fxp0 up down

** I have cleared the alarm by using:-
# set chassis alarm management-ethernet link-down ignore

Can someone tell me what could be the reason for fxp0's link Proto "down" ?
What steps could i take to troubleshoot the issue.

Some Details:-
Router:- M120
Junos:- 10.4R9.2

How it went down :-
I configured fxp0 unit 0 and assigned it's IP 192.168.1.5/24. Uploaded a file then i deleted fxp0 unit 0

Command used:-
# delete interface fxp0 unit 0

after that link proto for fxp0 went down.

First off is anything connected?

Nope nothing is connected with fxp0.

If nothing is connected that is why it is down. You can disable the interface if you aren't using it.

Yes ok i know that layer 2 proto is down because nothing is connected to it , but i m confused that why was it up before i made unit 0 ? i mean no cables were connected before.
Is there any reason that fxp0 was UP/UP(without cable) before i made fxp0 unit 0.
