Issue Description
Connecting a Network Cable.
Solution
Scenario:
  • The network is to be set up over a gigabit Ethernet (GE).
  • You want to log in to the intelligent management (iMana) of the server over the management network port for device management.
  • One or more network cables do not work.
  • A network cable is to be replaced when the existing network cable does not meet length requirements after a device is replaced or moved.
Prerequisites:

1.  Precautions
  • 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. Make clear whether they are straight-through cables or crossover cables.
2.  Preparation
  • The network plan is complete.
  • Spare network cables are ready and placed near the device.
3.  Tools
  • Phillips screwdriver: used to tighten screws.
  • Electrostatic discharge (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.
Procedure:

1.  Check the new network cable model.

2.  Number the new network cable.
  • The number of the new network cable must be the same as that of 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 one end of a network cable.
3.  Route the new network cable.

Route the new network cable in the same mode 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 rack based on the installation requirements. You are advised to arrange cables in the existing mode. Ensure that cables are routed neatly and undamaged.
  • Separate network cables from power cables and signal cables for routing.
  • Bend a network cable with the bending radius no less than 4 cm (1.57 in.) to prevent damage to core wires. Check that the cable insulation layer is not damaged. Ensure that cables are routed for easy maintenance and capacity expansion.
  • Network cables must be bound to ensure proper routing. Check that network cables are bound neatly and appropriately, and that they are straightly stretched and close to each other. Cable ties are in even distance and fastened properly.
4.  Remove the network cable to be replaced.

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

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.

Connect the RJ45 connector on the network cable to the network port on the server, as shown in Figure 1.

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 operating 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 connectors are secured.

8.  Bind the new network cable with other cables.

Bind the new network cable by using the same method as the existing one. You can also remove all cable ties and bind all network cables again.
