•
Affix labels with good order in alignment.
•
Avoid cable bents or other positions that might affect cable installation when you stick a label or
bundle a cable tie with a power cord identification plate.
•
Bundle cable ties at the same positions of power cords, with identification plates on the same
side.
•
The positions of "up," "down," "right" or "left" are all based on the viewpoint of the engineering
person who is working on the label.
Examples
The label examples in this document are for reference only.
Engineering labels for twisted-pair cables
These labels are affixed to twisted-pair cables that connect cards in a chassis.

MN-B-C-D
MN
—Rack number
•
M
—Row number of the rack in the equipment room, in the
range of A to Z.
•
N
—Column number of the rack in the equipment room, in
the range of 01 to 99.
For example, A01.
B
—Chassis number
Numbered in top-down order with two digits, for example, 01.
C
—Slot number
Numbered in top-down and left-right order with two digits, for
example, 01.
D
—Ethernet port number
Numbered in top-down and left-right order with two digits, for
example, 01.
MN-Z
MN
—Rack number
•
M
—Row number of the rack in the equipment room, in the
range of A to Z.
•
N
—Column number of the rack in the equipment room, in
the range of 01 to 99.
For example, B02.
Z
—Location number
Location number of the terminal or device onsite.
If you connect the cable to a router in a rack, specify the rack
number, chassis number, and Ethernet port number, for
example, B02-03-12. If you connect the cable to a terminal or an
NMS, specify the location number of the terminal or the NMS.
The information provided on the following labels is different, subject to different devices that the
twisted-pair cables are connecting. For example:
•
On a label for the twisted-pair cable that connects a device and a server:
For the device end
—Rack number, chassis number, and Ethernet port number on the
device.
For the server end
—Rack number and chassis number, or the specific location of the
server if the server is laid separately.
•
On a label for the twisted-pair cable that connects the device and a terminal:
For the device end
—Rack number, chassis number, and Ethernet port number, or the
specific location of the device if the device is laid separately. The definitions of the rack
number and chassis number are the same as those described in
