FAQs

Q: Does the WS-C3850-12S-E support Power over Ethernet?
A: No, this model does not support PoE or PoE+. It is a fiber uplink switch with 12 SFP ports designed for aggregation and fiber-optic connectivity.

Q: What uplink modules are compatible with this switch?
A: The WS-C3850-12S-E supports the C3850-NM-4-1G (4 x 1G SFP) and C3850-NM-2-10G (2 x 1G + 2 x 10G SFP+) network modules. These are hot-swappable and provide flexible uplink expansion options.

Q: Can this switch be stacked with other Catalyst 3850 models?
A: Yes, but IP Services switches can only stack with other IP Services-licensed 3850 switches. It uses StackWise-480 technology to connect up to 9 switches with 480 Gbps total stack bandwidth.

Q: What routing protocols are supported with IP Services?
A: The IP Services license enables advanced Layer 3 features including OSPF, EIGRP, BGP, VRF-Lite, MPLS, multicast routing, advanced QoS, policy-based routing, and Cisco TrustSec security.

Q: Is a wireless controller license required for wireless management?
A: The switch includes integrated wireless controller functionality supporting up to 100 access points and 2,000 wireless clients per switch or stack, providing unified wired and wireless management on a single platform.
