High density electronics allows for the function of two machines to be fit into a space that previously could contain but a single machine function. Typically, one AC power supply is provided for the entire system, regardless of the number of machine functions included. Some users require a separate AC power input supply for each machine function to eliminate single points of failure. This need is commonly satisfied by bolting two identical machine frames together and cross- cabling the machines. However, cross-cabled machines cannot be upgraded or serviced without significant down time.
