C9350-48HXN Description
The C9350-48HXN is a Cisco C9350 Series Smart Switch for 48-port access closets where only some endpoints need 10G but any port may need 90W UPOE+. The switch runs 12 Multigigabit ports at up to 10G and 36 at up to 5G, has 470W of PoE on its default 850W supply, and adds a 200G uplink slot and 1,000 Gbps of switching. The full 4320W budget takes three 1600W supplies on 200–240V input, and Cisco IOS XE 26.1.1a is the earliest supported release.

Product Performance
Key Features
Twelve downlinks negotiate up to 10G and the remaining 36 up to 5G, all starting from 10M, with 10M and 100M in full duplex only. Existing Cat5e carries 2.5G over the full 100 m; the 5G ports reach their top speed at that length on Cat6A. The twelve 10G ports need Cat6 for runs up to 55 m, or Cat6A out to 100 m.
The default 850W supply leaves 470W for PoE, enough for five ports at the full 90W. Higher budgets come from added supplies or a 1600W primary in the first bay, and 90W on every port takes 4320W.
A single Silicon One A100/L ASIC switches 1,000 Gbps and forwards 744 Mpps. The figure matches 300G of downlink capacity plus a full 200G uplink, counted in both directions, and the ASIC holds 18 MB of packet buffer.
Application Scenarios
On an office floor running two access point generations, Wi-Fi 7 units take the twelve 10G ports while Wi-Fi 6 and 6E units connect to the 5G ports. Every port delivers up to 90W of UPOE+.
Security teams run the IP cameras for a building from the UPOE+ ports and add power supplies as the camera count and wattage grow.
Smart building systems and IT/OT endpoints on the same floor draw power and network from the switch, sharing the closet with the access points.

C9350-48HXN differs from C9350-48HX in port speed and default power: 36 of its 48 ports top out at 5G, and its default 850W supply gives 470W of PoE. Closets with more than twelve 10G endpoints can move to C9350-48HX, which runs 10G on all 48 ports, takes 400G of uplink against 200G and starts at 1150W of PoE on 200–240V input. C9350-24HX runs 10G on every port as well and starts at 1265W on 200–240V input, which suits closets with no more than 24 high-power endpoints. Where endpoints link at 1G and draw 60W or less, C9350-48U provides UPOE on all 48 ports with a 2880W ceiling.

|
90W on the twelve 10G ports |
1080W: the 1600W primary alone (1220W) leaves 140W for the 36 5G ports, and a second 850W supply (1320W) leaves 240W |
|
30W on all 48 ports |
1440W, met by combinations such as a second 1600W supply (2070W) or a 1600W primary with any second supply |
|
60W on all 48 ports |
2880W: three supplies, for example 850W + 850W + 1600W (2920W) |
|
90W on all 48 ports |
4320W, reached only with three 1600W supplies; 3670W is the ceiling with the 850W unit in bay 1 |
|
Input voltage |
Budgets that include a 1600W supply assume 200–240V input; on 115V each 1600W supply delivers 1200W. The 850W supply is rated for 90V to 264V |
Ordering Checklist
- Subscription tier: Order the Access Tier 1 Large (48 ports) subscription, LIC-CS-AC1-L-E for Essentials or LIC-CS-AC1-L-A for Advantage, for a term of at least 36 months. Medium (up to 24 ports) SKUs do not match this switch.
- Uplink module: The base switch ships without a network module, so C9350-NM-2C, C9350-NM-8Y or C9350-NM-8M goes on the order as its own line. C9350-NM-4C and C9350-NM-8L are not supported on this model.
- Primary power supply: Select PWR-C2-1600WAC-IUP to replace the default 850W unit when one supply must carry more than 470W of PoE. Kept at the default, the 4320W ceiling is out of reach even with two more supplies.
- Second and third supplies: Add up to two supplies from PWR-C2-500WAC-I/2, PWR-C2-850WAC-I/2 and PWR-C2-1600WAC-I/2. Without them the budget stays at 470W, or 1220W with the 1600W primary on 200–240V input.
- 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: Pick one cord per supply, such as CAB-TA-NA for an 850W or 500W supply and C9K-PWR-CAB-AC-US for a 1600W supply. A supply ordered without its cord line arrives with no cord.
- 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.
