Introducing a new Gigabit Managed POE Switch for future-proof deployments

With layer 3 managed Gigabit Ethernet Switch, It provides IPv6/IPv4 management and built-in L2/L4 Gigabit Switching engine, and supports high-speed transmission of surveillance images and videos.
The SIL-B48M3POE1G500 Smart PoE+ Switch with 48 1000BASE-T PoE+ ports and four 10G SFP+ slots,It delivers advanced management features with an 256Gbps switching capacity. The SIL-B48M3POE1G500 is equipped with 1000BASE-T PoE+ ports that provide higher gigabit speeds capable of up to 1000Mbps over existing Cat5e or better cabling. This switch provides eight PoE+ connections with a Max power budget of 500W, and supplies up to 30W of power per port for devices such as wireless access points, PTZ IP cameras, and VoIP telephony systems.

1000Mbps Capability for Diversified Bandwidth Applications

With the terminal access rates of 802.11ac wireless APs reaching as high as 1Gbps, 100M ports has been unable to satisfy the demand. Supporting 1Gbps capability and 802.3af/at POE output, the SIL-B48M3POE1G500 can deliver not only data to 802.11ac wireless APs, but also power to other powered devices such as APs and IP cameras.

10 Gbps SFP Ports Optimize Network Performance

The SIL-B48M3POE1G500 provides greater bandwidth and powerful processing capacity. It offers a maximum 40Gbps uplink bandwidth through the Four 10Gbps SFP+ ports. In addition, the administrator can flexibly choose the suitable SFP/SFP+ transceiver according to the transmission distance or the transmission speed required to extend the network efficiently.

Cost-effective IPv6 Managed Gigabit Ethernet Switch Solution

With layer 3 managed Gigabit Ethernet Switch, It provides IPv6/IPv4 management and built-in L2/L4 Gigabit Switching engine, and supports high-speed transmission of surveillance images and videos.

Surge Protection Design

Reaching 6KV surge protection, the Ethernet ports owns the capacity to keep the Ethernet Switch from lightning strikes and other electrical surges, offering reliable performance even in some harsh environments.
