Hi All,
We have a 7206vxr router with a pos interface: its PA-POS-1OC3 card currently in up/down status:
We already repalced the card but still same (up/down) condition.

I tried putting an internal loop on the interface (new card): still it doesnt come up! as per my knowledge internal loopback means a loop within the card right? then its not coming up for internal loop also means even the new card has gone faulty or do I need replace the whole chasis?
