WS-C3850-24XU-L combines multigigabit copper access with Cisco UPOE on 24 RJ-45 ports supporting 100Mbps, 1Gbps, 2.5Gbps, 5Gbps, and 10Gbps. This managed Layer 2+ switch ships with LAN Base and a 1U rack-mount chassis for enterprise access connections. An empty uplink bay accepts C3850-NM-4-1G for 1G, C3850-NM-8-10G for 10G, or C3850-NM-2-40G for 40G connections, so fiber uplink hardware is not installed in the base configuration. The Catalyst 3850 Series serves wired endpoints such as phones and wireless access points through the same access device. The discontinued WS-C3850-24XU-S sibling instead carries IP Base for routed access. The configuration separates endpoint connectivity from the selected upstream connection, keeping the network feature set and uplink hardware explicit when matching an installed access-switch inventory.
WS-C3850-24XU-L price for new stock is $1,254.75, a 90% saving from the Cisco list price of $12,500.00. WS-C3850-24XU-L refurb price is $504.21. WS-C3850-24XU-L is in stock and available for next-day dispatch. (terms applied)

640 Gbps switching capacity sets the hardware ceiling for access traffic and selected uplinks. 500 Mpps forwarding at 80-byte packets provides the packet-rate figure for traffic planning. Limited static routing is available under the shipped entitlement; full OSPF, EIGRP, and BGP are not included. WS-C3850-24XU-L carries 4 GB of DRAM and 2 GB of flash for Cisco IOS XE and stored configuration. The UADP ASIC supports QoS classification, marking, policing, and shaping, while MSTP and LACP support loop control and link aggregation. Bridged traffic can use 32000 MAC entries. The 24000-entry IPv4 hardware total includes ARP plus learned routes rather than specifying the LAN Base static-route allowance. Cisco Catalyst 3850 administration includes SSH with a cryptographic image, web UI, and local console access; encrypted SNMPv3 requires the cryptographic image as well. Three C3850-FAN-T1= fan modules provide active cooling. DHCP snooping blocks falsified address assignment, and Dynamic ARP Inspection helps prevent ARP poisoning within bridged segments.
Specify WS-C3850-24XU-L condition and quantity on the PO: ORM Systems offers new sealed units with up to 3-year extended ORM warranty coverage and certified refurbished units with up to 1 year. Certified refurbished managed units are inspected and bench-tested, with firmware verified, configuration wiped to factory default, and UPOE output verified under load on every powered port.

A large university deploys the WS-C3850-24XU-L to power and aggregate next-gen 802.11ax access points over 24 multi-gigabit UPoE ports. The LAN Base feature set streamlines VLAN segmentation and QoS policies, boosting wireless throughput by 50% and eliminating network contention during peak hours. Outcome: reliable, high-speed campus connectivity with centralized management and reduced operational overhead.
In a global enterprise HQ, IT teams implement the WS-C3850-24XU-L to power 4K cameras, IP phones, and collaboration devices over UPoE, while multi-gig uplinks deliver low-latency backhaul. Integrated QoS on the LAN Base platform prioritizes voice and video traffic, ensuring jitter-free calls. Outcome: enhanced meeting reliability, 40% faster deployment of conference rooms, and measurable improvements in user satisfaction.
A national retail chain leverages the WS-C3850-24XU-L to power digital signage, IP surveillance, and IoT sensors with 60 W UPoE per port and multi-gigabit data aggregation. LAN Base VLAN segmentation enforces tenant isolation for guest Wi-Fi and secure corporate VLANs. Outcome: improved in-store engagement, 25% uplift in promotional conversions, and simplified compliance with centralized policy enforcement.
An access-point refresh that retains existing copper cabling needs cable qualification rather than a blanket 10G assumption. The multigigabit interfaces support Cat5e for intermediate speeds, while 10Gbps operation calls for Cat6a. Record each run's cable category and negotiated endpoint requirement before specifying the hardware and cabling work on the PO.
A purchase to extend an existing switch stack must account for forwarding-silicon count, not just available rack positions. Each multigigabit member uses four ASIC chips, and a mixed stack cannot exceed 32 ASIC chips. Inventory the existing Catalyst 3850 members and check the resulting ASIC count before ordering an additional unit.
Lab validation for time-synchronized audio and video needs a switch image that includes Audio Video Bridging, rather than assuming every installed release does. Catalyst 3850 multigigabit models support AVB from Cisco IOS XE 16.3 without separate AVB license fees. Specify the required software feature and endpoint interoperability checks for the staging order.
Active Cisco service and security fixes
Cisco service and vulnerability support for WS-C3850-24XU-L ended October 31, 2025. C9300-24U-E is the replacement; validate its access-speed and licensing requirements separately before specifying it.
OSPF or BGP routed access
WS-C3850-24XU-L provides limited static routing under LAN Base and does not include OSPF or BGP. Dynamic routed access therefore requires a different licensed configuration.
More than 60W per endpoint
WS-C3850-24XU-L caps Cisco UPOE delivery at 60W per port. Adding a second PWR-C1-1100WAC increases the shared allocation, not the per-port maximum.

