Cisco 1721 + WIC 4ESW


I have a brand new Cisco 1721 router (IOS 12.3).

I have a brand new WIC4ESW (four port ethernet switch) plugged into the back.

The WIC light is on, saying 'WIC 1 OK', but I cant see any interfaces to configure through the telnet/hyperterminal config.

When I plug in a network cable to any of the slots on the WIC nothing happens - not even a status light on the port.

Have I got a faulty WIC or am I doing something wrong?

The documentation says that you need IOS 12.3 (2)XC - what is the (2)XC and how can I tell if my router has this?

Does anyone know how to configure this thing? It's driving me mad hence the points.

A 'show ver' will tell you what IOS you have.
The problem you describe is down to an incorrect version of IOS - the interfaces don't show up, status lights stay off... been there plenty of times before !!  ;)
Issue a show version.  The first line will show you your IOS version.  It should be greater or equal to 12.3.2XC.  

The IOS version with the XC is basically a hardware update.  The switch module should be supported in anything higher.  For instance, 12.3.10.

When you do a show version, look at the bottom of the output.  It should mention what interfaces you have installed.  It should list that you have greater than four fast ethernet interfaces.

Lastly, cisco's default on routers are to have all interfaces shutdown.  You'll need to console or log into the router and no shut the interfaces.  They should be int  FastEthernet1 - 4.

What tim means by no shut is to issue the no shutdown command on all the interfaces .

will do a 'sh ver' on monday when i'm back at work.

will post the results.

thanks for your help so far.
FYI, "show diag" will show diagnostic information for any port adapters, network modules, and/or WICs in a router (including integrated devices). My guess is that you're not running a version of IOS that supports the WIC (which the "show version" or "sh ver" command will confirm), so the "show diag" will list the WIC-4ESW as an "Unknown Port Adapter."

Here's what happens when I rip a 'sh ver'

This IOS version is 12.3.6? so it should be work right?

The bootstrap is 12.2.7 is this causing an issue?

Your version - 12.3(6b)
Required version - 12.3 (2)XC

They're not the same !

IOS releases are NOT cumulative.  What you get in 12.3(6b) is not what you get in 12.3(2), although the core 12.3 stuff is the same.

There's simply not enough space on the flash card to store everything, so Cisco break these out into hardware specific versions.

With respect to the bootstrap file, these are pretty simple images that are common across most releases.  These just get the box up and running - think BIOS.

The software you need is this:


This requires 64Mb system RAM, 16Mb flash, which you have  + the image is 8.23Mb.  I've downloaded it to check it's the right one, and yes... this WILL work.

If you need it, drop me a line, plus your SmartNET entitlement number or details of Cisco support agreement, and I'll send it to you -

how can I get the IOS update myself? I'd like to know for future reference.

Thanks Tim!
You need to have an active SMARTNet service contract in order to be entitled to download IOS updates (except critical security updates). If you have a SMARTNet contract, you can use your contract number to create a Cisco Connection Online (CCO) account here:

Once you have a valid CCO login, you can download IOS images at the software center:

(You have to be logged in to see the hyperlinks to download the software).
yvsupportAuthor Commented:

I have a CCO login, but it only grants me guest access.

I guess this is why I can't get the IOS update.


How do you get a SMARTNet contract and how much do they cost?

I feel a little hard done-by as I bought a router and wic4esw to perform a specifc job, but cannot use them together unless I buy a support contract.

I do not want support - just the IOS update. C'mon Cisco - this sucks!

I only bought this router/wic interface last week - no support contract was offered.

Tim_Holman - I do not have these details - so cannot mail to you.

can anyone help?

thanks in advance.
Call Cisco TAC at (800) 553-2447 and explain what you need, and they should allow you to download the IOS you need free of charge. Make sure you have the router serial number handy.

I have the right IOS bn file.

How do I load it into the router?

Do I need to use TFTP or can I just issue a reload/reboot command or something similar?

I've never done this before (you can probably guess!)

thanks in advance.

Tim HolmanCommented:
Use TFTP.  A TFTP server download plus instructions are in this link...  ;)
yvsupportAuthor Commented:

I cant see a link for TFTP. Do you have a preferred one to use?
Tim HolmanCommented:
Good point !
Looks like Cisco have discontinued it due to a security flaw.

'The Microsoft (r) Windows (r) based TFTP server previously provided by Cisco Systems has been discontinued and is no longer supported by Cisco Systems. This software suffers from a security bug described in ( Persons still using the server should consider replacing it with any of the high quality freeware and shareware TFTP servers. As a historical note, the Cisco TFTP server was released to customers in 1995 and at a time when no other freely available TFTP servers existed.

Today, there are many TFTP servers available, can be easily found by searching for "tftp server" on your favorite internet search engine. Cisco does not specifically recommend any particular TFTP implementation.

It is also useful to note that modern versions of IOS also support the use of FTP instead of TFTP for loading of images or configuration files. Use of FTP overcomes a number of inherent limitations of TFTP including a lack of security and a 16 megabyte file size limitation. '

So - take your pick !  ;)
