Connecting two SG500X-48's through XG1 on both sides with fiber. When I plug in the connector, the link light blinks rapidly a couple times (varies) then stops and goes dark. No connection, interface status is down.
I've ran down the obvious so far. Fiber cable is good, and switches are in standalone mode.
I'm mainly curious why the link light blinks then stops? Does this indicate a specific issue? (auto-neg failure, etc.)
I've searched for what this means, if anything, and came up empty.
