Engineering labels are affixed to both ends
of the various cables to identify the physical positions of cables on different
devices. Labels on the cables facilitate correct and orderly connection of
cables, and easy maintenance after the installation.
There are two types of engineering labels,
specialized for the power cables and signal cables respectively. The power
cables include the AC power cables and DC power cables (excluding the power
cable that connects the distribution box and the cabinet). The signal cables
include external cables of alarm box, Ethernet cables, optical fibers, trunk
cables and subscriber cables (excluding the antenna feeders).
In case there is
special requirement from the user of the equipment on the description method of
the labels, the labels should be printed accordingly. However, this must be
stated in the self-check report.

There are two types of engineering labels
for power cables and signal cables respectively.
I. Label for signal cables
The label for signal cables is L-shaped
with fixed dimensions, as shown in Figure A-1 (expressed in mm).
|
(1) Dividing line
|
(2) Cut dotted line
|
Figure A-1 Label
for signal cables
The dividing lines on the label help to
specify more clearly the position of a cable. For example, there is one between
the cabinet number and the frame number and another one between the frame number
and the slot number. The dividing line is 1.5mm 0.6mm in size with the color
of PONTONE 656c (light blue).
The cut dotted line helps to fold the label
when affixing it to the cable, and its size is 1.0mm 2.0mm.
There is a mark “TO:” (upside
down in the figure) at the lower right corner of the label. The mark is used to
identify the opposite end of the cable on which the label is affixed.
II. Label for power cables
The label for power cables should be
attached to the identification plate on the cable ties that are bundled to the
cable. The identification plate has an embossment of 0.2mm 0.6mm around
(symmetric on both sides), and the area in the middle is for affixing the
label, as shown in Figure A-2 (expressed in mm):

Figure A-2 Label
for power cables
The contents can be printed or written on
the labels. Printing is recommended for the sake of high efficiency and
eye-pleasant layout.
I. Template for the printing
The Word-form template is available for
label printout. You can get the template from H3C local office.
When using the template, you can directly
modify the contents on the template, and the following should be observed:
l
The settings of centered characters, direction,
and fonts should not be changed.
l
When there are too many characters to be filled
in, zoom out the characters, but make sure the printouts are clear and legible.
II. Cells merging on the template
To merge the cells, you should first
recover the table structure (if gridlines are displayed, you can start from Step
3 directly).
1)
Select the menu item [Edit/Select All].
2)
Select the menu item [Format/Borders and
Shading/Borders]. Select Box and click <OK>.
3)
Drag the mouse to select the cells to be merged
and select the menu item [Table/Merge Cells].
If two merged cells are still not enough to
accommodate the characters, use multiple lines.
III. Requirements on the printer
To print the labels, laser jet printer must
be used, although there is no restriction on the model of the printer. Before
printing the label, set up the page and try the printing on ordinary blank
paper (both sides are blank):
1)
Cover the blank paper onto the whole page of
label paper, and check whether the page setup conforms to the requirement.
2)
Make sure the printer properties, such as
"paper size" and “direction”, have been set correctly.
3)
If the warning prompt as shown in Figure A-3 appears before printing, click <Ignore> to continue the printing.
Figure A-3 Warning
prompt before printing
If the printout confoms to the requiremnt,
print it to label paper. If the printout does not conform, adjust the page
setup and try the printing again, until the correct printout is produced. The
method of adjusting the page setup is as follows:
4)
Select the menu item [File/Page Setup].
5)
Select the Margins tab page.
6)
Select Left for Gutter Position.
7)
Set Header and Footer as 0, and adjust
the values of Top, Bottom, Left, and Right.
After the page setup has been made correct,
save it for future use. This page setup is only necessary in the first time you
use the template to print the labels.
IV. Requirements on feeding the
printer
Different from the ordinary paper, the
label paper is composed of two pages. No matter what model of printer you are
using, feed in the labels one after another by hand. Never use the auto-feed
mode in order to avoid jamming the labels. Different models of printers may have
different feeding modes, make sure to feed in the labels correctly.
V. Requirements on the printed
label
Make sure the printed label satisfy the
following requirements:
l
All the printouts must be on the label, and
nothing should be printed on the bottom page of the label.
l
Contents in the cells should be aligned in the
center. In a single-line printout, the dividing lines and the mark
“TO” should not be covered by the printed characters.
l
When the cells are merged and the printouts are
made in multiple lines, avoid covering the mark “TO” when printing
the texts by using the space bar to move the printing contents to the next
line.
Use the black oiliness markers to write the
labels.
In special cases, black ball-pens are
allowed, although not recommended. When writing with the ball-pen, take care
not to leave the oil on the label, which may contaminate the label and blur the
words..
The delivered
marker has two nibs. Make sure to use the smaller nib to write the labels.
For the sake of easy recognition and good
looking, the font in handwriting should be close to the standard typeface as
much as possible. Table A-1 shows the standard typeface.

