WS-C3850-48P-E combines Layer 3 enterprise access switching with 48 fixed 10/100/1000Mbps RJ-45 PoE+ ports in a Rack-Mount 1U chassis. The uplink architecture is modular, with an empty bay rather than factory-installed fiber uplinks; permitted choices provide 1G or 10G connectivity. IP Services is the as-shipped software tier for this Catalyst 3850 configuration, serving powered access devices alongside ordinary Ethernet endpoints. The 48-port Gigabit PoE+ access switch fits an existing campus access design where hardware and software consistency determine the purchase. The discontinued WS-C3850-48F-E differs by providing an 800W single-supply PoE budget. Cisco service for the requested model has ended, so procurement should distinguish matching legacy hardware from selecting a supported successor.
WS-C3850-48P-E price for new stock is $2,814.00. WS-C3850-48P-E refurb price is $183.75. WS-C3850-48P-E is in stock and available for free next-day delivery. (terms applied)

176 Gbps switching capacity defines standalone switching throughput, while 130.95 Mpps is the rated forwarding rate with C3850-NM-4-10G providing four 10G uplinks. 435W of shared PoE power is available from the standard PWR-C1-715WAC; endpoint allocations must stay within the installed supply configuration rather than assuming every powered port can deliver its maximum simultaneously. Full OSPF, EIGRP, BGPv4, and IS-ISv4 support routed access, while OSPFv3 and EIGRPv6 handle IPv6 and PIM-SM supports multicast routing. WS-C3850-48P-E carries 4 GB of DRAM and 2 GB of flash for its Cisco IOS XE operating environment. The UADP ASIC underpins hardware forwarding, with 32000 MAC entries and an IPv4 total of 24000 entries covering ARP plus learned routes. Three C3850-FAN-T1= fans provide chassis cooling, and a second internal power-supply bay allows an optional redundant configuration. Management supports local and remote administration; the fixed access ports do not support multigigabit endpoint speeds.
WS-C3850-48P-E is offered new sealed or certified refurbished; ORM provides new units with up to a 3-year extended warranty, certified refurbished units with up to 1 year, and 30-day returns on every condition, terms apply. 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 configuration wiped to factory default. Specify condition, quantity, and required 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 accounts receive Net-30, and RMA includes advance replacement, with regional stock and RMA in the UK, EU, US, and MEA.

A national retail chain rolls out Cisco Catalyst 3850 48 Port PoE IP Services switches in 150 stores to drive point-of-sale terminals, RFID readers and HD security cameras from a single device. The WS-C3850-48P-E’s PoE+ budget and Cisco DNA Center integration streamline remote provisioning, cut cabling costs by 25% and boost store security analytics in real time.
When departments or tenants reuse address ranges, VRF-Lite provides separate routing instances without requiring unique addressing across every network. The IP Services configuration supports VRF-Lite for this separation. Before the PO, check the required routing instances, interface assignments, and existing configuration against the intended network boundaries.
When several sites need the same traffic-monitoring approach, Flexible NetFlow provides 48000 flow entries on the 48-port Gigabit configuration. A shared monitoring plan requires consistent collection and device configuration across the installed estate. Before ordering, specify the collector integration, configuration requirements, and traffic-monitoring settings to standardize.
When equipment will be staged in a cold room before installation, startup temperature matters separately from the normal operating range. The minimum ambient temperature for a cold start is 0°C. Include the staging environment in the acceptance plan, and check startup conditions before specifying the batch on the PO.
Cisco support for production deployments
WS-C3850-48P-E passed its last date of support on October 31, 2025. C9300-48P-A is the current replacement for projects requiring a supported successor rather than discontinued hardware.
Forty-gigabit uplinks on this chassis
WS-C3850-48P-E accepts C3850-NM-4-1G, C3850-NM-2-10G, and C3850-NM-4-10G; uplinks top out at 10G, not 40G. C3850-NM-2-40G is incompatible with this hardware configuration and cannot provide a 40G upgrade.
Multigigabit connections for wireless access points
WS-C3850-48P-E fixed access ports operate at 10/100/1000Mbps, so 2.5G and 5G endpoint links are not supported. Changing the uplink module cannot increase the RJ-45 access-port speeds.

