Setting up hot swap timing Modules have a set of numbered sources that control the operation of timed hot swaps There are two types of sources timed sources and special sources Special sources always perform the same action and have no settings Timed sources have parameters that must be set up in advance When you want to perform a timed hot swap event you must setup the timed sources then assign each signal to a source If multiple signals are assigned to the same source then they will be switched in exactly the same way Finally a command is issued to begin the hot swap event The table below shows an example set of sources some modules have different source configurations that will be listed in their technical manual Source Number Description Signals are always off Timed source 1 Timed Source 2 Timed Source 3 Timed Source 4 Timed Source 5 Timed Source 6 Signals change instantly at the start of the timed event DU A Signals assigned to this source are always connected The timed sources of most modules require one initial delay and three pin bounce parameters The diagram below shows how these parameters affect the state the source after the hot swap begins Any signals that are assigned to this source would connect and disconnect in exactly the same pattern Choosing which signals to switch Control Modules have a link between each pin on one side to the matching pin on the other Some of these
