C9300LM-24U-4Y-E Description
Cisco Catalyst C9300LM-24U-4Y-E (“LM” mini form) is a 1 RU, stackable access switch featuring 24 Cisco UPOE ports (1 Gbps/100 Mbps/10 Mbps) and four fixed 25 Gbps SFP28 uplink ports. Its 600 W AC power supply supports up to 420 W of PoE budget (default) and can be upgraded to a 1 kW AC PSU for full 24-port UPOE (1,440 W) support. Built on Cisco IOS XE, it delivers 248 Gbps switching capacity (568 Gbps with stacking) and 184.51 Mpps forwarding (422.59 Mpps with stacking). With advanced security (MACsec, Encrypted Traffic Analytics), robust QoS, and a small footprint, it’s ideal for dense IoT/edge deployments and small-form-factor closets.

Key Features
Cisco UPOE (60 W per Port)
Extends PoE to power high-draw endpoints (e.g., 802.11ax APs, PTZ cameras) without extra injectors.
4×25 Gb Fixed SFP28 Uplinks
Future-proof uplinks for high-bandwidth aggregation, ideal for 5G cell-site backhaul or dense Wi-Fi 6.
StackWise-320 Integration
Simplifies management by creating a single logical switch of up to eight members with 568 Gbps stack bandwidth.
Cisco IOS XE with Advanced Security
Includes MACsec encryption, Encrypted Traffic Analytics (ETA), Secure Boot, and segmentation for edge protection.
Robust QoS and Telemetry
Wire-speed QoS classification/policing and real-time telemetry (Cisco Telemetry) ensure SLA-grade performance.
Flexible PoE Power Options
Default 600 W PSU (420 W PoE) for low-power deployments, upgradeable to 1 kW for full 24×60 W UPOE support.
Application Scenarios
Fits in limited-space IDF/MDF closets to power and connect IP phones, cameras, and APs via UPOE.
Enables high-performance access with 25 Gb uplinks for converged campus edge in tight racks.
Provides UPOE to sensors, badge readers, or environmental monitors in manufacturing or hospital closets.
