WS-C3850-48P-L is a managed, stackable enterprise access switch with 48 copper 10/100/1000 Mbps PoE+ ports and LAN Base software. The supplied feature set provides Layer 2+ operation for access connections. Its 1U rack chassis belongs to the Cisco Catalyst 3850 Series and connects powered phones, wireless access points and other compatible endpoints. An empty modular uplink bay accepts C3850-NM-4-1G, C3850-NM-2-10G or C3850-NM-4-10G; no uplink module is installed in the base configuration. The discontinued WS-C3850-48F-L differs by supplying an 800W PoE budget with PWR-C1-1100WAC. This 48-port Gigabit PoE+ access switch separates endpoint connectivity from uplink selection, so the purchase configuration must account for both the distribution-facing connections and the power allocation required by attached devices.
WS-C3850-48P-L price for new stock is $1,589.70. WS-C3850-48P-L refurb price is $119.70. WS-C3850-48P-L is in stock and available for free next-day delivery. (terms applied)

176 Gbps switching capacity covers the maximum port configuration, while 130.95 Mpps forwarding applies with C3850-NM-4-10G providing four 10G uplinks. 435W of shared PoE allocation requires endpoint demand to be sized separately from the number of powered ports. Static routing is limited under the included feature set; full OSPF, EIGRP, BGPv4 and IS-ISv4 are not included. WS-C3850-48P-L carries 4 GB of DRAM and 2 GB of flash for software and configuration storage. The UADP ASIC supplies the forwarding engine, and the MAC table holds 32000 entries. Jumbo frames reach 9198 bytes, establishing a frame-size ceiling for MTU planning. MSTP and PVRST+ handle spanning-tree convergence, while LACP supports aggregated connections. Management uses the CLI and Cisco Prime infrastructure; SSH and encrypted SNMPv3 require a cryptographic image. Three fans provide active cooling, so the installation is not fanless and requires an airflow plan appropriate to a powered rack installation.
WS-C3850-48P-L is offered new sealed or certified refurbished, with ORM coverage leading because Cisco's Enhanced Limited Lifetime Warranty and service ended October 31, 2025. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, every port linking at rated speed and PoE output under load on every powered port; firmware is verified and configurations are wiped to factory default. Specify the condition and required accessories on the PO: new units carry up to a 3-year extended warranty, certified refurbished units up to 1 year, and every condition includes 30-day returns, terms apply. Enterprise and volume orders can use accepted POs, government Net-30, RMA with advance replacement and regional stock/RMA across the UK, EU, US and MEA.

In a 1,500-seat enterprise campus, network engineers deploy the Cisco Catalyst 3850 48 Port PoE LAN Base (WS-C3850-48P-L) as the primary access layer switch to power IP phones, thin clients, and desktop PCs over a single Ethernet fabric. Leveraging integrated PoE+ and industry-leading QoS on IOS-XE, the solution enforces voice-priority traffic and delivers consistent 99.999% uptime via stackable resiliency. Outcome: simplified network operations, guaranteed voice quality, and a 30% reduction in cabling and power infrastructure costs.
A large university deploys up to 48 PoE wireless access points per floor, powered and aggregated through the WS-C3850-48P-L Cisco Catalyst 3850 switch. Using Cisco’s LAN Base feature set and Unified Access Data Plane (UADP) ASIC, network administrators centralize SSID provisioning, apply RF-aware load balancing, and ensure seamless roaming across buildings. Outcome: scalable high-performance Wi-Fi for 10,000 daily users, streamlined roll-out in under two weeks, and a 40% improvement in client throughput.
In a smart office tower, security and facilities teams install 48 IP cameras, environmental sensors, and door controllers powered by a single WS-C3850-48P-L switch per floor. With Cisco TrustSec microsegmentation and 740W PoE budget, each network segment is isolated, and critical data streams receive latency-sensitive treatment. Outcome: end-to-end encryption for all edge devices, 50% faster deployment of security assets, and future-proof capacity for additional IoT integrations.
Where an endpoint rollout calls for 30W at every powered port, size the supply configuration before selecting condition or quantity. The full PoE+ power arrangement uses PWR-C1-1100WAC with PWR-C1-715WAC, or two PWR-C1-1100WAC supplies. Specify the second supply and verify the endpoint allocation on the PO.
During an expansion that also needs shared power, plan the power topology separately from the data stack. StackPower groups four switches and uses CAB-SPWR-30CM= or CAB-SPWR-150CM=, rather than the data-stacking cables. LAN Base orders exclude these power cables, so specify the required interconnect lengths before issuing the PO.
When a staged configuration contains more than 255 VLANs, the included feature set cannot accommodate the intended VLAN count. Prepare the lab configuration against the licensed limit rather than the larger VLAN identifier space. Verify whether an existing IP Base or IP Services entitlement is part of the order before approving the staging configuration.
Ongoing Cisco service and security fixes
WS-C3850-48P-L service and scheduled security support ended October 31, 2025. C9300-48P-E is the current 48-port PoE+ migration replacement for purchases requiring an active product lifecycle.
Native multigigabit copper access connections
WS-C3850-48P-L fixed copper access ports top out at 1 Gbps. A faster removable uplink module does not increase endpoint link speed beyond that downlink limit.
Full dynamic routing with the included license
WS-C3850-48P-L supplies limited static routing with LAN Base. Full OSPF, EIGRP, BGPv4 and IS-ISv4 require IP Services rather than the supplied network feature set.
40G distribution uplink connections
WS-C3850-48P-L supports C3850-NM-4-10G as its fastest uplink option, with four 10G ports; its permitted module choices do not provide 40G connectivity.

