WS-C3850-24P-L is a managed Layer 2+ enterprise access switch with 24 Gigabit Ethernet PoE+ downlinks and a LAN Base license. The Cisco Catalyst 3850 Series chassis occupies 1U and carries an empty modular uplink bay: C3850-NM-4-1G adds four 1G connections, while C3850-NM-2-10G permits two 10G connections. Phones and wireless access points receive endpoint power from the copper interfaces, subject to shared allocation. The discontinued WS-C3850-24T-L is the nearest data-only sibling and provides no PoE. This 24-port Gigabit PoE+ access switch combines powered endpoint connectivity with selectable uplink hardware rather than an installed, fixed-uplink configuration.
WS-C3850-24P-L price for new stock is $1,732.50. WS-C3850-24P-L refurb price is $182.31. WS-C3850-24P-L is in stock and available for free next-day delivery. (terms applied)

92 Gbps switching capacity sets the standalone forwarding ceiling, and 68.4 Mpps applies to the C3850-NM-2-10G configuration with two 10G and two 1G uplinks. 435W of shared PoE budget supplies powered endpoints within an aggregate allocation. Static routing supports 16 user-configured routes on SVIs under LAN Base; OSPF is not included in this tier. WS-C3850-24P-L provides 4 GB DRAM and 2 GB flash for Cisco IOS XE operation, with a 32000-entry MAC address table for endpoint learning. The UADP ASIC handles forwarding, while three C3850-FAN-T1= fans provide chassis airflow. A second internal power position permits optional redundancy beyond the included PWR-C1-715WAC. 88.32W consumption with C3850-NM-2-10G at full traffic excludes PoE loading, so endpoint power must remain separate from that equipment-only figure when sizing electrical capacity.
WS-C3850-24P-L is offered new sealed or certified refurbished, with ORM coverage of up to a 3-year extended warranty for new units or up to 1 year for certified refurbished units; every condition includes 30-day returns, terms apply. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot and PoE output under load; firmware is verified and configuration wiped to factory default. Specify condition, quantity and accessories on the PO; Cisco's Enhanced Limited Lifetime Warranty and service ended October 31, 2025. For enterprise and volume orders, POs are accepted, government Net-30 is available, and RMA includes advance replacement across UK, EU, US and MEA stock and RMA regions.

In a multi-site enterprise with a remote branch office requiring 24-port PoE support for IP phones and Wi-Fi access points, the Cisco Catalyst 3850-24P-L delivers centralized LAN Base manageability and advanced QoS. By powering up to 24 Cisco IP phones and two wireless controllers or access points, IT teams can deploy a converged voice and wireless network over a single chassis. Benefit: Streamlined cabling, automated PoE provisioning, guaranteed voice quality, and unified management reduce operational costs by up to 30% and accelerate site rollouts.
A nationwide retail chain needs reliable power and data for digital signage, POS terminals, and security cameras in each store location. The WS-C3850-24P-L PoE switch powers high-resolution LED displays, barcode scanners, and IP cameras through a single ethernet run, while the LAN Base feature set enforces ACL-based segmentation and VLAN isolation. Benefit: High-availability PoE, granular traffic control, and easy firmware updates enhance customer experiences, reduce in-store downtime by 40%, and simplify compliance with PCI DSS.
In a manufacturing plant with automated assembly lines, hundreds of sensors, machine-vision cameras, and handheld scanners require power and low-latency connectivity. Deploying the Catalyst 3850-24P-L at each cell controller provides 370W of PoE budget and wire-speed forwarding for real-time data ingestion and video streams. Benefit: Deterministic performance for SCADA integration, dynamic power allocation to mobile robots, and built-in network segmentation improve production efficiency by 25% and strengthen operational security.
When replacement inventory is being standardized after WS-C3750X-24P-L retirement, account for the predecessor's October 30, 2016 end-of-sale milestone rather than treating the change as an in-family part swap. Inventory existing fiber connections and endpoint power assignments, then specify the exact hardware condition and migration quantities on the PO.
When WS-C3850-24P-L is purchased for configuration staging rather than immediate installation, RJ-45 and USB console connections provide local CLI access before remote management is established. Record the required connection method, approved software image and intended configuration on the staging worksheet, then specify the console access requirements before the PO.
A spare-switch purchase must preserve chassis cooling when the second power position is unused. Keep PWR-C1-BLANK= fitted rather than leaving that opening exposed. Specify PWR-C1-BLANK= alongside the condition and spare quantity on the PO, and include inspection of the covered position in the receiving checklist.
Continuing Cisco hardware service eligibility
WS-C3850-24P-L passed its last Cisco support date on October 31, 2025. C9300-24P-E is the current 24-port PoE+ successor for a current-hardware purchase.
Four independent 10G uplink connections
WS-C3850-24P-L supports two 10G uplinks through C3850-NM-2-10G, not four. C3850-NM-4-10G is incompatible with this 24-port Gigabit Ethernet model, regardless of the installed license tier.
Dynamic routing under LAN Base
LAN Base permits 16 user-configured static routes on SVIs, not OSPF. Dynamic routed-access requirements need an IP Base or IP Services license upgrade before deployment.

