The labels in
l
"A01-03-01-01" indicates that the local end of the user cable is connected to port 1 on
slot 1, chassis 03 of the cabinet in row A, column 01 in the equipment room.
l
"MDF-G01-01-01-AR" indicates that the opposite end of the user cable is connected to
the terminal in row 01, column 01 of the MDF in row G, column 01 in the equipment
room.
A.5.6 Engineering Labels for Power Cables
This section describes the engineering labels for power cables, including DC and AC power
cables.
A.5.6.1 Engineering Labels for DC Power Cables
DC power cable labels are affixed to the DC power cables that provide power supply for
cabinets, including the -48 V, PGND, and BGND cables. Here, the DC power cables also
include power cables and protection ground cables.
The labels for DC power cables are affixed to one side of the identification plates on cable
ties.
describes the meaning of contents on the DC power cable labels.
Table A-51
DC power cable label content
Content
Meaning
MN(BC)-
B--48Vn
MN(BC): BC is written under MN.
B: chassis number, numbered bottom to top with two digits, such as
01.
N: power socket number, numbered 1 to 3 bottom to top and left to
right.
On the loaded cabinet side, only MN is used to identify the cabinet.
On the power cabinet side, MN identifies the row and column number
of the power distribution equipment like a control cabinet and
distribution box, and BC identifies the row and column number of the
-48 V connector. If there is no row or column number, or the connector
can be identified without them, you can omit BC. It is unnecessary for
BGND and PGND to identify the row and column number.

PGND
The label only contains information about the destination direction of the power cable.
Information about the local end is unnecessary. That is, the label only contains information
about the location of the equipment on the other end of the cable, the control cabinet, or the
distribution box. Table D-8 lists the information that appears on the label about the two -48 V
power supplies. Provide the information about other DC voltages, such as 24 V and 60 V in
similar way.
Make sure that labels are affixed in the correct direction. That is, after the cable ties are used
to bundle up the cable, the identification plates with labels should face up and the text on the
labels in the same cabinet should be in the same direction. For details, see
