FAQs

Q: What network modules are compatible with the WS-C3850-48W-S?
A: The WS-C3850-48W-S 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+) modules. Network modules are sold separately and are hot-swappable.

Q: Does the WS-C3850-48W-S support Layer 3 routing?
A: Yes, the IP Base feature set included with this model provides entry-level Layer 3 routing capabilities including static routing, RIP, OSPF, EIGRP, and policy-based routing. For advanced features like VRF-Lite and multicast routing, an IP Services license upgrade is required.

Q: How many wireless access points can this switch manage?
A: The WS-C3850-48W-S includes an integrated wireless controller that can manage up to 100 access points and 2000 wireless clients per switch or stack. It ships with 5 access point licenses included; additional licenses can be purchased separately.

Q: Can the WS-C3850-48W-S be stacked with other Catalyst 3850 models?
A: Yes, it supports StackWise-480 technology allowing stacking of up to 9 Catalyst 3850 switches with 480 Gbps of stack throughput. Stack members must run the same IOS feature set. StackWise cables are sold separately.

Q: What is the total PoE power budget available on this switch?
A: The WS-C3850-48W-S provides 435W of PoE+ power budget with the included 1100W AC power supply, delivering up to 30W per port (IEEE 802.3at). A second redundant power supply can be added for increased PoE capacity and redundancy.
