Module Installation

All modules can be installed and removed as shown in Figures 2-15and 2-16.Exercise caution when installing or removing modules. If you have difficulty installing or removing a module, check the module for alignment problems. Inspect the carrier channel for damage. If no damage is present, the modules should snap into place.

NOTE: Do not install or remove modules with the power on unless the system has the On-Line Module Swap feature, available only with Release 3. The Processor Module and Power Supply Module cannot be removed using this procedure. Refer to
