Connecting the Console Port to a PC
This document covers tasks associated with connecting a console port to a PC, and includes the following topics:
A console cable kit is provided with your router. Use this kit when connecting your router to a PC or terminal.
The console cable kit contains:
You can identify a rollover cable by comparing the two modular ends of the cable. Hold the cable's ends side-by-side, with the tab at the back (pointing away from you). 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 1.) If your cable came from Cisco Systems, pin 1 is white on one connector, and pin 8 is white on the other (a rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).
The cable and adapters required for this connection are included with the router. Follow these steps to connect the router to a terminal or PC running terminal emulation software:
Step 1 Locate the console port on the back of the router.
Step 2 Connect the console (or rollover) cable to the console port on the router. (See Figure 2.)
Step 3 The console cable will need an RJ-45 to DB-25 adapter for Cisco 4000 and 7000 series routers. This adapter is supplied withthe router and is also included in your verikit.
Step 4 Use the correct adapter to connect the other end of the cable to your terminal or PC.
Step 5 If your terminal or PC has a console port that does not fit one of the adapters, you must provide the correct adapter for that port.
Click on the HyperTerminal icon below to launch a pre-configured HyperTerminal connection. This connection is configured for use with all Cisco routers. (The router should be connected to your laptop at this time. If it is not, see Making the physical connection.)
If you selected the "open" option, you should now be communicating with the router. If you are experiencing problems, make sure the router is powered on, you are attached to the proper Com Port and verify your cabling.
Using this procedure you will create a named connection that you can save and reuse. (This creates a connection identical to the one provided above, and is included primarily for your reference.)
To set up a HyperTerminal connection on your laptop:
Step 1 Click the Start button on the Windows Taskbar, and select. HyperTerminal launches and displays the Connection Description dialog box.
Alternatively, if you previously saved a connection for Cisco equipment, you can launch it by selecting Step 6.). (Proceed to
Step 4 Locate thefield near the bottom of the Phone Number window. Select "Direct to COM1" from the drop-down list to indicate that this connection is a local session (and not a dial-up session). Click . The COM1 Properties window appears.
Step 5 On the Port Settings tab, enter the following settings:
If there are any problems at this point, jump to Troubleshooting console port problems to isolate and fix the problem.
Saving HyperTerminal Settings for Future Use
Step 7 From the HyperTerminal menu, select Step 3. (In the future, simply double-click this icon in the HyperTerminal folder to open the saved connection.). This saves the Session for future use. The new named session appears in the HyperTerminal folder represented with an icon like the one you clicked in
Step 8 Assuming you have already connected the router and laptop using a roll-over cable, you can verify that the session is active by pressing the Enter key on your laptop a couple of times. You should see the router prompt in the HyperTerminal window.
SYMPTOM: No connection.
SYMPTOM: No response from router once connected to router via console.
SYMPTOM: Only getting garbage from the router.
