Cisco 3200 WMIC Image Upload Procedure
This section provides the procedures for configuring a Cisco 3200 Series router (referred to as the
Mobile Access Router Card (MARC)) as a TFTP server and uploading a Cisco IOS image to the router
and two WMICs enclosed with the router. The major advantage of this procedure is that all the cards in
the router receive the same version of the Cisco IOS image to avoid conflicts when the devices
communicate.
Overview
The Cisco 3200 Series router is actually a stack of devices contained in an enclosure that can include
multiple devices that process data from the network independently. For example, a Cisco 3200 Series
router with two WMICs is actually three devices in one enclosure; one router, consisting of a MARC and
possibly a Fast Ethernet Switch Mobile Interface Card (FESMIC) and/or a Serial Mobile Interface Card
(SMIC), and two WMICS.
The MARC communicates with a FESMIC or a SMIC through the internal PCI bus. The FESMIC and
the SMIC depend on the MARC to process the data that the FESMIC or SMIC send and receive. As a
result, FESMIC and SMIC cards are seen by the MARC as expansion cards, similar to the way in which
a modular Cisco router increases functionality with the addition of expansion modules. The cards
physically and logically become part of the router.
Each WMIC has an on-board CPU that processes data it sends and receives independent of the MARC.
The WMICs draw power from the internal bus; they do not use the bus to communicate with the other
devices in the stack. The WMICs communicate with the router by using the switched Fast Ethernet ports
and the routed Fast Ethernet port to create a small, internal Ethernet network. As a result, each WMIC
must store a copy of the Cisco IOS image in its memory and be configured independently.
To avoid conflicts, we recommend that you upload the same image to all of the devices (CPUs) in the
enclosure by configuring the router as a TFTP server that can serve the Cisco IOS image to the WMICs.
The following major steps are required to upload the Cisco IOS image to all the devices in a Cisco 3200
Series router stack.
Configure the router as shown in the
Step 1
connectivity to a TFTP server.
To copy the image to the MARC, use the copy tftp flash:tarfilename command.
Step 2
Enter the tftp-server flash:tarfilename command to configure the MARC as a TFTP server, making the
Step 3
image available to the WMICs.
Configure router for IP connectivity to all of the WMICs. Examples are provided in the
Step 4

Upload the new image to the WMICs, for example:
Step 5
Step 6
To verify that the new image is in place, use the show version command.
