Cisco C9300LM-48U-4Y-E | Catalyst 9300L Mini 48-Port Gigabit UPOE Switch, 790W, 4x 25G SFP28

Q: What is the difference between Network Essentials and Network Advantage licensing?
A: Network Essentials provides base Layer 2 and Layer 3 switching capabilities including routing protocols like OSPF, EIGRP, and BGP. Network Advantage adds advanced features such as SD-Access readiness, Cisco TrustSec, LISP, VXLAN, and enhanced security capabilities. Both licenses are perpetual and include Cisco IOS XE software.

Q: What is the maximum PoE power budget and how many ports support UPOE?
A: The C9300LM-48U-4Y-E comes with a default 1000W power supply (PWR-C6-1KWAC) providing 790W PoE budget. All 48 ports support Cisco UPOE delivering up to 60W per port for high-power devices like Wi-Fi 6 access points, PTZ cameras, and IoT endpoints. The switch has 2 FRU power supply slots for redundancy or additional PoE capacity.

Q: Can this switch be stacked with other Catalyst 9300 models?
A: Yes, but only with other Catalyst 9300L or 9300LM fixed uplink models. It cannot stack with modular uplink models (C9300/C9300X SKUs) or older switches like the Catalyst 3850/3650 Series. Stacking requires the optional StackWise-320 kit and supports up to 8 switches with 320 Gbps stacking bandwidth.

Q: What uplink connectivity does this model support?
A: The C9300LM-48U-4Y-E has four fixed 25G SFP28 uplink ports, providing high-speed connectivity for aggregation or core switches. These fixed uplinks cannot be changed or expanded with network modules, unlike the modular C9300 Series switches.

Q: Is this switch suitable for supporting Wi-Fi 6 access points?
A: Yes, the Catalyst 9300L Mini is specifically optimized for high-density Wi-Fi 6 and 802.11ac Wave 2 deployments. With UPOE delivering 60W per port and UADP 2.0 ASIC architecture, it efficiently handles the power and bandwidth requirements of multiple Wi-Fi 6 access points with features like Perpetual PoE and Fast PoE for uninterrupted operation.
