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.
2.1. Module Insertion/Removal
CAUTION:
The module contains static sensitive parts. static handling precautions must be observed. Specifically
ensure that exposed connector pins ARE NOT TOUCHED. Under no circumstances should the
module housing BE REMOVED.
Before installation, visually inspect the module for damage. Ensure that the module housing appears
undamaged and inspect the I/O connector at the back of the module for bent pins. If the module
appears damaged or any pins are bent, do not install the module. Do not try to straighten bent pins.
Return the module for replacement.

2. If I/O module keys are used, verify that all keys are installed in the correct positions and
properly seated in their slots.
