Help setting up Cisco Router

Experts,

I have this Cisco 1800 Series router that I am supposed to configure for my company.  I'm pretty much a noob when it comes to this stuff, but the job was given to me when I opened my mouth and said I had taken some router classes back in college.

Anyway, I've pulled out the flash card and it is completely blank, however I do have a bunch of back up files that were given me on a usb thumb drive.  On the thumb drive I see files such as:

home.tar
common.tar
wlanui.tar
c181x-adventerprisek9-mz.124-15.XY1.bin
sdmconfig-1811-1812.cfg
securedesktop-ios-3.1.1.45-k9.pkg
sslclient-win-1.1.4.176.pkg

What exactly should I copy over to the flash card.  What are the basic files the router needs to run?
Also, I am running windows 7.  What happened to hyperterminal? How are people setting up a console connection to cisco routers from windows 7?

c181x-adventerprisek9-mz.124-15.XY1.bin is the operating system, or IOS.  That should be all it needs to boot up.  You can try copying that over to the flash drive.  If that doesn't work, you would have to restore the IOS through ROMMON, you can read about how to di that at the following link:

Hperterminal no longer exists in Windows7.  You can see alternatives here:  http://helpdeskgeek.com/windows-7/windows-7-hyperterminal/

I recommend PuTTY:  http://www.chiark.greenend.org.uk/~sgtatham/putty/

Use putty. It is better then hyperterminal. Do a search for it online and you will find it. Once you have logged in w/ privileged mode you should be able to run "write erase" and then issue the "reload" command. When it reboots you will be prompted if you want to go through "setup mode" to configure your router. Enter yes and then type in the config you want after each question to setup your router.

Thanks uescomp, I'll give it a go.  I justed downloaded a program called PuTTY and am able to setup a console session that way.  Watching the router go through a boot up process now on the command line since I added that ISO file to the flash card.

Going through setup mode as itnetworkn stated will get you going and probably be about all you need.  Fortunately routers are pretty simple to setup (unlike firewalls) unless you are trying to do a lot of complex routing.  If you have additional questions please ask.

I concure,

Install Putty as it's freeware. Copy all the files listed to the flash drive and reinsert the card and reboot.

The SDM "sdmconfig-1811-1812.cfg"program is to run the Cisco GUI. A little easier to use the the CLI. (Command line interface.)

Once booted up you can use the automatic setup "CLI" to step through initial configuration as long as you have the LAN and WAN IP/subnet masks and gateway addresses. passwords, etc
Then you can fire up a web browser and log into the router with the LAN IP you assign.
Write down your IP addresses and username/passwords as you go so you can gain access to the device via WWW or CLI.

Let us know if you need some basic routing lessons.

Hi,
Cisco router uses Internetwork Operating System (IOS) for functioning.Each router comes with its default IOS.They are usually stored in flash memory and have *.bin extension.

Cisco Router also needs startup configuration which is stored in NVRAM.If one is present in the NVRAM it automatically loads it else you have to configure it manually when the router boots.Its not that difficult to configure.

Windows 7 doesn't come with Hyperterminal.You can use the Windows XP hyperterminal in win7,  
From Windows XP copy:
      * hypertrm.exe from C:\Program Files\Windows NT\
      * hypertrm.dll from C:\Windows\System32\
to a same folder.

else you can try teraterm pro or putty.

While you can use the SDM GUI I highly recommend learning the CLI.  Cisco is not well known for their user-friendly GUI design.  They have gotten better over the years but CLI is better.  Plus we can tell you verbatim statements to enter in the CLI.  If you are willing to give us actual internal IPs we can even write statements and you can just copy/paste them in PuTTY (although you wouldn't learn much that way).

Ok, think I have it running.  Was able to login and type "show run" to see the running config.  Not sure what most of it means, but I remember the "show run" command from class :-)

Ok, so here's my situation.  The place I work at is basically 2 sister companies (Company A and Company B) owned by the same owner.  Both companies are in the same building.  Anyway what they are asking me to do is setup the router to have 2 networks, 1 for each company.  Then I need to allow 2 IP addresses on Company A's network to talk with Company B's network, and visa versa.

Company A's desired Network IP 10.10.10.0
Company B's desired Network IP 10.10.20.0

Then allow 10.10.10.10 - 10.10.10.11 to have access to 10.10.20.0
and allow 10.10.20.10 - 10.10.20.11 to have access to 10.10.10.0

Back panel of the router looks like the image shown here on Cisco's site:

http://www.cisco.com/en/US/docs/routers/access/1800/1801/hardware/installation/guide/01_hw.html

Any idea how I can configure the router to do this?

Thanks for all the reply's guys.  Had google searched and downloaded PuTTY while you guys were typing the suggestion to get it :-) - so guess i'm on the right path.

Anyway, going through the router config right now after typing in "write erase" per itnetworkn's advice.
Also, definitely willing to learn some CLI as I'm probably going to be the one managing this thing from here on out.

Going through the config setup now.  It's asking questions that I'm not sure what do so, such as:

Would you like to enter basic management setup? [yes/no]
I said yes, then it asks:
Enter community string [public]:
I have no idea what this is, so I rebooted router and said "no" to management setup.

Then after is lists all the ports on the back of the router, it asks:
Enter interface name used to connect to the management network from the above interface summary:

I have no idea what this management network is or which interface i should choose.

Anyway, they are shutting the lights down on me here in the office.  I'll be back on monday to continue this.

community string is just referring to SNMP setup. You do not need to have it to get your router to work, so you can skip it for now and add it later.

Your interface questions are just going to ask you which port needs what IP addresses. For example, if Internet is plugged into Serial 1 then that is where you put the config at.

After going through the System Configuration Dialog, once the router has booted up, as I sit and watch the console connection via PuTTY, I see the following lines:

IP CEF must be enabled first !
%Error opening tftp://255.255.255.255/network-confg (Timed out)
%Error opening tftp://255.255.255.255/cisconet.cfg (Timed out)

%Error opening tftp://255.255.255.255/network-confg (Timed out)
%Error opening tftp://255.255.255.255/companyname.cfg (Timed out)

Then it continually pops up lines like these every 30 seconds or so:

%Error opening tftp://255.255.255.255/cisconet.cfg (Timed out)

Not sure what these errors are about.  Anyway, here is my current config after going through the System Configuration Dialog:

After further thought, I probably should NOT have assigned the 10.10.10.1 address to the Fe0 port right?

I guess what I want to do is have the outside internet come in on either Fe0 or Fe1
Then on Fe2 - Fe8 I want to have setup to operate on the 10.10.10.0 network
And on Fe9 I want to have setup to operate on the 10.10.20.0 network
With both 10.10.10.0 and 10.10.20.0 being able to connect to the internet through Fe0 or Fe1

I assume you do not need a WIC card for a T1 connection, and that you can plug your Internet connection into one of your FastEthernet ports. If this is correct, then yes your logic is correct you can configure it in the way you specified.

Ok, you guys got me to a good working point with setting up the router.  I'll award points and open up new specific questions for the actual configuration of stuff.
