Cisco 827 Jumpers

[feanacar]

Can anyone tell me what the jumpers, J7, J8, and J14

do on a Cisco 827?

I'm looking for a Hardware Reset to Factory Defaults

solution.

Any help here would be appreciated. Thanks!

[feanacar]

Aw, c'mon. Does not one of the Experts here know?

Oh well, maybe I should just "experiment" a bit...

The most effective way to get back to the default settings is write erase, then power-cycle the router.

If you need to break into the router first because you have forgotten the password, here is the password recovery procedure:

I am not aware of any public document that tells you about the jumpers. In fact, the only document I could find that tells you to open the box is the one about upgrading the memory. But this does not mention the jumpers.

I would be careful about experimenting the jumpers. You could, for example, end up deleting the bootstrap from flash - in which case I guess it really would be an "initial configuration".

Sorry I could not find any detail.

I am stuck on the same question.

(after a ROMMON config-register operation, the output of my router is unreadable. So any comand are unusabe). What was the result of your experimentation?

Or does anymone have information about this?

:?

You got the serial setting screwed up. Do try speeds from 300 to 9600 in your terminal program one by one. When you see a fair amount of output coming out and you kind of type something, you got the right speed, start changing parity in term settings.

[laurentElens]

Thanks a lot!

My terminal speed was indeed set to 35400.

when I did try the righ number, I got everything in clear text :)

Hi to all,

I have received from a friend a router marked CISCO 827 because appear to be broken.

From my analisys seem that the PLD Altera EPM7128AETC100-7 could be corrupted inside because any communication ports (ethernet or serial console) talk with external peripherals. So I can't communicate by ethernet or serial console, and any reset procedure at startup have given any result.

All voltages and leds seem to be working fine, but before to trash it, I would like to try to re-program by Altera Jtag connector (J14) the PLD chip.

Another question is about the two jumper 3 ways in the electronic board as reference J7 and J8, could you explain me what about them ? I've looking all related documents available on your site but I've find nothing about them.

From my attachment are they in the regular position in standard working ?

The only big problem for me is that I am be able to register on CISCO site but when I want download the software I can't if I a reseller or others options. So

I ask something to send me these files if possible and all latest IOS or a link where is possible for me download they, as latest final test before to trash all.

Can you help me ?

In attachment some reference of the router above.

If you have something to send me please contact me to enricocoraatgmail.com before to send.

Fair value of a working 827 = $20. Is it worth to loose time with a broken one? I don't think so.

[enricocora72]

It's true that for the value you shoud be in reason suggesting to do not loose other time, but for something people enjoy also with little when can solve a

problem that appear unsolvable only programming the boards. I have all to do this but without firmware and software it's hard. So if you can help me it would be appreciated. At the end of games I don't know why Cisco cannot give me a software as final user...It's a very strange policy for me ! Expecially considering the actual value of the board.

For me it is now only a challenge to be able to win against the board. It's the last beach.

Cisco will not give the info and you need to get the software eligaly , I got 40Gb software not by cisco after they refused to help just search and you find . Jumper settings will never be given. If its  just 20usd to loose then just try. If you succeed just share the info :)
