Connecting Ethernet 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).
3.4
Connecting Power Cables
When using AC to power the Midspan, plug in the power cord supplied, at the
rear AC connector. If DC is to be used (as primary or back-up power), connect
the DC primary wiring to a Molex P/N 44441-2002 connector, with 2 Molex
terminals P/N 4330-75/0001. Pin 1 is the positive polarity of the DC connector,
at the rear of the chassis.
3.5
Powering up
The Power over LAN Midspan has no on/off switch. To apply or remove power
to the Midspan, insert or remove the power cable from the receptacle(AC
and/or DC) on the rear panel of the unit.
With power applied, the Midspan powers-up and the internal fan operates;
then, the device runs through its power-on self-test (POST), which takes less
than 10 seconds. During the POST, all ports are disabled and the indicators
illuminate in the following sequence:
1. Port indicators and power indicators (AC & DC) illuminate green.
2. Port indicators and the AC indicator illuminate orange.
3. Main (AC or DC) indicator remains lit green; port indicators are out.
Ports are now enabled for normal operation.

Troubleshooting
3.6.1
Preliminary Steps
If you encounter problems, check that:
Power is applied to the Midspan
A crossover-type Ethernet cable has not been used
The Ethernet cable from the network is connected to the Data port
The Ethernet cable to the PD is connected to the Data & Power port
Cable pairs are attached to corresponding ports.
