Connecting Ethernet Cables

Connecting Ethernet Cables


  • Do not power on the router before you finish connecting cables.
  • Notice flags on interfaces when connecting cables. Incorrect cable connection may damage interface modules or the router.

Tools and Accessories

  • Diagonal pliers
  • Cable ties
  • Marker
  • Network cables (separately purchased)
  • Network cable labels


  1. Select Ethernet cables of appropriate quantity and lengths according to the number of ports and measured cabling distances.
  2. Attach temporary labels to both ends of each Ethernet cable and write numbers on the labels to identify the Ethernet cables. For details, see Engineering Labels for Network Cables.
  3. Lead the Ethernet cables into the cabinet from the top cable inlet (for overhead cabling) or bottom cable inlet (for on-ground cabling), and route the cables from one side of the cabinet.
  4. Connect one end of an Ethernet cable to an Ethernet interface of the router and the other end to an Ethernet interface of the remote device.

  5. Arrange the Ethernet cables to make them parallel, and then bundle them with cable ties. Use diagonal pliers to cut off redundant cable ties.
  6. Remove the temporary labels from the Ethernet cables, and then attach formal labels 2 cm away from the connectors at both ends.

Follow-up Procedure

Check the following items after connecting Ethernet cables:

  • Labels are correctly filled and securely attached to cables, with texts facing the same direction.
  • Cables and connectors are complete, intact, and tightly connected.
