Troubleshooting
Symptom | Corrective steps | |
|
|
|
Midspan does not power up | 1. | Verify that an approved power cable is used. |
| 2. | Verify that the voltage at the power inlet is between 100 and |
|
| 240V AC. |
| 3. | Remove and |
|
| indicators during power up sequence. |
|
|
|
A port indicator is not lit and the PD | 1. | The Midspan did not detect a PD; and the port is not enabled. |
(powered device) does not operate | 2. | Verify that the PD is designed for PoE operation. |
| 3. | Verify that you are using a standard Category 5/5e/6, straight- |
|
| wired cable, with four pairs. |
| 4. | If there is an external PoE device is connected, replace it to verify |
|
| that it is functioning properly. |
| 5. | Ensure that the input Ethernet cable is connected to the Data In |
|
| port. |
| 6. | Verify that the PD is connected to the Data & Power port. |
| 7. | Try to reconnect the same PD into a different Midspan. If it works, |
|
| there is probably a faulty port or |
| 8. | Verify that there is no shortcut over any of the twisted pair cables |
|
| or over the RJ45 connectors. |
|
|
|
The end device operates, but there is | 1. | Verify that the port indicator on the front panel is continuously |
no data link |
| lit. |
| 2. | If an external PoE device is in use, replace it with a known good |
|
| PoE device. |
| 3. | Verify that for this link, you are using standard UTP/FTP Category |
|
| 5 straight |
| 4. | Verify that the Ethernet cable length is less than 100 meters (333 |
|
| feet) from the Ethernet source to the powered device. |
| 5. | Try to reconnect the same PD into a different Midspan. If it works, |
|
| there is probably a faulty port or |
