Power over Ethernet Solutions
Table 3-1: Troubleshooting Steps
1.
Verify that a known-good power cord is used.
2.
Verify that the voltage at the power inlet is between 100 and 240 Vac.
3.
Remove and re-apply power to the device and check the indicators
during power up sequence as described in Para. 3.7.
1. The Midspan did not detect a PD and therefore the port is not enabled.
2. Verify that the PD is designed for Power over Ethernet operation.
3. Verify that 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 known-good
splitter.
5. Verify that the PD is connected to the Data & Power output port.
6. Try to reconnect the same PD to a different port on the same or into
another Midspan. If it works, there is probably a faulty output port or
RJ-45 connection.
7. Verify that port shutdown command was not issued via the Web
manaegment.
