WS-C3850-24XU-S provides Layer 3 enterprise access through 24 copper downlinks supporting 100Mbps, 1G, 2.5G, 5G, and 10G. Cisco UPOE supplies endpoint power alongside PoE and PoE+, accommodating compatible phones, wireless access points, and higher-draw devices. This Rack-Mount 1U member of the Catalyst 3850 family includes the IP Base feature set. Its empty uplink bay accepts separately selected network modules rather than providing fixed uplink ports. Supported choices include C3850-NM-4-1G for four 1G connections, C3850-NM-8-10G for eight 10G connections, and C3850-NM-2-40G for two 40G connections. The discontinued WS-C3850-24U-S offers a larger 800W default PoE allocation, while this configuration provides multigigabit endpoint connections rather than Gigabit-only downlinks.
WS-C3850-24XU-S price for new stock is $2,635.50, a 81% saving from the Cisco list price of $13,900.00. WS-C3850-24XU-S refurb price is $407.11. WS-C3850-24XU-S is in stock and available for next-day dispatch. (terms applied)

640 Gbps switching capacity supports the multigigabit interface configuration, while 500 Mpps forwarding applies to 80-byte packets. 580W of available PoE must be allocated across attached endpoints rather than treated as unrestricted power on every port. Static routing, RIPv1, RIPv2, RIPng, EIGRP Stub, OSPF for routed access, and PBR provide the included routing options; full BGPv4 and IS-ISv4 require IP Services. WS-C3850-24XU-S carries 4 GB of DRAM and 2 GB of flash for runtime operation and local software storage. The Cisco Catalyst 3850 Series supports 32000 MAC entries and 24000 total IPv4 entries covering ARP and learned routes. Cisco IOS XE provides CLI configuration and management integration with Cisco Prime Infrastructure. MSTP, PVRST+, and LACP support spanning-tree control and aggregated links. Three C3850-FAN-T1= fan modules cool the chassis, and the second power-supply bay ships empty rather than providing two installed supplies as standard.
WS-C3850-24XU-S can be ordered new sealed or certified refurbished; certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified, and configuration wiped to factory default. ORM's new sealed orders carry up to a 3-year extended warranty, certified refurbished orders carry up to 1 year, and both conditions include 30-day returns, terms apply; Cisco's Enhanced Limited Lifetime Warranty support ended October 31, 2025. Specify the condition, required accessories, and quantity on the PO. Enterprise and volume orders accept POs, government buyers receive Net-30 terms, and RMA with advance replacement is available across UK, EU, US, and MEA stock/RMA regions.

Deploy WS-C3850-24XU-S Catalyst 3850 24 mGig Port UPOE IP Base at the wiring closet of a global corporate campus to aggregate next-generation Wi-Fi 6 access points. Its 24 multigigabit UPOE ports deliver up to 60 W per port, powering Cisco Catalyst 9100 Series APs at full performance. The integrated IOS XE software and four 10 GbE SFP+ uplinks ensure seamless, scalable bandwidth, centralized policy enforcement, and single-pane orchestration via Cisco DNA Center. Benefit: future-proof wireless throughput, simplified PoE-powered deployments, and unified management that maximizes end-user experience and operational efficiency.
Integrate WS-C3850-24XU-S Catalyst 3850 24 mGig Port UPOE IP Base on the factory automation floor to power and connect robotic arms, intelligent sensors, and HD video inspection cameras. With a 480 W total PoE+ budget and 60 W per port, the switch eliminates separate power runs and reduces installation time. The Catalyst 3850’s deterministic QoS, segment routing, and embedded SD-Access fabric deliver reliable, low-latency traffic handling for real-time control. Benefit: streamlined cabling, enhanced device uptime, and secure, high-performance connectivity for Industry 4.0 operations.
Deploy WS-C3850-24XU-S Catalyst 3850 24 mGig Port UPOE IP Base in university or hospital campuses for centralized management of pan-tilt-zoom (PTZ) and 4K security cameras. The switch’s UPOE capability powers advanced cameras while its IP Base feature set—ACLs, segmentation, and TrustSec—isolates surveillance traffic. Embedded StackWise-480 technology provides resilience and up to 480 Gbps of stacking bandwidth for nonstop operation. Benefit: robust, high-power PoE delivery, hardened network segmentation, and uninterrupted video streaming that strengthen physical security and compliance.
When extending an existing stack, a LAN Base member cannot join an IP Base or IP Services stack. Select STACK-T1-50CM=, STACK-T1-1M=, or STACK-T1-3M= to match rack spacing; StackPower uses separate CAB-SPWR-30CM= or CAB-SPWR-150CM= cables. Confirm the member's active feature set and the required cable lengths before the PO.
When standardizing segmentation across multiple sites, IP Base paired with Cisco DNA Advantage allows only three virtual networks. That restriction belongs to the licensing combination rather than port density. Record the required virtual-network count and existing subscription entitlements, then confirm the intended segmentation design before specifying software on the PO.
When staging replacement hardware for an established management workflow, SSH and cryptographic SNMPv3 require a cryptographic software image. Confirm the intended image against the site's administrator-access requirements rather than relying on the hardware part number alone. Include image verification and configuration staging requirements in the purchasing specification before the PO.
Ongoing Cisco hardware support
Cisco service for this model ended October 31, 2025. C9300-24U-A is the migration replacement for buyers moving away from unsupported Catalyst 3850 hardware.
90W power for individual endpoints
Cisco UPOE limits individual powered ports to 60W. Adding another PWR-C1-1100WAC increases the aggregate power budget but does not raise the individual port output limit to 90W.
Full routing with the included license
IP Base does not enable BGPv4, IS-ISv4, full EIGRP, or full OSPF. These functions require IP Services rather than the included network feature set.

