Power over LAN Solutions 7 Cat. No.: 06-6831-056
2 About the Power over LAN Midspan PowerDsine’s family of Power over LAN Midspans, series 3000, injects power
over data-carrying Ethernet cabling. The PD-3006/3012 Midspans, support 6
and 12 ports respectively in a 10/100BaseTx Ethernet network, over TIA/EIA-
568 Category 5/5e/6 cabling. The DC operating power for the 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 splitter in order to be powered.
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)
* Power management for PD-3012 only
* Independent overload and short-circuit protection per channel
* Port status indications
* Optional 19-inch rack kit.
2.1 Power Management (PD-3012 only)
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 (92 W). 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 port 12 down until the total power is once again under the
maximum limit.