WS-C3850-24P-L identifies a Catalyst 3850 switch with 24 Gigabit Ethernet PoE+ access ports and the LAN Base feature set. WS-C3850 identifies the family, 24 indicates the port count, P denotes powered PoE+ ports, and L identifies LAN Base. No fixed-uplink code appears in this part number.
WS-C3850-24P-L supports a web UI, CLI through RJ-45 or USB console, remote CLI over SSH or Telnet, SNMP, Cisco Network Assistant and Cisco Prime Infrastructure. SSH and SNMPv3 require the cryptographic software image. Configure administrative credentials and the management address before enabling remote access on an ordered unit.
WS-C3850-24P-L has permanent LAN Base licensing, with optional Cisco DNA Essentials terms starting at three years; Cisco DNA Advantage needs IP Base or IP Services first. RTU applies through Cisco IOS XE 16.8.x; Smart Licensing uses a Smart Account from 16.9.1. The base license does not expire, but add-on terms do.
WS-C3850-24P-L supplies 435W of shared PoE power with PWR-C1-715WAC and supports 30W per powered port. The aggregate budget prevents unrestricted maximum-power allocation across all access ports. Adding PWR-C1-1100WAC in the second bay raises the available power budget to 1535W, while the per-port PoE+ limit remains unchanged.
WS-C3850-24P-L accepts C3850-NM-4-1G for four 1G uplinks or C3850-NM-2-10G for two 10G uplinks with supported 1G combinations. The uplink bay ships empty. C3850-NM-4-10G is not compatible with this 24-port Gigabit Ethernet model, so the selected module must match the exact chassis rather than the series name alone.
WS-C3850-24P-L supports StackWise-480 with nine members and 480 Gbps stacking bandwidth. LAN Base stacks require matching license levels. Data connections use STACK-T1-50CM=, STACK-T1-1M= or STACK-T1-3M=; power sharing uses separately ordered CAB-SPWR-30CM= or CAB-SPWR-150CM=. StackPower groups have four members, so the data and power stack sizes are different.
LAN Base on WS-C3850-24P-L supports 16 user-configured static routes on SVIs, in addition to management default routes. OSPF and other dynamic routing features require a higher license tier. The 24000-route hardware total is a separate scale figure, not the routing entitlement supplied with this LAN Base configuration.
WS-C3850-24P-L ships with one PWR-C1-715WAC and a second power position fitted with PWR-C1-BLANK=. Internal power redundancy is optional, not included as a two-supply configuration. Keep PWR-C1-BLANK= in place until a second supported unit, such as PWR-C1-715WAC=, is installed so the chassis retains its required cooling arrangement.
WS-C3850-24P-L replaced WS-C3750X-24P-L, the Catalyst 3750-X 24-port PoE LAN Base model that reached end of sale on October 30, 2016. Both part numbers are now discontinued. The forward replacement for WS-C3850-24P-L is C9300-24P-E, so a current-generation purchase should not stop at the older intermediate model.
Yes, WS-C3850-24P-L reached end of sale on October 30, 2020 and its last date of Cisco support was October 31, 2025. Cisco service has ended for this PID. C9300-24P-E is the current successor, retaining 24 PoE+ access ports while using Network Essentials rather than LAN Base.
ORM Systems offers WS-C3850-24P-L new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Every condition includes 30-day returns; terms apply. Cisco's Enhanced Limited Lifetime Warranty and Cisco service ended on October 31, 2025.
WS-C3850-24P-L has 24 PoE+ access ports, while the discontinued WS-C3850-24T-L has 24 data-only access ports without PoE. The powered model suits purchases for endpoints requiring switch-supplied power; the data-only model addresses independently powered endpoints. Both are discontinued and should be treated as legacy inventory choices.
WS-C3850-24P-S includes IP Base, while WS-C3850-24P-L includes LAN Base; both discontinued variants retain 24 PoE+ access ports. IP Base adds routed-access capabilities, including OSPF for routed access. LAN Base suits limited static-routing requirements, while the IP Base variant serves legacy installations needing that higher software feature set.
WS-C3850-24P-L passed its last Cisco support date on October 31, 2025, while C9300-24P-E is the current replacement. Both provide 24 PoE+ access ports. The successor addresses current-hardware requirements; the older model remains a legacy inventory match only where an ended Cisco service lifecycle is acceptable.
