Setup
Setup of the DWL-P1012 can be completed easily by following these steps:
±
Install the Midspan on a sturdy, level surface that can support at least
6.6 lb. (3 kg) of weight. Do not place heavy objects on the device.
±
The power outlet should be within 1.82 meters (6 feet) of the device.
±
Visually inspect the power cord and see that it is fully secured to the
AC power port.
±
Make sure that there is proper heat dissipation from and adequate
ventilation around the Midspan. Leave at least 4 inches (10 cm) of
space at the front and rear of the Midspan for ventilation
±
Install the Midspan in a fairly cool and dry place for the acceptable
temperature and humidity operating ranges.
±
Install the Midspan in a site free from strong electromagnetic field
generators (such as motors), vibration, dust, and direct exposure to
sunlight.
When installing the Midspan on a level surface, attach the rubber feet to the
bottom of the device. The rubber feet cushion the Midspan, protect the casing
from scratches and prevent it from scratching other surfaces.
Installing the DWL-P1012 on a Desktop
When installing the DWL-P1012 on a desktop or shelf, the rubber feet included
with the DWL-P1012 should first be attached. Attach these cushioning feet on
the bottom at each corner of the device. Allow enough ventilation space
between the DWL-P1012 and any other objects in the vicinity.

Connecting Network Cables
As shown below, 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. The
Management port may be connected directly or through a LAN to the
Management station.
