Installing Network Modules and Interface Cards
Cisco routers are normally shipped with network modules, voice and WAN interface cards (VWICs), and WAN interface cards (WICs) already installed. If you need to remove or install any of these items, refer to the applicable documents online.
For network modules:
•
•
For VWICs:
•
For WICs:
•
•
If there are modules, interface cards, or power supplies to be removed or installed, Cisco suggests that you perform the installation or removal before you install the chassis. If a chassis cover needs to be removed, the chassis may have to be removed from the rack to permit cover removal.
Rack Mounting the Chassis
You can mount the Cisco MWR 1941-DC router in a 19-inch rack that conforms to EIA-310-D specification (the inside width of the rack should be 17.72 to 17.80 inches per the EIA-310-D specification). The MWR 1941-DC router requires this minimum width and occupies 1U (1.75 inches) of vertical space.

Attaching the Brackets
Attach the mounting brackets to the chassis as shown, using the screws provided in the bracket kit. Attach the second bracket to the opposite side of the chassis. Use a number 2 Phillips screwdriver to install the bracket screws.
Three screws are required on each side. Figure 3-1 shows how the bracket is attached.
Figure 3-1 Attaching the Bracket
Installing the Router in the Rack
Install the chassis in the rack. Rack-mounting screws are not provided with the router. Use three screws for each side (supplied with the rack).
Connecting the Console Terminal and Modem
This section describes how to connect a console terminal and a modem to the router. You can connect only a terminal to the console port. Use the auxiliary port with a terminal or a modem for remote access to the router.
These ports provide administrative access to your router either locally (with a console terminal) or remotely (with a modem).
Identifying a Rollover Cable
Use a rollover cable to connect to the asynchronous serial console and auxiliary ports. You can identify a rollover cable by comparing the two modular ends of the cable. Holding the cables side-by-side, with the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. (See Figure 3-2.) If your cable came from Cisco, pin 1 will be white on one connector, and pin 8 will be white on the other (a rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).

Connecting the VWIC Interface Cables
How you connect the ports of the T1/E1 Multiflex VWIC depends on whether you are using the MWR 1941-DC router in a redundant (IP-RAN implementations only) or a non-redundant configuration.
For redundant configurations, use a Y-cable (as described in Y-Cable Specifications).

Y-Cable Specifications
Although it can be used in a standalone MWR 1941-DC router, the T1/E1 Multiflex VWIC is designed to be used in redundant configurations in an IP-RAN implementation. Such configurations require a special Y-cable for connecting the active and standby routers. The Y-cable provides a dual E1 or T1 PRI connection.
This section describes the specifications of the Y-cable used in redundant configurations in an IP-RAN implementation.

Connecting the WIC-2A/S Interface Cables
This section describes how to connect the 2-port asynchronous/synchronous (A/S) serial modules (WIC-2A/S) when using with the MWR 1941-DC router in a Cell Site DCN implementation.
The 2-port A/S serial module has "smart" serial ports. The serial cable attached to one of the module's ports can determine the electrical interface type and mode (DTE or DCE).
Six types of serial cables (also called serial adapter cables or serial transition cables) are available from Cisco Systems for use with the 2-port A/S serial module:
•
•
•
•
•
•
All serial cables have a universal plug at the interface module end. The network end of each cable provides the physical connectors that are most commonly used for the interface. For example, the network end of the EIA/TIA-232 serial cable is a DB-25 connector, which is the most widely used EIA/TIA-232 connector.
All serial interface types, except EIA-530, are available in DTE or DCE mode: DTE with a plug connector at the network end and DCE with a receptacle at the network end. The V.35 assembly is available in either mode with either gender at the network end. The EIA/TIA-530 assembly is available in DTE only.
After you install the 2-port A/S serial module, use the appropriate serial cable to connect the serial port on the module to one of the following types of equipment (see Figure 3-5):

Formatting Procedures for CF Memory Cards
For the Cisco MWR 1941-DC router, Cisco recommends that you format/erase new CF memory cards to initialize them with a Class C Flash file system. This ensures proper formatting and enables the ROM monitor to recognize and boot the Flash.
The Class C Flash file system is similar to the standard DOS file system; however, a CF memory card formatted with the standard DOS file system does not support booting from the ROM monitor.
Formatting CF Memory as a DOS File System
To format a new external CF memory card, or to remove the files from a previously installed external CF memory card, enter the format slot0: command.
The following example shows output for formatting a CF memory card formatted with a Class C Flash file system:
Router# format slot0:Format operation may take a while. Continue? [confirm]Format operation will destroy all data in "slot0:". Continue? [confirm]Enter volume ID (up to 64 chars)[default slot0]:Current Low End File System flash card in flash will be formatted into DOSFile System flash card! Continue? [confirm]Format:Drive communication & 1st Sector Write OK...Writing Monlib sectors ...................................................................Monlib write complete..Format:All system sectors written. OK...Format:Total sectors in formatted partition:250592Format:Total bytes in formatted partition:128303104Format:Operation completed successfully.Format of flash completeFile and Directory Procedures
The following sections describe file and directory procedures for external CF memory cards formatted with a Class C Flash file system.
Copy Files
To copy the files to another location, use the copy slot0: source-filename { slot0: | tfp: | lex: | null: | nvram: | pram: | rcp: | system: | tftp: | xmodem: | ymodem: | running-config | startup-config} destination-filename command.
The following example shows output for copying a Cisco IOS file from an external CF memory card to a TFTP server:
