WS-C3850-24UW-S combines 24 Gigabit Ethernet copper access ports with Cisco UPOE and a five-access-point-license bundle for converged wired and wireless access. This managed Layer 3 model belongs to the Cisco Catalyst 3850 Series and ships with IP Base in a rack-mount 1U chassis. Uplinks are modular rather than built in: the base configuration has an empty bay for C3850-NM-4-1G or C3850-NM-2-10G. The configuration serves enterprise access networks connecting IP phones, access points and other powered endpoints. The discontinued WS-C3850-24PW-S bundle supplies PoE+ instead of UPOE, distinguishing lower per-port power requirements from this model's higher-power endpoint role. Three modular C3850-FAN-T1= fans provide active cooling; this is not a fanless enclosure.
WS-C3850-24UW-S price for new stock is $7,111.65, a 30.5% saving from the Cisco list price of $10,228.00. WS-C3850-24UW-S refurb price is $2,793.00. WS-C3850-24UW-S is in stock and available for free next-day delivery. (terms applied)

92 Gbps switching capacity defines the standalone switching ceiling for traffic between access interfaces and the selected uplinks. 800W of shared PoE capacity allocates endpoint power across the chassis; installing a second PWR-C1-1100WAC raises the available budget to 1900W. Static routing, RIPv1, RIPv2, RIPng, EIGRP Stub, OSPF for routed access and PBR are available under IP Base. Full OSPF, EIGRP, BGPv4 and IS-ISv4 require IP Services rather than the shipped entitlement. WS-C3850-24UW-S uses 4 GB of DRAM and 2 GB of flash for its Cisco IOS XE software environment. The Cisco Catalyst 3850 forwarding design uses the UADP ASIC, while its IPv4 capacity totals 24000 entries across ARP and learned routes. Administrators can use the web UI, console CLI, SSH, Telnet, Cisco Network Assistant, Cisco Prime Infrastructure and SNMP. SSH and SNMPv3 require a cryptographic software image, so image selection matters when specifying remote administration.
ORM Systems offers WS-C3850-24UW-S new sealed or certified refurbished: new units carry up to a 3-year extended warranty, refurbished units up to 1 year, and every condition has 30-day returns; terms apply. Refurbished units are inspected and bench-tested for power-on, POST, every port linking at rated speed, a clean boot and loaded PoE output on every powered port; firmware is verified and configurations wiped to factory default. Specify quantity, condition and accessories on the PO; Cisco's Enhanced Limited Lifetime Warranty ended with support on October 31, 2025. Enterprise and volume procurement supports PO acceptance, Net-30 for government and RMA with advance replacement, with regional stock and RMA in UK, EU, US and MEA.

In a corporate campus supporting a hybrid workforce, the Cisco Catalyst 3850 24-Port UPOE (WS-C3850-24UW-S) with 5 AP licenses and IP Base delivers unified wired/wireless services. It powers up to 24 high-performance APs, streamlines provisioning via Cisco DNA, and maintains consistent campus coverage. Outcome: 30% faster Wi-Fi onboarding, single-pane management, and predictable service levels across 500+ users.
In smart buildings, the WS-C3850-24UW-S supplies 60W UPOE per port to drive IP cameras, environmental sensors, digital signage and badge readers from one chassis. With IP Base routing and 5 AP licenses, facility teams gain centralized visibility, automated energy monitoring and PoE budgeting. Outcome: 25% reduction in rack-space devices, streamlined maintenance, and 24/7 operational assurance.
For retail branches requiring POS terminals, VoIP phones and guest Wi-Fi, the Catalyst 3850 (WS-C3850-24UW-S) enables per-port UPOE, advanced QoS and dynamic VLAN segmentation via IP Base. The included 5 AP licenses accelerate wireless rollout while enforcing AES encryption and NAC policies. Outcome: 40% faster store deployments, PCI-compliant transactions, and elevated customer experience.
When adding a member to an existing access stack, match the software feature set across all members before procurement. StackWise-480 provides 480 Gbps of stack bandwidth, with STACK-T1-50CM=, STACK-T1-1M= and STACK-T1-3M= cable options. Specify the member's license level, installed software and cable length on the PO.
When standardizing segmentation across existing sites, IP Base with Cisco DNA Advantage limits the Catalyst 3850 to 3 virtual networks. IP Services removes that particular restriction. Define the required virtual-network count, base-license entitlement and add-on package before specifying the order; a subscription alone does not provide unrestricted segmentation capacity.
When preparing branch shipments for rooms that may be unheated, distinguish operating conditions from startup requirements. The Catalyst 3850 requires a minimum cold-start ambient temperature of 0°C. Storage and transport conditions must not substitute for boot conditions. Check the startup environment, staging location and local power availability before releasing the hardware PO.
Active Cisco service coverage
WS-C3850-24UW-S passed its last support date on October 31, 2025. C9300-24U-A is its replacement for generation-refresh procurement rather than continued investment in discontinued hardware.
Four simultaneous 10G uplink interfaces
C3850-NM-2-10G provides two 10G interfaces on this model. C3850-NM-4-10G is incompatible with the 24-port Gigabit hardware, so the uplink bay cannot meet a four-interface 10G requirement.
Full BGPv4 routing under IP Base
IP Base excludes BGPv4, IS-ISv4 and full EIGRP; those features require IP Services. WS-C3850-24UW-S must not be specified for those protocols at its shipped license level.
Multigigabit copper endpoint connections
WS-C3850-24UW-S provides a 1G maximum copper access speed. Its optional 10G uplink capability does not increase the speed of fixed downlinks or provide 2.5G or 5G endpoint connections.

