Cisco WS-C3850-24U-L | Catalyst 3850 24-Port Gigabit UPOE Switch, 800W

Q: What is the difference between UPOE and standard PoE+?
A: UPOE (Universal Power over Ethernet) delivers up to 60W per port, double the 30W maximum of PoE+ (802.3at). This enables support for high-power devices such as video collaboration endpoints, pan-tilt-zoom cameras, thin clients, and building automation systems that standard PoE cannot support.

Q: Which network modules are compatible with the WS-C3850-24U-L?
A: The switch supports C3850-NM-4-1G (4 x 1G SFP) and C3850-NM-2-10G (2 x 1G + 2 x 10G SFP+) network modules for flexible uplink options. The C3850-NM-4-10G and higher-speed modules are only supported on 48-port models. No module is included by default; it must be ordered separately.

Q: Can I upgrade from LAN Base to IP Base or IP Services?
A: Yes, Cisco Catalyst 3850 switches support transparent software license upgrades using the Right-to-Use (RTU) activation process via IOS CLI. Upgrading to IP Base enables full Layer 3 routing, wireless controller functionality for up to 100 access points, and support for 1,000 VLANs.

Q: How many switches can be stacked together?
A: Up to 9 switches can be stacked using StackWise-480 technology, delivering 480 Gbps of stacking bandwidth. The stack operates as a single logical unit with unified management, stateful switchover (SSO), and seamless failover for high availability.

Q: Does this switch include redundant power supply support?
A: Yes, the WS-C3850-24U-L supports dual redundant AC or DC power supplies and features StackPower technology, which allows up to four switches to share power resources in either power-sharing or redundant mode for enhanced resilience.
