3630sm flashing port light on 24v power adapter

I have a few radios with the flashing port light on 24v power adapter problem,(it is not the power adapter) cannot login will not give me a valid gateway address. anyone have a fix for this?

bad suppressor, test with a couple and replace if surge if it works with the coupler…

we have had a few of these, putting a new surge in took care of the problem. The 3630 is a 48v (802.11 af standard) supply, the older surge suppressors trip on these. you can also power the 3630 CPE with a standard POE switch.
