II. For Signal Cables
The two sides of the label affixed on the signal cable carry information about the
location of the ports connected to both ends of the cable, as shown in Figure C-7.
The information is given like this:
Area 1 contains the location information of this end of the cable.
Area 2 (with the mark "TO:") contains the location information of the other end of
the cable.
Area 3 has been folded up inside the label.
Figure C-7 Printed parts on the label for signal cables
Seen from the cabling end of the equipment, the text part of the label is on the right side
of the cable. The side with "TO:" that is facing outside carries the location information of
the opposite end. The other side carries the location information of the local end.
Therefore, the information in Area 1 at one end is the same as the information in Area 2
at the other end of the cable. In other words, the local information at one end is the
opposite information at the other end.
C.2.8 Points for Attention
When printing/writing and affixing labels, keep the labels clean.
Because the label paper is made of moisture-proof and waterproof material, do not
use ink-jet printers or ink pens to print or write labels.
Affix labels neatly.
Cable ties bundle power cables in the same position, with ID plates on the same
side.
The positions of "up", "down", "right" or "left" are all based on the viewpoint of the
one working on the label.
C.3 Engineering Labels for Optical Fibers
These labels apply to the optical fibers that connect the optical interfaces on the boards
in a subrack or a box.