Figure A-4 Writing
direction of the label
After printing or writing the label, remove
the label from the bottom page and affix it to the signal cable, or the
identification plate of the power cable.
I. Signal cable label
1)
Affixing the label to the signal cable
The label is affixed 2cm from the connector
on the signal cable. In special cases, for example, to avoid cable bent or
affecting other cables, other positions are allowed to affix the labels.
The steps to affix the label to the cable
are shown in Figure A-5, Figure A-6 and Figure A-7. The finished labels should be on the right or top of the cables, according to different cabling methods. The left part of the figures shows the method to affix the label when the cable is laid vertically, while
the right part of the figures shows the method to affix the label when the
cable is laid horizontally.
2)
Stick the label to the proper position on the
cable, fold the narrow part of the label according to the directions shown in Figure A-5.
Figure A-5 Stick
the label onto proper position of the signal cable
The lengh of the narrow part is based on an
external cable diameter of 2.6mm, after this part has been stuck to the back of
the label, it may not overlap the entire printed part.
3)
Fold the printed part along the dotted line
according to the directions shown in Figure A-6.
Figure A-6 Fold
up the label
4)
After the printed part of the label has been
folded up, the narrow part of the label should be covered completely, as shown
in Figure A-7.
Figure A-7 Appearance
of affixed labels on signal cables
II. Affixing the label to the
power cable
Remove the label from the bottom page, then
affix it to the identification plate on the cable tie. The label should be
stuck to the rectangular flute, and should be stuck to only one side of the
identification plate. Make sure to affix the labels on the same side of the
identification plates. The cable ties are bundled at 2cm from the connectors, and
other positions are allowed in special circumstances.
Cable ties should be bundled on both ends
of a cable. After the bundling, the finished identification plate should be on
top of the cable in horizontal cabling, or on the right side of the cable in vertical
cabling. Make sure the label is facing out, as shown in Figure
A-8.
Figure A-8 Appearance
of affixed labels on power cables
I. For power cables
Labels for power cables are only affixed on
one side of the identification plates. On the labels, there is information (the
part after the mark “TO:”) about the location of the device on the
other end of the cable, like the location of control cabinet, distribution box
or power socket.
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 A-9.
The information is given like this:
l
Area 1 contains the location information of
local end of the cable.
l
Area 2 (with the mark "TO:") contains
the location information of the opposite end of the cable.
l
Area 3 has been folded up inside the label.
Figure A-9 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; and 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, and vice versa. In other
words, the local information at one end is called the opposite information at
the other end.
l
When printing/writing and affixing labels, pay
attention to keep the labels clean.
l
Since the label paper is made of moistureproof
and waterproof material, ink-jet printers and ink pens are forbidden for
printing and writing labels.
l
Labels should be affixed with good order in
alignment.
l
Cable ties should be bundled in the same
position of power cables, with identification plates on the same side.
l
The positions of “up”,
“down”, “right” or “left” are all based on
the viewpoint of the engineering person who is working on the label.
These labels are affixed to the Ethernet
cables that connect the boards in the frames, or on the cables that connect
HUBs and servers or agents of the Value Added Service (VAS) products.

serial number of the Ethernet port. The definitions of the cabinet number and
frame number are the same as those described in Table A-2 above.
4)
If it is a stand-alone HUB without any cabinet
or frame, the label should contain specific location information that
identifies the HUB.
5)
The serial number on the HUB, the network port
number of the agent and the location of stand-alone server should be specified
according to actual connection.
II. Example of the Label
Figure A-10 shows the label on the Etherent cable:

“B02-03-12” indicates that the opposite
end of the Ethernet cable is connected with Ethernet Port 12, Frame 03 of the cabinet on Row B, Column 02 in the machine room.
These labels are affixed to the optical
fibers that connect the optical interfaces on the boards in a frame, or on the
device boxes. There are two types of labels for optical fibers: one is for the
fiber that connects the optical interfaces on two devices, the other is for the
fiber that connects the device and the Optical Distribution Frame (ODF).

