The second (unused) pair voltage (AC and DC) should be dead zero. Don't worry about the voltage on the live pair.

The thinking is that there's a possibility of the second pair inducing noise into the first. I saw a condition once in a similar situation whereby the connector block was bleeding voltage from one pair to the other, thus creating crosstalk between the two even though the 2nd pair was "unused".
