Cisco Catalyst 9300 C9300X-NM-8Y= 8 x 10G/25G Module | SFP+/SFP28

Extend Catalyst 9300 switching capacity with an 8 x 10G/25G network module designed for SFP+/SFP28 uplinks. This module gives infrastructure teams a clean path to add high-speed connectivity without replacing the switch platform, making it a practical choice for campus aggregation, server access, and high-throughput edge designs. The 8-port layout supports dense uplink planning where port count, speed flexibility, and chassis consistency matter. By supporting both 10 GbE and 25 GbE optics, it helps teams match link speed to workload demand while keeping deployment options open for mixed environments. That flexibility is valuable when you need to standardize on a single switch family but still accommodate different uplink tiers across closets or aggregation points. As a spare module, it also supports operational continuity. Keeping a qualified replacement on hand reduces recovery time when a module fails and helps protect service levels in environments where switch downtime is not acceptable. For organizations that have already standardized on Catalyst 9300, this module preserves the platform investment while adding the bandwidth headroom required for growth.
