WS-C3850-24T-S is a Layer 3, 24-port 10/100/1000 copper access switch for enterprise wiring closets, supplied as a 1U Catalyst 3850 member with IP Base software. The base chassis has a modular uplink bay rather than fixed fiber uplinks; C3850-NM-4-1G or C3850-NM-2-10G must be specified when uplink ports are required. The Cisco Catalyst 3850 switch family is managed through a CLI, a single console port, Telnet, SSH, SNMPv3, Cisco Prime Infrastructure and a single IP address for a StackWise-480 stack. WS-C3850-24P-S keeps the same 24-port IP Base access position but changes the downlinks to PoE+ and ships with PWR-C1-715WAC for powered endpoints.
WS-C3850-24T-S price for new stock is $722.40, a 88.9% saving from the Cisco list price of $6,500.00. WS-C3850-24T-S refurb price is $120.75. WS-C3850-24T-S is in stock and available for next-day dispatch. (terms applied)

92 Gbps switching capacity and 68.4 Mpps forwarding support the 24-port Gigabit Ethernet model when configured with 2 x 10G and 2 x 1G uplinks. 480 Gbps StackWise-480 bandwidth links up to nine members, and IP Base stacks must stay with IP Base members. WS-C3850-24T-S carries 4 GB DRAM, 2 GB flash, 32000 MAC addresses and 24000 IPv4 routes. Static, RIPv1, RIPv2, RIPng, EIGRP stub, OSPF for routed access and PBR are available under IP Base; full OSPF, EIGRP, BGPv4, IS-ISv4, VRF-Lite and PIM require IP Services. Mobility Agent is the default wireless role, while mobility controller mode is enabled from the CLI and requires IP Base plus access point licensing. The 24-port model supports 20 Gbps wireless bandwidth, 100 access points, 2000 wireless clients, 64 WLANs, 1000 SVIs, 4000 VLAN IDs and 24000 FNF entries.
WS-C3850-24T-S is available from ORM Systems new sealed or certified refurbished; specify condition, warranty term and any spare power supply on the PO. Refurbished managed units are inspected and bench-tested; firmware is verified, configuration is wiped to factory default, every RJ-45 port links at rated speed, module bay recognition is checked, StackWise-480 adapter negotiation is tested, and PSU and fan status are verified. New units can carry up to a 3-year extended ORM warranty, certified refurbished units up to 1 year, and every condition has 30-day returns with terms applying; PO accepted, Net-30 for government, RMA with advance replacement, and regional stock and RMA coverage in UK, EU, US and MEA.

Scenario: In a multi-building enterprise campus supporting 500+ users, the WS-C3850-24T-S is deployed at the access layer to deliver 24 Gigabit Ethernet ports, PoE+ for VoIP phones and wireless APs, advanced QoS for voice/video prioritization, and Cisco StackWise-Plus stacking. Outcome: Scalable, high-performance edge switching that simplifies management, ensures sub-millisecond failover, and enhances overall user experience.
Scenario: A nationwide retail chain equips each store with the WS-C3850-24T-S to power point-of-sale terminals, IP surveillance cameras, and Wi-Fi access points over 24 PoE+ ports, while leveraging secure VLAN segmentation and centralized Cisco DNA Center monitoring. Outcome: Lower installation and operating costs, consistent network uptime, and unified security policy enforcement across 150+ locations.
Scenario: In a smart building deployment, the WS-C3850-24T-S aggregates IoT sensors, lighting controls, environmental monitors, and tenant devices on a single switch using 802.1X authentication, Cisco TrustSec segmentation, and Flexible NetFlow analytics. Outcome: A secure, converged network that delivers granular policy enforcement, real-time visibility, and reduced operational complexity.
A site standardizing beyond WS-C3750X-24T-S can keep 24-port data-only IP Base access while moving to the Catalyst 3850 form factor. Confirm the 31 October 2025 Cisco support boundary, then check uplink module needs and estate software alignment before the PO.
An installed StackWise-480 access stack can add a matching IP Base member when the license level remains uniform. Check the nine-member StackWise-480 limit, cable length requirements and physical stack layout before specifying stack cables for the installation.
A campus with deployed Catalyst 3850 24-port copper switches may need spares after Cisco last-date support. Match PWR-C1-350WAC, confirm any installed network module, and choose certified refurbished condition when estate compatibility outranks a platform change.
PoE endpoint power
The 24 access ports are data-only with no PoE budget; use the current C9300-24P-A successor path for 24-port PoE+ access.
Full enterprise routing
IP Base limits routing to static, RIPv1, RIPv2, RIPng, EIGRP stub and OSPF routed access; C9300-24T-A is the current successor path for Network Advantage.
Fixed uplinks included
The base chassis ships without uplink ports; specify C3850-NM-4-1G or C3850-NM-2-10G, or choose a current platform with fixed uplinks if that is mandatory.

