MN-AC
The label only carries location information about the peer equipment and the power socket, while
information about the local end is not necessary. Make sure labels are affixed in the correct direction.
After the cable ties are bundled onto the cable, the identification plates with the labels must face up,
and the text on the labels in the same cabinet must be in the same direction, as shown in
Figure 82 Example of labels on an AC power cord
•
A01-AC (loaded cabinet side)—The power cord is connected to the socket of Row A and
Column 01 in the equipment room.
•
B01-AC (power socket side)—The power cord is connected to the loaded cabinet of Row B,
Column 01 in the equipment room.

Engineering labels for DC power cords

These labels are affixed to DC power cords that provide power for racks, and the protection
grounding cables including the –48V, PGND, and RTN cables. The labels for DC power cords are
affixed to one side of the identification plates on cable ties.

The label only carries location information about the peer equipment, control cabinet, or distribution
box, while information about the local end is not necessary.
power supplies on the label. Give information for other DC voltages (such as 24V, 60V) in similar
methods.
Meaning
MN: Rack number (row number and column number in the equipment room) or the location of
the socket where the power is led in.
The location of the socket is marked according to onsite situation. If the sockets can be
identified by row number and column number, they can be numbered following the same rule
for the rack number. Otherwise, specify the detailed locations to avoid confusing with other
sockets.
Meaning
•
Loaded cabinet side—Only MN is used to identify the cabinet number
(row number and column number in the equipment room).
•
Power cabinet side—MN identifies the row and column number of the
power distribution equipment like the control cabinet and distribution box.
BC identifies the row and column number of the –48V connector (if there is
no row number or column number, or the connector can be identified
without them, BC can be omitted). RTN and PGND have no row and
column number for identification.
•
n—Power port number in down-top and left-right order, in the range of 1 to
3.
