Question about 1FE-TX module and router 2811

[rafalnow]

I have a router 2811 and 2621XM. A 1FE-TX module is installed on the 2621XM. What can happen when I install a module on router 2811. Can I damage port on router 2811. Is it worth to try to connect module to 2811?

Please help.

 Thank you

Hi 

The module is supported in 2800 routers and should work in a 2811 router. Make sure both routers are powered off when you  transfer the module.

Hello

It's me again.

I have a question.

I have two routers 2811 with the same IOS. The 1FE-TX module in one router works fine but the same module in the other router causes a PCI bus error. IOS systems on both routers are the same.

What could be wrong?
