WS-C3850-24P-E provides Layer 3 enterprise access switching through 24 Gigabit Ethernet PoE+ RJ-45 ports and an empty modular uplink bay. The 1U chassis belongs to the Catalyst 3850 family and includes the IP Services feature set for advanced enterprise routing. Its copper connections serve IP phones, wireless access points, and other powered endpoints, while optional network modules provide fiber uplinks. Native multigigabit downlinks are absent: endpoint connections operate at 10, 100, or 1000 Mbps. The discontinued WS-C3850-24T-E differs by omitting PoE delivery, separating externally powered endpoint purchases from powered-access requirements. This stackable Gigabit PoE+ access switch uses Cisco IOS XE and three modular fans, so the hardware configuration combines managed access switching with active cooling rather than fanless desktop operation.
WS-C3850-24P-E price for new stock is $2,094.75, a 81.5% saving from the Cisco list price of $11,300.00. WS-C3850-24P-E refurb price is $204.75. WS-C3850-24P-E is in stock and available for next-day dispatch. (terms applied)

92 Gbps switching capacity provides the switching fabric for this access configuration. 68.4 Mpps forwarding is rated with two 10G and two 1G uplinks, so that performance figure accompanies a populated network-module configuration rather than built-in uplink ports. 435W of shared PoE capacity allocates power across connected endpoints instead of reserving the per-port maximum everywhere. OSPF, EIGRP, BGPv4, and IS-ISv4 support advanced IPv4 routing; OSPFv3 and EIGRPv6 provide IPv6 routing, while PIM-SM and PIM-DM handle multicast routing. WS-C3850-24P-E carries 4 GB of DRAM and 2 GB of flash for its operating environment and image storage. The 32000-entry MAC table accommodates learned Ethernet destinations, and the 24000-entry IPv4 scale includes ARP entries and learned routes. Support for 1000 switched virtual interfaces enables routed VLAN interfaces. VRF-Lite separates routing contexts, while hardware-based QoS provides queuing, policing, shaping, and marking for differentiated traffic handling.
WS-C3850-24P-E is offered new sealed or certified refurbished, with ORM warranties of up to 3-year extended coverage for new units and up to 1 year for certified refurbished units; 30-day returns apply to every condition, with terms applying. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed links on every port, and PoE output under load on every powered port; firmware is verified and configurations are wiped to factory default. Cisco's Enhanced Limited Lifetime Warranty and service ended October 31, 2025; specify condition and the complete hardware configuration on the PO. ORM Systems accepts POs, offers Net-30 for government and RMA with advance replacement, and handles enterprise volume orders with regional stock and RMA across UK, EU, US, and MEA.

In a mid-sized corporate office, the Cisco Catalyst 3850 24 Port PoE IP Services switch delivers 24-port 802.3at PoE+ for IP phones and 802.11ac wireless access points. With integrated Layer 3 switching, QoS and Power over Ethernet, IT teams consolidate voice and data onto a single, resilient infrastructure. Outcome: streamlined deployment, guaranteed voice quality, and 30% lower operational costs through centralized management and real-time PoE monitoring.
At a university campus, the WS-C3850-24P-E acts as an aggregation switch for dozens of wireless APs across lecture halls and commons areas. Its IP Services feature set supports advanced multicast routing, dynamic segmentation and Cisco TrustSec® policy enforcement. Outcome: seamless roaming for 5,000+ concurrent users, 99.99% network uptime, and enhanced data security with role-based access control.
In a modern commercial building, the Cisco Catalyst 3850 24 Port PoE IP Services switch powers and manages PoE sensors, badge readers, security cameras and digital signage. With Cisco DNA-enabled automation and analytics, facility managers provision VLANs per device type and monitor PoE budgets in real time. Outcome: rapid IoT roll-out in under 2 days, 25% energy savings via intelligent PoE allocation, and centralized operational insights for predictive maintenance.
When adding a member to an existing IP Services stack, the feature set must match the other members; a mixed LAN Base and IP Services stack is not supported. Specify STACK-T1-50CM=, STACK-T1-1M=, or STACK-T1-3M= for the installed spacing, and verify the member's software state before the PO.
When adjacent switches need a shared power pool, StackPower connects four members using CAB-SPWR-30CM= or CAB-SPWR-150CM=. Power-sharing and redundancy modes reserve capacity differently, so identify each installed supply and planned endpoint demand, select the operating mode, and include the correctly sized power cables on the PO.
When staging replacement hardware from an unheated storage area, a cold start requires at least 0°C even though operation can continue below freezing. Treat initial boot conditions separately from the installed room's operating range, and confirm staging temperatures, rack position, and configuration-loading arrangements before ordering the batch.
Ongoing Cisco manufacturer support
Cisco service for WS-C3850-24P-E ended October 31, 2025. C9300-24P-A is its named 24-port PoE+ replacement for purchases requiring a move beyond discontinued hardware.
25G or 40G uplinks
WS-C3850-24P-E accepts C3850-NM-4-1G and C3850-NM-2-10G, limiting uplinks to 10G. The chassis cannot meet a requirement for 25G or 40G uplink interfaces.
60W power per endpoint
WS-C3850-24P-E supplies a maximum of 30W per powered port. Endpoints requiring 60W exceed that per-port limit, regardless of additional internal supply capacity.

