C9300-NM-2Q Description
The C9300-NM-2Q is a Cisco Catalyst 9300 Series hot-swappable uplink network module for C9300 modular-uplink access switches. The module has two 40 Gigabit Ethernet QSFP+ slots, and each 40G port can split into four 10G interfaces with a 4x10G breakout cable. It works only in the C9300 switches that its network module compatibility table lists, because Catalyst 9300X models take C9300X-NM modules instead.

Application Scenarios
A wiring-closet Catalyst 9300 access switch uses the two QSFP+ slots to reach distribution switches at 40G.
Where the upstream switch offers 10G ports, a 4x10G breakout cable turns one 40G slot into four 10G links, and two cables give TenGigabitEthernet1/1/1 through 1/1/8.

C9300-NM-2Q is the 2-port 40G QSFP+ network module for Catalyst 9300 modular-uplink switches, against C9300-NM-2Y with two 25G SFP28 slots that also take SFP and SFP+ optics. Uplinks planned around 25G, 10G or 1G optics therefore need C9300-NM-2Y, and eight 10G/1G SFP+ slots need C9300-NM-8X, which is also the module a C9300 switch order carries by default. Four 1G SFP uplinks call for C9300-NM-4G, which does not accept SFP+. Sites running Catalyst 9300X switches cannot use any of these modules and need the C9300X-NM family, such as C9300X-NM-2C.
Ordering Checklist
- Catalyst 9300 hosts: Check the exact switch SKU against the C9300-NM-2Q entry in the Catalyst 9300 network module compatibility table, for example C9300-24P-E and C9300-24H-E. Membership in the Catalyst 9300 family does not by itself confirm that a sub-series takes this module; the slot accepts C9300 modules only.
- Catalyst 9300X and 9300L: Do not order for C9300X switches, which take C9300X-NM modules, or C9300L models, which have fixed uplinks. Neither switch family has a slot that accepts this module.
