Chapter 5 Connecting Serial Network Modules
32-port asynchronous module, or some other type of module—or even whether there is a network
module in slot 0 at all. If you move the module in slot 1 to a different slot, however, its interface numbers
change.
The Cisco MWR 1941-DC router has one network module slot (slot 1).

Cisco 2600 Series and Cisco MWR 1941-DC Router Serial Interface Numbering
Interface numbering for Cisco 2600 series and Cisco MWR 1941-DC routers differ from Cisco 3600
series interface numbering in the following ways:

WAN interface card slot numbers always appear as slot 0, even if the interface card is installed in
the slot labeled W1.
WAN interface cards are numbered dynamically, starting with the first card installed. For example:
If slot W0 is empty and slot W1 contains a 1-port serial WAN interface card, the interface
–
number is serial 0/0.
If slot W0 contains a 2-port serial WAN interface card and slot W1 contains a 1-port serial
–
interface card, serial 0/0 and 0/1 reside in slot W0 and serial 0/2 resides in slot W1.
