C9350-48P Description
The C9350-48P is a Cisco C9350 Series Smart Switch for campus access closets that power IP cameras, sensors and other PoE devices at up to 30W per port. The switch has 48 10M/100M/1G copper ports with 30W PoE+, 625W of PoE on its default 850W supply, a modular uplink slot for up to 200G and 496 Gbps of switching capacity. The full 1440W budget, enough for 30W on every port, needs a second 850W or 1600W supply.

Product Performance
Key Features
The default 850W supply leaves 625W for PoE, which covers 20 ports at a full 30W. A second 500W supply lifts the budget to 1125W, and a second 850W or 1600W supply reaches 1440W, the point where all 48 ports can draw 30W at once.
The default supply can be upgraded to a 1600W unit with PWR-C2-1600WAC-IUP, which gives 1375W of PoE from one supply and leaves two bays free. That supply delivers its full 1600W only on 180V to 264V input and is rated 1200W on 103.5V to 132V.
The slot ships empty and takes C9350-NM-2C for two 100G/40G QSFP28 ports, C9350-NM-8Y for eight 25G/10G/1G or four 50G SFP56 ports, or C9350-NM-8M for eight Multigigabit copper uplinks. Uplink bandwidth tops out at 200G on this switch, and the four-port C9350-NM-4C is not supported.
Up to eight C9350 switches stack over StackWise-1.6T at 1.6 Tbps, all at the same license level. StackPower+ pools the supplies of up to four switches on a 55V ring, so PoE load on one member can draw on power installed in another. Catalyst 9300 stack and StackPower cables do not fit.
Network Essentials or Advantage comes from a 48-port subscription, not from the hardware, and the switch boots at OS Advantage on Cisco IOS XE 17.18.1. Hardware IPsec arrives with Cisco IOS XE 26.2.1 and needs OS Advantage plus one HSECK9 key per switch.
The same hardware runs under Cisco Catalyst Center on premises or under the Meraki dashboard in the cloud. There is no regional or management-specific variant of the switch to choose.
Application Scenarios
In a building security closet, the switch powers fixed IP cameras on its 30W PoE+ ports and sends their streams to the recording servers over a 25G SFP56 uplink.
Office floor wiring closets connect desk phones and ceiling access points to the switch, which carries their power and traffic on the same Gigabit copper run of up to 100 m.
Facilities teams bring sensors and other low-power building devices onto a stack of these switches, with StackPower+ sharing supplies across members in the same closet.

C9350-48P and C9350-48T share 48 10M/100M/1G ports, a 200G uplink slot and 496 Gbps of switching, but C9350-48P adds 30W PoE+ on every port with 625W of PoE on its 850W supply, while the data-only model ships on a 500W supply and suits closets with no powered endpoints. Devices that draw more than 30W need C9350-48U, which carries 60W UPOE on all 48 ports and scales to 2880W with additional supplies; both PoE models start at the same 625W, so per-port wattage decides between them. Essentials or Advantage comes from the 48-port subscription rather than the hardware, and every stack member must run the same level.

Ordering Checklist
- Subscription tier: Add a 48-port Access Tier 1 subscription of at least 36 months, LIC-CS-AC1-L-E for Essentials or LIC-CS-AC1-L-A for Advantage. Switches on IOS XE 17.18.1 boot at OS Advantage, so Essentials needs license boot level essentials and a reload.
- Uplink module: Add C9350-NM-2C, C9350-NM-8Y or C9350-NM-8M as its own line. The base switch ships with an empty uplink slot, and C9350-NM-4C does not fit this model.
- Additional power supplies: Add PWR-C2-850WAC-I/2 or PWR-C2-1600WAC-I/2 when all 48 ports need 30W, or change the primary to PWR-C2-1600WAC-IUP. Without them the PoE budget stays at 625W.
- Stacking cables: Select STACK-T1A-50CM, STACK-T1A-1M or STACK-T1A-3M= and CAB-SPWR-35CM or CAB-SPWR-100CM for stacked switches. They do not ship by default, and Catalyst 9300 cables do not fit.
- Power cords: Select one cord for every supply, such as CAB-TA-NA, CAB-TA-EU or CAB-TA-UK for 500W and 850W supplies or C9K-PWR-CAB-AC-US for 1600W supplies. Each supply needs its own cord.
- HSEC key: Add one HSECK9 per switch when IPsec will run on it. IPsec needs OS Advantage and Cisco IOS XE 26.2.1 or later.
