Input pin protection about DP83867

Hello,

About DP83867,
When a signal is put to the RJ45 side when Power does not do ON, will the TD_P/N_x pin exceed absolute maximum ratings through a transformer?
About pins such as (TD_P_x, TD_M_x)
Or do have any protection circuit inside?
Is not it necessary to think about protection circuit?

Because absolute maximum ratings of the input pin does not write it to DP83867 data sheet, please tell how I should use it.

Regards.

K Hashi.
