switch uses a built-in power supply, eliminating the need for an external power brick in the standard configuration.

Although the metal enclosure is designed for durability, the switch should still be installed in an appropriate environment with sufficient ventilation and protection from moisture.
