C9300-NM-2Y Overview
C9300-NM-2Y is a Cisco Catalyst 9300 uplink network module with two 25G/10G/1G SFP28 ports, giving compatible Catalyst 9300 switches a higher-speed modular uplink tier than 1G or 10G options. It installs in the Cisco Catalyst 9300 Series modular uplink slot and is supported only on Cisco Catalyst 9300 Series switches, not Catalyst 9300X-only network module bays. The module class is uplink, the host-side interface is Cisco's proprietary Catalyst 9300 network module slot, and the front-facing connectivity uses SFP28 cages for supported pluggable modules. C9300-NM-8X differs by eight 10GE SFP+ module slots.
25GbE per port provides the top documented link rate for this two-port module, while Cisco also lists 10G and 1G operation for the same SFP28 network module product family. Ethernet uplink traffic runs through the host Catalyst 9300 switching ASIC and Cisco IOS XE control plane, so VLAN trunks, routed interfaces, EtherChannel, QoS, and monitoring remain switch-level functions. SFP28 cages accept supported Cisco pluggable transceiver modules, with port identities appearing as TwentyFiveGigabitEthernet interfaces during configuration. C9300-NM-2Y uses no PCIe laneing, RAID logic, Fibre Channel controller, PoE delivery circuit, or cache memory.
C9300-NM-2Y slides into the Catalyst 9300 uplink slot with the module face up and is secured with captive screws; Cisco documents the network module as hot-swappable and requires supported network modules or a blank module to maintain proper platform operation. ORM Systems supplies this module in new and certified refurbished condition for access-layer uplink expansion, replacement, and spare-pool planning. Refurbished units receive contact inspection and functional validation in a compatible Catalyst 9300 chassis before dispatch. Request pricing for single-unit needs, matched optics, or volume deployments across repeated Catalyst 9300 access closets.
C9300-NM-2Y price is $1,400.00, a 53.7% saving from the Cisco list price of $3,022.00. C9300-NM-2Y is in stock and available for next-day dispatch. (terms applied)

C9300-NM-2Y Use Case
Access to Distribution 25G Handoff
C9300-NM-2Y installs in the modular uplink bay of a compatible Catalyst 9300 access switch and presents two 25GE SFP28 uplink slots toward distribution. Engineers connect supported SFP28 optics or DAC cables to upstream 25G ports, then configure trunks, routed links, or LACP EtherChannel according to the campus design. Endpoint traffic remains on the switch access ports while northbound traffic exits through dedicated high-speed uplinks. The result is a cleaner access-to-distribution handoff with more uplink bandwidth per closet.
Stacked Access Closet Uplink Standardization
In a stacked Catalyst 9300 wiring closet, C9300-NM-2Y gives selected stack members two 25GE SFP28 uplink interfaces for northbound connectivity. Operations teams standardize the module, optics, port numbering, and uplink templates across repeated closets, then apply consistent VLAN trunking, routing, or EtherChannel policies through Cisco IOS XE. Each stack keeps local endpoint switching inside the closet while using 25G links for aggregated traffic. The result is repeatable uplink planning across stack-based access deployments.
Campus Uplink Migration Point
The module occupies the Catalyst 9300 uplink position during a migration from lower-speed access uplinks to 25G distribution connectivity. Network teams replace the selected uplink module, install SFP28 links that match the upstream switch, and move routed or trunked handoffs onto the new 25GE interfaces. C9300-NM-2Y keeps the access switch chassis in service while the uplink layer changes around it. The result is higher northbound capacity without redesigning the endpoint access layer.
