Today I was given some networking gear from a local business that shut down. One piece being a 24port 10/100 with 2 10/100/1000 ports 3com switch and a Cisco 1841.

Looking at the back of the 1841 it has a card installed in slot 0 marked WIC 1DSU-t1 V2 and slot 1 seems to just have a cover plate on it. Oh and it has a CF card inserted below the cover plate on slot 1.

I am wondering if this 1841 could be setup to replace my current router? I have a Verizon DSL for my home connection if that matters.
 
You would need 2 ethernet ports, or a ADSL WIC and an ethernet port. Yes, it can be used as a DSL router. Fun as hell to set up and play with, too.
 
Ok other then now knowing for sure this router can be setup for my home DSL network, I think I am more confused the I was before.

I was under the impression this router was pulled and boxed with nothing removed from it. But the first reply suggests it need a WIC for the WAN and another for the LAN?

I had assumed as the second reply says that the WIC in slot 0 was connected to the T1 they used for WAN and that the switch was connected to one of the 4 other ports on the back?

Damn I knew I had a lot to learn before I could even think about configuring the software on this thing but I had no idea the hardware it self was going to be this confusing...
 
You do not need a WIC to use the router. You can simply use FastEthernet0 to connect to your dsl modem, and FastEthernet1 to connect to your pc or switch. Of course it will NOT be plug and play and you will have to learn how to configure it or have someone who knows what they are doing configure it for you.
 
Ok that makes a bit more sense to me, thanks.

I do know a guy who use to work for a company who did Cisco networks but since I am in no rush to install this router I would like to learn how it works my self. If I can just figure out where to start.

I assume the thing has to be passworded and I haven't a clue what the password would be or how to reset it back to default.

Anyone care to tell me how to go about accessing it or at least point to me to a site where I can learn the Cisco basics?
 
Mmmm 1841.

I've been trying to pick one up off of ebay but I keep getting sniped by people in the last 20 seconds.

I'll buy that 1841 from ya :D Quick easy money for you

Just look for password recovery cisco on google and it will point you to where you need to go.

Scince that router is a 1841 it is not a fixed configuration router so you can add or replace any WIC cards in there. WIC cards are used to supply diferent WAN interfaces for the router and for DSL you have a WIC card that works as a DSL modem but you can set it up as mentiond above using an external modem in bridged mode.

If you want to set it up in your home and you dont know a thing about Cisco then you will have a really hard time doing it, because you will have to configure it and the configuration isnt as simple as your regular DSL router (SDM hepls but not much)

I was going to say the same thing, lol.

If you don't know IOS, it's going to be tricky to set up, also, you'll want to know how to make changes to it if you need to. An 1841 is probably a waste for you.

Me three. I have a 1841 for my home router, running DSL and I love it. I have been looking on getting another one to put at a family members house so I can setup some tunneling and voice. pm if you are willing to sell. Actually I may be about to buy a cable modem WIC, so I may have an extra DSL WIC to get rid of soon.

Why an 1841 for the family? An 1811 seems like it would be a better option cause of the built in switch.
 
Well as much as I could use the money and believe me the first thing I did when I got home with it was do an eBay price check, the geek in me just wont part with it.

I didn't get a console cable or anything with it and looking at the 1841 info in the Cisco site I will need one. So I called up my friend who use to work with Cisco gear and he is going to bring one by for me. I asked is he had any DSL WIC cards but he doesn't. He only has ISDN, T1, and 56k cards. He did however inform me of a place right up the road from me that sells used Cisco gear on eBay so I am going to give them a call.

He also has a Cisco switch and his books from when he took his CCNA that he is going to drop off. Something tells me I am about to learn a whole lot more about networking then I even thought there was to it.

I am sure the DSL WIC will actually complicate the setup process but my modem is almost 10 years old and I have been concerned it is going to release it's magic smoke some day soon. Also eliminating another piece of hardware will be great.

Anyway yes the 1841 is way overkill for my needs but it finally gives me a reason and a way to learn more about Cisco Systems.
 
Exciting fun :D

I need to pick up some serial cards to plop in our 2611's here at work for some fun times in our labs.

How about a trade for an 871 + cash? That would suit your needs well, and give me an 1841, which would suit my needs nicely too.
 
I say keep the 1841 and have some fun :D

Thats what I would do.

Cisco console cables are a dime a dozen. We have a whole drawer full of them and then some. I have like 4 of them floating around the lab too

I'll see your 1811 and raise 2620 with dual wic-t1 and as a backup 3620 with 2w1e.. and if someone wants to buy the 3620 great...

1811 > 2620

I've got a lot of equipment I'm not using, not sure if you want to play this game.:D
 
I just picked one up off ebay for cheap finally...

TGA we should have a configuration party! :D

Cept mines going to be for a work test lab =(
 
The 1841 is one of my favorite routers. It's the only one I have ever set up that just plain worked. My previous employer ran it for years without rebooting it.

Nice, I ended up having some things come up yesterday so I didn't manage to get the console cable or books yet.

I have to admit I am a bit intimidated by this thing.

It wasn't too long ago that I built my first pfsence box and picked up a HP managed switch for Vlans. And even that was a bit of a learning experience for me.

Now my friend is all about coming over and setting this thing up for me but I am not sure how I feel about that. I have never let anyone touch my network before. However I suspect it may be easier for me to let him set up the network since I will the have a working configuration file that I can use with the books to help me grasp what is going on.

But on the other hand I will undoubtedly get much more satisfaction out of configuring it on my own not to mention much more confidence in making changes to it in the future.

I guess I could give it a go on my own with the books for a bit and then look to here and my friend to find out where I am going wrong if I can't get things working. Does that sound reasonable to those of your with Cisco experience or am I just setting my self up for much frustration and confusion?

You are going to have a blast setting it up. There's enough documentation via google that you can get through it too. And with the books you will get, you will be set.
 
Shhhhhhhhh :D

I'm technically a Cisco noob but I still get by... I did make the nub mistake of forgetting to no shut my ports... that was a fun bang my head against a wall for an hour.
 
You guys are vultures! :D Anyway if you were smart you'd let him tear his hair out and then want rid of it. Oops the cat's out of the bag! :D

TGA, if you're serious about setting it up then go for it. Otherwise I'd part ways with it and find something else to start out with. But that's just me. Oh and whoever posted about 1841's costing $1000 with no WICs has not been looking hard enough. I just priced stuff with Candela Networks and I can get an 1841 386D/128Flash for $590 and a 1 year warranty. That's about as good as I've found them.

As much as I should use Dynamips to save money, I keep wanting to buy real hardware. And now that I have the 'approval' from the boss (read: wife) I will be buying some new toys for studying with. ;)

You can find them cheaper than that, IIRC. For that money I'd get a 2811.
 
I'm already planning on getting 2811's anyway. If you know of another vendor that has 2811's for that price, please PM me and let me know. I'm looking for the best pricing available. Candela will do 2811s with 768D/256Flash for $725. I just bought my 2511 with octals from Candela and the device looks brand new. I've been very impressed with them thus far. A bit slow to ship, but its free shipping so you can't really complain about that. I also found out that Dantrak is actually just north of me here in Chicago so I know have a local place to pick up my Skeletek rack as well.
 
Enterprise SW too?

OMG I would LOVE to get an 1841 for free....... Have so much fun working with the 1811 at work. Gotta learn IOS now.
