C9300LM-48T-4Y-A Catalyst 9300LM 48-Port Data, Advantage

The -A on this 9300LM is the Network Advantage licence, which Cisco describes as adding advanced routing, segmentation, multicast, scale and security over Network Essentials. The C9300LM-48T-4Y-E is identical hardware at the base tier.

In the part number, LM marks the 9300LM line ("Catalyst 9300 mini" in the ordering guide), T means 48 data-only ports at 10/100/1000 Mbps with no PoE, and -4Y means four fixed SFP28 uplinks, rated at 25G in Cisco's data sheet.

Power: a PWR-C6-600WAC with fixed fans, per Cisco's install guide. The 9300LM uses its own PWR-C6 supplies; Cisco states that PWR-C1 units cannot be used.

Performance: 296 Gbps switching capacity, 616 Gbps when stacked, and 220.22 Mpps.

Stacking: up to 8 members over StackWise-320 at 320 Gbps with the optional C9300L-STACK-KIT2. Cisco ended sale of the earlier C9300L-STACK-KIT on November 3, 2025. 9300LM and 9300L switches stack together only at the same licence level, so this unit stacks with Advantage switches. It cannot stack with modular-uplink 9300 models, and StackPower is not supported.

Ordering note: for new switches from Cisco, a Cisco DNA or Catalyst subscription term licence of the same tier is required, per the ordering guide. The model is current in the ordering guide with no EoL bulletin.

Nearest sibling: the C9300LM-48U-4Y-A adds Cisco UPOE to all 48 ports, with a 790 W budget on a PWR-C6-1KWAC.
