Section 2 Installation Installing the CEX-Bus Interconnection Unit BC810/TP857
3BSE036351-510 A 99
Hot swap of the BC810 located next to a primary or single controller CPU,
otherwise called “direct BC810”, might jeopardize the whole controller and
should not be performed unless every module on the CEX-Bus are in a non-
operating state. Note: In an AC 800M HI controller this is unconditionally and
intentionally leading to a shutdown of the controller.
Hot swap of the BC810 not located next to a primary or single controller CPU,
otherwise called “indirect BC810”, will shut down any non-redundant interface
located on that CEX-Bus segment and should not be performed unless such
interfaces already are in a non-operating state or their function is dispensable for
the controller.
