Complete the following steps to install the application modules in the host module.
1 Align the ridges on the top and bottom of the module with the guide slots
located on the host module and the chassis. Be careful to keep the module level
as you slide it into the host to avoid bending the pins on the host back plane.
2 Gently slide the module into the host module until you feel the power and
communications connections on the back of the module join connectors on the
host module. Use the thumbscrew on the top of the module to lock it in place.
