Catalyst 9300 40GE module

The Cisco Catalyst 9300 network module adds two 40GE ports to a compatible Catalyst 9300 switch. It is designed for network teams that need additional high-speed uplink capacity in an existing chassis. The module installs in a dedicated network module slot on the switch.

Pre-installation checks

Verify that the Catalyst 9300 chassis has a free network module slot before ordering. Confirm the switch runs a software release that supports the module. Ensure the uplink cabling and optics match the 40GE interface requirements.

Upgrade context

This module replaces an empty slot or a lower-speed uplink module to increase aggregate uplink bandwidth. The jump is worth it when traffic growth demands more 40GE connectivity without replacing the entire switch.

Questions about this item

What comes in the box with the C9300-NM-2Q= module and what must be purchased separately?

The module includes two 40GE ports for Catalyst 9300 switches; compatible 40G transceivers and cables are sold separately.

How do I decide between the available versions of the Catalyst 9300 network module?

This model provides exactly two 40GE interfaces; choose it when you need a pair of 40G uplinks rather than a different port count.

What does the 40GE rating mean when the module is installed in a Catalyst 9300 switch?

Each of the two ports delivers 40 Gbps line-rate throughput for high-speed uplink connectivity.
