ADC KRONE introduces new TrueNet Midspan Power-over-Ethernet Controller

ADC KRONE presents its latest product developments in the field of Power-over-Ethernet (PoE). The new TrueNet Midspan Power-over-Ethernet Controller enables remote powering of terminal equipment such as IP telephones, WLAN access points and security cameras via Ethernet.

IP telephony, also known as voice over IP (VOIP), has been an unparalleled success. It enables the transmission of voice signals via conventional, structured Ethernet cabling.

The extension of existing infrastructures with radio networks (WLAN) is also experiencing a substantial upturn. However, both telephones and WLAN access points must be supplied with power from low-voltage supply units, which is a disadvantage since this has always meant having to ensure that there is a 230-Volt socket in immediate proximity to the installation location. That is not the only problem: if the supply unit fails - regardless of whether this is due to a defect or a power cut - the terminal equipment also stops working.

ADC KRONE is now presenting a practical solution for the direct supply of power to this (and other) equipment, which will render supply units superfluous: the TrueNet Midspan Power-over-Ethernet Controller.

"ADC KRONE`s new PoE offering eliminates the previous drawback by powering PoE-compatible terminal equipment directly via Ethernet cabling in accordance with the Power-over-Ethernet standard IEEE 802.3af," said Matthew Palmer, Product Manager Enterprise Actives, ADC KRONE. "Using the TrueNet Midspan PoE Controller, it is possible, for example, to install WLAN access points in previously inaccessible places. This means that companies benefit not only from simplified installation but also from an improved WLAN range."

A patent-pending solution, each midspan PoE controller can be equipped with a redundant power supply and can power up to 24 devices via Ethernet - all with an installation height of just 1U! What distinguishes this product from others is its flexibility: the supply voltage is fed directly in through the floor distributor switch cabinet by simply patching cables between the Ethernet switch, the midspan PoE controller and the RJ45 port in the distribution panel.

The distance to the terminal equipment can be up to 100 metres in accordance with the Ethernet standard. Uninterrupted power supply (UPS) in the floor distributor also enables IP telephones and security cameras to switch over to emergency operation in the event of a power cut.

With its engineered dual-compliance function, the TrueNet Midspan Controller can also power popular Cisco devices that do not conform to 802.3af. These products were already on the market before the specification of the PoE standard. What is very important is that, due to its integrated power-sensing function, the TrueNet Midspan Controller automatically detects whether or not the connected equipment is PoE-compatible. If no power supply is required, the controller does not feed in any power, which ensures that the connected devices are not damaged.

SNMP modules are available for the TrueNet Midspan PoE Controller. These cards that can be inserted into the back of the devices enable remote monitoring and management of the PoE controller via the "Simple Network Management Protocol". Each module can manage up to five linked midspan controllers via just one IP address. This also enables the specific hard-reset of individual terminal devices from a central point.
