WS-C3850-24XUW-S provides 24 multigigabit copper access ports with Cisco UPOE in a managed Layer 3 access switch. Each downlink supports 100 Mbps, 1G, 2.5G, 5G and 10G, allowing endpoint connections above Gigabit speed without changing to fiber interfaces. The Cisco Catalyst 3850 uses a full-width 1U rack chassis and ships with the IP Base feature set. Its modular uplink architecture leaves the network module to be selected separately rather than supplying fixed fiber uplinks. The discontinued WS-C3850-24PW-S is the PoE+ counterpart for buyers maintaining lower-power endpoint configurations. This 24-port multigigabit UPOE switch combines powered access connections with routed-access functionality, but its discontinued status must be considered separately from its hardware capabilities.
WS-C3850-24XUW-S price for new stock is $6,744.15, a 62.6% saving from the Cisco list price of $18,010.00. WS-C3850-24XUW-S refurb price is $1,627.50. WS-C3850-24XUW-S is in stock and available for next-day dispatch. (terms applied)

640 Gbps switching capacity accommodates the multigigabit access connections and supported uplink configurations. 500 Mpps forwarding is specified with 80-byte packets, so that packet size matters when comparing performance figures. A shared 580W PoE budget supplies connected endpoints with the standard power configuration; the per-port UPOE ceiling does not mean every port can simultaneously receive maximum power. Static routing, RIPv1, RIPv2, RIPng, EIGRP Stub, OSPF for routed access and PBR are available under IP Base; full OSPF, BGPv4 and IS-ISv4 require IP Services. WS-C3850-24XUW-S carries 4 GB DRAM and 2 GB flash for system operation and software storage. The Catalyst 3850 supports 32000 MAC entries and 24000 IPv4 entries covering ARP plus learned routes. The 248.1W consumption figure uses C3850-NM-8-10G at full traffic with no PoE load; endpoint power is additional.
ORM Systems supplies WS-C3850-24XUW-S in new sealed and certified refurbished condition; new orders include up to a 3-year extended warranty, refurbished orders include up to 1 year, and returns are 30 days in every condition, with terms applying. Certified refurbished units are inspected and bench-tested for power-on, POST, rated-speed port links and clean boot; PoE output is verified under load on every powered port, firmware is verified, and configuration is wiped to factory default. Specify condition, quantity and required accessory PIDs on the purchase order for this switch.

A university deploys WS-C3850-24XUW-S Catalyst 3850 switches with IP Base and 5 AP licenses to power and manage Wi-Fi 6 access points over 24 multigigabit uPoE ports. Outcome: 35% boost in wireless performance, seamless high-density coverage for 500+ concurrent users, and reduced PoE infrastructure costs.
In a corporate headquarters, network architects consolidate IP cameras, VoIP phones and environmental sensors onto WS-C3850-24XUW-S switches, leveraging 24 uPoE ports and IP Base advanced routing. Outcome: centralized power delivery, 40% less cabling, and guaranteed 24/7 uptime for critical security and voice services.
A retail chain implements WS-C3850-24XUW-S Catalyst 3850 switches in branch locations using StackWise–480 to form a unified switch fabric with IP Base routing and 5 AP licenses. Outcome: sub-50 ms failover, simplified remote management, and scalable 480 Gbps backbone for future expansion.
When replacing an access switch serving high-draw endpoints, distinguish individual port capability from aggregate demand. Twenty-four endpoints requesting 60W represent 1440W of endpoint power. Full UPOE operation across those ports requires two PWR-C1-1100WAC supplies. Specify the endpoint allocation and second PWR-C1-1100WAC on the purchase order.
When adding a member to an installed stack, cable reach becomes a separate purchasing decision from switch selection. STACK-T1-50CM=, STACK-T1-1M= and STACK-T1-3M= provide different connection lengths. Measure the actual rack layout, including the return connection, and specify the required stacking cable PIDs before issuing the purchase order.
When reproducing an existing converged-access configuration in a staging environment, the bundle's five access point licenses require attention to software compatibility. Converged Access is unsupported beyond Cisco IOS XE Denali 16.3.x. Record the intended software release and access point compatibility requirements before specifying the unit for the lab purchase order.
Active Cisco hardware service coverage
Cisco service ended October 31, 2025. C9300-24U-A is the current replacement, but its 24 UPOE access ports are Gigabit rather than multigigabit.
Integrated wireless control beyond Denali
Converged Access is unsupported beyond Cisco IOS XE Denali 16.3.x. The bundled access point licenses do not enable that functionality in later software releases.
BGP routing with the supplied license
The supplied IP Base feature set excludes BGPv4. Advanced routing requirements need a different license entitlement rather than relying on the switch's hardware route capacity alone.

