potential.
The Cell Interface also accepts power from its Link In connector to power itself, as well as subsequent
Cell Interface modules in the Link Bus chain (i.e. connected to its Link Out connector). The amount of
current sourced into this connector is the sum of current consumed by this Cell Interface and the
subsequent Cell Interface modules in the Link Bus chain.

This interface is used to provide a data channel and power source to subsequent Cell Interface
modules in the Link Bus chain. The amount of current supplied by this connector is the sum of current
consumed by all subsequent Cell Interface modules in the Link Bus chain (up to 25 mA per CI-12 or
