Actually, they are not called CB but Computer Reset Button, there is one per side, and are located on the over head panel.
Regarding the Airbus procedure, if the problem is limited to a cracked windshield, there won't be any associated ECAM Message, pilots will go straight to the Quick Reference Handbook,
then they can find more information in their FCOM 3, and it doesn't hurt if they open the MEL especially if they have 10 more hours to go.
The limitation is on the differential pressure, but there is no restriction to proceed to destination ... if fuel permits !
