6.4.5.1 Engineering Labels for DC Power Cables

These 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 PGND cables.
The labels for DC power cables are affixed to one side of the identification plates on cable
ties. For details of the labels, see

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.

"A01-03-01-01" indicates that the local end of the user cable is connected to port 1 in
slot 1, chassis 03 of the cabinet in row A, column 01 in the equipment room.
"MDF-G01-01-01" 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.
Meaning
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 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 number or column number, or the
connector can be identified without them, BC can be omitted. It is
unnecessary to identify the row and column number for BGND and
PGND.
