Fast ethernet module for cisco-1720

[ekomursito]

Dear all.

My office have 3 cisco-1720 routers,

connected to the WAN backbone by using WIC-1ADSL One ADSL port module.

Recently, the WAN backbone has been upgraded to Gigabyte/Fast Ethernet system.

So I'm looking for the fast ethernet module for 1720 routers.

Unfortunatelly, the catalog said only WIC-1ENET One 10 Base-T Ethernet module is available.

Please suggest the solution so we can still use these small and reliable routers.

TIA.

Hi amit & suresh.

I had read the refered manual too, but

I did not explain may question quite well.

Allow me to describe it again.

The 1720 router has:

- One built-in 10/100MBps Fast Ethernet port

- Two modular racks

The built-in fast ethernet has been connected to our LAN. On the other side,

one of the modular rack contains the ADSL module, which is connected to our WAN.

{ADSL WAN}-----------[(ADSL module)- 1720 - (10/100BASE-T)]----{LAN}

Now we want to connect to a fast ethernet WAN like this

{Fast Ethernet WAN}-----[(FastEthernet)- 1720 - (10/100BASE-T)]----{LAN}

Thus I need a "module", that should be inserted into the modular rack to replace the ADSL module.

Hope my problem is clearer now.

TIA

Hi,

There is a WIC-4ESW a 4 port 10/100 module avalable but is is only supported in 1721 routers and above. It is not supported on 1720.

The only solution you are left with is to use WIC-1ENET card or just go ahead and replace the router with a new 1800 series router.

All right, I knew it :(

Thanks for the answer.

I got the bullet to ask the purchasing manager ;-)

Yes you can have Fast Ethernet ports, but not GB ports. Below link may clear your doubts.

Hope that helps.

Amit I posted my comments when I saw the orginal post b thinking that we wanted GB ports for ethernet connectivity.

I did not see his Second post which has posted after seeing your comments.

After seeing his second post I came to know that I misunderstood his problem.
