Table 4-44 Contents of the label
Content Meaning
MN(BC)-
B--48Vn
MN(BC): BC is written right under MN.
B: chassis number, numbered in bottom-up order with two
digits, for example, 01.
n: power socket number, numbered as 1 to 3 in the bottom-
up and left-to-right orders.
On the loaded cabinet side, only MN is used to identify the
cabinet.
On the power cabinet side, MN
identies the row and column
number of the power distribution equipment like a control
cabinet and distribution box, and BC
identies the row and
column number of the -48 V connector. If there is no row
number or column number, or the connector can be
identied
without them, BC can be omitted. It is unnecessary to identify
the row and column number for BGND and PGND.

The label only carries location information about the destination direction of the
power cable whereas information about the local end is unnecessary. That is, the
label only carries location information about the opposite equipment, the control
cabinet, or the distribution box. Table 1-30 lists the information on two -48 V
power supplies on the label. The information on other DC voltages, such as 24 V
and 60 V should be given in similar methods.
Make sure that labels are
axed in the correct direction. That is, after the cable
ties are bundled onto the cable, the
identication plates with the labels should
face up, and the text on the labels in the same cabinet should be in the same
direction. For details, see Figure 4-183.
Figure 4-183 Example of the labels for DC power cables
The meaning of the label in Figure 4-183 is as follows:
● On the loaded cabinet side, the label "A01/B08--48V2" on the cable indicates
that the cable is -48 V DC supply, which is from the eighth connector in row B
of -48 V bus bar in the cabinet in row A, and column 1 in the equipment
room.
