Example of the label on the optical fiber between the device and the ODF
“ODF-G01-01-01-R” indicates that the local end of the optical fiber is connected with
the optical receiving terminal on Row 01, Column 01 of the ODF in Row G Column 01 in
the machine room.
“A01-01-05-05-R” indicates that the opposite end of the optical fiber is connected with
Optical Receiving Interface 5 on Slot 05, frame 01 in the cabinet on Row A, Column 01
in the machine room.
B.4 Engineering Labels for Power Cables
B.4.1 Labels for DC Power Cables
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.
I. Meaning of the label
Table B-5 shows the information carried on the labels for the DC power cables:

Information on labels affixed to the DC power cables
Content
Meaning
MN(BC)--48V1
MN(BC)--48V2
MN(BC)-BGND
MN(BC)-PGND
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.
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
B-5 lists 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.
