Engineering Labels for Power Cables

This section describes the meaning of engineering labels attached to power cables.

Engineering labels for AC power cables
  • This type of labels are attached to AC power cables, including POWER, BGND, and PGND.
  • They are attached to both ends of AC power cables and only to one side of the sign plate of the cable tie.
  • The three core wires (220 V, working ground, and PGND) of a 220 V AC power cable are all covered with insulation sheaths. Therefore, each power cable requires a label only marked with AC and cabinet ID (the same for the 110 V cable and other cables).

Table 15-80 describes the label that is attached to an AC power cable.

Table 15-80  Content of the engineering label for an AC power cable

Label Content

Meaning

MN-AC

MN: cabinet ID or position number of power input (socket)

  • At the power socket side: indicates the cabinet ID.
  • At the loaded cabinet side: indicates the position number of power input (socket). A label must clearly identify the device position. If capable of being classified into rows and columns, positions of sockets can be marked by the same method as that marking labels at the loaded cabinet side. If incapable of being classified into rows and columns, positions of sockets must be specified to avoid confusion.

A label contains information about the position of the peer end of a cable (what TO: means). The label for the local end can be omitted, because the local end position has been known. Only information about peer end devices, such as a control cabinet or a cable distribution box, needs to be filled on the label.

Notice directions when attaching a label: The side of the cable tie, attached with a label, faces outside; characters on labels attached to cables in the same cabinet face the same direction, as shown in Figure 15-177.

Figure 15-177  Engineering labels for AC power cables

1. The label attached on a cable at the loaded cabinet side

Indicates the position of the PDC to which the cable is connected.

2. The label attached on a cable at the PDC side

Indicates the position of the loaded cabinet to which the cable is connected.

  • The label on the cable at the loaded cabinet side is marked A01-AC. It indicates that the power cable is connected to the power socket at row A and column 01 in the equipment room.
  • The label on the cable at the PDC side is marked B01-AC. It indicates that the power cable is connected to the loaded cabinet at row B and column 01 in the equipment room.

Engineering Labels for Network Cables

This section describes the meaning of engineering labels attached to network cables.

  • Applicable scope

    Shielded or unshielded network cables connected to network ports on the subrack board of a cabinet

  • Meaning of label content

    Table 15-81 describes two sides of a label attached to a network cable.

    Table 15-81  Content of a network cable label

    Label Content

    Meaning

    Example

    MN-B-C-D

    MN: cabinet ID

    A01: indicates the first cabinet in row A.

    B: subrack ID, numbered from bottom to top by two digits

    01

    C: physical board ID, numbered from top to bottom and from left to right by two digits

    01

    D: network port ID, numbered from top to bottom and from left to right

    01

    MN-Z

    MN: cabinet ID

    B02: indicates the second cabinet in row B.

    Z: position number. Fill in the position number for an identifiable terminal device based on site requirements.

    • If a network cable is connected to a router in a cabinet, mark the router position by cabinet ID, subrack ID, and network port ID.
    • If a network cable is connected to a network management system (NMS), mark the details where the NMS is located.

    B02-03

  • Example

    Figure 15-178 shows an example.

    Figure 15-178  Network cable label

    • A01-03- -05 indicates that the local end of the network cable is connected to network port 05 on subrack 03 in the cabinet in row A, column 01 in the equipment room. No slot number is specified.
    • B02-03- -12 indicates that the other end of the network cable is connected to network port 12 on subrack 03 in the cabinet in row B, column 02 in the equipment room. No slot number is specified.

Engineering Labels for Optical Fibers

This section describes the meaning of engineering labels attached to optical fibers.

  • Applicable scope

    Optical fibers connected to optical connectors on boards of cabinet subracks or case devices

    Optical fiber labels are classified into two types based on connection modes:

    • Labels attached to optical fibers that connect two devices.
    • Labels attached to optical fibers that connect devices to optical distribution frames (ODFs).
  • Label for an optical fiber between devices

    Table 15-82 describes the label for an optical fiber connected between two devices.

    Table 15-82  Label for the optical fiber between devices

    Label Content

    Meaning

    Example

    MN-B-C-D-R/T

    MN: cabinet ID

    If a local device and its peer device are located in different equipment rooms, device names can be used to specify their positions.

    A01: indicates the first cabinet in row A.

    B: subrack ID, numbered from bottom to top by two digits

    01

    C: physical board ID, numbered from top to bottom and from left to right by two digits

    05

    D: optical port ID, numbered from top to bottom and from left to right by two digits

    05

    R: optical receiving port

    T: optical transmitting port