WS-C3850-24UW-S identifies a Catalyst 3850 bundle: WS-C3850 denotes the series, 24 the port count, U UPOE, W the five-access-point-license bundle, and S IP Base. The part number contains no fixed-uplink speed code. Uplink connectivity requires a separate selection rather than assuming that uplink ports ship installed.
WS-C3850-24UW-S is managed through the web UI, CLI over RJ-45 or USB console, SSH or Telnet, Cisco Network Assistant, Cisco Prime Infrastructure and SNMP. Console access handles initial setup. SSH and SNMPv3 require a cryptographic software image. Cisco DNA Center integration requires the appropriate add-on entitlement and network configuration.
WS-C3850-24UW-S is discontinued: end of sale was October 30, 2020, and Cisco support ended October 31, 2025. Software maintenance ended October 30, 2021, while vulnerability remedies ended October 31, 2025. C9300-24U-A replaces the bundle. Ordering remaining inventory does not extend Cisco's service or security-remediation deadlines.
ORM Systems offers WS-C3850-24UW-S new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Both conditions have 30-day returns; terms apply. Cisco's original Enhanced Limited Lifetime Warranty no longer provides service: Cisco support ended October 31, 2025.
WS-C3850-24UW-S includes perpetual IP Base; optional Cisco DNA Essentials, Cisco DNA Advantage and Cisco DNA Premier subscriptions start at three years. Cisco ONE software suites provided another purchasing route. Subscription expiration preserves the base license, but continued add-on use requires renewal. Confirm software entitlement and Smart Account assignment separately from hardware condition.
No, WS-C3850-24UW-S cannot supply 60W to all 24 ports with its shipped PWR-C1-1100WAC. The 800W shared budget must be allocated against endpoint demand. Full-port UPOE operation requires adding PWR-C1-715WAC. Two PWR-C1-1100WAC supplies provide a 1900W budget. Specify the supply configuration against actual endpoint load rather than port count alone.
WS-C3850-24UW-S accepts C3850-NM-4-1G for four 1G uplinks or C3850-NM-2-10G for two 10G uplinks with two additional 1G ports. Neither C3850-NM-4-1G nor C3850-NM-2-10G ships in the base configuration. Order compatible transceivers separately; C3850-NM-4-10G, C3850-NM-8-10G and C3850-NM-2-40G are incompatible with this 24-port Gigabit hardware.
StackWise-480 stacks nine Catalyst 3850 members with 480 Gbps of stack bandwidth. WS-C3850-24UW-S must join members using the same software feature set rather than mixing IP Base with LAN Base or IP Services. Cable options are STACK-T1-50CM=, STACK-T1-1M= and STACK-T1-3M=. StackPower separately uses CAB-SPWR-30CM= or CAB-SPWR-150CM=.
WS-C3850-24UW-S supports Static, RIPv1, RIPv2, RIPng, EIGRP Stub, OSPF for routed access and PBR with IP Base. Full OSPF, EIGRP, BGPv4 and IS-ISv4 require IP Services. The 24000-entry IPv4 total includes ARP and learned routes; that hardware total does not grant unrestricted routing-protocol capability under the base entitlement.
No, WS-C3850-24UW-S ships with one PWR-C1-1100WAC and an empty second internal power bay. Redundancy is optional rather than standard. A second PWR-C1-1100WAC also changes available endpoint power. StackPower offers separate group power sharing through CAB-SPWR-30CM= or CAB-SPWR-150CM=. Specify the intended redundancy mode when listing supplies on the PO.
WS-C3850-24UW-S provides Cisco UPOE where discontinued WS-C3850-24PW-S provides PoE+; both are 24-port IP Base bundles with five access point licenses. UPOE addresses endpoints requiring higher per-port power, while the PoE+ bundle addresses lower-power requirements. Both models are legacy inventory choices rather than current Cisco hardware offerings.
WS-C3850-24U-E carries IP Services, where WS-C3850-24UW-S ships with IP Base. IP Services adds full OSPF, EIGRP, BGPv4 and IS-ISv4 beyond IP Base's routed-access features. Both models are discontinued; the IP Base bundle suits licensed routed-access sparing, while IP Services fits legacy deployments requiring those advanced routing protocols.
C9300-24U-A is the replacement generation for WS-C3850-24UW-S, whose Cisco support ended October 31, 2025. The replacement retains 24-port UPOE access but uses Network Advantage instead of IP Base. The discontinued 3850 bundle addresses like-for-like legacy sparing; the 9300 model addresses procurement for a generation refresh.
