SFP module on HP 1910-8G

Hello,

I got HP 1910-8G switch and SFP module. When I insert SFP module console gives these lines and no communication runs thru fiber:

%Apr 26 14:54:59:226 2000 APPANSW00 OPTMOD/4/MODULE_IN:
GigabitEthernet1/0/9: The transceiver is 1000_BASE_SX_SFP

Is this SFP problem? Misconfiguration or SPF ports on switch are broken?