The labels are affixed to the DC cables that
provide power for the cabinets, and the protection grounding cables, including
the -48V, PGND, and BGND cables. The labels for DC power cables are affixed to
one side of the identification plates on cable ties.

|
MN(BC)--48V1
|
MN(BC): BC is written right under MN.
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 the
control cabinet and distribution box, BC identifies the row and column number
of the -48V connecter (if there is no row number or column number, or the
connecter can be identified without them, BC can be omitted). BGND and PGND
have no row and column number for identification.
|
|
MN(BC)--48V2
|
|
MN(BC)-BGND
|
|
MN(BC)-PGND
|
The label only carries location information
about the opposite equipment, the control cabinet or the distribution box,
while information of the local end is not necessary. Table A-5ists the information of two -48V power supplies on the label. The information for other DC voltages (such as 24V, 60V) should be given in similar methods.
II. Example of the label
Make sure that labels are affixed in
correction direction. That is, after the cable ties are bundled onto the cable,
the identification plates with the labels should face up, and the text on the
labels in the same cabinet should be in the same direction, as shown in Figure A-13
Figure A-13 Example of the labels on the
DC power cable
In Figure A-13, (1) indicates the label on the loaded cabinet side, which carries the information about the position of the cable on the power distribution box. (2) indicates the label on the distribution box side, which carries
the information about the position of the cable on the loaded cabinet side.
On the loaded cabinet side, the label
marked with “A01/B08--48V2” on the cable indicates that the cable
is -48V2 DC supply, which is from the 8th connecter on the second
row of -48V bus bar in the cabinet on Row A, and Column 1 in the machine room.
On the distribution box side, the label
marked with “B03--48V2” indicates that the cable is -48V2 DC
supply, which is from the loaded cabinet on Row B, Column 03 in the machine
room.
l
In the power distribution box (or the first
power cabinet of a row in the transmission machine room), every terminal block on
the -48V connector bar has a numeric identification. For example, in the above
label of “A01/B08--48V2”, “08” (or sometimes
“8”) is the numeric identification of the terminal block.
l
PGND and BGND are two copper bars, on which the
terminal blocks are short-circuited, therefore which terminal is connected
makes no difference. It is only necessary to give the row and column of the
power distribution box, instead of giving the specific serial number of the terminal
block on the copper bar. For example, if the label on the loaded cabinet side
is “A01-BGND”, it means that the power cable is a BGND that
connects BGND copper bar in the power distribution box on Row A, Column 01 in
the machine room. Information on the labels for PGND cables should be given in the
similar way.
The labels are affixed to the AC cables
that provide power for the cabinets, and the protection grounding cables,
including the POWER, PGND, and BGND cables. The 220V AC cables and related PGND
and BGND cables are covered with insulating sheath, so the labels only need to
contain the words of “AC" and the cabinet number. The labels for AC
power cables are affixed to one side of the identification plates on cable
ties.
I. Meaning of the label
Table A-6shows the information carried on the labels for the AC power cables.

MN-AC
|
MN: serial number of the cabinet or the
socket where the power is led in
The location of the socket is marked out
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
cabinets. If the sockets cannot be identified by rows and columns, specify
the detailed locations to avoid confusing with other sockets.
|
The label only carries location information
about the opposite equipment and the power socket, while information of the
local end is not necessary.
II. Example of the label
Make sure that labels are affixed in
correction direction. That is, after the cable ties are bundled onto the cable,
the identification plates with the labels should face up, and the text on the
labels in the same cabinet should be in the same direction, as shown in Figure A-14:
Figure A-14 Example of the labels on the
AC power cable
In Figure A-14, (1) indicates the label on the loaded cabinet side, which carries the information about the position of the cable on the power socket. (2) indicates the label on the power socket side, which carries the information
about the position of the cable on the loaded cabinet side.
On the loaded cabinet side, the label
marked with “A01-AC” indicates that the power cable is connected to
the socket of Row A and Column 01 in the machine room.
On the power socket side, the label marked
with “B01-AC” indicates that the power cable is connected to the
loaded cabinet of Row B, Column 01 in the machine room.
