Checking the Connections Between the NMS Computer and the Equipment

Checking the Connections Between the NMS Computer and the Equipment

When an NIC port on the NMS computer is connected to the NM port on the equipment over a LAN, you need to confirm that the network cable is connected correctly. You also need to ensure that the rates of NM port on the equipment and the port on the switching equipment in the LAN are set to consistent values and the working mode of Ethernet port on the equipment and the port on the switching equipment in the LAN are also set to consistent values.

Prerequisites

  • An IP address is assigned to the NE.
  • The NMS computer and the relevant equipment are connected to the LAN through network cables. The IP addresses of the NMS computer and the equipment are on the same network segment.
  • The U2000 is installed, and the computer is started.
  • The port on the switching equipment in the LAN supports the adaptive mode.
  • The rate and working mode are supported by the port on the switching equipment in the LAN.

Tools, Equipment, and Materials

U2000

Precautions

  • If a port on the switching equipment in the LAN supports the adaptive mode and can operate at the same rate and in the same working mode as the NM port on the switching equipment, both parties can communicate with each other after performing auto-negotiation.
  • If a port on the switching equipment in the LAN does not support the adaptive mode, both parties can communicate with each other only after you set the rate and working mode to the same values for the NM port on the switching equipment and the port on the switching equipment in the LAN.
NOTE:

This topic considers the Windows OS as an example of NMS server.

Procedure

  1. Checking the connections between the NMS computer and the gateway equipment.
    1. Check the network cable. The NMS computer and the gateway equipment are connected to the LAN through a straight-through cable. The NM port of the gateway equipment is on the PCX board.
    2. Remove the network cable and check the wire sequence at both ends of the network cable. The network cable needs to be a straight-through cable because the NMS computer is connected to the equipment through a LAN.
    3. Insert the network cable. Generally, the LINK indicators in green for the NIC port on the NMS computer and the NM port on the PCX board are normally on, and the ACT indicators blink.



    4. Test the connectivity between the NMS computer and the equipment.

      • On the NMS computer, choose Start > Run. In the Run dialog box, enter cmd and click OK.
      • Enter a ping command, such as ping 192.168.0.101.
        NOTE:
        192.168.0.101: indicates the IP address of the NE in the example.
      • Press Enter to run the ping command.

        If the statistical data in the DOS window contains Lost = 0 (0% loss), it indicates that no packets are lost and the Ethernet communication is normal.

        If the statistical data in the DOS window contains Request timed out, it indicates that the Ethernet communication is abnormal. Check whether the IP addresses of the NMS computer and the NE belong to the same network segment and have the same mask; check the connection of network cables. Rectify the fault, if any, before performing another test.

        NOTE:
        • To browse the receive/transmit status without affecting the test, press Ctrl+Break.
        • To stop the ping command and browse the receive/transmit status, press Ctrl+C.

  2. Checking the connections between the NEs and the gateway equipment.
    1. Using optical power meter to check optical power of the fibers between the NEs and the gateway equipment.
    2. Insert the fibers into the line board interface. Generally, the LINK indicator in green for the port is normally on, and the ACT indicators blink.
