I recently acquired a Cisco 2611XM that looks like this:

Now the one I have has only 1 FastEthernet port (Was expecting 2) but I was wondering I purchase a WIC1T - CSU/DSU module for it could I use that to accept the Internet IP address from my ISP? (if i configure it for DHCP etc)?

IF not, please advise on how I can allow something like that to occur with my 2611XM router. Thank you for your time.

I do have a CCNA with Cisco, but this seems to be a bit out of my knowledge base of what I've done so far.

Do you have a T1 to connect to the WIC1T? It not, what purpose would it serve? What form does your connection to your ISP take? –  David Schwartz Feb 16 '13 at 2:24
    
I have ethernet cable that comes in from the Outside FiOS installation. So a current Netgear N750 home router is capable of accepting that connection (via ethernet). I want to replace the N750 with my router so I can configure a VPN and other things as a lab with another partner. –  Bain Feb 16 '13 at 2:42

There are two fast Ethernet ports on a Cisco 2611XM and two are shown in your picture. The two ports with the yellow labels under them are both FE ports. A T1 WIC won't do you any good unless you have a T1 to connect to it.

So the 2611XM is 100% usually with a 2 ports? If it is not two ports that means its probably a 2600 series not XM ... Is that correct? --- I received one without two fast Ethernet ports. –  Bain Feb 16 '13 at 2:39
    
@Bain: That is my understanding. A 2610XM has 1 FE port. A 2610 has 1 10MBps Ethernet port. See table 1-1 of this Cisco guide. –  David Schwartz Feb 16 '13 at 2:47
    
So the router I purchased says its 2611 XM but there is a sticker running through the whole where a 2611XM router would have that 2nd ethernet port. I believe my router is a fraudulent 2611XM :( –  Bain Feb 16 '13 at 2:51

@Bain: Wow, can you put up a picture? What does the sticker say or look like? (There's a guide to spotting counterfeit routers from US-CERT. Usually the differences are subtle though.) –  David Schwartz Feb 16 '13 at 2:58
    
So did a bit more research, thank you David S. For all your information and knowledge. I looked at the model being sold and it was being sold as a 2611XM but I was sent a 2610XM ... Big difference as there is only 1 FA port on the xx10XM version. Will be talking with seller for sure. Thank you so much. I don't think its fraudulent though, I cannot turn it on and check the hardware as I need to get a console cable adapter. –  Bain Feb 16 '13 at 3:52
