hi pradeepa,
were you using a external pwer brick or inline power? the power outage might have something to do with it. hope the phone is not damaged!
in any case you can try the following-
1. power down the phone
2. plug the cable back in
3. hold down the # key
4. when the lights blink green red and green, leave that key and hit 123456789*0#
5. it will ask u to hit 1 to keep the network config opr 2 to delete it
6. hit 2 and the phone will reset
let me know if this works. im assuming that another ip phone is working on the same ethernet cable with or without inline power.
