Cisco C9300LM-24U-4Y-A | Catalyst 9300L Mini 24-Port Gigabit UPoE Switch, 420W, 4x 25G SFP28

Q: What is the difference between UPoE and standard PoE+?
A: UPoE (Universal PoE) provides up to 60W per port versus 30W for PoE+, enabling high-power devices like Wi-Fi 6 access points, building automation systems, and PTZ cameras without external injectors. With the optional 1KW power supply, all 24 ports can deliver full 60W simultaneously.

Q: Can this switch be stacked with other Catalyst 9300 models?
A: Yes, the C9300LM-24U-4Y-A supports StackWise-320 with up to 8 switches via the optional stacking kit. It can stack with other C9300L and C9300LM models running the same license tier (Network Advantage). It cannot stack with modular uplink C9300 or C9300X models.

Q: What are the 25G SFP28 uplinks used for?
A: The four 25G SFP28 uplinks provide high-speed connectivity to distribution or core switches, supporting future-proof bandwidth aggregation for dense Wi-Fi 6/6E deployments, 5G backhaul, or high-throughput applications. They support 1G, 10G, and 25G speeds with dual-rate optics.

Q: Does the Network Advantage license include DNA subscription?
A: The Network Advantage license is a perpetual network license included with this SKU. For advanced features like Cisco DNA Center automation, AI-driven analytics, and SD-Access, a separate Cisco DNA Advantage or Premier subscription is required.

Q: Is this switch suitable for industrial or outdoor environments?
A: No, the C9300LM is designed for indoor, temperature-controlled wiring closets and server rooms. For industrial or outdoor deployments, consider Cisco's IE (Industrial Ethernet) or ruggedized Catalyst models with extended temperature ranges.
