Installing the Power over LAN Midspan
3.1
Background Information
As shown in Figure 3-1, the Midspan is connected in series to an Ethernet
switch/Hub. The data outputs from the switch are connected to the Midspan.
The Midspan delivers power over spare twisted pairs (pins 7/8 and pins 4/5) of
the Category 5 cabling without degrading the quality of data communications.
3.2
Connecting Cables
The ports on the front panel of the Midspan are configured as "route through"
ports for all eight conductors of the RJ-45 connectors. Use Category 5 cabling
in making connections.
1. Connect cables from the Ethernet Switch to the Data ports (bottom
row on Midspan).
2. Connect the cables from the IEEE 802.3af ready terminals (PDs) to
the corresponding Data & Power ports (top row on Midspan).
