C9350-48U Description
The C9350-48U is a Cisco C9350 Series Smart Switch for dense wiring closets that power cameras, access points and building devices over 60W UPOE. The switch has 48 10M/100M/1G copper ports with IEEE 802.3bt Type 3 UPOE, a 2880W PoE budget, a modular uplink slot for up to 200G and 496 Gbps of switching capacity. The default 850W supply makes 625W available for PoE, and reaching the 2880W ceiling takes additional supplies.

Key Features
Each port supplies up to 60W under IEEE 802.3bt Type 3, for a 2880W ceiling when every port draws full power.
One 850W supply leaves 625W for PoE, a 1600W primary raises that to 1375W, and the 2880W ceiling needs a 1600W pair or three supplies.
Hot-swappable supplies fill up to three bays, which is where the extra PoE capacity comes from.
C9350-NM-2C, C9350-NM-8Y and C9350-NM-8M fit the slot, and C9350-NM-4C is not supported.
Up to eight C9350 members stack at 1.6 Tbps, with the supplies pooled across the stack.
The 48-port hardware maps to the Access Tier 1 Large Essentials or Advantage subscription, and IOS XE 17.18.1 boots at OS Advantage.
Application Scenarios
In a closet serving HD IP cameras, access control readers and intelligent lighting, the switch supplies 60W UPOE on each of 48 copper ports.
A campus floor with Wi-Fi access points that draw more than 30W can land them on the switch and run their traffic to the aggregation layer through the uplink module.
Several of the switches joined over StackWise-1.6T share power through StackPower+, so a powered stack can ride out the loss of one supply.

C9350-48U is the 60W UPOE model of this group: its 48 copper ports share a 2880W PoE budget under IEEE 802.3bt Type 3, while C9350-48P limits each port to 30W PoE+ on a 1440W budget and C9350-48T has no PoE. Closets that power only phones and access points fit C9350-48P, and closets with no powered devices fit C9350-48T. Cameras, displays and other devices that need 90W per port, multigigabit copper up to 10G, or 400G of uplink on C9350-NM-4C require C9350-48HX, which ships with a PWR-C2-1600WAC-I supply and a 4320W budget. C9350-48U takes C9350-NM-2C or C9350-NM-8Y for up to 200G of uplink.

Ordering Checklist
- Subscription tier: Order a Large Access Tier 1 (48 ports) subscription, LIC-CS-AC1-L-E (Essentials) or LIC-CS-AC1-L-A (Advantage), 36 months minimum. Match other stack members. IOS XE 17.18.1 boots at OS Advantage, so an Essentials order needs license boot level essentials.
- Uplink module: Add C9350-NM-2C or C9350-NM-8Y as a separate order line; C9350-NM-4C is not supported on this model. The base switch ships without an uplink module.
- Power supplies for PoE: Choose from default PWR-C2-850WAC-I, primary upgrade PWR-C2-1600WAC-IUP, and second or third supplies such as PWR-C2-850WAC-I/2 or PWR-C2-1600WAC-I/2. A single 850W supply gives 625W of available PoE, and the full 2880W needs a third supply.
- Power cords: Order one cord per power supply, such as CAB-TA-NA for 850W supplies or C9K-PWR-CAB-AC-EU for 1600W supplies. Each supply takes its own cord, and 1600W supplies use different cords from 500W and 850W supplies.
- Stacking cables: Select data cable STACK-T1A-50CM, STACK-T1A-1M or STACK-T1A-3M, and StackPower cable CAB-SPWR-35CM or CAB-SPWR-100CM. Stacking and StackPower cables are selected explicitly at order and do not ship by default.
