Cisco C9300LM-48UX-4Y-E | Catalyst 9300L 48-Port UPOE Switch, 790W, 8x 10G mGig, 4x 25G SFP28

Q: What is the difference between the C9300LM-48UX-4Y-E and C9300LM-48UX-4Y-A?
A: The E suffix denotes Network Essentials license, while the A suffix denotes Network Advantage license. Network Advantage includes additional advanced routing features, enhanced security, and more comprehensive Layer 3 capabilities compared to Network Essentials. Both require a mandatory 3, 5, or 7 year Cisco DNA subscription.

Q: How many watts of PoE power does this switch provide?
A: With the default PWR-C6-1KWAC 1000W AC power supply, the switch delivers 790W PoE budget for Cisco UPOE (60W per port) and PoE+ (30W per port) across all 48 ports. For higher power requirements, an optional secondary power supply can be added to increase total PoE capacity.

Q: Can this switch be stacked with other Catalyst 9300 models?
A: The C9300LM series can be stacked with other C9300L and C9300LM models using the optional StackWise-320 kit. Up to 8 switches can form a single logical unit with 320 Gbps stacking bandwidth. It cannot be stacked with modular uplink C9300 or C9300X models, or older Catalyst 3850/3650 switches.

Q: What is the benefit of the Multigigabit ports on this switch?
A: The 8 Multigigabit ports auto-negotiate at 100M, 1G, 2.5G, 5G, or 10G speeds over standard Cat5e/Cat6 cabling, ideal for connecting high-performance wireless access points like Wi-Fi 6 and Wi-Fi 6E models that require more than 1G backhaul. This eliminates the need for fiber runs to APs while delivering full UPOE power.

Q: Does this switch support Perpetual PoE and Fast PoE?
A: Yes, the Catalyst 9300LM supports both Perpetual PoE (maintains PoE power during switch reload for uninterrupted IoT device operation) and Fast PoE (delivers power to endpoints before the OS fully loads, speeding up device startup after power restoration). These features are critical for mission-critical IoT deployments.
