3.6.2 Troubleshooting 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 Corrective Steps
Midspan does not
power up
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.
AC indicator lit
orange
Power-on self-test failed: the Midspan detected an internal
fault. In this case, contact your local dealer.
AC and DC
indicators lit orange
Power-on self-test failed: the Midspan detected an internal
fault. In this case, contact your local dealer.
A port indicator is
not lit and the
corresponding PD
does not operate.
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 LAN
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 port.
6. Try to reconnect the same PD to a different port on the
same or into different Midspan. If it works, there is
probably a faulty port or RJ-45 connection.
The end device
operates, but there
is no data link.
1. Verify that the port indicator on the front panel is
continuously lit.
2. If an external power splitter is in use, replace it with a
known-good splitter.
3. Verify that for this link, you are using standard UTP/FTP
Category 5 straight (non-crossover) cabling, with all four
pairs. Check that the link is 100 m or less.
4. Try to re-connect the same end device into a different
port on the same unit or into different unit – if it works,
there is probably a faulty port or RJ-45 connection.
