2 About the Power over LAN Midspan

PowerDsine’s family of Power over LAN Midspans, series 6000, injects power over data-carrying Ethernet cabling. The PD-6006/6012/6024 Midspans, support 6, 12 and 24 ports respectively in a 10/100BaseTx Ethernet network, over TIA/EIA-568 Category 5/5e/6 cabling. DC operating power, for data terminal units, is fed over unused pairs of the cabling (7/8 and 4/5).

The Power over LAN Midspan normally powers devices that are Power over LAN enabled or are equipped to receive power over Ethernet. These devices are called Powered Devices (PDs). Devices that are not equipped to receive power over Ethernet may require an external power adapter in order to be powered. Contact PowerDsine for such an adapter.

Power over LAN Midspan main features:

Remote power feeding of Ethernet terminals

Eliminates the need for AC outlets, local UPS and AC/DC adapters

Universal range power input (100-240 VAC, 50/60 Hz and/or 46 to 57 VDC)

Power management

SNMP management (optional)

Independent overload and short-circuit protection per channel Port status indications

Standard 19-inch rack mountable.

2.1Power Management

When establishing a network, the total power required by PDs may exceed the total power available from the Midspan. The built-in Power Management feature will not allow the total power output to exceed the maximum power available (refer to the Technical Specifications). When the total power available is near maximum, attempts to connect an additional PD to a free port will cause the corresponding LED of the port to blink orange, indicating an out- of-power budget. This port will not deliver power. Power distribution is based on “first come, first served” logic.

It is possible that connected and operating PDs will significantly increase or suddenly raise their power requirements. If the power required exceeds the power available, the Power over LAN Midspan will start to turn off ports, starting from the last port down, until the total power is once again under the maximum limit.
