Arista CCS-758-X3-SC | 750X 8-Slot Switch Card Module, 1.6Tbps, Hot-Swap

Q: What is the purpose of the CCS-758-X3-SC switch card?
A: The X3 switch card is the central dataplane processing module for the CCS-758 chassis. It performs all Layer 2 and Layer 3 packet forwarding, VXLAN encapsulation, QoS, and security policy enforcement for connected line cards. Dual switch cards can be deployed for active-standby redundancy.

Q: Is this switch card compatible with the CCS-755 chassis?
A: No, the CCS-758-X3-SC is specifically designed for the 8-slot CCS-758 chassis. For the 5-slot CCS-755 chassis, you need the CCS-755-X3-SC switch card module instead.

Q: Can I hot-swap this switch card during operation?
A: Yes, the X3 switch card is hot-swappable and accessed from the rear of the chassis. In a redundant configuration with dual switch cards, you can replace the standby module without impacting network operations. Failover from active to standby occurs without control plane changes.

Q: How many switch cards does a CCS-758 chassis require?
A: A minimum of one X3 switch card is required for operation. For high availability deployments, two switch cards are recommended in an active-standby configuration, providing seamless failover and eliminating single points of failure.

Q: What line cards are supported by this switch card?
A: The X3 switch card supports all Arista 750X series line cards including 1G, 2.5G, 5G, and 10G PoE options. It handles packet processing for up to 8 line cards in the CCS-758 chassis, providing consistent features across all ports with fully shared buffer architecture.
