How Autoconfiguration Handles Equipment Changes
Previously-configured modules are not removed from the configuration during
autoconfiguration unless no modules are present in the system during the
autoconfiguration.
Module Present But Non-Working During Autoconfiguration: if a module is
physically present but not working during autoconfiguration, the module is not
configured and the NIU generates an extra module diagnostic.
Empty Slot During Autoconfiguration : Autoconfiguration stops at the first empty slot.
Modules located after the empty slot are not autoconfigured. The NIU generates an
extra module diagnostic for each of them.
If a module that was not previously-configured or present at powerup is installed-
after powerup, the NIU generates an extra module diagnostic and the module is not
added to the system configuration.
Previously-Configured Modules Not Present During Autoconfiguration: Previously-
configured modules are not removed from the configuration during
autoconfiguration unless no modules are present in the system. For example, if
modules are configured in slots 1, 2, and 3 then power is removed and the module in
slot 1 is removed, when power is reapplied the modules in slots 2 and 3 operate
normally. The original module in slot 1 is not removed from the configuration. The
NIU generates a loss of module diagnostic for slot 1.
Different Module Present During Autoconfiguration: If a slot was previously-
configured for one module type but has a different module installed during
autoconfiguration, the NIU generates a configuration mismatch diagnostic. The slot
remains configured for the original module type.
Unconfigured Module Installed After Autoconfiguration : If a module that was not
previously-configured is installed-after powerup, the NIU generates an extra
module diagnostic and the module is not added to the configuration.
Previously-configured Module Installed After Autoconfiguration : If a module that was
previously-configured but missing at powerup is installed after powerup, the NIU
generates an addition of module diagnostic and the module is added back into the
I/O scan.
All Modules Removed After Autoconfiguration: If all modules are absent at powerup,
the NIU clears the configuration. This allows modules to be inserted and added to
the configuration at the next powerup.
