Cisco WS-C3850-48UW-S | Catalyst 3850 48-Port Gigabit UPOE Switch, 800W, IP Base

Q: What is the difference between UPOE and PoE+?
A: UPOE (Universal Power over Ethernet) provides up to 60W per port compared to PoE+ which delivers up to 30W per port. This makes the WS-C3850-48UW-S ideal for powering high-wattage devices such as PTZ cameras, digital building systems, VDI thin clients, and advanced 802.11ac Wave 2 wireless access points that require more than the standard PoE+ can deliver.

Q: What uplink modules are compatible with this switch?
A: The WS-C3850-48UW-S has one network module slot that supports C3850-NM-4-1G (4x 1G SFP), C3850-NM-2-10G (4x 1G SFP or 2x 10G SFP+), and C3850-NM-4-10G (4x 10G SFP+) modules. Uplink modules are sold separately and provide flexible fiber or high-speed connectivity options.

Q: Does this switch include a wireless controller?
A: Yes, the WS-C3850-48UW-S includes an integrated wireless LAN controller that supports up to 50 access points and 2,000 wireless clients per switch or stack. It includes 5 access point licenses with the IP Base software and supports 802.11ac wireless standards, enabling unified wired and wireless management on a single platform.

Q: Can this switch be stacked with other Catalyst 3850 models?
A: Yes, the WS-C3850-48UW-S supports Cisco StackWise-480 technology, allowing you to stack up to 9 switches with 480 Gbps of stack bandwidth. It can be stacked with other Catalyst 3850 series models and supports StackPower for redundant power sharing across stack members.

Q: What is the total PoE budget available on this switch?
A: The WS-C3850-48UW-S includes a 1100W AC power supply and provides up to 800W of PoE budget for connected devices. This allows you to power multiple high-wattage UPOE devices simultaneously. A second 1100W power supply can be added for redundancy and increased PoE capacity.
