Module Slots

The router has four module slots to support installation of up to four compatible Cisco Connected Grid
modules, for additional router WAN and NAN interfaces. Modules should be installed in the slots
according to the module slot numbers shown in
section on page
and configuration guide for each module at:
Module Numbering
The system software uses a module numbering scheme to identify router components, including the
modules. Some system software commands refer to module numbers. The numbers refer to the following
router hardware components:
