2. Referring to examples of modules shown in Figure 5-5 and Figure 5-6 secure the modules to the backplane by:
Closing the ejectors (for relevant modules)
Tightening the captive screws
Note: Modules with ejectors (i.e. RIM, RIX and HCM/ACM) the ejectors should be completely open when inserting in
dedicated slot and then push in until the module clicks in to the backplane. Figure 5-5 and Figure 5-6 show examples of
