Cisco C9300-NM-4G | 4-Port 1G SFP Network Module for Catalyst 9300

Q: Which Catalyst 9300 switches are compatible with the C9300-NM-4G?
A: The C9300-NM-4G is compatible with Cisco Catalyst 9300 Series switches that have modular uplink capabilities (C9300 and C9300X SKUs). It is not compatible with fixed uplink models (C9300L SKUs). The module is also backward-compatible with Catalyst 3850 network module slots on C9300 switches.

Q: Can I install this module while the switch is running?
A: Yes, the C9300-NM-4G is hot-swappable and field-replaceable, meaning it can be installed or removed without powering down the Catalyst 9300 switch, minimizing network downtime during upgrades or maintenance.

Q: What type of transceivers does the C9300-NM-4G support?
A: The module supports standard Cisco 1G SFP transceivers with LC fiber connectors, compatible with both single-mode and multimode fiber options. This allows flexibility in choosing the appropriate optics based on distance and deployment requirements.

Q: Is the C9300-NM-4G included with the switch purchase?
A: No, network modules are sold separately and are not included in the default Catalyst 9300 switch configuration. You can select the appropriate network module based on your uplink requirements at the time of purchase or add it later as your network grows.

Q: What are typical use cases for the C9300-NM-4G module?
A: The module is ideal for adding fiber uplinks to connect Catalyst 9300 access switches to distribution layer switches or core routers, extending network reach beyond copper limitations, and providing redundant uplink paths for high-availability enterprise campus networks.
