WS-C3850-24U-E provides Cisco UPOE at a maximum of 60W per powered port, combining 24 Gigabit Ethernet copper connections with managed Layer 3 enterprise access switching. The chassis occupies one rack unit and ships with an empty modular uplink bay, rather than installed fiber uplinks. C3850-NM-4-1G provides four Gigabit Ethernet SFP connections; C3850-NM-2-10G supports two 10G SFP+ connections alongside two Gigabit Ethernet connections. The Cisco Catalyst 3850 serves campus access deployments connecting computers, IP phones, wireless access points and compatible higher-power endpoints. Its IP Services feature set includes advanced IPv4 and IPv6 routing rather than only basic routed access. The discontinued WS-C3850-24P-E differs on endpoint power, providing PoE+ instead of UPOE. This configuration therefore separates the endpoint power requirement from the uplink module selection.
WS-C3850-24U-E price for new stock is $1,989.75, a 83.1% saving from the Cisco list price of $11,800.00. WS-C3850-24U-E refurb price is $267.75. WS-C3850-24U-E is in stock and available for next-day dispatch. (terms applied)

92 Gbps switching capacity defines the forwarding fabric for this 24-port Gigabit configuration. 800W of shared PoE power is available from the default PWR-C1-1100WAC, so endpoint allocations must remain within the aggregate budget. OSPF, EIGRP, BGPv4 and IS-ISv4 support dynamic IPv4 routing, while OSPFv3 and EIGRPv6 extend routing to IPv6 networks. PIM-SM, PIM-DM and SSM provide multicast routing choices, and VRF-Lite separates routing contexts. WS-C3850-24U-E carries 4 GB of DRAM and 2 GB of flash for software operation and storage. The Catalyst 3850 supports 32000 MAC addresses and a total of 24000 IPv4 ARP and learned-route entries. Flexible NetFlow accommodates 24000 flow entries on this hardware configuration. Administrators can configure the switch through the console or remote CLI and use Cisco Prime Infrastructure for centralized management. LACP aggregates Ethernet links, while MSTP controls Layer 2 topology. MACsec supports 128-bit encryption; 256-bit MACsec is not available on this Gigabit Ethernet model.
ORM Systems offers WS-C3850-24U-E new sealed with up to a 3-year extended warranty or certified refurbished with up to a 1-year warranty; every condition includes 30-day returns, with terms applying. Certified refurbished units are inspected and bench-tested for power-on, POST, clean boot and rated-speed port links, with PoE output verified under load on every powered port, firmware verified and configuration wiped to factory default. Specify the required condition and complete accessory configuration before submitting the PO; Cisco's original Enhanced Limited Lifetime Warranty support ended October 31, 2025. For enterprise and volume orders, POs are accepted, Net-30 is available for government, and RMA includes advance replacement across UK, EU, US and MEA regional stock and RMA operations.

Benefits include rapid store rollouts under 48 hours, segmented network security for PCI compliance, and real-time inventory and promotion updates that boost sales conversion by 15%.
An existing WS-C3750X-24U-E installation can use WS-C3850-24U-E as its named hardware replacement while retaining the IP Services feature tier. The older model reached end of sale on October 30, 2016. Before issuing the PO, verify the replacement chassis configuration and identify the uplink module and accessories required for the changeover.
A replacement member for an existing IP Services stack must match the other members' software feature set; mixed feature sets are not supported. Select STACK-T1-50CM=, STACK-T1-1M= or STACK-T1-3M= for the required connection length, and verify the complete stack's license alignment and cable routing before adding the replacement to the PO.
Equipment arriving at a cold staging location needs a controlled startup plan because the minimum ambient temperature for a cold start is 0°C. Higher installation altitudes also change the normal operating temperature limit. Confirm the site's altitude, startup environment and rack placement before specifying the chassis for the shipment.
Cisco-backed support for new deployments
WS-C3850-24U-E passed its last date of support on October 31, 2025. C9300-24U-A is the named replacement, retaining 24 UPOE ports with Network Advantage.
Four simultaneous 10G uplink connections
WS-C3850-24U-E supports a maximum of two 10G uplinks through C3850-NM-2-10G. C3850-NM-4-10G is not compatible with this 24-port Gigabit Ethernet model.
Multigigabit copper connections for endpoints
WS-C3850-24U-E copper access ports operate at 10Mbps, 100Mbps or 1Gbps. Endpoints requiring 2.5Gbps, 5Gbps or 10Gbps copper access need a different switch configuration.

