B03 -48V2
l On the loaded cabinet side, the label marked as "A01/B08- -48 V2" indicates that the cable
is used for the -48 V2 DC supply. The cable is routed from the 8th connector in row B of
the -48 V busbar in the power distribution cabinet in row A, column 01.
l On the power distribution cabinet side, the label marked as "B03- -48 V2" indicates that
the cable is used for the -48 V2 DC supply. The cable is routed from the loaded cabinet in
row B, column 03.
The label context is listed:
l In the power distribution cabinet (or the first power cabinet of a row in the transmission
telecommunications room), each terminal on the -48 V connector bar has a numeric
identification. For example, such as "08" (also mentioned as "8") in the label "A01/B08-
-48 V2."
l The PGND and the BGND are two copper bars. The terminals are directly connected to
these copper bars. Therefore, the connection of any of the terminal does not affect the
distribution of the power supply. Only the row and column numbers of the power
distribution cabinet are required. For example, if the label on the loaded cabinet side is
"A01-BGND", the power cable is a BGND cable that is connected to the BGND copper
bar in the power distribution cabinet in row A, column 01. The information on the labels
for the PGND cables must be provided in the similar way.
A.3.10 Labels for AC Power Cables
This topic provides information on labels and example of labels for AC power cables.
The labels are attached to the AC cables, including the 110/220 V, BGND and PGND cables
that supply power to the cabinets. Labels are attached to both ends of the cable. The 110/220 V,
