WHY CHOOSE THIS PRODUCT?

• High-density SFP expansion: 48 ports consolidate multiple optical or SFP-based connections into one Catalyst 9400 slot, helping maximize chassis capacity.
• 1G/10G flexibility: Configurable port speeds allow buyers to align connectivity with current requirements while supporting higher-speed network designs.
• 480 Gbps capacity: High aggregate bandwidth provides substantial traffic-handling headroom for enterprise switching workloads.
• Reduced maintenance impact: Hot-swappable installation enables line-card replacement or expansion without treating the module as a fixed chassis component.
• Enterprise traffic control: Hardware ACL acceleration and QoS queues support policy enforcement and traffic prioritization at scale.
• Operational visibility: NetFlow, SPAN, RSPAN, ERSPAN and DOM capabilities assist network monitoring and troubleshooting.
• Aggregation flexibility: LACP, PAgP and cross-module EtherChannel capabilities support resilient link aggregation architectures.
• Long-term platform value: Modular Catalyst 9400 deployment allows organizations to expand switching capacity without replacing the complete chassis.
