4 Summary

The hot-swapping and hot-insertion technologies have raised the level of system availability with zero-downtime support. Therefore, it is possible to have a system that might never need to be shut down for maintenance. These new hardware designs have built-in redundancy and, at the same time, provision for upgrades. Our bus switches can be used as a design for inserting multiplexes into live systems up to level 2 of isolation.
