WS-C3850-48UW-S is a managed Layer 3 enterprise access switch with 48 10/100/1000 RJ-45 ports and Cisco UPOE for powered endpoints. Its 1U rack-mount chassis belongs to the Cisco Catalyst 3850 Series and provides an empty modular uplink bay rather than fixed fiber uplinks. Compatible network modules add 1G or 10G connectivity without changing the native access-port speed. IP Base supplies the included network feature set, while the wireless-license bundle distinguishes this configuration from the standard UPOE hardware order. This 48-port Gigabit UPOE access switch connects wired clients, access points and compatible powered devices within a shared power allowance. The discontinued WS-C3850-48PW-S uses PoE+ instead of UPOE, separating the two wireless-license bundles by endpoint power class.
WS-C3850-48UW-S price for new stock is $2,649.15, a 85% saving from the Cisco list price of $17,717.00. WS-C3850-48UW-S refurb price is $147.00. WS-C3850-48UW-S is in stock and available for next-day dispatch. (terms applied)

176 Gbps switching capacity supports local traffic forwarding across the access interfaces. 800W of shared endpoint power is available with the supplied PWR-C1-1100WAC; a second PWR-C1-1100WAC raises the available PoE budget to 1900W. OSPF for routed access, Static, RIPv1, RIPv2, RIPng, EIGRP Stub and PBR are included under IP Base; full EIGRP, BGPv4 and IS-ISv4 require IP Services. WS-C3850-48UW-S carries 4 GB DRAM and 2 GB flash for software operation and storage. The UADP ASIC supports 32000 MAC entries and a total IPv4 scale of 24000 ARP plus learned routes, separate from license-specific routing capabilities. CLI administration, Cisco Prime Infrastructure and SNMP provide configuration and monitoring paths. LACP aggregates Ethernet links, while MSTP handles spanning-tree operation. Three modular fans provide active cooling, with C3850-FAN-T1= available as the replacement fan spare. The second internal supply bay is optional rather than populated by default.
ORM Systems offers WS-C3850-48UW-S new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year; every condition includes 30-day returns, terms apply, and Cisco hardware warranty support ended October 31, 2025. Certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified and configuration wiped to factory default. Specify the required condition, accessories and quantities on the purchase order before placing an order for this switch. Enterprise and volume purchases support PO acceptance, Net-30 for government and RMA with advance replacement across regional stock and RMA operations in the UK, EU, US and MEA.

Scenario: A 200-user corporate office requires unified wired and wireless connectivity with IP phones and Wi-Fi access points. Deploy the WS-C3850-48UW-S-CATALYST 3850 (48-port UPoE, IP Base) with five included AP licenses to power VoIP phones and five Cisco Air-onet access points. Outcome: Simplified single-pane-of-glass management, 60W per port UPoE for high-density devices, 10Gb uplink performance and seamless mobility deliver 30% faster deployment and 25% lower TCO.
Scenario: A manufacturing facility implements real-time asset tracking, environmental sensors and LED lighting controls over PoE. The WS-C3850-48UW-S (48-port UPoE, IP Base) supplies power and data to 48 IoT endpoints plus five Wi-Fi 6 access points under the included AP licenses. Outcome: Centralized PoE power and network segmentation improve operational visibility by 40%, reduce cabling complexity by 50% and enhance energy savings.
Scenario: A multi-location retail chain needs secure guest Wi-Fi, PoE CCTV cameras and barcode scanners at each store. The WS-C3850-48UW-S-IP Base switch powers cameras, scanners and up to five wireless APs with the bundled licenses. Outcome: Integrated wired/wireless security policies, seamless AP provisioning and high-density UPoE support increase customer engagement by 20% and bolster loss prevention.
When a closet replacement must power high-draw endpoints, the 48-port UPOE chassis limits simultaneous 60W operation to 30 ports with two PWR-C1-1100WAC supplies. Do not equate the powered-port count with full-power concurrency. Specify endpoint priorities and confirm the simultaneous device load before the purchase order.
When extending an existing Catalyst 3850 stack, software feature levels must match, and LAN Base members cannot join an IP Base stack. Cable reach determines whether STACK-T1-50CM=, STACK-T1-1M= or STACK-T1-3M= belongs on the order. Confirm member licensing and physical cable routing before adding hardware to the purchase order.
When staging a legacy converged-access configuration, the wireless-license bundle includes five access point licenses for mobility controller operation. Access point licensing is not needed for mobility agent operation. Confirm the intended controller role, software image, compatible access points and included license entitlement before the purchase order.
Active Cisco hardware support
Cisco support for this discontinued switch ended October 31, 2025. C9300-48U-A is the current replacement for purchases requiring an active hardware lifecycle.
BGP routing without a license upgrade
IP Base does not include BGPv4, IS-ISv4 or full EIGRP. Those protocols require IP Services rather than the included network feature set.
40G uplinks from the module bay
The Gigabit UPOE chassis accepts 1G or 10G network modules, not 40G uplink modules. Expansion through its uplink bay remains limited to 10G interfaces.

