Possible hardware error 1 Year, 3 Months ago

Just received my lab and am working through Lab 3 in the workbook.
Placed the WC1T into W0 in the 2611XM. Router sees the serial card and allows me to issue configuration commands for S0/0. After configuration the interface will not come up
show ip interface brief shows Status = down, Protocol = down for S0/0.
I now power down the router, place the card into W1 and then power the router back up. Now the interface starts as expected.
show ip interface brief shows Status = up, Protocol = up for Serial 0/0.
How can this be - I would have expected the WC1T in W1 to have be S0/1?
Can anyone explain what is happening here?
Does this indicate a hardware problem with W0?
thanks,

Hi,
I have never seen a failure like that. They use two different controllers. So let's look at it a different way.
With the power cord to your right and the open slots facing you. Put the serial module in the w0 slot which is on the right and closest to the power input.
Let it boot, then post the show int for the serial interface.
Then do the same moving the serial module to the other slot.
What we expect to see is that if you only have one module installed it will always show up as s0/0. When you have two installed, it then becomes s0/0 and s0/1.
Make sure you have no configuration on either when you run the test and we can go from there.
As another side note, the port will generally come up instantly and then once it senses no cables attached(or a wrong configuration for a serial setup) it may go down. But in the exact manner it goes down depends on if you have a cable connected or such.
