To install port expansion modules, follow these steps: Step 1 Step 2 Decide if the expansion board is going in the EM0 slot or EM1 slot, as shown in Figure 16-4. Insert the connector on the port expansion module into the module connector on the network module, as shown in Figure 16-4. Use the alignment pins on the bracket to correctly align the expansion module. If the pin does not properly align with the expansion module, the rear bracket can be adjusted by loosening the screw underneath the bracket and tightening it when the module is correctly in place. 16-4 Cisco Network Modules Hardware Installation Guide OL-2485-20
