3.  Example

Figure D-11 shows a label on the Ethernet cable.

Figure D-11 Example of a label on the Ethernet cable

“A01-03-10-05” indicates that one end of the Ethernet cable is connected with Network Port 05, Slot 10, Subrack 03 of the cabinet at Row A, Column 01 in the equipment room.

“B02-03-12” indicates that the other end of the Ethernet cable is connected with Ethernet Port 12, Subrack 03 of the cabinet at Row B, Column 02 in the equipment room. It does not provide the slot number.

D.5.4  Labels for the Fiber That Connects Two Devices

These labels are affixed to the optical fibers that connect the optical interfaces on the boards in a subrack, or on the box-shaped devices. There are two types of labels for optical fibers: one is for the fiber that connects two devices, the other is for the fiber that connects the device and the optical distribution frame (ODF).

1.  Meaning of the Label

Table D-5 shows the information on the labels affixed to the optical fibers that connect two devices.

Meaning

Example

MN-B-C-D-R/T

MN: Cabinet number

For example, A01

B: Subrack number

Numbered from the bottom up with two digits, for example, 01

C: Physical slot number

Numbered from the top down and from the left to right with two digits, for example, 01

D: Optical interface number

Numbered from the top down and from the left to right with two digits, for example, 05

R: Optical receiving interface

T: Optical transmitting interface

MN-B-C-D-R/T

MN: Cabinet number

The meanings are the same as above. When the local device and the opposite device are not in the same equipment room, MN can be the name of the equipment room.

B: Subrack number

C: Physical slot number

D: Optical interface number

R: Optical receiving interface

T: Optical transmitting interface

2.  Example

Figure D-12 shows the label on the optical fiber between two devices. 

Figure D-12 Example of the label on the optical fiber between two devices

“A01-01-05-05-R” indicates that the local end of the optical fiber is connected with Optical Receiving Interface 05 in Slot 5, Subrack 01 in the cabinet at Row A, Column 01 in the equipment room.

“G01-01-01-01-T” indicates that the opposite end of the optical fiber is connected with Optical Transmitting Interface 01 in Slot 01, Subrack 01 in the cabinet at Row G, Column 01 in the equipment room. 

D.5.5  Labels for the Fiber That Connects the Device and the ODF

1.  Meaning of the Label

Table D-6 shows the information on the labels affixed to the optical fibers that connect the device and the ODF.

R: Optical receiving interface

T: Optical transmitting interface

ODF-MN-B-C-R/T

MN: Row number and Column number of the ODF

M: The cabinets going from front to back (in a row) in the equipment room are numbered from A to Z.

N: The cabinets going from left to right (in a column) are numbered from 01 to 99.

For example, G01 is the ODF at Row G and Column 01.

B: Row number of the terminal

Range from 01 to 99. For example, 01-01

C: Column number of the terminal

R: Optical receiving interface

T: Optical transmitting interface
