Note:
In the power distribution box (or the first power cabinet of a row in the transmission
equipment room), every terminal block on the -48V connector bar has a numeric
identification. For example, in the above label of "A01/B08--48V2", "08" (or
sometimes "8") is the numeric identification of the terminal block.
PGND and BGND are two copper bars. On each bar, the terminal blocks are
short-circuited. Therefore, which terminal is connected makes no difference. You
only need give the row number and column number of the power distribution box,
instead of giving the specific serial number of the terminal block on the copper bar.
For example, if the label on the load cabinet side is "A01-BGND", it means that the
power cable is a BGND that connects BGND copper bar in the power distribution
box on Row A, Column 01 in the equipment room. The information on the labels for
PGND cables is similar.
