| PD-9601GS does not power-up. | - Verify that a reliable power cord is used.
- Verify that the voltage at the power inlet is between 100–240 VAC.
- Remove and reapply power to the device and check the indicators during the power-up sequence.
|
| The PD does not operate. | - Verify that the PD-9601GS Midspan detects a PD.
- Verify that the PD is designed for PoE operation.
- Verify that the cable used is a standard Category 5/5e/6, straight‑wired cable, with four pairs.
- If an external power splitter is in use, replace it with a known-good splitter.
- Ensure that the input Ethernet cable is connected to the DATA IN port.
- Verify that the PD is connected to the DATA & POWER port.
- Reconnect the same PD to a different PD-9601GS. If it works, there is probably a faulty port or RJ45 connection.
- Verify that there is no short 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 known-good splitter.
- Verify that for this link, you are using a standard UTP/FTP Category 5 straight (non-crossover) cabling, with all four pairs.
- Verify that the Ethernet cable length is less than 100 meters from the Ethernet source to the load/remote terminal.
- Reconnect the same PD to a different PD-9601GS. If it works, there is probably a faulty port or RJ45 connection.
