Cisco WS-C3850-48U-L | Catalyst 3850 48-Port Gigabit UPOE Switch, 800W, LAN Base

Q: What is the difference between UPOE and PoE+?
A: UPOE (Universal Power over Ethernet) delivers up to 60W per port, double the power of PoE+ (30W). This enables the WS-C3850-48U-L to power high-performance devices such as PTZ cameras, video conferencing endpoints, building automation systems, and 802.11ac Wave 2 access points that require more than 30W.

Q: Can I stack the WS-C3850-48U-L with other Catalyst 3850 models?
A: The WS-C3850-48U-L with LAN Base license can only stack with other Catalyst 3850 Series switches running the LAN Base feature set. It cannot stack with IP Base or IP Services models. Stacking requires separate StackWise-480 cables (not included) and supports up to 9 switches with 480 Gbps of stack bandwidth.

Q: What network modules are compatible with this switch?
A: The WS-C3850-48U-L supports the C3850-NM-4-1G (4x 1G SFP), C3850-NM-2-10G (4x 1G SFP / 2x 10G SFP+), and C3850-NM-4-10G (4x 10G SFP+) network modules. These are sold separately and install in the single modular slot to provide uplink flexibility.

Q: Does this switch support wireless controller functionality?
A: Yes, the Catalyst 3850 Series includes integrated wireless controller functionality and can support up to 100 access points and 2,000 wireless clients per switch or stack. This enables converged wired and wireless management from a single platform using Cisco IOS XE software.

Q: What is the PoE budget and can I use a second power supply?
A: The switch ships with one 1100W AC power supply providing 800W of UPOE budget. A second power supply can be installed for redundancy or to increase available PoE power. Optional power supply models include PWR-C1-350WAC, PWR-C1-715WAC, PWR-C1-1100WAC (AC) and PWR-C1-440WDC (DC).
