I have an RB260GSP powered through a 10m ethernet cable @ 24V (the RB260 reads 22.435V on the web interface).
Connected to the RB260 I have one SXT G-2HnD and two Groove A-52HPn. All three of these devices are being powered by the RB260 drawing between 50mA and 200mA. (A persistent graph of power usage would be a VERY nice debug tool).
In order to get the RB260 to power the devices I had to tick the 'PoE In long cable' tick box.
However, periodically, any time from once a week to once a month all three output ports go into 'short circuit' mode and shut off. Only after some random mix of PoE off to the ports and rebooting with my tongue at the right angle and all planets aligned do the ports come back to life again, at which point they'll work for another arbitrary period of time.
The PSU feeding the PoE for the RB260 is a 24V @ 1.25A (30W) PSU.
Has anyone else faced this issue? Can anyone make a suggestion as to what I should try next?
