C9350-12Y is a managed Layer 3 fiber access switch with 12 fixed 25G SFP28 downlinks and a modular uplink bay in a rack-mount 1U chassis. The non-PoE configuration connects separately powered servers, storage equipment, and wireless controllers rather than powering copper endpoints. Cisco C9350 Series Smart Switches cover enterprise campus and branch access, with this fiber model addressing smaller aggregation points and compact server rooms. Uplink connectivity is selected independently from the downlinks: the bay accepts C9350-NM-2C, C9350-NM-8Y, or C9350-NM-8M, and the base switch does not include a module. C9350-24Y increases the fixed 25G fiber port count to 24 when more connections are required. Cisco IOS XE runs on the chassis, while licensing is selected separately rather than through a hardware license suffix.

1000 Gbps switching capacity defines the standalone bandwidth ceiling, while 744 Mpps forwarding rate identifies packet-processing throughput. 2600 Gbps switching capacity with stacking includes the stack interconnect rather than additional fixed front-panel ports. C9350-12Y combines 16 GB of DRAM and 18 GB of flash for control-plane operation and local software storage. Cisco Silicon One A100/L provides the forwarding silicon, while hardware scale reaches 64000 MAC entries and 192000 IPv4 routes; enabled routing features depend on the separately selected license. The fixed fiber downlinks also support 1G and 10G connections, allowing mixed-speed links within the same chassis. The Cisco C9350 management plane supports local console and SSH CLI access, Cisco Catalyst Center, and the Cisco Meraki dashboard. Three C9350-FAN-I= fan modules maintain front-to-back airflow with N+1 cooling redundancy, so rack airflow planning must accommodate the chassis ventilation direction.
Order C9350-12Y new sealed or certified refurbished, with up to 3-year extended warranty on new units and up to 1 year on certified refurbished units; 30-day returns cover every condition, with terms applying. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot, and optics bay recognition, with firmware verified and configurations wiped to factory default. Specify condition, quantities, licensing, and accessories on the purchase order. ORM Systems accepts POs and offers Net-30 for government, with RMA and advance replacement for enterprise and volume orders and regional stock/RMA support in UK, EU, US, and MEA.
| Key Specs | Key Spec Values |
|---|---|
Operating System | Cisco IOS XE |

Stacking | StackWise-1.6T / 8 members |
Cooling | 3 x C9350-FAN-I= fan modules |
When a lab or staging purchase must match the intended production software, C9350-12Y requires Cisco IOS XE 26.2.1 as its minimum software release. Do not standardize its staging image on an earlier release used by another family member; specify the required release and verification step before the PO.
When a multi-site purchasing program requires asset identification at receiving, the C9350 family includes an RFID module by default. The RFID module can be omitted through an explicit ordering choice, so decide whether the sites require that component and record any opt-out before submitting the PO.
When an existing C9350 installation needs shared power rather than additional independent feeds, StackPower+ permits a four-switch power ring. CAB-SPWR-35CM= and CAB-SPWR-100CM= are compatible power-sharing cable choices. Measure the connections and specify the power-ring cabling separately from data-stack cabling before the PO.
PoE-powered copper endpoint connections
C9350-12Y has no PoE-capable access ports. C9350-24P provides 24 Gigabit Ethernet PoE+ copper ports instead, rather than 12 fiber connections, for endpoints requiring power over Ethernet.
Four dedicated 100G uplinks
C9350-12Y limits modular uplink bandwidth to 200 Gbps and does not accept C9350-NM-4C. C9350-24Y supports C9350-NM-4C with four 100G uplinks but doubles the fixed fiber downlink count.

C9350-12Y identifies a Cisco C9350 switch with 12 ports of 25G fiber connectivity: C9350 names the series, 12 gives the fixed port count, and Y identifies the 25G fiber configuration. The PID carries no network license suffix; licensing and the optional uplink module are selected separately.
C9350-12Y supports local console and SSH CLI, Cisco Catalyst Center, and the Cisco Meraki dashboard. Cloud-sourced configuration provides dashboard management with a read-only cloud CLI; device-sourced configuration retains local control with read/write cloud CLI access. Select the management mode and licensing before ordering the hardware.
Cisco has not announced an end-of-sale date for C9350. C9350-12Y remains available as a member of the Cisco C9350 Series Smart Switches. A hardware order can specify this PID directly rather than substituting a successor identified by an end-of-sale announcement, while licensing and accessories remain separate selections.
ORM Systems offers C9350-12Y new sealed or certified refurbished, with up to 3-year extended coverage for new units and up to 1 year for refurbished units. Both conditions have 30-day returns; terms apply. Cisco's Limited Lifetime Warranty covers the original owner, limited to five years after discontinuance, and is separate from ORM's coverage.
C9350-12Y uses Cisco Switching Essentials LIC-CS-AC1-M-E or Cisco Switching Advantage LIC-CS-AC1-M-A through a Cisco Networking Subscription or Enterprise Agreement. A new subscription requires at least 36 months. The hardware PID does not fix a perpetual network license tier; specify the license separately with the hardware order.
No, C9350-12Y retains on-device operating system functionality when its switching subscription expires. Meraki dashboard and Catalyst Center management and monitoring become restricted, and subscription support is no longer available. Separate continued forwarding from continued access to management platforms when planning the renewal and support requirements.
C9350-12Y accepts C9350-NM-2C, C9350-NM-8Y, and C9350-NM-8M, with no uplink module included in the base switch. C9350-NM-2C supplies two 100G/40G connections; C9350-NM-8Y supplies eight 25G/10G/1G connections or four 50G connections. Select the required module and compatible optics to match the intended uplink connections.
The C9350 series supports eight-member StackWise-1.6T stacks operating at 1.6 Tbps, with all members using the same license level. Compatible data-stack cables are STACK-T1A-50CM=, STACK-T1A-1M=, and STACK-T1A-3M=. Select cable lengths for the physical arrangement; earlier-generation stacking cables are not compatible with the C9350 stack connectors.
The 12-port 25G fiber switch C9350-12Y ships with one PWR-C2-500WAC-I power supply, while its chassis supports three internal supplies. Redundancy is optional rather than standard. Specify an additional PWR-C2-500WAC-I/2 when redundant power is required, and select the regional power cable for each installed supply.
C9350-24Y provides 24 fixed 25G fiber downlinks, while C9350-12Y provides 12. Both configurations support 1G, 10G, and 25G downlink operation, so the distinction is the number of endpoint connections. C9350-12Y suits a smaller fiber connection requirement; C9350-24Y suits buyers needing more fixed fiber ports in one chassis.
C9350-24P supplies 30W PoE+ to copper endpoints, while C9350-12Y does not deliver PoE. Fiber-connected equipment on C9350-12Y therefore requires its own power source rather than receiving power through the switch connection. C9350-12Y suits separately powered fiber equipment; C9350-24P suits copper devices requiring power over Ethernet.
No, the C9350 25G fiber switch uses three C9350-FAN-I= fan modules rather than passive cooling. The cooling system provides N+1 redundancy and moves air from front to back. Allow for that airflow direction when selecting a rack position and specifying the surrounding equipment arrangement.
