The Cisco Catalyst C9300-NM-2Y extends Catalyst 9300 campus switching with targeted uplink expansion for busy access closets and small aggregation points. Its two 25G SFP28 uplink slots add higher-speed headroom while preserving the existing switch investment and avoiding a wider network refresh.
As access layers carry more traffic from endpoints, servers and shared services, uplink capacity can become the point where growth, segmentation and performance all meet.
The Cisco Catalyst C9300-NM-2Y is an Uplink Network Module for Campus environments that need a focused step up in backbone capacity. It adds 2×25G SFP28 uplink slots to compatible Catalyst 9300 switches, helping existing stacks support denser access traffic without changing the switch platform.
Its role is straightforward: give the access layer more headroom where 10G uplinks are no longer enough, while keeping the current switch base in place. That makes it a practical fit for busy closets, aggregation points and controlled campus segments where link design needs to keep pace with the workload.
For infrastructure teams, that means a cleaner way to add uplink bandwidth, preserve standardised switching designs and avoid unnecessary platform replacement. The result is a more balanced access layer that is easier to scale and better aligned to operational demand.
Talk to our team about the Cisco Catalyst C9300-NM-2Y and how it can fit your campus switching plan.
The Cisco Catalyst C9300-NM-2Y is a campus network module that extends switching capacity with compact high-speed uplink connectivity for enterprise edge deployments.
Modular Network Integration
The module adds network expansion capability to the Cisco Catalyst C9300 platform, allowing the switch to adapt uplink requirements within a campus architecture.
High-Speed Fiber Connectivity
It provides two 25G SFP28 ports to support high-bandwidth uplink design in environments that need compact, fast interconnects.
Campus Deployment Fit
Its design aligns with campus switching roles where modular uplink capacity helps connect access, aggregation, and distribution layers.
Platform Level Flexibility
The module supports a scalable architecture that lets the switching platform be configured for changing network connectivity needs.
Operational Continuity
Modular uplink expansion helps maintain service continuity by keeping connectivity options aligned to the switch platform rather than requiring a separate device.
Deployment Consistency
The network module form factor supports consistent integration into the Cisco Catalyst C9300 switching environment for standardized campus builds.
Connectivity Planning
The two 25G SFP28 interfaces provide a clear uplink option for designing predictable campus interconnect capacity.
If your campus design needs modular high-speed uplinks, our Cisco experts can help align this network module with your switching architecture and growth plans.
Cisco Catalyst C9300-NM-2Y is a 25GbE uplink expansion option for compatible Catalyst 9300 switches in high-demand access and aggregation stacks. It fits teams that need more uplink headroom without replacing a switch platform that still meets the site standard.
In hospital closets carrying carts, phones, APs and cameras, uplinks can become the first constraint as traffic grows. This module adds two 25G uplinks to keep clinical, admin and guest traffic moving without a wider network refresh.
Finance teams often need auditable switching designs that can support segmented users, voice, payment and service systems. The C9300-NM-2Y gives selected Catalyst 9300 stacks a controlled jump beyond 10G while preserving the existing platform and standard operating model.
Developer labs and test spaces change quickly, with build traffic, lab hosts and temporary kit placing uneven pressure on access uplinks. Adding two 25G links helps remove bottlenecks without forcing a full redesign of the switching estate.
Compact data centre stacks often need predictable headroom for management, out-of-band access and server-room links kept separate from production traffic. This module extends the useful life of Catalyst 9300 deployments where higher-speed uplinks are the immediate requirement.
Media teams move large files between edit suites, review rooms and shared storage, so access links need to absorb bursts without slowing collaboration. The C9300-NM-2Y adds fibre capacity at the edge while retaining the installed switch base.
We can help design and deploy the right Catalyst 9300 uplink expansion for healthcare, finance, software development, data centre and media environments, aligned to traffic patterns, resilience needs and existing switching standards.
