PowerDsine manual PD-6548 Troubleshooting Steps

Symptom

AC indicator lit orange

Midspan repeatedly shutsdown for few minutes and then starts

The end device operates, but there is no data link.

Midspan port indicator is blinking at a 1 sec. rate

Midspan port indicator is blinking at a 0.5 sec. rate

Corrective Steps

Power-on self-test failed: the Midspan detected an internal fault. In this case, contact your local dealer.

Verify that the ventilation holes are not blocked.

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 another Midspan – if it works, there is probably a faulty input/output port, or RJ-45 connection.

This is a safe condition. The blinking green indication is due to:

1.A device, not compliant to IEEE 802.3af, was 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.

This is a safe condition. The blinking green indication is due to a power management event.

In such event the corresponding port to the indicator, requires power that exceeds power budget capability of the Midspan. During these conditions, port power is disconnected.

A port will operate when total power consumption of the Midspan decreases.

try to connect the PD to another Midspan to verify that the PD is valid.
