C9300LM-24U-4Y-A Description

  Cisco Catalyst C9300LM-24U-4Y-A is a 1 RU, stackable access switch designed for space-constrained deployments. It offers 24 Cisco UPOE ports (1 Gbps/100 Mbps/10 Mbps) and four fixed 25 Gbps SFP28 uplinks. A default 600 W AC power supply delivers 420 W of PoE, with an optional 1 kW AC PSU upgradeable to full 24 × 60 W UPOE (1,440 W). Running Cisco IOS XE with the Network Advantage license, it provides 248 Gbps switching capacity (568 Gbps in an 8-member StackWise-320 stack) and 184.51 Mpps forwarding (422.59 Mpps stacked). Advanced security features (MACsec, Encrypted Traffic Analytics), robust QoS, and real-time telemetry make it ideal for dense IoT/edge and compact wiring closets.