WS-C3850-24XU-L identifies a Catalyst 3850 switch with 24 multigigabit UPOE ports and LAN Base. WS-C3850 denotes the Catalyst 3850 family, 24 denotes the access port count, X denotes multigigabit Ethernet, U denotes Cisco UPOE, and L denotes LAN Base. The configuration includes one PWR-C1-1100WAC and an empty network-module bay.
WS-C3850-24XU-L supports the web UI, Cisco IOS CLI through RJ-45 or USB console, SSH or Telnet, Cisco Network Assistant, Cisco Prime Infrastructure, SNMP, and Cisco DNA Center management. SSH and encrypted SNMPv3 require a cryptographic software image; Cisco DNA Center features depend on the relevant Cisco DNA add-on entitlement.
WS-C3850-24XU-L provides a shared 580W Cisco UPOE budget with its supplied PWR-C1-1100WAC, with a 60W per-port maximum. Two PWR-C1-1100WAC supplies increase the budget to 1680W. Because 24 ports at 60W require 1440W, one PWR-C1-1100WAC cannot power every port at maximum UPOE output simultaneously.
Catalyst 3850 24-port multigigabit switches accept C3850-NM-4-1G, C3850-NM-2-10G, C3850-NM-4-10G, C3850-NM-8-10G, and C3850-NM-2-40G. The base configuration has an empty bay; modules and optics must be specified separately. C3850-NM-8-10G provides eight 10G ports, while C3850-NM-2-40G provides two 40G ports. Select the required module and compatible transceivers before ordering.
Eight multigigabit members can form a Catalyst 3850 StackWise-480 data stack. Each multigigabit member contributes four ASIC chips, and the mixed-stack ceiling is 32 ASIC chips. Use STACK-T1-50CM=, STACK-T1-1M=, or STACK-T1-3M= for data connections; all members must run the same compatible license level.
WS-C3850-24XU-L supports limited static routing under LAN Base, but OSPF, EIGRP, and BGP require higher feature sets. IP Base includes OSPF for routed access; full OSPF, EIGRP, and BGP require IP Services. The 24000-route hardware total includes ARP plus learned routes and is not a LAN Base static-route entitlement.
WS-C3850-24XU-L uses a perpetual LAN Base license; a Cisco DNA subscription is not required for base operation. Cisco DNA Essentials and Cisco DNA Advantage are optional add-on paths with three-year minimum terms; DNA Advantage needs IP Base or IP Services. Add-on expiration leaves base capabilities available after deactivation and a reload.
WS-C3850-24XU-L draws 248.1W at 100% traffic in the tested C3850-NM-8-10G configuration without PoE loading. The same configuration uses 229.7W at zero traffic. These chassis measurements exclude endpoint power, so the 248.1W figure should not be used as a fully loaded UPOE maximum for circuit or UPS sizing.
Catalyst 3850 24-port multigigabit switches use a 1U rack-mount chassis measuring 44.5 mm high, 445 mm wide, and 488 mm deep. The shipped configuration weighs 8 kg before adding uplink hardware. Specify C3850-RAC-KIT= for replacement rack brackets or C3850-4PT-KIT= when the order requires four-point mounting.
WS-C3850-24XU-L is discontinued: end of sale was October 30, 2020, and Cisco service and vulnerability support ended October 31, 2025. These dates apply to this copper multigigabit model, not later support dates for other Catalyst 3850 variants. C9300-24U-E is its replacement for new Cisco hardware procurement.
WS-C3850-24U-L supplies an 800W single-supply PoE budget, compared with 580W for WS-C3850-24XU-L. Both models are discontinued, with Cisco service ending October 31, 2025. Legacy orders needing a larger initial allocation distinguish the former; orders matching the latter must size endpoints against its smaller shared power budget.
WS-C3850-24XU-S ships with IP Base, whereas WS-C3850-24XU-L ships with LAN Base. IP Base adds routed-access capabilities beyond the limited static routing available under LAN Base. Both models are discontinued. Legacy replacement orders retaining primarily bridged configurations can match LAN Base; existing routed-access configurations call for the appropriate IP Base entitlement.
WS-C3850-24XU-L reached the end of Cisco support on October 31, 2025, while C9300-24U-E is its current replacement. The discontinued 3850 model remains relevant to matching legacy hardware inventories. Buyers requiring a current Cisco hardware line should specify the replacement and validate access-speed, licensing, and accessory requirements rather than assuming direct interchangeability.
ORM Systems offers WS-C3850-24XU-L new sealed or certified refurbished, with up to 3-year extended coverage for new units and up to 1 year for refurbished units. All conditions include 30-day returns; terms apply. Cisco's Enhanced Limited Lifetime Warranty service ended October 31, 2025. Refurbished managed units are inspected, bench-tested, firmware verified, and wiped to factory default.
