Campus PoE+ Access for Wiring Closets

WS-C3850-48P-S is a 48-port Gigabit PoE+ managed Layer 3 access switch with an empty modular uplink bay and IP Base licensing. The Catalyst 3850 chassis serves campus and branch wiring closets that need 10/100/1000 copper access, endpoint power and stackable operation in a 1U rack profile. Its bay accepts C3850-NM-4-1G, C3850-NM-2-10G or C3850-NM-4-10G, so SFP or SFP+ uplinks are specified separately rather than assumed in the base unit. StackWise-480 stacks nine members, and StackPower can pool power across four members using CAB-SPWR-30CM or CAB-SPWR-150CM. The Cisco Catalyst 3850 Series keeps a modular access design, while WS-C3850-48F-S moves the same 48-port PoE+ access profile to an 1100WAC supply and 800W PoE budget.

WS-C3850-48P-S price for new stock is $985.95, a 92.4% saving from the Cisco list price of $13,000.00. WS-C3850-48P-S refurb price is $152.25. WS-C3850-48P-S is in stock and available for next-day dispatch. (terms applied)

Technical Details

176 Gbps switching capacity supports the 48-port Gigabit access profile, and 130.95 Mpps forwarding applies with four 10 Gigabit uplinks installed. 435W PoE budget is shared across the powered ports with the shipped PWR-C1-715WAC; all-port 30W PoE+ requires a higher dual-supply combination. WS-C3850-48P-S runs IP Base with static routing, RIPv1, RIPv2, RIPng, EIGRP Stub, OSPF for routed access and PBR, while full OSPF, EIGRP, BGPv4, IS-ISv4 and PIM require IP Services. UADP forwarding silicon, 4 GB DRAM, 2 GB flash, 32000 MAC addresses and 24000 IPv4 routes set the scale. Management is through the console, CLI over SSH or Telnet and SNMPv3, with StackWise-480 presenting a stack as one unit.

Ordering

Order WS-C3850-48P-S new sealed or certified refurbished, and add the uplink module, optics, StackWise-480 cables and any second power supply to the same PO. Refurbished managed units are inspected and bench-tested; checks include power-on and POST, every access port linking at rated speed, PoE output verified under load, module bay recognition, StackWise adapter negotiation, PSU status, fan status, firmware verification and configuration wipe to factory default. New units qualify for up to a 3-year extended warranty, certified refurbished units qualify for up to 1 year, and every condition has 30-day returns, terms apply. PO accepted, Net-30 is available for government, RMA includes advance replacement, and regional stock or RMA coverage spans UK, EU, US and MEA.

WS-C3850-48P-S Use Case

Access Closet Endpoint Handoff

WS-C3850-48P-S sits at the campus access layer and terminates copper runs from phones, workstations, cameras, printers, and wireless access points on 48 10/100/1000 RJ-45 PoE+ ports. Engineers assign VLANs, QoS markings, authentication policy, and per-port PoE controls close to the endpoint, then send northbound traffic through the selected Catalyst 3850 network module. The IP Base image places routed access services in the closet. The network gains powered endpoint density with local policy enforcement and predictable distribution handoffs from every access port.

Stacked Access Block Expansion

Multiple compatible IP Base Catalyst 3850 switches form a StackWise-480 access block when a closet needs more powered Gigabit ports under one operational plane. WS-C3850-48P-S contributes 48 PoE+ ports per member, participates in StackPower designs with the required cables, and presents unified CLI and management addressing across the stack. Engineers standardize software levels, stack numbering, uplink modules, and power budgets before adding members. Operations teams troubleshoot one logical access block instead of separate switches, and the closet gains controlled port-density expansion.

Branch Wired-Wireless Policy Point

WS-C3850-48P-S operates in a branch access role where local copper endpoints and Cisco wireless access points land on the same Catalyst platform. The switch delivers PoE+ to access points and phones, applies IOS XE access policies, and supports Catalyst 3850 wireless mobility agent functions included with IP Base. Traffic leaves the branch through the chosen 1G or 10G network module toward WAN or distribution equipment. The site gains a single access policy point for wired and wireless traffic with local powered endpoint handoff.

Best For

PoE Closet Sizing

An access closet with IP phones, access points and cameras can standardize on 48 PoE+ copper ports, but 435W is a shared budget with PWR-C1-715WAC. Total the endpoint draw, then add the documented higher power-supply combination if the PO must cover all-port 30W PoE+.

Stack Extension

An existing Catalyst 3850 IP Base stack can add this model when software feature sets match across members. StackWise-480 supports nine members, while StackPower supports four members with separate CAB-SPWR-30CM or CAB-SPWR-150CM cables, so specify stack and power cables with the chassis.

