Figure 4-24 Example of the labels on the DC power cable
On the loaded cabinet side, the label marked with "A01/B08- -2" on the cable
indicates that the cable is -2 DC supply, which is from the eighth connector on the
second row of -48V bus bar in the cabinet on Row A, and Column 1 in the
equipment room.
On the distribution unit side, the label marked with "B03- -2" indicates that the
cable is -2 DC supply, which is from the loaded cabinet on Row B, Column 03 in
the equipment room.
?.2. Engineering Labels for External Cables of Alarm Box
The external cables of alarm box are connected to the first subscriber cabinet of
each row (used for power distribution). Labels posted on the first cabinet of each
row should indicate which equipment is using the access terminal.
Labels are not needed on the equipment side unless there is special requirement.
In this case, only Area 2 of the label should be filled in.

● In the power distribution unit (or the first power cabinet of a row in the transmission
equipment room), every terminal block on the - 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 which the terminal blocks are connected,
therefore which terminal is connected makes no difference. It is only necessary to give
the row and column of the power distribution unit, instead of giving the specific serial
number of the terminal block on the copper bar. For example, if the label on the loaded
cabinet side is "A01-BGND", it means that the power cable is a BGND that connects
BGND copper bar in the power distribution unit on Row A, Column 01 in the equipment
room. Information on the labels for PGND cables should be given in the similar way.
