Why can't I enable port 3 (fiber SFP port on a T710s AP?

[tim_kennedy_fxl]

We have a T710s Access point. Connected directly to certified fiber. We have a ZD 1200 that could not see the AP. I logged into the ZD to manually assign it an IP address on same subnet.

When I try to enable port 3-which is the Fiber port-the settings take, but when I log back in, the GUI tells me the port is disabled. Any ideas?

Please contact your local VAR you got the T710s from, for assistance connecting your SFP optic module to the fiber port.
And please note the recommended connectors from the QSG:
