Getting Started - Reseting router to factory default settings
Hello everyone,
First piece of advice: "It doesn't matter if your hardware is either old or new, always do a reset to default factory settings."
It is amazing how often people forget about that and start setting up on top of someone's else config. Not really a big deal for routers, switches, etc; But imagine if we were talking about a pre-install computer, bought used, and that computer have a keystroke capture software??? Thats my point.
In my case, m router came with a password, that I didn't have, and I end up having to first reset the password and then resetting the router. I promise talk about resetting password next post.
This are the steps to reset a cisco router to factory default settings:
In order to perform the procedures described in this document, you must have "enable" (also known as "privileged EXEC") access on the router. At the prompt (HOSTNAME>) type: enable. This should change the prompt to (HOSTNAME#). This is the privileged EXEC mode.
This method uses the config-register 0x2102 command in global configuration mode.

This method uses the config-register 0x2102 command in global configuration mode.
- Check the configuration register on the router by issuing the show versioncommand.
The configuration register setting is displayed in the last line of the show versioncommand output and should be set to 0x2102. If this is not the case, enter theconfig-register 0x2102 command once in global configuration mode.
If the show version command is issued again, the same line in the command output will have '(will be 0x2102 at next reload)' appended to the current register setting.router#configure terminal router(config)#config-register 0x2102 router(config)#end router#
- Erase the current start-up configuration on the router with the write erasecommand.
- Reload the router with the reload command. When prompted to save the configuration, DO NOT save.
Once the router reloads, the System Configuration Dialog appears.router#reload System configuration has been modified. Save? [yes/no]: n Proceed with reload? [confirm]
The router is now reset to the original factory defaults.--- System Configuration Dialog --- Would you like to enter the initial configuration dialog? [yes/no]:
I still not sure what all this information means but this is my boot sequence post. Lets see hows that change inthe future.

Getting Started - Making the connection
Hello everybody,
As you all know already, my idea here is to document and share my experience with my cisco 2610. Eventually I might look for a CCENT / CCNA but now I just want to get familiar and be able to configure and troubleshoot my "toy".
Last time I wast telling how to build the console cable, now its time to hookup to the computer and fire up.
When you get your router, you will probably first connect to it via console serial connection. This connection is made possible by an RJ-45-to-RJ-45 rollover cable (it's a light blue CAT5-ish cable), an RJ-45 to serial connector, and a PC equipped with HyperTerminal. To connect the rollover cable to the router, follow these steps:
Once all of the cables are connected, you need to set up HyperTerminal, which can be found (in Windows 2000) by selecting Programs | Accessories | Communication. When you first start HyperTerminal, you will have to configure it in order to connect to the router. To configure HyperTerminal, select File | Properties and you will see the Properties page shown in Figure A.
In our example, we are going to configure COM1, so we'll select COM1 from the Connect Using drop-down menu and then click Configure. The COM1 Properties page is shown inFigure B.
In order to connect to your Cisco router, you will need to verify that the options are configured as they were in Figure A. Once you've verified the changes, click Connect, which is the left button shown in Figure C, and then press [Enter].
Now when I turn my router on, with HyperTerminal setup and open, this is what I got:

Before you can do anything with the router, we first need to get access to it.
Console cable is a cable which has an RJ45 connector at one end (to connect to your Cisco devices) and serial connector at the other end (to connect to your PC).). If you, like me, bought a used router you mostly probably have this cable, and even tough its easy to buy one online: i.e.ebay, they are cheap and you should have no problem with it.
Right now Im looking for "instant gratification" so because I dont have the patience to wait I decide to build my own cable. Looking around the Internet I found lots of information but most of then arent as easy to understand as I was expecting. Many sites have some complex contraptions: crossover cables, adapters, adpters for adapters, etc. I was looking for something simple: One cable, RJ45 in one end and a DB9 on the other.
So, here my set of instructions about how to build one.
First we start with the parts:
Lets start crimping the RJ45 connector. I personally use TIA/EIA 568A wiring diagram to all my cables, so I will continue doing so:
With one side of the cable done lets start the DB9 connection. The following diagram shows how each cable, by color, should be connected:
The Blue/White and Blue must both connect to pin 5 on the DB9. Pins 1 and 9 are not connected.
Once the cable its done, here's how you connect the cable:
Thats it for now.

This is my router. Right now its a stock router, that means no additional cards. The plan here will show what can we do now and expand the routers capabilities along the way. I bougtht mine from Craigslist but you can find on eBay as well. They are pretty inexpensive these days.