WS-C3850-48UW-S identifies a Catalyst 3850 48-port UPOE bundle with five access point licenses and IP Base. WS-C3850 denotes the switch family, 48 the port count, U the UPOE configuration, W the access point license bundle, and S the IP Base feature set.
WS-C3850-48UW-S is managed through the Cisco IOS XE CLI over the console, SSH or Telnet, with Cisco Prime Infrastructure and SNMP monitoring also available. SSH and encrypted SNMPv3 require a cryptographic software image. Configure management access and authentication separately from forwarding and endpoint-power settings.
WS-C3850-48UW-S is discontinued: end-of-sale was October 30, 2020, and Cisco support ended October 31, 2025. C9300-48U-A is the replacement. A reseller purchase does not restart Cisco's lifecycle or restore manufacturer support, so the order must distinguish reseller coverage from Cisco service eligibility.
ORM Systems supplies WS-C3850-48UW-S new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Both conditions have 30-day returns; terms apply. Cisco's Enhanced Limited Lifetime Warranty support ended October 31, 2025. Refurbished units are inspected and bench-tested, with firmware verified and configuration wiped to factory default.
WS-C3850-48UW-S uses perpetual IP Base for standalone switching, without a required Cisco DNA subscription. Optional Cisco DNA Essentials, Cisco DNA Advantage and Cisco DNA Premier paths used minimum three-year terms. Smart Accounts manage add-on entitlements; after expiry, deactivate the add-on and reload to continue with base-license capabilities.
WS-C3850-48UW-S provides an 800W shared PoE budget with one PWR-C1-1100WAC and 1900W with two PWR-C1-1100WAC supplies. Cisco UPOE supports 60W per port, but the dual-supply configuration supports that draw on a maximum of 30 ports simultaneously. Size the endpoint schedule against the shared budget.
WS-C3850-48UW-S accepts C3850-NM-4-1G for four 1G ports, C3850-NM-2-10G for two 10G ports or four 1G ports, and C3850-NM-4-10G for four 10G ports. The base configuration contains no uplink module. Specify one compatible module and its required optics separately; the access-port speed does not change.
Catalyst 3850 StackWise-480 stacks contain nine members with 480 Gbps stack bandwidth. Software feature levels must match, and LAN Base cannot join IP Base. STACK-T1-50CM=, STACK-T1-1M= and STACK-T1-3M= provide cable-reach choices; these are data-stacking cables, not the CAB-SPWR-30CM= or CAB-SPWR-150CM= power-sharing cables.
Catalyst 3850 IP Base supports Static, RIPv1, RIPv2, RIPng, EIGRP Stub, OSPF for routed access and PBR. Full EIGRP, BGPv4, IS-ISv4, VRF-Lite and PIM require IP Services. The 24000 ARP plus learned route figure describes hardware capacity, not permission to use the full routing feature set.
WS-C3850-48UW-S ships with one PWR-C1-1100WAC and an unpopulated second supply bay; redundancy requires an additional supply. A second PWR-C1-1100WAC can increase available endpoint power, but losing a supply also removes that added headroom. Specify the power configuration and simultaneous endpoint load before ordering.
WS-C3850-48UW-S supports 60W Cisco UPOE where WS-C3850-48PW-S supports 30W PoE+; both bundles use IP Base and include five access point licenses. Both are discontinued. The UPOE model serves compatible higher-draw endpoints, while the PoE+ bundle suits devices remaining within the 30W per-port limit.
WS-C3850-48UW-S includes IP Base, whereas WS-C3850-48U-E includes IP Services. Both are discontinued 48-port UPOE models. IP Base covers routed access; IP Services adds full EIGRP, BGPv4 and IS-ISv4. The bundle suits legacy deployments retaining IP Base, while the IP Services variant suits existing installations requiring those advanced protocols.
C9300-48U-A is the current replacement for the discontinued WS-C3850-48UW-S, whose Cisco support ended October 31, 2025. Both provide 48-port UPOE access. Retaining the Catalyst 3850 fits legacy spares or matching existing hardware; the Catalyst 9300 replacement addresses purchases requiring an active hardware lifecycle rather than ended manufacturer support.
