2. Installation
The output module always resides in the allocated I/O module slot (position) within the Trusted TM
Controller or Expander Chassis. These module positions are keyed for T8449 modules to prevent
installation of the incorrect module type. Other module positions are keyed to match their intended
module type. The output module must NOT be installed in other module locations, as this may cause
damage to the module.
