Mid-Span Power over Ethernet Hubs
Enterasys Mid-Span Power Hubs provide a safe and efficient way to power IP phones, wireless LAN access points, security cameras and other LAN devices without using an external power supply for each device.
Power is supplied over the existing LAN data cabling system, greatly improving the range of installation locations for such devices since they no longer need to be located near a power outlet. It also adds an unprecedented level of safety and reliability for powered LAN devices.
The Enterasys BL-89000ENT Mid-Span Power Hub is available in 10-slot or 20-slot rackmount chassis that can accommodate up to 10 or 20 individual modules, respectively. Each module is hot-swappable so that modules may be added to the chassis without powering down the unit.
For safety, each module has its own DC-to-DC converter, which is voltage-isolated from the other ports. Each module is separately fused and protected from any unexpected current surge. If a power surge should occur, either through a building electrical system or lightning strike, the Mid-Span Power Hubs take the force and help protect the valuable equipment attached.
If an individual power module is damaged due to misuse or a very large power surge, the unit may be hot swapped without powering down the chassis or disconnecting the devices attached to other power modules in the chassis.
When used with an uninterruptible power supply, the Mid-Span Power Hubs provide non-stop power for up to 10 or 20 connected devices. Continuous operation of powered LAN devices is assured, while costly downtime is avoided. The Mid-Span Power Hubs also eliminate the need to install costly uninterruptible power supplies for each powered LAN device, saving time and money.
The Mid-Span Power Hubs are tailored to provide maximum value in convergence network applications. External power supplies normally required for IP phones become unnecessary. Power is now supplied by the Mid-Span Power Hubs to the phones over the existing LAN cabling infrastructure. A device-detection circuit provides invaluable protection from overvoltage damage when connecting expensive devices, such as IP phones or laptops, to the network.
