Here are few steps that i have aleady done to solve this:

1) use different CF with the same result

2) use few IOS c3845-ipbase-mz.124-18.bin, c3845-ipvoicek9-mz.124-17.bin,

c3845-ipvoicek9-mz.124-22.T.bin, c3845-spservicesk9-mz.124-13c.bin with the same result

3) tried to boot IOS from rommon mode with exactly the same after-effect

4) checked if cookie is okay. Unfortunately i cannot say that the whole cookie is okay, but beginning octets are not FF's.

cookie:

04 ff c1 8b 46 4f 43 31 33 32 38 36 32 4d 52 40

33 33 31 41 4a 42 42 ff ff ff ff ff ff ff ff ff

Could you please tell me where to look for "Chassis MAC Address" so i can compare? - first octets?

5) tried to upload ios from rommon mode without success. See logs below:

6) Removing PVDMs did not change anything

I have no idea how to solve this.

Could anyone give me advice.

Broken faulty router, that Cisco will replace if under support contract.

if you are complaining about your 3845 rebooting all the time, why are you trying to load a 3825 ios?  Get the correct ios and try again.

It's got nothing to do with the IOS. If you look at the bootup process after the router passes the bootstrap the router crashes. It's a hardware fault.

Hi,

If this is new router, most likely you have a hardware problem. Open a ticket with TAC and RMA the router

Here is more info regarding the error message:

Thanks Reza for prompt answer.

This is second hand router

Btw: your link does not work.

Reza Sharifi · ‎01-02-2012

lets try it again:

http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_tech_note09186a00800f67db.shtml

I just tried it. It should work now

HTH

Reza Sharifi · ‎01-02-2012

If it is second hand then I assume you don't have a service contract to replace it. Since the router keep rebooting, try using the following link to see if you can break in to the router and load a different IOS.

I was trying to load different IOS several times but still Cisco was rebooting itself.

As i stated previously Cisco was originaly shipped with c3845-spservicesk9-mz.124-13c.bin, but i was trying c3845-ipbase-mz.124-18.bin, c3845-ipvoicek9-mz.124-17.bin, c3845-ipvoicek9-mz.124-22.T.bin as well

Of course that was only possible from Rommon mode (from few CF's cards or tftp), because watchdog prevents from giving me prompt.

Regarding "Troubleshooting Watchdog Timeouts" page it is probably software watchdog timeout (i pasted all the output).

Reza Sharifi · ‎01-02-2012

If you could get to Rommon mode, you could also use Xmodem to try to load a new IOS.

I was trying to upload IOS to Cisco with confreg 0x3922 but at the end got error that the file cannot be opened.

Ready to receive file c3845-ipbase-mz.124-18.bin ...

I need to check another CF card tomorrow and give us an update here.

paolo bevilacqua · ‎01-03-2012

There is no need to use xmodem with modern routers.

You can do tftpdnld -r to load and boot the image without writing to flash.

However from previous posts I suspect you have faulty hardware.

Maciej Bylica · ‎01-04-2012

Is there any way to find what exactly is out of order?

Dont' you think that cookie might be corrupted?

paolo bevilacqua · ‎01-04-2012

Broken faulty router, that Cisco will replace if under support contract.

Maciej Bylica · ‎01-07-2012

Paulo, unfortunately that Cisco is not under any support contract

Don't you think that cookie might be responsible for such Cisco behaviour?

No.

You can buy a support contract at any time.
