A full Gigabit Power-over-Ethernet (PoE) switch is now available from Korenix UK. The switch provides embedded 48V DC boosting, making it suitable for advanced onboard vehicle IP surveillance, transportation and industrial automation applications.

The JetNet 3906G-w is an industrial grade, 6-port PoE switch that is suitable for Mega Pixel IP camera surveillance applications in harsh industrial environments and transportation. The switch also offers a wide ambient operating temperature range of -40°C to 75°C, making it suitable for a diverse range of installations.

With its 12-36V DC PoE boost, the switch enables the use of PoE and higher rate PoE, as well as 48V DC. The embedded DC booster accepts DC power at 12V or 24V and then boosts this voltage up to 48V, while still providing PoE capability. As standard PoE installations typically require a separate 48V DC inverter, the JetNet 3906G-w can be supplied as a single box solution, saving the customer installation space, while reducing associated cabling and wiring costs.

Santos Muro, business development manager at Korenix UK commented, “The JetNet 3906G-w is well suited for environments where there is no access to a 48V DC power supply such as buses, trams, trains and emergency response vehicles, which typically operate on 24V DC power supply. The switch is also extremely compact and so can be mounted out of sight in cabinets, or in limited spaces on buses, trains and other vehicles. The wide operating temperature range and rugged design also ensure that the switch can operate in semi-Arctic conditions as well as hot, humid, dusty environments.”

The JetNet 3906G-w conforms to IEEE Power-over-Ethernet standards, IEEE 802.3af / IEEE 802.3at. The switch is a ready to fit unit that requires no configuration. Six ports are provided – one of these being an SFP fibre optic port for 100Mbps or 1000Mbps fibre optic connections for long distance transmission. Four Gigabit RJ-45 PoE ports are provided (30W per port, 120W in total), as well as one Gigabit RJ-45 port.

The JetNet 3906G-w supports 9KB Jumbo frames (large frame forwarding capability) and so is suitable for Mega Pixel IP surveillance across long distances (up to 120km).

As Santos Muro stated, “Some industrial plants contain equipment and production machinery that generates very high levels of electrical noise and electromagnetic interference, which can scramble video images and signals. For these types of applications, where fibre optic cabling is required rather than copper, the JetNet 3906G-w offers this functionality at an affordable price.”
