Midspan does not power up | - Verify that a power cord known to be in order is used.
- Verify that the voltage at the power inlet is between 100 and 240 VAC.
- Remove and re-apply power to the device and check the indicators during the power up sequence.
|
A port indicator is not lit and the PD does not operate | - The Midspan did not detect a PD and therefore the port is not enabled.
- Verify that the PD is designed for PoE operation.
- Verify that you are using a standard CAT 5/5e/6, straight-wired cable, with four pairs.
- If an external power splitter is in use, replace it with a verified good splitter.
- Ensure that the input Ethernet cable is connected to the Data-In port.
- Verify that the PD is connected to the Data and
Power port.
- Try to reconnect the same PD into a different Midspan. If it works, there is probably a faulty port or RJ45 connection.
- Verify that there is no short-circuit over any of the twisted pair cables or over the RJ45 connectors.
|
The end device operates, but there is no data link | - Verify that the port indicator on the front panel is continuously lit.
- If an external power splitter is in use, replace it with a verified good splitter.
- Verify that you are using a standard straight-wired four-pairs cable (UTP/FTP Category 5/5e/6).
- Verify that the Ethernet cable length is less than 100 meters from the Ethernet source to the load/remote terminal.
- Ensure that the input Ethernet cable is connected to the PoE Midspan "DATA IN" port.
- Try to reconnect the same PD into a different Midspan. If it works, there is probably a faulty port or RJ45 connection.
