S12704, S12708, and S12712 Clustering Using CSS Cards

S12704, S12708, and S12712 Clustering Using CSS Cards

Context

The S12704&S12708&S12712 switches support clustering using Cluster Switching System (CSS) cards. Two types of CSS cards are available: independent CSS cards and CSS cards integrated on the panel.

  • SFUs of the following models must have independent CSS cards installed in the following slots. Independent CSS cards are EH1D2VS08000 and ET1D2VQ06000 (CSS card ET1D2VQ06000 is supported since V200R012C00.).
    • Subcard slot in the ET1D2SFUA000 (supported on the S12704/S12708/S12712, which can have CSS card EH1D2VS08000 installed)
    • Subcard slot in the ET1D2SFUC000 (supported on the S12704/S12708, which can have CSS cards EH1D2VS08000 and ET1D2VQ06000 installed)
    • Subcard slot in the ET1D2SFUD000 (supported on the S12708/S12712, which can have CSS cards EH1D2VS08000 and ET1D2VQ06000 installed)
  • SFUs of the following model have integrated CSS cards.
    • ET1D2SFUB000 applicable to S12704/S12708/S12712 (supported since V200R010C00)
    • LSG7SFUBA200 applicable to S12704/S12708/S12712 (supported since V200R019C00)

Two member switches of the same or different models can form a CSS. For example, two S12704s can form a CSS; one S12708 and one S12712 can form a CSS.

Each chassis must have at least one MPU and one SFU installed. You are advised to install at least two SFUs and two CSS cards in each chassis. (An S12704 can have a maximum of two SFUs and two CSS cards installed.)

The SFUs in one chassis must be of the same model. The SFUs in two chassis can be of different models; however, the same model is recommended.

The CSS cards in one chassis must be of the same model. The CSS cards in two chassis can be of different models; however, the same model is recommended.

  • A CSS card supports hot swappable.
  • When installing a copper cable, optical module, or optical fiber, you can determine that it has been installed properly after hearing a click.
  • When removing a copper cable, optical module, or optical fiber, push its connector or handle slightly and then pull it out.
  • Ensure that the bend radius of the copper cables or optical fibers is greater than the minimum bend rand required. For more information, see the Hardware Description.

Tools and Accessories

  • ESD wrist strap or ESD gloves
  • Phillips screwdriver
  • Diagonal pliers
  • Cable ties
  • Labels

Procedure

  1. Wear an ESD wrist strap or ESD gloves. When wearing an ESD wrist strap, ensure that the ESD wrist strap is in a close contact with your wrist, and insert the other end in the ESD jack of a cabinet/rack.
  2. Install a CSS card in the subcard slot of each SFU, as shown in (Optional) Installing a CSS Subcard.
  3. Install the SFUs in SFU slots of each switch, as shown in Installing a Card.
  4. Attach number labels on both ends of the cluster cables.
  5. Connect the stack ports with cluster cables.
    • Cluster cable connections for EH1D2VS08000

    Each CSS card has eight SFP+ ports, which are divided into two groups. (Group 1 includes ports 1 to 4, and group 2 includes 5 to 8.) See the following 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.

    NOTE:
    • S12708 switches are used as an example here. Cable connections between S12704 and S12712 switches are the same.
    • One CSS card can only be connected to one CSS card in the other chassis but not the local chassis.
    • A port in group 1 of a CSS card can be connected to any port in group 1 of the CSS card on the other chassis. The requirements for ports in group 2 are the same.
    • At least one SFU needs to be installed in each chassis, and each SFU must have at least one cluster cable connected to the other chassis. To ensure reliability, you are advised to install two SFUs in each chassis and connect each SFU using at least two cluster cables.
    • It is recommended that CSS cards have the same number of cluster cables connected and that ports on CSS cards be connected sequentially based on their port numbers. If CSS cards have different numbers of cluster cables connected, the cluster bandwidth will decrease. If SFUDs are installed, it is recommended that CSS cards have an even number of cluster cables connected.

    NOTE:
    • S12708 switches are used as an example here. Cable connections between S12704 and S12712 switches are the same.
    • •Any port on any CSS card can be connected to any port in any CSS card of the other chassis, and one CSS card can be connected to only one CSS card in the other chassis.
    • At least one SFU needs to be installed in each chassis, and each SFU must have at least one cluster cable connected to the other chassis. To ensure reliability, you are advised to install two SFUs in each chassis and connect each SFU using at least two cluster cables.

If CSS cards have different numbers of cluster cables connected, the cluster bandwidth will decrease. If SFUDs are installed, it is recommended that CSS cards have an even number of cluster cables connected.

    • Cluster cable connections for ET1D2SFUB000

    NOTE:
    • S12708 switches are used as an example here. Cable connections between S12704 and S12712 switches are the same.
    • One CSS card can only be connected to one CSS card in the other chassis. It cannot be connected to different CSS cards in the other chassis or a CSS card in the local chassis.
    • If one chassis uses SFUB cards and the other chassis uses SFUA, only 4*10G ports on an SFUB card can be connected to the four ports in group 1 on a VS08 CSS card in the other chassis (in any sequence).
    • If one chassis uses SFUB cards and the other chassis uses SFUC or SFUD cards, 4*10G ports on an SFUB card can be connected to four ports in group 1 of the remote VS08 CSS card in any sequence; alternatively, 40GE ports on an SFUB card can be connected to six ports on the remote VQ06 CSS card in any sequence.
    • If the two chassis use SFUB cards, 4*10G ports on SFUB cards in the two chassis can be connected in any sequence, and 40G ports on SFUB cards in the two chassis can be connected.
    • At least one SFU needs to be installed in each chassis, and each SFU must have at least one cluster cable connected to the other chassis. To ensure reliability, you are advised to install two SFUs in each chassis and connect multiple cluster cables.

  6. Arrange the cables, route the cables through cable management frames, and bundle them with cable ties.

    NOTE:

    Keep the cable ties used to bundle cables on the same horizontal plane as the SFP+ ports to reduce the impact of gravity on these ports.

  7. Check the LINK indicator on the service cards. If the indicator is steady green, the ports are correctly connected.

    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.
