Help on OOBE and A1-A2, B1-B2 interface ports - HP-2920

[Stevep3577]

Hi All 

I need to remove a switch and re-configure for another location. However it means repatching some servers which should'nt be an propblem but i have discovered something on the config i dont understand. Below is the config, just need some info on the ports A1-A2 and B1-B2 which are untagged on vlan 1. Are these some sort of virtual ports, other type of interface ports or related to OOBE? greatful for any help. Thanks

Ports A1-A2, B1-B2 are modular 10Gig ports in the back of the switch.
