C9350-48U Description
C9350-48U is a Cisco C9350 Series stackable enterprise access switch for high-density copper access with UPOE. It provides 48 10M/100M/1G copper downlink ports, UPOE / IEEE 802.3bt Type 3 support with up to 60W per port, a 2880W maximum PoE power budget, and 570W available PoE with the default PWR-C2-850WAC-I power supply. The hardware scope includes three power-supply slots, three fan modules, SSD support up to 240 GB, and modular uplink support up to 200G with C9350-NM-2C or C9350-NM-8Y. The switch supports access-layer deployments that need 48 copper ports with high-power PoE and flexible uplink modules.

Key Features
C9350-48U fits access closets where most endpoints still use 1G copper but require more power than standard PoE+ can provide. It is useful for security, building automation, and workplace infrastructure that needs 60W power classes.
The switch supports C9350-NM-2C and C9350-NM-8Y uplink modules, letting engineers choose between 40G/100G QSFP28 uplinks or SFP56-based 1G/10G/25G/50G uplink designs.
StackWise-1.6T helps buyers scale multiple access switches under one operational stack, reducing management overhead in larger campus or branch deployments.
The C9350 platform supports three internal power supply module slots, which matters when the PoE load is higher than the default 850W PSU can cover.
C9350 runs Cisco IOS XE and supports modern management, automation, telemetry, and application-hosting capabilities that align with current Cisco campus operations.
Choose C9350-48U when the endpoints need 1G copper and 60W UPOE, but not 2.5G/5G/10G multigigabit access. This avoids overbuying a C9350-48HX or C9350-48TX class switch.
Application Scenarios
Use C9350-48U when a wiring closet needs 48 RJ-45 access ports for 1G devices and a higher PoE class than 30W PoE+. It solves the common buyer problem of powering cameras, sensors, access control, and lighting without moving to a multigigabit access switch.
Choose this SKU for buildings where many endpoints are 1G but need 60W UPOE, including HD IP cameras, access control equipment, PoE sensors, and intelligent lighting. The switch gives procurement teams a clearer fit than data-only or 30W PoE+ models.
C9350-48U works for refresh projects that need 1G access today with room to select 100G/40G or 25G/50G uplink modules. It helps engineers plan uplink capacity separately from downlink and PoE requirements.

- Choose C9350-48U when the project needs 48 x 1G copper access with 60W UPOE per port.
- Choose C9350-48P when 30W PoE+ is enough and the project does not need 60W UPOE.
- Choose C9350-48T when no PoE is required and the access layer is data-only.
- Choose C9350-48HX when endpoints require multigigabit access or 90W UPOE+.
Selection Guide
1. Choose C9350-48U for 1G endpoints that need 60W PoE
Select C9350-48U when endpoint speed is 1G but powered-device demand is above standard PoE+ levels. It is stronger than C9350-48P for 60W devices and more cost-controlled than C9350-48HX when multigigabit access is not required.
2. Choose C9350-48P or C9350-48T for lower power requirements
If the site only needs 30W PoE+, compare C9350-48P. If the site is data-only, compare C9350-48T and avoid paying for PoE capacity that will not be used.
3. Choose C9350-48HX for Wi-Fi 7 or 10G mGig access
If the project involves Wi-Fi 6E/7 access points, 2.5G/5G/10G copper access, or 90W UPOE+, C9350-48HX is the more appropriate model.
4. Verify power, uplink, and license before ordering
Confirm the PoE budget against the real endpoint load, select C9350-NM-2C or C9350-NM-8Y for uplinks, and choose the correct Cisco Switching Essentials or Advantage license tier for a 48-port access switch.
