3.8.2Troubleshooting Guide

This paragraph provides a symptom and resolution sequence in order to assist in the troubleshooting of minor operating problems. If the steps given do not solve your problem, do not hesitate to call your local dealer for further assistance. Refer to Table 3-1.

Table 3-1: Troubleshooting Steps

Symptom

Midspan does not power up

A port indicator is not lit and the corresponding PD does not operate.

Corrective 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.
