Figure 86 Example of a label on an optical fiber between the device and the ODF
• ODF-G01-01-01-R —The local end of the optical fiber is connected to the optical receiving terminal
on Row 01, Column 01 of the ODF in Row G Column 01 in the equipment room.
•
A01-01-05-05-R —The peer end of the optical fiber is connected to Optical Receiving Interface 5 on
Slot 05, Chassis 01 in the cabinet on Row A, Column 01 in the equipment room.
Engineering labels for DC power cords
These labels are affixed to DC cords that provide power for racks, and the protection grounding cables
including the –48V, PGND, and BGND cables. The labels for DC power cords are affixed to one side of
the identification plates on cable ties.
Table 76 Information on labels affixed to DC power cords
Content Meaning
MN(BC)-–48Vn
•
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.
MN(BC)-RTN
MN(BC)-PGND
The label only carries location information about the peer equipment, control cabinet, or distribution box,
while information about the local end is not necessary.
Table 76 lists information about two –48V power
supplies on the label. Give information for other DC voltages (such as 24V, 60V) in similar methods.
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
Table 76Figure 87 .
