Introduction to Cisco Network Module Form Factors

Extended single-wide network modules are installed in configurable network module slots on the
Cisco 2821, Cisco 2851, and Cisco 3800 series routers. Extended single-wide network modules cannot
be installed in Cisco 2600 series, Cisco 3600 series, Cisco 3700 series and Cisco MWR 1941-DC
routers. See
Figure 1-2
Double-wide network modules require the removal of the right side panel for installation in the top slot
of the Cisco 3725 router, because the bottom slot only supports single-wide modules. On the Cisco 3745
router, the double-wide network module occupies two single-wide slots and is supported by removing
the midwall divider. On Cisco 2851 and Cisco 3800 series routers, network module slots must be set up
properly before double-wide network modules can be installed. See

Extended double-wide network modules are supported only on the Cisco 2851 and Cisco 3800 series
routers. Extended double-wide network modules occupy two extended single-wide network module
slots, which must be set up properly before extended double-wide network modules can be installed. See
