Incredible Perfect 24 Ports PoE Gigabit Switch for SMB Network

PLANET introduces the latest cost-effective Managed PoE Gigabit Switch – WGSW-28040P Series that is perfectly designed for SMB and SOHO PoE network construction. The WGSW-28040P Series is a 28-Port Gigabit Ethernet switch providing 802.3af Power over Ethernet on its first 24 Gigabit ports and 4 extra Gigabit TP/SFP combo uplink interfaces for connecting the PoE Switch to core network. Besides the user-friendly but advanced IPv6 / IPv4 management interfaces and abundant L2 / L4 switching functions, the WGSW-28040P Series applies the Green technology to provide energy saving, high speed and reliable office network environment. The WGSW-28040P Series is quite suitable for next generation network deployment and offers the lowest total cost of ownership. It is the best investment for business expanding or upgrading its network infrastructure.

High Performance
The WGSW-28040 Series provides 28 Gigabit Ethernet ports in which including 4 shared Gigabit SFP slots. It boasts high performance architecture of switch that is capable for providing the non-blocking switch fabric and wire-speed throughput as high as 56Gbps, which greatly simplifies the tasks of upgrading the LAN for catering to increasing bandwidth demands.

Easy Cabling Installation by Power over Ethernet
The PoE in-line power following the standard IEEE 802.3af makes the WGSW-28040P Series able to power on 24 PoE compliant devices at the distance up to 100 meters through the 4-pair Cat 5/5e UTP wire. With data and power over Ethernet from one unit, it can easily build a power centrally-controlled IP phone system, IP camera system, or Wireless AP group for the enterprises. Adopting the PoE technology for a wire carrying both data and power, the WGSW-28040P Series shall reduce cables deployment and the need for dedicated electrical outlets on the wall, ceiling or any unreachable place. Therefore, the WGSW-28040P Series helps the SMBs lower the installation costs, simplify the installation effort and eliminate the need of electricians or extension cords.

IPv6 / IPv4 Dual Stack
By supporting IPv6 management features and also backward compatible with IPv4, the WGSW-28040 Series helps the SMBs to step in the IPv6 era with the lowest investment but not need to replace the network facilities while the ISP constructs the IPv6 FTTx edge network.
