MN-AC
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

The label only carries location information about the peer equipment and the power socket, while
information of the local end is not necessary. Make sure labels are affixed in the correct direction.

face up, and the text on the labels in the same cabinet must be in the same direction, as shown
