The Cisco Catalyst C9300X-NM-8Y extends Catalyst 9300X campus switching with high-speed uplink capacity for access or compact aggregation stacks. Its eight 25G SFP28 ports help teams move beyond restrictive 10G links while preserving existing switch investments.
As access and aggregation layers absorb more traffic, uplink capacity has to keep pace without disrupting the switching base already in production.
The Cisco Catalyst C9300X-NM-8Y is an Uplink Network Module for Campus deployments that need a cleaner path to 25G connectivity. It adds eight 25G SFP28 ports to Catalyst 9300X stacks, making it a practical fit when the switch platform is still right, but the link design has become the constraint.
By extending an existing stack with dense 25G uplinks, the module supports faster aggregation and better headroom for server-room or high-performance access traffic. It lets teams keep the current switch base in place while moving away from restrictive 10G uplinks.
That approach helps preserve standardised designs, reduce unnecessary change, and align access layers with modern distribution speeds. It also gives infrastructure teams a straightforward way to add uplink capacity where production traffic is growing.
For environments planning the next step in uplink expansion, the Cisco Catalyst C9300X-NM-8Y offers a targeted upgrade path. Our team can help you assess fit and integrate it into your campus switching plan.
The Cisco Catalyst C9300X-NM-8Y is a network module for campus deployments that extends switching capacity and supports a scalable platform approach for enterprise access environments.
Modular Network Expansion
The module adds network expansion capability to a compatible Catalyst 9300X platform, supporting a flexible campus design.
25G SFP28 Connectivity
It provides 8 x 25G SFP28 ports to support high-speed uplink integration within campus switching architectures.
Access Layer Scaling
The modular form factor lets the platform scale connectivity without changing the underlying campus switch role.
Deployment Alignment
Its network-module design fits campus environments where additional uplink capacity is needed at the access or distribution edge.
Platform Continuity
As a Catalyst network module, it extends the existing switching platform rather than introducing a separate network function.
Capacity Planning
The 8-port, 25G configuration provides a defined expansion point for designing predictable campus connectivity.
Campus Integration
The module is intended for campus deployment use cases, helping align uplink design with enterprise network architecture.
If you are planning campus switch expansion or need to align uplink capacity with growth, our Cisco experts can help design the right Catalyst deployment approach.
Cisco Catalyst C9300X-NM-8Y is an uplink expansion module for Catalyst 9300X stacks where 25GbE aggregation is becoming the limiting factor. It fits access and management environments that need more headroom without replacing a working switch base.
In compact data centre access or management stacks, uplink pressure builds quickly as server-room traffic grows. The C9300X-NM-8Y adds dense 25G capacity so teams can keep the existing 9300X platform and avoid a disruptive switch refresh.
Finance teams need segmented connectivity for workstations, voice, payment systems and security appliances, with stable links that support audit and control requirements. This module gives 25G uplink room while preserving standardised Catalyst designs across the office estate.
Engineering labs and build rooms change fast, with test hosts, developer stations and large transfers all competing for bandwidth. Adding 25G uplinks to the 9300X stack prevents the access layer from becoming the bottleneck during peak activity.
Hospital access closets carry carts, phones, APs, cameras and clinical workstations, while patient and guest traffic must stay separated. The C9300X-NM-8Y expands uplink capacity without forcing a wider network rebuild in busy care areas.
Telecoms offices and operations rooms need dependable access for monitoring tools, voice services and support equipment across remote locations. This module strengthens uplink capacity on existing 9300X stacks while protecting installed switching investment.
Our team can help design and deploy Cisco Catalyst C9300X-NM-8Y uplink expansion for data centres, finance offices, development labs, healthcare sites and telecoms operations, aligned to your traffic profile, resilience needs and deployment standards.
