Software and hardware feature.


Before plug-out LPUF sub-board, use command "downlpu". After plug-out LPUF, use command "undo downlpu".The information about NE40 router's LPU boards operation (plug-out and plug-in operations) is absent in NE40's technical manual. The information about types of hot-swap and hot-plug LPU boards is absent in technical manual also. The description about modules present only. So, you should discuss with other engineers and try to get maximum help which you can reach.
