Catalyst 9300 25GbE network module

The EVESKY C9300-NM-2Y is a hot-swappable network module that adds two 25 Gigabit Ethernet ports to a Catalyst 9300 Series switch. It accepts SFP28 transceivers for fibre or copper links and supports Layer 2 and Layer 3 switching, Quality of Service and MACsec or IPsec encryption. The module is suited for data-centre uplinks or high-speed server and storage connections.

Slot compatibility and transceiver choice

The module installs in a Catalyst 9300 network-module slot and can be inserted or removed without powering down the chassis. Each of the two ports requires an SFP28 transceiver matched to the link distance and media type, freeing the builder from fixed port speeds. No additional licensing is mentioned for the core switching features.

Sustained-load behaviour

With two 25 GbE ports active the module handles continuous line-rate traffic for Layer 2 and Layer 3 forwarding, QoS classification and MACsec or IPsec encryption. Hot-swap capability allows replacement during maintenance windows without interrupting other modules in the chassis. Dimensions are 12.13 x 5.75 x 3.94 inches.

Questions about this item

What is the maximum sustained throughput per port before the 25 GbE line rate becomes the bottleneck?

Each port operates at 25 GbE line rate, so sustained traffic above 25 Gbit/s per port will hit that limit first.

How much additional heat and fan noise does the module add when installed in a Catalyst 9300 chassis running continuously?

The module is passively cooled and draws power from the host chassis, so it adds minimal heat and no extra fan noise beyond what the switch already produces.

Which host switch and transceiver types are required for the module to function?

It requires a Catalyst 9300 Series switch with an available network-module slot and two SFP28 transceivers or compatible direct-attach cables.
