C9350-48TX Description
The C9350-48TX is a Cisco C9350 Series Smart Switch for campus access closets that connect 10G copper endpoints without powering them. The switch has 48 Multigigabit ports running from 10M to 10G with no PoE, a modular uplink slot for up to 400G and 1760 Gbps of switching capacity on two Silicon One A100/L ASICs. Ports reach 10G only over Cat6 runs up to 55 m or Cat6A up to 100 m, while Cat5e cabling stops at 5G.

Product Performance
Key Features
Each of the 48 ports negotiates 10M, 100M, 1G, 2.5G, 5G or 10G, and 10M and 100M run in full duplex only. Cat5e carries a port up to 5G; a 10G link needs Cat6 for runs up to 55 m or Cat6A for the full 100 m.
With C9350-NM-4C installed, four 100G/40G QSFP28 ports give the switch 400 Gbps of uplink. The slot also takes C9350-NM-2C, C9350-NM-8Y or C9350-NM-8M when 200G of fiber or eight Multigigabit copper uplinks is enough, and it ships empty.
Two Silicon One A100/L ASICs give the switch 1760 Gbps of switching capacity and 1309.44 Mpps of forwarding. The packet buffer totals 36 MB, with 18 MB on each ASIC.
The default PWR-C2-500WAC-I sits in the first of three bays, and supplies of different wattages can fill the other two in Combined or N+1 Redundant mode. In tests on an 850W supply at 115VAC, the switch drew 263.2 W with every port at full traffic and no uplink module, and 310.1 W with C9350-NM-4C installed.
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 into one 55V power pool. Neither cable type is shared with Catalyst 9300 switches.
One hardware model serves both management paths: Cisco Catalyst Center on premises or the Meraki dashboard in the cloud. There is no regional or management-specific hardware variant to choose.
Application Scenarios
On office floors where desktops and workstations connect at 2.5G, 5G or 10G, the switch links each desk at Multigigabit speed over the existing Cat6 or Cat6A horizontal cabling.
A wiring closet or small equipment room can bring local servers and other 10G copper devices onto the switch, with their traffic leaving the closet over a 100G QSFP28 uplink module.
Campus networks that keep lab, guest and staff traffic apart run the switch as an SD-Access edge for wired users whose devices draw no power from the network.

C9350-48TX and C9350-48HX share 48 10G Multigigabit ports, a 400G uplink slot and 1760 Gbps of switching, but the data-only model ships on a 500W supply with no PoE, while the UPOE+ model carries 90W per port with 1150W of PoE by default and 4320W on three 1600W supplies. Closets that must power access points, phones or cameras from the switch need C9350-48HX. Where every endpoint links at 1G, C9350-48T keeps the data-only design on 48 10M/100M/1G ports with 496 Gbps of switching and up to 200G of uplink. The license tier is not tied to the hardware: Essentials or Advantage comes from the 48-port subscription, and all stack members 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-4C, C9350-NM-2C, C9350-NM-8Y or C9350-NM-8M as its own line. The base switch ships with an empty uplink slot.
- Second power supply: Only the default PWR-C2-500WAC-I ships. Add PWR-C2-500WAC-I/2 or another /2 supply when the switch needs N+1 power redundancy without relying on StackPower+.
- 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. Each cord type must match the destination country.
- 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.
- 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.