WS-C3850-24T-S identifies a stackable Catalyst 3850 switch with 24 10/100/1000 Ethernet data ports, PWR-C1-350WAC power and the IP Base feature set. The suffix marks the IP Base software variant; the base chassis does not include fixed uplinks or PoE.
WS-C3850-24T-S is managed through Cisco IOS XE CLI access, console, Telnet, SSH, SNMPv3 and Cisco Prime Infrastructure. A StackWise-480 stack presents a single IP address, single Telnet session and single CLI, while Cisco Smart Install and DHCP autoconfiguration support deployment workflows.
WS-C3850-24T-S is end-of-sale, with Cisco last date of support on 31 October 2025. The hardware end-of-sale date was 30 October 2020, last ship date was 29 January 2021, and the replacement PID named for this IP Base model is C9300-24T-A.
WS-C3850-24T-S is offered by ORM Systems new sealed or certified refurbished, while Cisco E-LLW support for the platform ended on 31 October 2025. ORM new units can include up to a 3-year extended warranty, certified refurbished units up to 1 year, and every condition has 30-day returns.
WS-C3850-24T-S ships with IP Base and can be upgraded to IP Services through C3850-24-S-E or L-C3850-24-S-E RTU licenses. SD-Access add-ons use Cisco DNA Essentials or Cisco DNA Advantage for 24-port switches, including 3-year and 5-year terms.
WS-C3850-24T-S is named as the replacement for WS-C3750X-24T-S, the Catalyst 3750X 24 Port Data IP Base model. That older product reached end of sale on 30 October 2016 and last date of support on 31 October 2021.
WS-C3850-24T-S supports C3850-NM-4-1G and C3850-NM-2-10G network modules. The default configuration includes no network module, so uplink cages appear only when one of those modules is installed; C3850-NM-4-10G, C3850-NM-8-10G and C3850-NM-2-40G are not supported on 24-port Gigabit Ethernet data models.
Catalyst 3850 StackWise-480 stacks up to nine switches and provides 480 Gbps of stacking bandwidth. Stack members must share the same feature set, so IP Base units stack with IP Base units; physical stack cabling uses STACK-T1-50CM=, STACK-T1-1M= or STACK-T1-3M=.
Yes, WS-C3850-24T-S supports Layer 3 routing under IP Base, including static, RIPv1, RIPv2, RIPng, EIGRP stub, OSPF for routed access and PBR. Full OSPF, EIGRP, BGPv4, IS-ISv4, VRF-Lite and PIM require the IP Services feature set.
WS-C3850-24T-S ships with one PWR-C1-350WAC power supply and has a second power-supply bay for optional redundancy. PWR-C1-440WDC is also available as a configuration option, and PWR-C1-BLANK= is listed as the spare blank for an empty bay.
WS-C3850-24P-S provides 24 10/100/1000 PoE+ ports with PWR-C1-715WAC, while WS-C3850-24T-S provides 24 10/100/1000 data-only ports with PWR-C1-350WAC. Choose WS-C3850-24P-S for powered endpoints; choose WS-C3850-24T-S for copper access ports where endpoint power is not required.
WS-C3850-24T-E uses the IP Services feature set, while WS-C3850-24T-S uses IP Base on the same 24-port 10/100/1000 data chassis. Choose WS-C3850-24T-E for the advanced Layer 3 license; choose WS-C3850-24T-S for IP Base routed access.
C9300-24T-A is the named replacement with Catalyst 9300 24-port data-only Network Advantage licensing, while WS-C3850-24T-S is the Catalyst 3850 24-port data IP Base model. Choose C9300-24T-A for the replacement path; choose WS-C3850-24T-S only for like-for-like Catalyst 3850 estate matching.
