Module Installation
All modules can be installed and removed as shown in
Figures 2-15 and 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
