Catalyst 9300 Series 40G Network Module
Product Description
The Cisco C9300‑NM‑2Q is a high‑performance uplink network module designed for use with **Cisco Systems Catalyst 9300 Series switches. It enhances the uplink connectivity of access‑layer switches by providing two 40 Gigabit Ethernet QSFP+ ports, delivering ultra‑fast data transport for aggregation, core connectivity, or inter‑switch links in enterprise and campus networks. This hot‑swappable module enables simple expansion of network capacity without replacing the entire switch, offering flexibility and scalability for growing network demands.
