Installing Hardware and Connecting Cluster Cables

Installing Hardware and Connecting Cluster Cables

Installing Service Cards

Install service cards according to card installation instructions.

Connecting Cluster Cables


  • Required components: electrical cables or optical modules with matching optical fibers or AOC cables
  • Required tools: cable ties, fiber binding tapes, labels, and an ESD wrist strap (or ESD gloves)


When removing or connecting an optical fiber, do not look into the optical port without eye protection. The laser emitted from the optical port can injure your eyes.

  • Take ESD protection measures before the installation.
  • Prevent the cables from being twisted.
  • Insert or remove optical fibers carefully to prevent damages to optical fiber connectors.
  • Ensure that the bend radius of an optical fiber or electrical cable is larger than its minimum bend radius. The minimum bend radiuses of QSFP+ cables, SFP+ to SFP+ cables, and AOC cables are 50.8 mm, 25 mm, and 30 mm respectively. The bend radius of optical fibers is generally larger than or equal to 40 mm.
  • Clean the optical fiber connector with alcohol swab or air-laid paper along one direction, if the connector is dirty.
  • Push the connector inward gently first, and then pull the handle on the electrical cable to remove it.


  1. Wear an ESD wrist strap and connect the ground terminal to the ESD jack on the chassis.
  2. Attach labels to both ends of a cluster cable according to Figure 3-32 and number these labels starting from 1.
    Figure 3-32  Attaching labels
  3. Connect cluster cables according to the connection rule shown in Figure 3-33.
    • When you hear a click, the electrical cable, optical module, or optical fiber is installed properly.
    • When removing the electrical cable, optical module, or optical fiber, push the connector or handle inward first, and then pull it out.
    Figure 3-33  Service port connection rule
    Service ports are connected in two ways according to link distribution:
    • 1+0 networking

      Each member switch has one logical CSS port and connects to the other member switch through physical member ports on one service card.

    • 1+1 networking

      Each member switch has two logical CSS ports, and physical member ports of the logical CSS ports are located on two service cards. CSS links on the two service cards implement link redundancy. The preceding figure shows the cable connections in this networking.

    When connecting cluster cables, pay attention to the following points:
    • Physical member ports of a logical CSS port on one switch must connect to physical member ports of a logical CSS port on the other switch.
    • In 1+1 networking, it is recommended that two service cards have the same number of CSS links.
    To ensure reliability, pay attention to the following points when using the preceding two service port clustering networkings:
    • To ensure high reliability, you are advised to use 1+1 networking and configure multi-active detection (MAD).
    • At least two physical member ports on an LPU must be added to one logical CSS port.
    • It is recommended that the cards where uplink ports and MAD-enabled port are located be the LPUs that are not used for CSS connections.
  4. Arrange the cables in order and bundle the cables with a cable divider.
  5. To power on the switches, ensure that power cables and ground cables are correctly connected and then switch on the external power modules and built-in power modules in turn.
