Connecting Cables
This section describes how to connect your Cisco MWR 1941-DC-A router to external devices and
networks. It includes the following sections:
•
Connecting the Console (Terminal) and Auxiliary (Modem) Ports, page 3-8
•
Connecting the Network Cables, page 3-10
Connecting the Console (Terminal) and Auxiliary (Modem) Ports
Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1001
Your Cisco MWR 1941-DC-A router has a DCE-mode console port for connecting a console terminal,
and a DTE-mode auxiliary port for connecting a modem or other DCE device (such as, a CSU/DSU or
other router) to your router.
Note
Both the console and auxiliary ports are asynchronous serial ports; any devices connected to these ports
must be cabled for asynchronous transmission. (Asynchronous is the most common type of serial device;
for example, most modems are asynchronous devices.)
The Cisco MWR 1941-DC-A router uses RJ-45 ports for both the auxiliary port and console port.
