Symptom
Corrective Steps
Midspan does not
power up
1. Make sure power cord is properly connected.
2. Verify voltage at power inlet is between 100 and
240 VAC.
3. Remove and reapply power to device and check
indicators during power up sequence.
A port indicator is
not lit and
corresponding
PD does not
operate.
1. Verify port is enabled (Midspan did not detect a
PD).
2. Verify PD is designed for Power over Ethernet
operation.
3. Verify you are using a standard Category 5/5e/6,
straight-wired cable, with four pairs.
4. If an external power splitter is in use, replace it
with a viable splitter.
5. Verify PD is connected to DATA & POWER
OUTPUT port.
6. Try to reconnect the same PD to a different port
on the same Midspan or on another one. If it works,
there is probably a faulty output port or RJ-45
connection.
7. Verify port shutdown command was not issued
via Web management.