WS-C3850-48P-L identifies a Catalyst 3850 switch: the WS-C3850 segment identifies the family, 48 indicates the copper access-port count, P identifies the PoE+ configuration supplied with PWR-C1-715WAC, and L identifies LAN Base. The part number contains no uplink-module designation, and the base configuration excludes an uplink module.
WS-C3850-48P-L runs Cisco IOS XE and supports CLI management through the console, SSH or Telnet, plus Cisco Prime infrastructure and SNMP monitoring. Optional Cisco DNA packages add centralized management functions through Cisco DNA Center. SSH and encrypted SNMPv3 require the cryptographic software image.
WS-C3850-48P-L provides a shared 435W PoE budget with PWR-C1-715WAC. Adding PWR-C1-1100WAC raises the available budget to 1535W. Individual PoE+ ports support 30W, but available power must be allocated across connected endpoints rather than assumed from the port count or the maximum rating of each powered port.
C3850-NM-4-1G, C3850-NM-2-10G and C3850-NM-4-10G are the uplink choices for WS-C3850-48P-L. The base configuration has an empty uplink bay, not fixed fiber uplinks. C3850-NM-4-10G supplies four 10G-capable SFP+ ports; the module and matching optics must be included separately on the order.
StackWise-480 stacks nine Catalyst 3850 members with 480 Gbps stack bandwidth, and WS-C3850-48P-L requires LAN Base-compatible membership. Data cables are STACK-T1-50CM=, STACK-T1-1M= or STACK-T1-3M=. StackPower is separate: four-member power groups require CAB-SPWR-30CM= or CAB-SPWR-150CM=, purchased separately for LAN Base orders.
No, WS-C3850-48P-L supports limited static routing with LAN Base, placing the supplied configuration at Layer 2+. Full OSPF, EIGRP, BGPv4 and IS-ISv4 require IP Services, while routed-access OSPF is an IP Base feature. Routing entitlement must be established separately from physical port and uplink selection.
WS-C3850-48P-L includes LAN Base, with RTU upgrades to IP Base or IP Services and optional Cisco DNA Essentials or Cisco DNA Advantage add-ons starting at a 3-year term. Smart Accounts manage add-ons. Expiration requires renewal or deactivation and a reload to retain base capabilities. Cisco ONE was also offered.
WS-C3850-48P-L replaced the discontinued WS-C3750X-48P-L, which reached end of sale on October 30, 2016. The earlier model was a 48-port PoE LAN Base switch. WS-C3850-48P-L is also discontinued, so a current migration purchase should be specified against C9300-48P-E.
Yes, WS-C3850-48P-L is discontinued: Cisco sales ended October 30, 2020, and its last date of support was October 31, 2025. Cisco service and scheduled security fixes have ended for this model. C9300-48P-E is the current replacement for migration planning.
WS-C3850-48P-L provides 435W of PoE allocation, while WS-C3850-48F-L provides 800W. Both are discontinued 48-port Gigabit PoE+ models with LAN Base. For legacy purchases, the first suits lower aggregate endpoint demand; the second suits a larger shared power requirement without changing the access-port count.
WS-C3850-48P-L includes LAN Base with limited static routing and 255 VLANs; WS-C3850-48P-S includes IP Base with routed-access OSPF and 1000 VLANs. Both models are discontinued. LAN Base serves basic access requirements; IP Base serves legacy deployments needing routed-access protocols and the larger licensed VLAN allowance.
C9300-48P-E is the current migration replacement for the discontinued WS-C3850-48P-L, whose Cisco support ended October 31, 2025. The successor preserves a 48-port PoE+ access configuration. C9300-48P-E suits migration purchases; WS-C3850-48P-L serves like-for-like legacy replacement requirements where discontinued hardware is explicitly accepted.
No, WS-C3850-48P-L ships with one PWR-C1-715WAC, leaving the second internal supply bay available for an additional supply. Redundant power is optional rather than included as standard. Install a single supply in bay 1; specify any added PWR-C1-715WAC or PWR-C1-1100WAC separately, with the endpoint power plan attached.
No, WS-C3850-48P-L-RF identifies Cisco-remanufactured WS-C3850-48P-L hardware, not ORM-certified refurbishment. ORM's process is separate inspection and bench testing with firmware verification and a factory-default configuration wipe. A Cisco DNA add-on is optional for base-license operation; an ORM hardware order does not make an add-on subscription mandatory.
New sealed and certified refurbished WS-C3850-48P-L units carry ORM warranties: up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units. Every condition includes 30-day returns, terms apply. Cisco's Enhanced Limited Lifetime Warranty and service ended October 31, 2025. Refurbished units are inspected and bench-tested.
