Ideal Use Cases
Campus Distribution Layer Uplinks
Adds two 10GbE uplinks to a Catalyst 3850 acting as a campus distribution switch, providing the bandwidth headroom needed to aggregate multiple access-layer stacks without creating bottlenecks.
Catalyst 3850 Stack Uplink Expansion
Extends uplink capacity in stacked Catalyst 3850 environments running StackWise-480, allowing the stack to connect at 10GbE speeds to core or distribution-layer infrastructure.
Fiber Uplink Connectivity
Supports a range of 1G and 10G SFP and SFP+ optics, making this module well suited for deployments that require fiber uplinks across buildings or to a data center interconnect.
Enterprise Access Layer Aggregation
Ideal for access-layer switches that need higher-speed uplinks to handle the traffic load from high-density PoE or multi-gigabit downlink port configurations.
Spare and Replacement Module Inventory
A cost-effective option for network operations teams maintaining spares for Catalyst 3850 deployments, ensuring fast recovery from module failure without the lead time or cost of new hardware.
