FAQs

Q: Does the WS-C3850-12S-S support Power over Ethernet (PoE)?
A: No, this model does not support PoE. It features 12 Gigabit SFP fiber ports optimized for uplink and aggregation connectivity without PoE capabilities.

Q: What network modules are compatible with this switch?
A: The WS-C3850-12S-S supports the C3850-NM-4-1G (4x 1G SFP) and C3850-NM-2-10G (2x 10G SFP+) network modules for flexible uplink expansion. Note that some modules have compatibility restrictions based on port configuration.

Q: Can this switch function as a wireless LAN controller?
A: Yes, with IP Base licensing, the switch includes embedded wireless controller functionality supporting up to 100 access points and 2000 wireless clients per switch or stack, providing converged wired and wireless management.

Q: What routing protocols are supported with IP Base?
A: IP Base licensing includes static routing, RIP, OSPF, EIGRP stub, PIM-lite, and IPv6 routing. For full Layer 3 routing capabilities including BGP and advanced features, an upgrade to IP Services license is available.

Q: How does StackWise-480 improve performance?
A: StackWise-480 technology allows up to nine Catalyst 3850 switches to operate as a single logical unit with 480 Gbps of stack bandwidth, providing high availability, simplified management, and seamless scalability for growing networks.