WS-C3850-24XUW-S identifies a Catalyst 3850 bundle: WS-C3850 names the family, 24 identifies the access-port count, X identifies multigigabit connections, U identifies UPOE, W identifies the five-access-point-license bundle, and S identifies IP Base. The complete PID matters when an order must include the wireless license bundle rather than the unbundled hardware variant.
WS-C3850-24XUW-S supports a web UI, Cisco IOS CLI through a local console or remote Telnet, SSH with the appropriate cryptographic image, Cisco Network Assistant, and Cisco Prime Infrastructure. Select the intended management method during staging and confirm the installed software image supports the required secure remote-access configuration.
Yes, WS-C3850-24XUW-S is discontinued, and Cisco support ended October 31, 2025. End of sale occurred October 30, 2020. C9300-24U-A is the replacement PID. Purchasing remaining hardware does not restart Cisco service eligibility or extend the expired support milestones for this model.
ORM offers new sealed and certified refurbished WS-C3850-24XUW-S, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Returns are 30 days in every condition; terms apply. Cisco's original Enhanced Limited Lifetime Warranty ended with Cisco support on October 31, 2025.
No, WS-C3850-24XUW-S operates with its permanent IP Base entitlement without a Cisco DNA subscription. Optional Cisco DNA Essentials and Cisco DNA Advantage add-ons have three-year minimum terms, with five-year terms also offered. After an add-on expires, deactivating it and reloading leaves the base license capabilities available.
WS-C3850-24XUW-S provides a shared 580W PoE budget with one PWR-C1-1100WAC supply, increasing to 1680W with a second PWR-C1-1100WAC. Cisco UPOE permits 60W per port, but the single-supply budget cannot provide that maximum simultaneously on all access ports. Size the supply configuration against actual endpoint demand.
The Catalyst 3850 multigigabit model accepts C3850-NM-4-1G, C3850-NM-2-10G, C3850-NM-4-10G, C3850-NM-8-10G and C3850-NM-2-40G. These provide module-dependent Gigabit, 10G or 40G connections. The default chassis configuration does not include a network module, so specify the required module PID and compatible optics separately rather than expecting fixed fiber uplinks.
StackWise-480 stacks eight Catalyst 3850 multigigabit members, subject to the 32-ASIC ceiling; each multigigabit member contributes four ASICs. Mixed stacks require a silicon-count check and matching feature sets. STACK-T1-50CM=, STACK-T1-1M= and STACK-T1-3M= are the stacking cable options to specify according to the rack layout and return-path distance.
No, the Catalyst 3850 bundle's five access point licenses do not enable Converged Access beyond Cisco IOS XE Denali 16.3.x. Later releases do not support that function. Treat the wireless entitlement and the installed software release as separate compatibility checks when reproducing an older converged-access configuration.
WS-C3850-24XUW-S supplies Cisco UPOE, while WS-C3850-24PW-S supplies PoE+; both are IP Base bundles with five access point licenses. Both models are discontinued. The UPOE model suits legacy installations needing higher per-port endpoint power, while the PoE+ model suits existing installations whose endpoint requirements remain within PoE+ limits.
WS-C3850-24XUW-S carries IP Base, while WS-C3850-24XU-E carries IP Services. IP Base includes OSPF for routed access; IP Services adds full OSPF, EIGRP, BGPv4 and IS-ISv4. Both models are discontinued. The former suits legacy routed-access requirements, while the latter suits legacy configurations requiring the broader routing feature set.
WS-C3850-24XUW-S provides multigigabit UPOE downlinks, while C9300-24U-A provides Gigabit UPOE downlinks and is the current replacement. The older model's Cisco support has ended. The older hardware suits maintaining an existing multigigabit configuration; the replacement suits refresh orders whose endpoint connections do not require multigigabit access speeds.
