Auxiliary Connection
• To reduce the chance of interference, avoid crossing high-power lines with any interface cables.
• Verify all cabling limitations (particularly distance) before powering on the system.
Auxiliary Connection
This asynchronous EIA/TIA-232 serial port (AUX) is used to connect a modem to the Cisco ASR 1000 
Series Route Processor 1 for remote administrative access. Use the following procedure to connect the 
Cisco ASR 1004 Router to a modem.
Step 1 Connect one end of the modem cable to the RJ-45 port on the primary Cisco ASR 1000 Series Route 
Processor 1, labeled AUX.
Figure 7-23 shows the route processor auxiliary connector.

Run the cable up and through the cable-management bracket and connect the other end of the cable to 
your modem.
If you have completed all cable connections, go to Chapter 12, “Cisco ASR 1000 Series Routers Power