WS-C3850-24U-E identifies a Catalyst 3850 switch with 24 UPOE access ports and the IP Services feature set: WS-C3850 identifies the switch family, 24 gives the port count, U identifies UPOE, and E identifies IP Services. The configuration includes a PWR-C1-1100WAC and a modular uplink bay.
WS-C3850-24U-E supports console CLI access, remote CLI access through SSH or Telnet, SNMP management, and centralized management through Cisco Prime Infrastructure. SSH and cryptographic SNMPv3 require the appropriate cryptographic software image. A hardware stack can be administered through a single IP address and CLI session.
Yes, WS-C3850-24U-E reached end of sale on October 30, 2020, and its last date of support was October 31, 2025. Cisco hardware service and warranty support have ended. C9300-24U-A is the named replacement, providing a 24-port UPOE configuration with the Network Advantage license tier.
ORM Systems offers WS-C3850-24U-E new sealed with up to a 3-year extended warranty, or certified refurbished with up to a 1-year warranty. Returns cover every condition for 30 days; terms apply. Cisco's original Enhanced Limited Lifetime Warranty support ended October 31, 2025, independently of ORM's order warranty.
No, WS-C3850-24U-E uses a perpetual IP Services base license without a required term subscription. Optional Cisco DNA Essentials and Cisco DNA Advantage add-ons were offered with three- or five-year terms, making three years the minimum. At expiry, renew the add-on or deactivate it and reload to retain base capabilities.
WS-C3850-24U-E is the named replacement for WS-C3750X-24U-E, preserving the 24-port UPOE configuration and IP Services feature tier. WS-C3750X-24U-E reached end of sale on October 30, 2016. The replacement chassis uses its own uplink module choices, so include the required module selection when planning the hardware changeover.
WS-C3850-24U-E provides an 800W shared PoE budget with its default PWR-C1-1100WAC and supports Cisco UPOE at a maximum of 60W per port. Two PWR-C1-1100WAC supplies raise the available budget to 1900W. The single-supply configuration does not support simultaneous maximum UPOE output on all 24 ports.
WS-C3850-24U-E accepts C3850-NM-4-1G and C3850-NM-2-10G, and neither module is included in the default chassis configuration. C3850-NM-4-1G provides four Gigabit Ethernet SFP ports. C3850-NM-2-10G supports two 10G SFP+ ports plus two Gigabit Ethernet connections, or four Gigabit Ethernet connections. Select compatible optics for the required link.
StackWise-480 stacks nine compatible Catalyst 3850 members with 480 Gbps of stack bandwidth. Members must use matching software feature sets. Data-stack cable choices are STACK-T1-50CM=, STACK-T1-1M= and STACK-T1-3M=. StackPower is a separate power-sharing connection supporting four members, using CAB-SPWR-30CM= or CAB-SPWR-150CM= rather than data-stack cables.
WS-C3850-24U-E includes full OSPF, EIGRP, BGPv4 and IS-ISv4 through IP Services, plus OSPFv3 and EIGRPv6 for IPv6 routing. PBR, VRF-Lite and multicast routing through PIM-SM, PIM-DM and SSM are also supported. These are base-tier capabilities, rather than features that require a Cisco DNA subscription.
Yes, the Catalyst 3850 24-port UPOE configuration uses a one-rack-unit chassis measuring 44.5 mm high, 445 mm wide and 488 mm deep. Its shipped weight is 7.5 kg without an uplink module. C3850-RAC-KIT= is the rack mounting kit, while C3850-4PT-KIT= provides extension rails and brackets for four-point mounting.
No, WS-C3850-24U-E ships with one PWR-C1-1100WAC; the second internal supply bay is available for an optional additional supply. A single installed supply belongs in bay 1. PWR-C1-1100WAC plus PWR-C1-715WAC supports 60W UPOE on all 24 ports, while a second PWR-C1-1100WAC increases the available PoE budget to 1900W.
WS-C3850-24U-E supports 60W Cisco UPOE per port, whereas the discontinued WS-C3850-24P-E supports 30W PoE+ per port. Both configurations carry IP Services. Existing installations with compatible higher-power endpoints call for the UPOE model; environments retaining endpoints within PoE+ limits can distinguish the PoE+ configuration by that lower per-port power capability.
WS-C3850-24U-E includes IP Services, whereas the discontinued WS-C3850-24U-S includes IP Base. IP Services adds full OSPF, EIGRP, BGPv4, IS-ISv4 and VRF-Lite beyond the IP Base routing tier. Retained deployments needing those advanced routing functions require IP Services; existing basic routed-access configurations use the IP Base tier.
WS-C3850-24U-E carries the IP Services feature tier, while its named replacement C9300-24U-A carries Network Advantage; both are 24-port UPOE configurations. Cisco support for the discontinued model ended October 31, 2025. Retaining an existing Catalyst 3850 configuration differs from purchasing the successor for a new supported hardware deployment.