WS-C3850-24XU-S identifies a Catalyst 3850 switch: WS-C3850 is the switch family, 24 is the access-port count, XU denotes the multigigabit Cisco UPOE configuration, and S selects IP Base. The configuration includes an 1100W PWR-C1-1100WAC supply and a modular uplink bay rather than fixed uplinks.
WS-C3850-24XU-S supports Cisco IOS XE CLI management through console access, SSH, or Telnet, with SNMPv1, SNMPv2c, and SNMPv3 monitoring plus Cisco Prime Infrastructure or Cisco DNA Center integration. SSH and cryptographic SNMPv3 require the appropriate cryptographic software image; centralized features also depend on their software entitlements.
WS-C3850-24XU-S is discontinued: Cisco end of sale was October 30, 2020, and the last date of support was October 31, 2025. Cisco hardware service and vulnerability support have ended. C9300-24U-A is the migration replacement; purchasing the older unit requires planning for operation without ongoing Cisco support.
ORM Systems offers WS-C3850-24XU-S new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year. Both conditions include 30-day returns; terms apply. Cisco's original Enhanced Limited Lifetime Warranty no longer provides support: Cisco service and warranty support ended October 31, 2025.
Catalyst 3850 licensing included perpetual LAN Base, IP Base, and IP Services, with RTU upgrades; WS-C3850-24XU-S includes IP Base. Optional Cisco DNA Essentials and Cisco DNA Advantage used 3- or 5-year terms, while Cisco DNA Premier bundles had a 3-year minimum. Cisco ONE Software provided another suite-purchasing path. Subscription expiry permits continued base operation after deactivation and reload.
WS-C3850-24XU-S provides a shared 580W PoE budget with its shipped PWR-C1-1100WAC supply; a second PWR-C1-1100WAC increases available PoE to 1680W. Cisco UPOE can deliver 60W per port, but the default budget cannot power all 24 ports at 60W simultaneously. Size the supply configuration against combined endpoint requirements.
Catalyst 3850 multigigabit switches accept C3850-NM-4-1G, C3850-NM-2-10G, C3850-NM-4-10G, C3850-NM-8-10G, and C3850-NM-2-40G, providing 1G, 10G, and 40G uplink choices. C3850-NM-8-10G adds eight 10G connections, while C3850-NM-2-40G adds two 40G connections. WS-C3850-24XU-S ships without an uplink module; compatible optics must be selected and ordered separately for the intended links.
StackWise-480 connects nine Catalyst 3850 members with 480 Gbps stack bandwidth and one managed switching entity. Connection options are STACK-T1-50CM=, STACK-T1-1M=, and STACK-T1-3M=. LAN Base cannot mix with IP Base or IP Services; verify each member's active license and software image before adding hardware.
No, WS-C3850-24XU-S does not include BGPv4 under IP Base. Static routing, RIPv1, RIPv2, RIPng, EIGRP Stub, OSPF for routed access, and PBR are available. Full OSPF, EIGRP, BGPv4, and IS-ISv4 require IP Services. Buyers needing those functions must specify an appropriate license rather than treating them as included.
248.1W is the WS-C3850-24XU-S consumption at 100% IMIX traffic with C3850-NM-8-10G installed, measured at 115V AC and 60 Hz without PoE loading. That figure excludes power delivered to connected endpoints and is not a full PoE-loaded chassis maximum. Account separately for planned endpoint power when sizing electrical feeds.
WS-C3850-24U-S has an 800W single-supply PoE budget, compared with 580W for WS-C3850-24XU-S. Both models are discontinued legacy hardware. For like-for-like sparing, WS-C3850-24U-S provides the larger default endpoint allocation; WS-C3850-24XU-S requires tighter power budgeting or another PWR-C1-1100WAC when endpoint demand exceeds its standard allocation.
WS-C3850-24XU-E includes IP Services, whereas WS-C3850-24XU-S includes IP Base. IP Services enables full OSPF, EIGRP, BGPv4, and IS-ISv4 rather than the narrower routed-access feature set. Both models are discontinued; the E configuration addresses legacy advanced-routing requirements, while the S configuration covers IP Base routed-access requirements.
C9300-24U-A is the migration replacement for WS-C3850-24XU-S, whose Cisco support ended October 31, 2025. The Catalyst 9300 model belongs to the successor family rather than the original Catalyst 3850 generation. C9300-24U-A addresses migration purchases; WS-C3850-24XU-S addresses legacy spare purchases that do not require ongoing Cisco service.