Reliable PoE and routing combination.
WS-C3850-48P-E identifies a Catalyst 3850 with 48 Gigabit Ethernet PoE+ ports and IP Services. WS-C3850 identifies the switch family, 48 identifies the port count, P identifies PoE+, and E identifies IP Services. The configuration includes PWR-C1-715WAC and a separately populated uplink bay.
WS-C3850-48P-E provides a 435W shared PoE budget with the supplied PWR-C1-715WAC, and each PoE+ port supports 30W. The budget does not allow all 48 ports at maximum simultaneously. Adding PWR-C1-1100WAC increases available PoE power to 1535W; endpoint allocations must remain within the installed configuration's budget.
WS-C3850-48P-E accepts C3850-NM-4-1G, C3850-NM-2-10G, and C3850-NM-4-10G, with no uplink module installed in the base configuration. These provide four 1G, two 10G, or four 10G uplinks respectively. Order the selected module and compatible optics separately; the fixed copper access ports remain Gigabit Ethernet.
WS-C3850-48P-E does not require a Cisco DNA subscription for base IP Services operation. Historical Cisco DNA Essentials, Cisco DNA Advantage, and Cisco DNA Premier add-ons started at three years and used Smart Account management. Add-on expiration leaves the perpetual base license intact; deactivation requires a reload to resume base-only operation.
Catalyst 3850 supports a web UI, console CLI, SSH, Telnet, SNMP, Cisco Prime Infrastructure, and license-dependent Cisco DNA Center management. SSH and encrypted SNMPv3 require a cryptographic software image. Specify the intended management method and software entitlement before deployment; centralized management does not eliminate local CLI access.
WS-C3850-48P-E supports full OSPF, EIGRP, BGPv4, and IS-ISv4 with IP Services, plus OSPFv3 and EIGRPv6 for IPv6 routing. PIM-SM and PIM-DM support multicast routing. The 24000-entry IPv4 total includes ARP and learned routes; this is not a separate allowance of 24000 dynamic routes in addition to neighbor entries.
No, WS-C3850-48P-E ships with one PWR-C1-715WAC and a second internal power-supply bay available for an optional supply. Redundancy is not populated as standard. An additional PWR-C1-1100WAC can increase PoE power; specify the second supply explicitly and distinguish power sharing from redundancy when sizing endpoint loads.
WS-C3850-48P-E supports nine-member Catalyst 3850 stacks using StackWise-480 at 480 Gbps throughput. Specify STACK-T1-50CM=, STACK-T1-1M=, or STACK-T1-3M= for the required reach. StackPower uses CAB-SPWR-30CM= or CAB-SPWR-150CM= instead and normally groups four members; matching software feature sets is also required when assembling the data stack.
Yes, the 48-port Catalyst 3850 configuration is a full-width Rack-Mount 1U chassis measuring 44.5 mm high, 445 mm wide, and 450 mm deep. WS-C3850-48P-E weighs 7.9 kg with one supply and without an uplink module. Confirm C3850-RAC-KIT= mounting hardware on the order and check cabinet depth before purchase.
WS-C3850-48P-E replaces WS-C3750X-48P-E, which reached end of sale on October 30, 2016. Both identifiers describe 48-port PoE configurations with IP Services, but they belong to different switch generations. Both models are now discontinued; purchasing a matching legacy spare is different from selecting a current Cisco-supported replacement.
WS-C3850-48P-E is discontinued: end of sale was October 30, 2020, and Cisco's last date of support was October 31, 2025. Cisco service has ended for this part number. C9300-48P-A is the named replacement; hardware condition does not restart Cisco's lifecycle clock or restore ended support.
WS-C3850-48F-E has an 800W single-supply PoE budget, compared with 435W on WS-C3850-48P-E. Both are 48-port Gigabit PoE+ IP Services models, but WS-C3850-48F-E ships with PWR-C1-1100WAC instead of PWR-C1-715WAC. Both are discontinued; buyers matching legacy hardware should select according to endpoint power allocation rather than port count.
WS-C3850-48P-E includes IP Services, while WS-C3850-48P-S includes IP Base. IP Services enables full OSPF, EIGRP, BGPv4, and IS-ISv4; IP Base provides a more limited routing feature set. Both are discontinued. The E configuration suits legacy spares requiring advanced routing; the S configuration suits installations standardized on IP Base.
C9300-48P-A is the current successor, while WS-C3850-48P-E passed Cisco's last date of support on October 31, 2025. Both are 48-port PoE+ switches. C9300-48P-A suits a supported refresh; the discontinued WS-C3850-48P-E suits legacy hardware matching only when ended Cisco service is acceptable for the intended installation.
ORM offers WS-C3850-48P-E new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year; both have 30-day returns, terms apply. Refurbished units are inspected and bench-tested. Cisco's original Enhanced Limited Lifetime Warranty ended with Cisco support on October 31, 2025; ORM's order warranty is separate.
