C9350-24HX Description
The C9350-24HX is a Cisco C9350 Series Smart Switch for 24-port campus access closets that connect Wi-Fi 7 access points and other high-power endpoints over 10G copper. All 24 Multigigabit ports run from 10M to 10G with 90W UPOE+, and the switch adds 880 Gbps of switching, a 200G uplink slot and a 2160W PoE ceiling. On 200–240V input the default 1600W supply provides 1265W of PoE. Cisco IOS XE 26.1.1a is the first release that supports the switch.

Product Performance
Key Features
On 200–240V input the default 1600W supply gives 1265W for PoE, about 52W per port when all 24 ports draw power at once. Running every port at 90W takes 2160W, so a fully loaded closet needs added supplies.
Every downlink negotiates 10M, 100M, 1G, 2.5G, 5G or 10G, and the two lowest speeds run full duplex only. Existing Cat5e carries 2.5G over the full 100 m; 5G at that length needs Cat6A. Reaching 10G takes Cat6 for runs up to 55 m, or Cat6A out to 100 m.
A single Silicon One A100/L ASIC provides 880 Gbps of switching and 654.72 Mpps of forwarding. That capacity equals 24 ports at 10G plus a full 200G uplink, counted in both directions, and the ASIC carries 18 MB of packet buffer.
Application Scenarios
In a building wing served by its own small closet, Wi-Fi 6E and Wi-Fi 7 access points connect over 10G Multigigabit links, and each port delivers up to 90W of UPOE+.
Facilities teams connect building automation controllers and IT/OT endpoints to the UPOE+ ports, adding a power supply as more powered devices come online.
IP cameras covering a floor and its entrances take power and data from the switch, each over a single cable run.

C9350-24HX is the 24-port counterpart of C9350-48HX, with the same 90W UPOE+ on 10G Multigigabit ports and the same default 1600W supply but a 2160W PoE ceiling and 200G of uplink. Closets with more than 24 high-power endpoints can move to C9350-48HX, which adds 4320W of PoE on 200–240V input, 400G of uplink and 1,760 Gbps of switching. Where most access points link at 5G or below, C9350-48HXN gives 48 UPOE+ ports with 12 of them at 10G, though its default 850W supply leaves 470W for PoE. Closets of 60W devices on 1G links can drop to C9350-24U, which caps PoE at 1440W and switches 448 Gbps. A switch joining an existing C9350 stack must run the same license level as the other members.

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. Large (48 ports) SKUs do not match this switch.
- Uplink module: Add C9350-NM-2C, C9350-NM-8Y or C9350-NM-8M as its own line. The base switch ships without a module, and C9350-NM-4C and C9350-NM-8L are not supported on this model.
- Additional power supplies: Add up to two supplies from PWR-C2-500WAC-I/2, PWR-C2-850WAC-I/2 and PWR-C2-1600WAC-I/2 when the PoE load exceeds 1265W. Without them the budget stays at the default 1265W.
- Stacking cables: Select STACK-T1A-50CM, STACK-T1A-1M or STACK-T1A-3M= for a data stack, and CAB-SPWR-35CM or CAB-SPWR-100CM only for a StackPower+ ring. Neither ships by default, and Catalyst 9300 stack cables are not compatible.
- Power cords: Select one cord for every supply, such as C9K-PWR-CAB-AC-US for a 1600W supply or CAB-TA-NA for a 500W or 850W supply. Cords are not bundled, so each supply needs its own cord line.
- 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.
