C9350-48HX Description
The C9350-48HX is a Cisco C9350 Series Smart Switch for stackable campus access closets that power high-draw endpoints over 10G copper. The switch has 48 Multigigabit ports running from 10M to 10G, all with 90W UPOE+, a 1150W PoE budget on its default 1600W supply, a 400G modular uplink slot and 1760 Gbps of switching capacity. Full 90W on every port takes 4320W, a budget that only three 1600W supplies reach.

Product Performance
Key Features
On the default 1600W supply the switch has 1150W for PoE, enough for 12 ports at the full 90W or 38 ports at 30W. A second 1600W supply raises the budget to 2750W, and the 4320W needed for 90W on all 48 ports takes a third 1600W supply.
The default PWR-C2-1600WAC-I delivers 1600W only on 180V to 264V input. On a 103.5V to 132V circuit the same supply is rated at 1200W, so the closet’s electrical feed decides how much of the rating is available.
All 48 ports negotiate 10M, 100M, 1G, 2.5G, 5G or 10G, with 10M and 100M limited to full duplex. Cat5e carries a port up to 5G; 10G needs Cat6 for runs up to 55 m or Cat6A for the full 100 m.
The slot reaches 400 Gbps with C9350-NM-4C, four 100G/40G QSFP28 ports, or C9350-NM-8L, eight 50G SFP56 ports. It also takes C9350-NM-2C, C9350-NM-8Y and C9350-NM-8M when 200G of fiber or eight Multigigabit copper uplinks are enough.
Two Silicon One A100/L ASICs give the switch 1760 Gbps of switching capacity and 1309.44 Mpps of forwarding. That figure equals 48 ports at 10G plus 400G of uplink in both directions, and each ASIC adds 18 MB of packet buffer for 36 MB in total.
Up to eight C9350 switches stack over StackWise-1.6T at 1.6 Tbps, and every member runs the same license level. StackPower+ joins up to four switches in a 55V ring, where the supplies of all members form one power pool.
Application Scenarios
On an office floor equipped with Wi-Fi 6E or Wi-Fi 7 access points, each access point draws its 10G Multigigabit link and up to 90W of UPOE+ from the same port. Traffic leaves the closet over a 100G uplink module.
A smart building closet feeds IoT devices and other high-power endpoints from the 90W UPOE+ ports, adding power supplies as more of those endpoints come online.
Small campuses without a separate distribution layer can run a stack of these switches as a collapsed core, with local endpoints on the copper ports and 100G QSFP28 links to the other wiring closets.

C9350-48HX and C9350-48TX share the same 48 10G Multigigabit ports, 400G uplink options and 1760 Gbps of switching, but C9350-48TX is data only on a 500W supply, so it fits closets with no powered devices. C9350-48HXN keeps 90W UPOE+ on all 48 ports but runs only 12 of them at 10G and 36 at 5G, with 200G of uplink and 470W of PoE on its default 850W supply. Floors where most access points link at 5G or below can move to it. Closets that power 60W devices over 1G links can drop to C9350-48U, which tops out at a 2880W budget and 200G of uplink. None of these hardware PIDs carries a license tier: Essentials or Advantage comes from the 48-port subscription, and every stack member must share one level.

Ordering Checklist
- Subscription tier: Order a 48-port Access Tier 1 subscription, LIC-CS-AC1-L-E for Essentials or LIC-CS-AC1-L-A for Advantage, for at least 36 months. Switches on IOS XE 17.18.1 boot at OS Advantage, so an Essentials order needs license boot level essentials and a reload.
- Uplink module: Add C9350-NM-4C, C9350-NM-2C, C9350-NM-8Y, C9350-NM-8M or C9350-NM-8L as its own line. The base switch ships without an uplink module.
- Additional power supplies: Add up to two more supplies such as PWR-C2-1600WAC-I/2. Without them the PoE budget stays at 1150W on the default supply.
- Power cords: Select one cord for every supply, such as C9K-PWR-CAB-AC-US or C9K-CAB-US520PC21 for 1600W supplies and CAB-TA-NA for 500W or 850W supplies. Each supply needs its own cord.
- Stacking cables: Select STACK-T1A-50CM, STACK-T1A-1M or STACK-T1A-3M= and CAB-SPWR-35CM or CAB-SPWR-100CM explicitly. They are not included by default, and Catalyst 9300 stack cables do not fit.
- 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.
