Cisco C9300-NM-4M | Catalyst 9300 4-Port Multigigabit Module, 100M/1G/2.5G/5G/10G RJ45

Q: Which Catalyst 9300 models are compatible with the C9300-NM-4M?
A: The C9300-NM-4M is compatible with all Cisco Catalyst 9300 and 9300X Series switches with modular uplink slots. It is also backward compatible with Catalyst 3850 Series switches. It is not compatible with fixed uplink models (C9300L SKUs).

Q: What speeds does the C9300-NM-4M support and what cabling is required?
A: The module supports 100Mbps, 1G, 2.5G, 5G, and 10G speeds with auto-negotiation. Cat 5e supports speeds up to 5Gbps, while Cat 6 or Cat 6a is recommended for full 10Gbps performance over distances up to 100 meters.

Q: Can the C9300-NM-4M be installed without powering down the switch?
A: Yes, the C9300-NM-4M is hot-swappable and field-replaceable, allowing installation and removal without downtime or disruption to switch operations.

Q: Does the C9300-NM-4M provide Power over Ethernet to connected devices?
A: No, the C9300-NM-4M is an uplink expansion module and does not deliver PoE. It is designed for high-speed uplink connections to other switches, wireless controllers, or servers.

Q: What are the typical use cases for the C9300-NM-4M?
A: Common deployments include Wi-Fi 6/6E access point aggregation, high-speed uplinks to core or distribution switches, server connectivity, and campus network expansion requiring multigigabit copper uplinks without the need for fiber transceivers.
