C9300LM-48U-4Y-E Catalyst 9300LM 48-Port UPOE, Essentials

The C9300LM-48U-4Y-E is a 9300LM, which Cisco's ordering guide calls "Catalyst 9300 mini". It has 48 Cisco UPOE ports at 10/100/1000 Mbps and four fixed SFP28 uplinks (-4Y), rated at 25G in Cisco's data sheet and install guide. The -E licence is Network Essentials, Cisco's base tier for Layer 2 and Layer 3 switching, automation, visibility and security. The C9300LM-48U-4Y-A is the same hardware with Network Advantage.

Power: the 9300LM takes PWR-C6 supplies only; Cisco states PWR-C1 units cannot be used. The default PWR-C6-1KWAC gives a 790 W PoE budget. A second 600 W AC supply raises it to 1390 W, and a second 1000 W AC supply to 1790 W.

Switching capacity is 296 Gbps (616 Gbps stacked), with a forwarding rate of 220.22 Mpps.

Stacking: StackWise-320 at 320 Gbps, up to 8 members, with the optional C9300L-STACK-KIT2. The 9300LM stacks with 9300L and other 9300LM switches only at the same licence level, so this unit belongs in an Essentials stack. It does not stack with modular-uplink 9300 models and has no StackPower.

New switches ordered from Cisco need a Cisco DNA or Catalyst subscription term licence at the same tier, per the ordering guide. The model is in the current ordering guide with no EoL bulletin.

Nearest sibling: the C9300LM-48UX-4Y makes 8 of the 48 UPOE ports Multigigabit (up to 10G) and raises switching capacity to 440 Gbps, on the same power supplies.
