S248DF - Upgrade to 3.6.12 Shows Offline

[cql-user-01]

After upgrading my 248DF to 3.6.12, the unit is online and active, but shows offline and I cannot connect to it through fabric.  I removed power for 15 sec and plugged back in and still shows offline.  Suggestions?

Thanks for the reply, I did go through this document and I do not get the warning about hte NTP : "WARNING : NTP service for DHCP entry should be set to local mode .... please check config <-- (It is necessary to change the ntp server to 'local' in the FortiLink interface.)"

I CAN ping the interface, so I know I'm connected on the Fortilink.  Any other suggestions?
