C9350-24S Description
The C9350-24S is a Cisco C9350 Series Smart Switch for fiber access in branch offices and smaller campus buildings. The switch has 24 1G SFP downlinks, 448 Gbps of switching capacity on one Silicon One A100/L ASIC and a modular uplink slot for up to 200G. None of the ports supply PoE, and Cisco IOS XE 26.1.2 is the minimum software release.

Product Performance
Key Features
Every access port is a 1G SFP slot. The optic fitted in each slot sets the reach and fiber type of that port.
Once auto-off is enabled, the switch keeps the SerDes of an SFP port off until it detects a module. Ports held in reserve for later growth then save energy, and a separate setting keeps the port LEDs dark until a link event.
C9350-NM-2C adds two 100G/40G QSFP28 ports, C9350-NM-8Y adds eight 25G/10G/1G or four 50G SFP56 ports, and C9350-NM-8M adds eight Multigigabit RJ-45 ports at up to 80 Gbps. Each module is hot-swappable.
One Silicon One A100/L ASIC switches 448 Gbps and forwards 333.312 Mpps. The 448 Gbps figure equals the 24 ports at 1G plus a full 200G uplink, counted in both directions.
StackWise-1.6T joins up to eight C9350 switches at 1.6 Tbps, and copper and fiber models can share a stack when every member runs the same license level. Up to four members can also pool their supplies over a 55V StackPower+ ring.
The chassis has three supply bays and ships with one 500W unit. With no PoE load to feed, a second or third supply adds redundancy, and the supplies can run in N+1 redundant mode instead of the default combined mode.
Application Scenarios
A branch office that cables its desks and equipment rooms with fiber can terminate up to 24 1G links on the switch and carry them to the WAN edge through the uplink module.
In a smaller campus building, security closets, labs and an adjoining annex sit too far away for copper, so their fiber runs come back to the switch, which hands the traffic to the distribution layer.
On a production floor or beside heavy electrical equipment, controllers and workstations connect to the SFP ports over fiber, which keeps their links clear of electromagnetic interference.

C9350-24S and C9350-24T share 448 Gbps of switching and the 200G uplink slot, but C9350-24S puts 1G SFP fiber on its 24 downlinks where the copper model has 10M/100M/1G RJ-45 ports. Sites that wire endpoints with copper cabling take C9350-24T instead. Fiber links that must run at 10G or 25G call for C9350-24Y, which switches 2,000 Gbps and accepts C9350-NM-4C and C9350-NM-8L for uplinks up to 400G. More than 24 1G fiber links point to C9350-48S, which doubles the SFP count at 496 Gbps and moves to the Large (48 ports) subscription tier.
Ordering Checklist
- Subscription tier: Order the Access Tier 1 Medium (up to 24 ports) subscription, LIC-CS-AC1-M-E for Essentials or LIC-CS-AC1-M-A for Advantage, for at least 36 months. An Essentials order also needs license boot level essentials set and a reload.
- Uplink module: Add C9350-NM-2C, C9350-NM-8Y or C9350-NM-8M as its own line. The switch ships with an empty slot, and C9350-NM-4C and C9350-NM-8L are not supported on this model.
- SFP optics: Add a 1G SFP transceiver for every downlink that will carry a link. The switch comes with its 500W supply, an RFID module and two 19-inch rack brackets, but no optics.
- Additional power supplies: Add PWR-C2-500WAC-I/2, PWR-C2-850WAC-I/2 or PWR-C2-1600WAC-I/2 when the switch needs supply redundancy. Only the default supply ships, and a 1600W supply makes the switch 21.1 in. (53.6 cm) deep instead of 17.9 in. (45.6 cm).
- Stacking cables: Select STACK-T1A-50CM, STACK-T1A-1M or STACK-T1A-3M= for the data stack and add CAB-SPWR-35CM or CAB-SPWR-100CM StackPower+ cables only for power sharing. None ships by default, and Catalyst 9300 stack and StackPower cables are not compatible with C9350 switches.
- Power cords: Choose one cord per supply for the destination country, such as CAB-TA-NA, CAB-TA-EU or CAB-TA-UK for a 500W or 850W supply and C9K-PWR-CAB-AC-US for a 1600W supply. Cords are not bundled with the supplies.
- HSECK9 for IPsec: IPsec needs OS Advantage, Cisco IOS XE 26.2.1 or later 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.