WS-C3850-24P-E identifies a stackable Catalyst 3850 switch: WS-C3850 names the family, 24 indicates 24 Ethernet access ports, P indicates PoE+, and E identifies IP Services. The configuration includes PWR-C1-715WAC and a 1U chassis. The uplink network module is selected separately rather than encoded as an installed interface configuration.
The Catalyst 3850 supports console CLI, remote CLI through SSH or Telnet, SNMP management, and Cisco Prime Infrastructure; optional Cisco DNA packages add Cisco DNA Center management. SSH and encrypted SNMPv3 require a cryptographic software image. Specify the intended image and centralized management arrangement with the hardware configuration.
Yes, WS-C3850-24P-E reached end of sale on October 30, 2020, and its last date of support was October 31, 2025. Cisco manufacturer service has ended. C9300-24P-A is the named replacement, so remaining-stock purchases should not be treated as purchases of hardware with continuing Cisco support.
ORM offers WS-C3850-24P-E new sealed with up to 3-year extended warranty or certified refurbished with up to 1-year warranty. Returns are available for 30 days in either condition; terms apply. Cisco's original Enhanced Limited Lifetime Warranty and manufacturer service ended October 31, 2025. Certified refurbished units are inspected, bench-tested, firmware verified, and reset.
No, WS-C3850-24P-E can operate with its IP Services base license without a Cisco DNA subscription. Cisco DNA Essentials and Cisco DNA Advantage are optional add-ons with a minimum three-year term and a five-year option. Expired add-ons must be renewed or deactivated, followed by a reload to retain base-license operation.
WS-C3850-24P-E is the named replacement for discontinued WS-C3750X-24P-E, whose end-of-sale date was October 30, 2016. That migration relationship does not make the destination current: WS-C3850-24P-E subsequently passed its own support cutoff. C9300-24P-A is the next named replacement in the hardware migration chain.
WS-C3850-24P-E provides a shared 435W PoE budget with PWR-C1-715WAC, with a maximum of 30W per powered port. Adding PWR-C1-1100WAC raises the available budget to 1535W without changing that per-port limit. Specify endpoint demand and supply configuration together rather than assuming every port receives maximum power from the default supply.
WS-C3850-24P-E accepts C3850-NM-4-1G and C3850-NM-2-10G, and the base chassis includes neither module. C3850-NM-4-1G provides four Gigabit SFP interfaces. C3850-NM-2-10G supports two 10G SFP+ interfaces with two Gigabit interfaces, or four Gigabit interfaces. Select the module for the required uplink speed before specifying compatible transceivers.
StackWise-480 stacks nine Catalyst 3850 members with 480 Gbps of stacking bandwidth and management through a single switching entity. STACK-T1-50CM=, STACK-T1-1M=, and STACK-T1-3M= provide the stacking cable options. Member feature sets must match; a mixed LAN Base and IP Services stack is not supported.
Yes, WS-C3850-24P-E includes IP Services for full OSPF and BGPv4, together with EIGRP and IS-ISv4. OSPFv3 and EIGRPv6 support IPv6 routing, while PIM-SM and PIM-DM support multicast. The 24000-entry IPv4 capacity includes ARP entries and learned routes rather than representing an isolated dynamic-routing protocol limit.
No, WS-C3850-24P-E ships with one PWR-C1-715WAC, while the second internal supply position remains available for an optional purchase. The single installed supply belongs in bay 1. Adding another supply changes the power configuration, so specify the intended redundancy arrangement and endpoint power requirements together on the PO.
WS-C3850-24P-E consumes 88.32W in the tested configuration with C3850-NM-2-10G, full traffic, and no PoE loading. That measurement excludes power delivered to endpoints and is not a total loaded-system maximum. Electrical planning must therefore account separately for endpoint demand and the selected supply configuration.
WS-C3850-24P-E supplies PoE+ to connected endpoints, whereas discontinued WS-C3850-24T-E provides data-only access ports. Both variants have 24 Gigabit Ethernet access connections. The powered model suits legacy inventories with phones or access points requiring switch-delivered power; the data-only variant suits replacement requirements where endpoints have separate power sources.
WS-C3850-24P-E includes IP Services, whereas discontinued WS-C3850-24P-S includes IP Base. IP Services enables full OSPF, EIGRP, BGPv4, and IS-ISv4; IP Base includes OSPF for routed access. The former fits advanced-routing replacement requirements, while the latter fits an existing IP Base deployment that does not require those additional routing features.
C9300-24P-A is the named replacement for WS-C3850-24P-E, whose Cisco service ended October 31, 2025. The replacement is a 24-port PoE+ model with Network Advantage rather than IP Services. WS-C3850-24P-E fits legacy hardware sparing, while C9300-24P-A fits buyers moving to the replacement family instead of retaining discontinued hardware.
