C3KX-NM-10GT Catalyst Network Modules

The C3KX network module family is specified for Cisco Catalyst 3750-X and 3560-X Series access switches. The C3KX-NM-10G option uses two 10 Gigabit Ethernet SFP+ ports, while the C3KX-NM-10GT option provides two 10GBASE-T copper ports. C3KX modules are not cross-compatible with later Catalyst generations such as the 3850 or 9300 series.

The C3KX-NM-10G is described as a hot-swappable uplink network module. It can be installed in the single front-facing module bay of a compatible Catalyst 3750-X or 3560-X switch without removing the chassis from the rack. Buyers should verify the exact part number, switch model, and installation requirements before replacing or upgrading an installed module.

The Cisco C3KX-NM-10G provides two 10 Gigabit Ethernet SFP+ ports. It is intended for compatible Catalyst 3750-X and 3560-X access switches and supports upgrades from existing access-switch uplinks to 10 Gigabit Ethernet. The C3KX-NM-10GT is a different family option with two 10GBASE-T copper ports, so these products should not be treated as interchangeable.

The product information identifies retrofitting an existing Gigabit-copper access closet with 10GbE uplinks as a common use case. This approach can add higher-speed uplink connectivity without replacing the compatible switch chassis. The required module depends on the uplink medium: C3KX-NM-10G uses SFP+ ports, while C3KX-NM-10GT uses 10GBASE-T copper ports.
