CM600

I just bought this router yesterday. I called my ISP to register it. Everything seems to be working fine. It's just the Ethernet LED light keeps flashing. Firmware is 1.01.14. When I login into the router, I see that in the column upstream there are 4 entries that are still unlocked. I believe that is the reason for the flashing. But it doesn't seem to affect much. Internet is working. Speeds are correct. But those 4 values are not locked. Is this something to worry about. If so, is there any fix. Thanks
