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.
