Even though we sell a large amount of Cisco equipment, I have had little hands-on time with the Cisco security features that can be added to a 1900, 2900 or 3900 ISR. Being a newbie to the security features I decided it would be nice to guide other newbies. Hopefully this will remove some of the fears that go along with deploying Cisco products. This series will discuss the deployment of a 1900 series router with a security license. This is an “open the box” to “in production” article. By no means is this an in depth deployment guide to all of the Cisco security features. I will try and steer clear of all of the CLI (Command Line Interface) commands but they will be necessary. I highly recommend learning the CLI to make your skillset even better.
To Reduce Intimidation (Hopefully Forever):
- ISR (Integrated Services Router): All routers can route but a Cisco ISR is not limited to what the name implies. An ISR can have added functionality like switching, voice, or security.
- WIC (Wan Interface Card): This is just a module that adds new features or expands the features of a router.
- Rollover Cable: This is a serial to RJ-45 connection. The connection is over a telnet client. For these examples we will be using Putty which is a freeware terminal client.

Opening the Box
My Cisco router came in very typical Cisco Packaging. There was a box that held another Cisco box. This has to do with the different sizes of products. We take some blame because we sometimes box, boxes in more standard sizes. I will admit one time the boxes were identical size and it was nearly impossible to get the product out.
Included:
- Box
- Router
- Compliance Document (In Plastic)
- End User License Agreement
- Power
- Foam x2
- Fedex Envelope
- License Claim Certificate
- CD
Where is the Rollover Cable? I will pause here to look for other ways to make the initial connection. If there is no other way I will make sure we send a rollover cable even if it is not included with the product.
Missing Rollover Cable Solution! The times they are a changing and I do not have to buy everyone a rollover cable. The rollover cable is no longer a requirement. This does not make this a snap but now a USB connection can be used to open a console session with the 1921.
If you can’t tell, I do work from home sometimes!
You will need one of these cables. I am sure you have one. Check your digital camera. Once you have the cable, the small side plugs into the router. Install this software.

This will require a reboot. After the reboot and after the cables are plugged-in there is now a new COM port on the computer.
Install Putty
It is hard to believe that in this day and age things still need to be done through a terminal session. Microsoft had hyper-terminal for many years, but I do not believe it is still installed with the OS. I think everyone in the know, knows PuTTY. It is a free Telnet/SSH/Terminal client software. If you did not know of PuTTY you are welcome! It can be downloaded from:
http://www.chiark.greenend.org.uk/~sgtatham/putty/
Once it is downloaded just click on the executable (PuTTY.EXE file). There are a few settings that are required to work with a Cisco device over a terminal session. Make sure COM1 is changed to COM3. That is at least the COM number I was given when I plugged in the USB cable. Make sure that Baud is 9600, data bits are 8, stop bits is 1, no parity, and no flowcontrol.
