PoE bounce cold starts a WS-6-MINI

[lligetfa]

Twice now I had a camera on port 5 go down (no link state) so I issued a PoE bounce. Each time I lost connection to the switch and when I reconnect, the log indicates a cold start. As a test, even when port 5 was not down, a PoE bounce bounced the entire switch and then the cam on port 5 did not come back online. As another test, bouncing port 3 did not bounce the entire switch.

Firmware = 1.5.5
Total power draw < 30w
Voltage (drop) from the 48VH fed from WS-24 = 44.5V
Port 5 = 24V

Does this happen on any of the other ports besides 5 on the WS-6-MINI?

The only other port I tried it on was port 3 and the problem did not manifest.

Last night we had the power go out and now the MINI is stuck in a boot loop. It won't stay up long enough for me to log in. I will have to try unplugging ports to see if I can get it to stop rebooting.

I went to investigate on site. Switch stays up if I shed all PoE load. It might stay up if I add only one PoE load depending on what the draw is on the one I add.

This sick MINI was powering a second MINI further downstream. The second MINI is a very old prototype that had only one cam on it. I swapped the two MINIs around so that the sick one is furthest downstream and powering only one G3-Flex cam. It is staying up at this point. The prototype is carrying the full load that the sick one was powering so that seems to rule out the cameras as culprits.
