Installing E1 controller cards

[bradlesliect]

I need to install 2xE1 controller cards on to a 7200 router.Does this router have to be power off first or can the cards be inserted while the router is still live?

Brad,

You need not bring down the router for installing these cards on a 7200 router

Have a look at this link
