3.5. Bypass Functionality
The bypass functionality secures connection backbone traffic in case of power failure by
bridging the two pairs of ports normally connected to the backbone.
The ports are cross-coupled when in bypass. This is since the main use cases require the
use of fixed MDI/MDIX settings. During power loss and connection of the two adjacent
switches, the intent is to compensate for the fixed MDI/MDIX settings.
