Cisco Catalyst C9350-48HX 48-Port 10G Multi-Gigabit Switch with 90W UPOE+

The Cisco Catalyst C9350-48HX redefines access-layer switching for high-density, power-hungry environments. Unlike standard gigabit switches, this model pairs 48 multi-gigabit ports with 90W Universal Power over Ethernet Plus (UPOE+), delivering both data speeds up to 10 Gbps and enough power for next-generation Wi-Fi 6/6E access points, digital signage, and PoE-powered lighting—all in a compact 1RU form factor. Built on the Catalyst 9300 Series architecture, it brings enterprise-grade security, advanced stacking, and software-defined networking to the edge.

Highlights

• 48 x 10G Multi-Gigabit ports (100M/1G/2.5G/5G/10G) with UPOE+ up to 90W per port
• 640 Gbps switching capacity and 476.19 Mpps forwarding rate for demanding workloads
• StackWise-1T technology with up to 1 TBps stacking bandwidth for simplified management
• Modular uplink support for flexible connectivity options (uplink module sold separately)
• Advanced security: MACsec, TrustSec, SD-Access, and Encrypted Traffic Analytics (ETA)
• Redundant, modular power supplies and fans for high availability
• Layer 2 and Layer 3 capabilities with support for 4094 VLANs and jumbo frames up to 9198 bytes
• Powerful 2.4 GHz quad-core x86 processor with 8 GB DRAM and 16 GB flash

In daily use

Deploying the C9350-48HX means eliminating separate power injectors and midspans. Each port can supply up to 90W, enough to run the most power-hungry endpoints directly from the switch. The multi-gigabit ports automatically negotiate the best speed for existing cabling—Cat5e supports up to 5 Gbps, while Cat6a unlocks full 10 Gbps—so you can upgrade devices without rewiring. Stack up to eight switches for a single logical unit, and manage the entire stack through a familiar CLI, web interface, or modern APIs like NETCONF and RESTCONF. The switch’s hardware acceleration for encryption and analytics keeps traffic secure without sacrificing performance.
