Installing Hardware and Connecting Cluster Cables

Installing Hardware and Connecting Cluster Cables

Hardware Installation

Install CSS cards and MPUs according to card installation instructions.

To install or remove CSS cards that are not hot swappable on running MPUs, power off the MPUs first.

Connecting Cluster Cables

Preparations

  • 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)

Precautions

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 an 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.

Procedure

  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 3-27 and number these labels starting from 1.
    Figure 3-27  Attaching labels
  3. Connect cluster cables according to connection rules, which are selected based on the switch model and CSS card model.
    • When you hear a click, the electrical cable, optical module, or optical fiber has been 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 3-28  VSTSA CSS card connections (S7706&S7706 PoE&S7712)
    NOTE:

    Follow these rules when connecting VSTSA CSS cards: Each VSTSA CSS card has four ports. All ports with the same port number and color must be connected, as shown in the preceding figure. For example, port 1 in blue on the left chassis must be connected to port 1 in blue on the right chassis.

    The CSS set up using VSTSA CSS cards allows at most one faulty cluster cable.

    Figure 3-29  VS04 CSS card connections (S7706&S7706 PoE&S7712)
    NOTE:
    Follow these rules when connecting VS04 CSS cards:
    • Each VS04 CSS card has four ports. All ports with the same port number must be connected, as shown in the preceding figure. For example, port 1 in blue on the left chassis must be connected to port 1 in blue on the right chassis. The two chassis can be connected through one cable. However, it is recommended that the two chassis be connected through multiple cables.

    • Each CSS card on the local chassis can be connected to only one CSS card on the peer chassis.

    Figure 3-30  VS08 CSS card connections (S9706&S9712)
    NOTE:

    Follow these rules when connecting VS08 CSS cards: Each VS08 CSS card provides eight ports, which are divided into two groups. Ports in the groups with the same ID and color must be connected. For example, ports in group 1 in blue on the left and right chassis must be connected, and ports in group 2 in blue on the left and right chassis must be connected. See the preceding figure to connect cables between groups. Ports in a group can be connected in any sequence, but each group must have at least one cable connected. Full-mesh connections are recommended.

  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.
