Description

The Catalyst 9300LM is a compact, stackable enterprise access switch from the Catalyst 9300 family, built for campus and branch access layers where rack depth is limited and PoE demand is high. At about 33 cm deep, it suits closets that need to power wireless access points, IP phones, cameras, thin clients and IoT devices over a single cable.

This model, the Network Essentials variant, provides 48 x 10/100/1000 Mbps ports with Cisco UPOE at up to 60W per port, plus four fixed 25G SFP28 uplinks for the distribution layer. A single 1000W AC power supply delivers 790W of PoE budget, and a second power supply can raise that to 1390W with a 600W AC unit, 1505W with a 715W DC unit or 1790W with a 1000W AC unit. Switching capacity is 296 Gbps standalone and 616 Gbps when stacked, with a forwarding rate of 220.22 Mpps. It carries 8 GB of DRAM and 16 GB of flash, and runs Cisco IOS XE.

It stacks with other Catalyst 9300L and 9300LM models at the same licence level using StackWise-320, and it ships with the Network Essentials licence tier.

FAQs

Q: Which licence does the C9300LM-48U-4Y-E use?
A: It uses the Network Essentials tier. A Cisco Catalyst or DNA subscription term licence at the matching Essentials tier is required on new deployments, and an upgrade to Network Advantage is available through C9300L-LIC=.

Q: How much PoE budget does it provide?
A: With the default 1000W AC power supply (PWR-C6-1KWAC) it provides 790W of PoE. A second power supply increases this to 1390W with a 600W AC unit, 1505W with a 715W DC unit or up to 1790W with a 1000W AC unit.

Q: Can it be stacked with other Catalyst 9300 switches?
A: It stacks only with other Catalyst 9300L and 9300LM models at the same licence level, using StackWise-320 and the optional C9300L-STACK-KIT2. It cannot stack with C9300 or C9300X modular uplink models, and StackPower is not supported.

Q: Can the uplinks be changed to a different speed?
A: No. The four 25G SFP28 uplinks are fixed and there is no modular uplink slot. Optics follow the Cisco transceiver compatibility matrix.

Q: Does it use the same power supplies as other Catalyst 9300 models?
A: No. The C9300LM models use different power supplies from the C9300, C9300X and C9300L, with the default being the PWR-C6-1KWAC.
