Installing the Interface Module
Note Before installing the interface module, read the Activating or Deactivating Interface Module section
in the Cisco ASR 920 Series Aggregation Services Router Configuration Guide.
Step 1 Before inserting an interface module, make sure that the chassis is grounded.
Step 2 If present, remove the blank filler plate covering the interface module slot. To remove, pull the blank
filler plate completely out of the router slot using the captive screws.
Step 3 To insert the interface module, carefully align the edges of the interface module between the upper and
lower edges of the interface module slot in the router.
Step 4 Carefully slide the interface module into the router slot until the interface module makes contact with
the backplane. Figure 3-14 shows how to install the interface module on Cisco ASR-920-24SZ-IM
Router.
