C9350-12Y Description
The C9350-12Y is a Cisco C9350 Series Smart Switch for compact server rooms and small aggregation layers that link servers, storage and access switches over fiber. The switch carries 12 SFP28 ports at 1G, 10G or 25G on a single Silicon One A100/L ASIC, a modular uplink slot of up to 200G and 1,000 Gbps of switching capacity. Support for the switch begins with Cisco IOS XE 26.2.1, and its fiber ports carry data only, with no PoE.

Product Performance
Key Features
Each of the 12 SFP28 ports runs at 1G, 10G or 25G. Servers on 25G adapters, storage on 10G and older 1G fiber links can land on the same switch without a separate port group for each speed.
The Silicon One A100/L ASIC switches 1,000 Gbps, enough for all 12 ports at 25G plus a full 200G uplink counted in both directions. Northbound, 300G of SFP28 traffic is 1.5:1 over a 200G uplink module, and the ASIC buffers bursts in 18 MB of packet memory.
The uplink slot takes C9350-NM-2C for two 100G/40G QSFP28 ports, C9350-NM-8Y for eight 25G/10G/1G or four 50G SFP56 ports, or C9350-NM-8M for eight Multigigabit copper ports at up to 80 Gbps. All three are hot-swappable.
Inside a StackWise-1.6T stack of up to eight C9350 switches, the 1.6 Tbps stack link lifts this switch to 2,600 Gbps of switching capacity. Copper and fiber models can share a stack at the same license level. A stack of Multigigabit access switches can therefore take this switch as its fiber aggregation member under a single management plane.
With no PoE to feed, the default 500W supply runs the switch alone. The two empty bays accept a second or third supply for N+1 redundancy, and the supplies do not have to match in wattage.
With the default 500W supply or an 850W supply, the 1RU switch is 42 cm (16.5 in.) deep. A 1600W supply extends the depth to 50.1 cm (19.7 in.), so the supply choice sets how deep the rack or cabinet has to be.
Application Scenarios
A compact server room connects its servers and storage arrays to the 25G SFP28 ports and reaches the campus core through a 100G QSFP28 uplink module.
In a small campus, the switch collects the 10G and 25G fiber uplinks from access closets in each building and passes the combined traffic to the core over its uplink slot.
Branch offices place their wireless controller and local servers on the fiber ports, giving each device a 10G or 25G link to the rest of the site.

C9350-12Y and C9350-24Y share 1G/10G/25G SFP28 ports, but C9350-12Y puts 12 ports on one ASIC with a 200G uplink slot and 1,000 Gbps. C9350-24Y doubles that to 24 ports on two ASICs, with a 400G slot and 2,000 Gbps. Rooms that need more than 12 ports at 25G, or four 100G uplinks on C9350-NM-4C, need the two-ASIC model, which stays on the Medium (up to 24 ports) subscription tier. Where the fiber runs only need 1G, C9350-24S gives 24 SFP ports at 448 Gbps from IOS XE 26.1.2. C9350-48S gives 48 at 496 Gbps from the same release and moves to the Large (48 ports) tier.
Ordering Checklist
- Subscription tier: Select LIC-CS-AC1-M-E or LIC-CS-AC1-M-A, the Access Tier 1 Medium (up to 24 ports) subscription, with a term of 36 months or longer. Large (48 ports) SKUs do not match this switch.
- Uplink module: Put C9350-NM-2C, C9350-NM-8Y or C9350-NM-8M on the order as its own line. The switch ships without an uplink module.
- Second power supply and cords: Add PWR-C2-500WAC-I/2, PWR-C2-850WAC-I/2 or PWR-C2-1600WAC-I/2 for N+1 redundancy, plus one cord per supply, such as CAB-TA-NA for a 500W or 850W unit and C9K-PWR-CAB-AC-US for a 1600W unit. Cords are not bundled with any supply.
- Stacking cables: A data stack needs STACK-T1A-50CM, STACK-T1A-1M or STACK-T1A-3M=, and none ship with the switch. Add CAB-SPWR-35CM or CAB-SPWR-100CM only when members will share power over StackPower+. Catalyst 9300 stack and StackPower cables are not compatible.
- SSD storage: Select the SSD option during ordering when hosted applications need local storage, up to 240 GB in the USB 3.0 slot. An order without that selection ships with no SSD.
- HSECK9 for IPsec: IPsec needs OS Advantage and one HSECK9 per switch, every stack member included. Give Cisco the Smart Account and Virtual Account at order so SLAC is factory-installed; Catalyst Center cannot generate SLAC for this series.
