Cisco C9300X-NM-8Y=

The Cisco C9300X-NM-8Y= is a hot-swappable, high-performance network module designed exclusively for Cisco Catalyst 9300X Series switches. The trailing "=" indicates it is a spare/replacement part—sold separately for field maintenance, upgrades, or expansion, rather than being bundled with new switches. It features 8 multi-rate SFP28 ports that support 1G, 10G, and 25G speeds, delivering flexible connectivity for enterprise campus and data center edge environments. With a total aggregate bandwidth of 200 Gbps (full-duplex), it balances performance, compatibility, and ease of maintenance, making it ideal for high-density access and server uplink scenarios.
