Connecting a Network Cable

Before connecting or replacing a network cable, use a network cable tester to check whether the new network cable is functional.

The new and old cables must be of the same model or be compatible.

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.

1. Wear an ESD wrist strap. For details, see ESD Protection.
2. Check the model of the new network cable.

   A network cable with the shielding function is recommended. The network cable without the shielding function has poor anti-static capability. If the static electricity is too large, the system may not respond or restart. As a result, the system is suspended and restarts.

3. Number the new network cable.
   • The number of the new network cable must be the same as that of the old one.
   • Use the same type of labels for network cables. Record the name and number of the local device on one side of a label and those of the peer device on the other side. Attach a label 2 cm (0.79 in.) away from the end of a network cable.

4. Route the new network cable in the same way (underfloor or overhead) as the network cable to be replaced.

   Route the new cable in the same way as the old one. 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 when routing.
   • The minimum bend radius of a network cable is 4 cm (1.57 in.). Check that the cable insulation layer is intact. Ensure that cables are routed for easy maintenance and capacity expansion.
   • Bind cables with ties when routing. Ensure that network cables are bound closely, neatly, and straight. and cable ties are in even distance and fastened properly.

5. Remove the network cable to be replaced.

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

6. Install 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.

7. Connect the other end of the network cable to the peer network port according to the network plan.

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

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

8. 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 securely connected.

9. 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.
