Hello.
I have 3 7150 12p and all have the same problem: if connected to another Ruckus switch with 1G SFP link is down. But if I connect with another brand everything is OK.
Firmware = 08.0.95a
ICX7150 to ICX7150 = NO OK
ICX7150 to UNIFI US-8-150 = OK
ICX7150 to TP LINK SG2210p = OK
EDGEROUTER TO ICX7150 = OK
