HWIC-1ADSL and 1841

Question:

As with this post,

https://supportforums.WS-C3560X-48T-L  cisco.com/message/789836#789836 I have an 1841 and want to install an HWIC-1ADSL.

 I have tried the Software Tool mentioned but get awfully confused by the end result.

My 1841 show version is:

Cisco IOS Software, 1841 Software (C1841-SPSERVICESK9-M), Version 12.4(22)YB3, RELEASE SOFTWARE (fc1

System image file is "flash:c1841-spservicesk9-mz.124-22.YB3.bin"

Cisco 1841 (revision 7.0) with 118784K/12288K bytes of memory.

Just wanting to know if the HWIC-1ADSL will work with this IOS?

Answer:

No it won't.  You need to use, a minimum of, 12.4(4)T.  Pay attention to the "T" train.

Go here.  Look at the left-hand column.

Click the 12.4 > 12.4T and choose for the IOS of your choice.

I suppose the latest and greatest firmware would be the most appropriate, in the 12.4 range, eg 12.4.24T8(ED), would you agree?

I can't make that decision for you.  For me, I would.  Read the Release Notes so you'll know what open cavaets are still available.

When I speak to my supplier, they tell me that support for this device is discontinued and that it is no longer available for a new contract.

1841 is already End-of-Sale since 01 November 2010, however, you can try to get your vendor WS-C3560X-48T-S  to download the IOS for you.
