operates, but there is
no data link.
Is it safe to keep the
Midspan running while
a port indicator is
orange?

Table 4-1: Troubleshooting Steps
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 viable splitter.
3. 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
link is 100 m or less.
4. Try to re-connect the same PD to a different port on the same
midspan or to a different unit: if it works, there is probably a faulty
port or faulty RJ-45 connection.
This is a safe condition. The orange indication is due to:
1. A device not compliant to IEEE 802.3af, is detected.
2. Terminals 4/5 and 7/8 are shorted together.
3. Forced external power fed into the port.
During these conditions, port power is disconnected.
