Cisco C9300X-NM-2C=

The Cisco Catalyst C9300X-NM-2C= is a 2-port 40G/100G QSFP+/QSFP28 hot-swappable network module designed exclusively for Cisco Catalyst 9300X Series switches. The trailing = signifies this is a standalone spare/replacement SKU for field upgrades, expansion, or hardware maintenance.
This high-speed module delivers 200 Gbps full-duplex aggregate bandwidth to address demanding enterprise core, aggregation, and data center edge connectivity requirements.

Features & Benefits

Dual-Rate High-Speed Uplinks: 2 x QSFP28 ports supporting 100 Gbps (100GBase-X) and 40 Gbps (40GBase-X) dual-speed operation.
Total Aggregate Bandwidth: 200 Gbps full-duplex for high-performance, non-blocking switching.
Hot-Swappable Design: Fully field-replaceable without powering down the switch, ensuring zero network downtime.
Wide Media Compatibility: Supports all standard Cisco QSFP+ (40G) and QSFP28 (100G) optical transceivers (SR4, LR4, ER4), direct-attach copper (DAC) cables, and active optical cables (AOC).
Hardware-Based Security: Leverages the Catalyst 9300X's UADP 2.0sec ASIC to enable line-rate 100G IPsec encryption for secure data transit.
Investment Protection: Seamlessly supports existing 40G infrastructure while enabling a clear path to 100G migration.
Spare Part SKU: Identical hardware performance to the standard C9300X-NM-2C, packaged and sold separately for serviceability.
