Connecting High-speed Cables

Connecting High-speed Cables


  • Both ends of an idle high-speed cable must be covered by an ESD cap.
  • The bend radius of high-speed cables must be larger than the minimum bend radius. Overbending high-speed cables may damage wires in the cables.
  • When the CE8850-64CQ-EI is installed in an 800 mm deep cabinet, it is recommended that a maximum of 12 high-speed cables be configured. Otherwise, the front door of the cabinet cannot be closed because of the cables.

Tools and Accessories

  • ESD wrist strap or ESD gloves
  • Diagonal pliers
  • Cable ties
  • Marker
  • Temporary labels
  • High-speed cable labels


  1. Determine the number and type of ports to be connected and plan the cabling routes.
  2. Select high-speed cables of appropriate quantity and lengths according to the number of ports and measured cabling distances.
  3. Wear an ESD wrist strap or ESD gloves. Ensure that the ESD wrist strap is grounded and in close contact with your wrist.
  4. Attach temporary labels to both ends of each high-speed cable and write numbers on the labels to identify the high-speed cables.

    For the operation procedure, see Engineering Labels for User Cables.

  5. Connect high-speed cables to ports of the switch.

    Find the ports matching the numbers on the high-speed cables and plug cable connectors to the ports. After verifying that all high-speed cables are correctly connected, go to 6.

    Hold a high-speed cable connector in a correct direction when inserting it into a port. When you hear a click, the high-speed cable is securely connected to the port. See Figure 8-4.
    Figure 8-4 Connecting a high-speed cable
    To remove a high-speed cable, gently push the cable connector and then pull the handle of the connector. Do not directly pull the cable connector with force. See Figure 8-5.

  6. Bundle high-speed cables. Arrange the high-speed cables to make them parallel, and then bundle them with cable ties at an interval of 150 mm to 300 mm. Use diagonal pliers to cut off redundant cable ties.
  7. Replace all the temporary labels with permanent labels on the high-speed cables.
