Connecting a Network Cable

Connecting a Network Cable

Connect a network cable in the following scenarios:

  • The network needs to be set up over a gigabit Ethernet (GE).
  • You want to log in to the iMana/iBMC of the server using the management network port for device management.
  • One or more network cables do not work.
  • A network cable needs to be replaced if the existing network cable does not meet length requirements after a device is replaced or moved.


  • Use a network cable tester to check that the new network cable works properly.
  • Check that the new network cable is of the same model as or compatible with the network cable to be replaced. Determine whether they are straight-through or crossover cables.
  • Before installing a network cable to a network port, check that the network cable connector is intact and the pins have no sundries or deformation.

The following tools are available:

  • Phillips screwdriver: used to tighten screws
  • ESD wrist strap or ESD gloves: used to prevent ESD damage
  • Diagonal pliers: used to trim the cable ties after binding cables
  • RJ45 crimping tool: used to make network cable connectors
  • Network cable tester: used to test the cable connectivity
  • Multimeter: used to test the resistance


  1. Check the new network cable model.
  2. Number the new network cable.

    • The new network cable must have the same number as the one to be replaced.
    • Use the same type of label for network cables. Record the name and number of the local device to be connected on one side of the network cable, and those of the peer device on the other side. Attach a label to the position 2 cm (0.79 in.) away from the end of a network cable.

  3. Route the new network cable.

    Route the new network cable in the same way (underfloor or overhead) as the network cable to be replaced. Note the following points:

    • Underfloor cabling is recommended because it is tidy and easy to route. Route cables in the cabinet based on the installation requirements. You are advised to arrange new cables in the same way as existing cables. Ensure that cables are routed neatly and undamaged.
    • Separate network cables from power cables for routing.
    • Bend a network cable with the bending radius of no less than 4 cm (1.57 in.) to prevent damage to core wires. Check that the cable insulation layer is intact. Ensure that cables are routed for easy maintenance and capacity expansion.
    • Network cables must be bound using cable ties to ensure proper routing. Check that network cables are bound together neatly and properly, are routed straightly and close to each other. Cable ties must be installed at an even spacing and fastened properly.

  4. Remove the network cable to be replaced.

    Remove the network cable from the network interface card (flexible NIC) or board in a cabinet.

  5. Connect the new network cable.

    Note the following:

    • Connect the new network cable to the same port as the removed one.
    • Install the network cable in the network port securely.
    Figure 3-22 Connecting a network cable to management and service network ports

  6. Connect the other end of the network cable to the peer network port.

    Connect the other cable connector to the peer device based on the network plan. Note the following:

    • Connect the new network cable to the same port as the removed one.
    • Install the network cable in the network port securely.

  7. Check that the new network cable is functioning properly.

    Power on the device, and ping the peer device connected by the new network cable. If the peer device cannot be pinged, check whether the network cable is damaged or the connectors are not secured.

  8. Bind the new network cable with other cables.

    Bind the new network cable in the same way as the existing network cables. You can also remove all cable ties and bind all of the network cables again if necessary.
