What Is the Cisco Catalyst C9300-48P-M?
The Cisco Catalyst C9300-48P-M is a 48-port PoE+ Layer 3 switch optimized for scalable enterprise access layers. It features 48x 1G PoE+ RJ45 ports and 4x 1G/10G SFP+ uplinks, with a 740W total PoE budget for powering devices like wireless APs, IP cameras, and VoIP phones. The “M” suffix denotes a modular power supply design, allowing organizations to upgrade or replace power modules for redundancy or higher capacity.
Key Technical Specifications
- Ports: 48x 1G PoE+ RJ45 ports (30W per port) + 4x 1G/10G SFP+ uplinks.
- Power Supplies: Supports modular PSUs (e.g., 715W AC or 1100W AC) for flexibility in PoE scaling.
- Stacking: StackWise-480 technology for up to 480 Gbps stacking bandwidth across 8 switches.
- Performance: 176 Gbps switching capacity and 130 Mpps forwarding rate.
- Software: Cisco IOS XE with DNA Essentials or Advantage (license-dependent), enabling automation and encrypted traffic analytics.
- Security: MACsec-128, Cisco TrustSec, and role-based access control (RBAC).
Primary Use Cases
- High-Density Wireless: Powers Cisco 9120/9130 APs in large office campuses or conference centers.
- Healthcare Networks: Supports connected medical devices and nurse call systems with PoE+ reliability.
- Retail Environments: Delivers power to POS terminals, digital signage, and security cameras.
- Modular Scalability: Ideal for organizations needing future-proof power upgrades without replacing entire switches.

Practical Deployment Notes
The C9300-48P-M’s modular power design is its standout feature, but it demands strategic planning. In a recent hotel deployment, upgrading to dual 1100W PSUs allowed the switch to power 40x IP phones and 25x APs simultaneously. However, initial setups often overlook PSU compatibility checks—always verify voltage requirements for global deployments. While the 10G uplinks suffice for most scenarios, pairing it with 40G core switches (e.g., C9300-24H) future-proofs bandwidth demands. If opting for DNA Essentials, budget for eventual upgrades to Advantage for full visibility into PoE utilization and threat analytics.
