Cisco Catalyst 3650 Network Stacking Module

The Cisco C3650-STACK= is a plug-in module with a compact design that lets you link Cisco Catalyst 3650 switches into a single, high-bandwidth stack. By relying on Cisco StackWise-160 technology, it creates a unified fabric in which the member switches share a single control and data plane. The result is faster failover, easier management, and the freedom to expand your network without redesigning existing cabling or topology.

Installation is straightforward: insert the module into the designated slot on each Catalyst 3650 switch, connect the StackWise cables, and power up. Because the stack behaves like one logical switch, IT staff can push configurations, software updates, and security policies across every unit from a single interface. This approach reduces administrative overhead and minimizes the chance of configuration drift.

The module weighs just 3.88 oz, so it adds virtually no load to your rack. For growing offices, branch campuses, or any environment where uninterrupted connectivity matters, stacking helps maintain throughput and resilience even if one switch in the group loses power or requires maintenance. Businesses that demand predictable performance for voice, video, and data traffic will appreciate the way StackWise-160 allocates 160 Gbps of stack bandwidth to keep packets moving smoothly.
