Key Features
Dual Silicon One ASIC Architecture
The switch utilizes two Cisco Silicon One A100/L ASICs to deliver 1.3 Tbps of throughput per ASIC. This architecture provides a unified high-performance forwarding plane with deep buffers and flexible tables, ensuring consistent wire-speed performance for data-heavy applications.
Universal 90W UPOE+ Power
The C9350-48HX supports IEEE 802.3bt Type 4 UPOE+ technology, delivering up to 90W of power on all 48 ports simultaneously. This high-density power capability eliminates the need for electrical upgrades when deploying power-hungry devices like pan-tilt-zoom cameras, daisy-chained LED lighting, and high-performance thin clients.
Industry-Leading StackWise-1.6T
Featuring the new StackWise-1.6T technology, the switch offers 1.6 Tbps of aggregated stacking bandwidth. This allows up to eight switches to be managed as a single logical unit with distributed forwarding, scaling up to 384 Multigigabit ports without creating bandwidth bottlenecks between stack members.
400G-Ready Modular Uplinks
The platform supports high-speed modular uplinks, including the C9350-NM-4C module, which provides up to 400 Gbps of total uplink bandwidth (4x 100G). This flexibility supports seamless migration from 40G to 100G core connections as network traffic demands increase.
Advanced Hardware Security
The C9350-48HX is hardware-ready for advanced security features, including line-rate MACsec AES-GCM-256 encryption and high-scale IPsec up to 100G. It also supports Cisco Hypershield for distributed threat mitigation and is ready for post-quantum cryptography (PQC) algorithms.
Enhanced Application Hosting
With an x86-based multicore CPU, 16 GB of DDR5 memory, and support for local SSD storage, the switch can host containerized third-party applications. This enables edge computing capabilities, such as running Cisco ThousandEyes agents for direct visibility into network performance and user experience.
Applications Scenarios
Wi-Fi 7 and 6E High-Speed Backhaul
As organizations upgrade to Wi-Fi 6E and Wi-Fi 7, access points require Multigigabit backhaul (2.5G/5G) and high power (often >30W). The C9350-48HX provides the necessary 10G speeds and 90W UPOE+ to ensure these APs operate at full capacity without throughput throttling or power starvation.
High-Density Smart Buildings
In modern smart buildings, the network must power and connect a diverse range of IoT devices, from lighting and HVAC sensors to IP security systems. The C9350-48HX acts as a central power hub, offering a massive PoE budget (up to 4320W with dual power supplies) to drive these endpoints efficiently over a single Ethernet cable.
Data-Intensive Creative Workflows
For media studios, architectural firms, and engineering environments, transferring massive files is a daily necessity. The 10G copper ports on the C9350-48HX allow workstations to connect at 10 Gbps, significantly reducing file transfer times to local servers or the cloud compared to standard Gigabit switches.