Uplink Staging

A refresh that keeps 1G access ports but changes distribution speed can stage the uplink decision separately from the chassis. Choose C3850-NM-4-1G, C3850-NM-2-10G or C3850-NM-4-10G before the PO, then source the matching SFP or SFP+ optics.

Not Suitable If

UPOE endpoints

WS-C3850-48P-S is PoE+ at 30W per port, not Cisco UPOE at 60W; C9300-48U-A is the named current successor for 48-port UPOE IP Base.

Mixed license stacks

IP Base Catalyst 3850 members cannot stack with LAN Base or IP Services members; match IP Base or add C3850-48-S-E / L-C3850-48-S-E before stacking.

All-port PoE+ from one supply

The shipped PWR-C1-715WAC provides 435W, not 1440W; specify two PWR-C1-1100WAC or one PWR-C1-1100WAC with one PWR-C1-715WAC.

Questions & Answers

What does WS-C3850-48P-S mean?

WS-C3850-48P-S identifies a Catalyst 3850 switch with 48 10/100/1000 Ethernet PoE+ ports, a 715WAC power supply and the IP Base feature set. The WS-C3850 segment is the platform family, 48P maps to the 48-port PoE+ access configuration, and S maps to IP Base.

How is WS-C3850-48P-S managed?

WS-C3850-48P-S is managed through the console, CLI over SSH or Telnet and SNMPv3. StackWise-480 can present a stack through one management IP address and one CLI session, while the Ethernet management port uses an RJ-45 connection separate from the access ports.

Is WS-C3850-48P-S end-of-sale?

WS-C3850-48P-S is end-of-sale and past Cisco support. End-of-sale was 30 October 2020, and the last date of support was 31 October 2025. C9300-48P-A is the named replacement, so lifecycle-sensitive orders should treat this as a discontinued Catalyst 3850 hardware PID.

What condition and warranty does ORM offer for WS-C3850-48P-S?

WS-C3850-48P-S is offered new sealed or certified refurbished. Cisco E-LLW service ended on 31 October 2025; ORM offers 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.

What license does WS-C3850-48P-S use?

WS-C3850-48P-S ships with IP Base as the perpetual feature set. IP Base includes routed access features, while C3850-48-S-E or L-C3850-48-S-E upgrades a 48-port IP Base switch to IP Services RTU. Cisco DNA Essentials and Cisco DNA Advantage 48-port add-on terms start at 3 years.

Which older PID did WS-C3850-48P-S replace?

WS-C3850-48P-S is named as the replacement for WS-C3750X-48P-S. The older model was a Catalyst 3750X 48 Port PoE IP Base switch, while the Catalyst 3850 replacement keeps the 48-port PoE IP Base role and moves into the StackWise-480 generation.

How many PoE+ ports does WS-C3850-48P-S have?

WS-C3850-48P-S has 48 10/100/1000 PoE+ access ports with a 435W PoE budget on the shipped PWR-C1-715WAC. PoE+ can provide 30W per port, but all 48 ports at 30W require two PWR-C1-1100WAC supplies or one PWR-C1-1100WAC with one PWR-C1-715WAC.

Which uplink modules work with WS-C3850-48P-S?

WS-C3850-48P-S supports C3850-NM-4-1G, C3850-NM-2-10G and C3850-NM-4-10G in its modular uplink bay. The base switch does not include a network module, so the module and the required SFP or SFP+ optics must be specified separately.

Can WS-C3850-48P-S stack with other Catalyst 3850 switches?

WS-C3850-48P-S can stack through StackWise-480, which supports nine Catalyst 3850 members and 480 Gbps stacking bandwidth. Catalyst 3850 stacks must match software feature sets, so an IP Base member is not supported in a mixed LAN Base or IP Services stack.

What routing protocols does Catalyst 3850 IP Base support?

Catalyst 3850 IP Base supports static routing, RIPv1, RIPv2, RIPng, EIGRP Stub, OSPF for routed access and PBR. Full OSPF, EIGRP, BGPv4, IS-ISv4, VRF-Lite and PIM require IP Services rather than the IP Base feature set on this SKU.

What is the difference between WS-C3850-48P-S and WS-C3850-48F-S?

WS-C3850-48F-S ships with an 1100WAC supply and 800W PoE budget where WS-C3850-48P-S ships with PWR-C1-715WAC and a 435W PoE budget. Both are 48-port PoE+ IP Base models, so choose WS-C3850-48F-S for higher PoE headroom and WS-C3850-48P-S for matching the 715WAC tier.

What is the difference between WS-C3850-48P-S and WS-C3850-48P-E?

WS-C3850-48P-E carries IP Services where WS-C3850-48P-S carries IP Base. The hardware description stays aligned at 48 10/100/1000 Ethernet PoE+ ports with a 715WAC supply, so WS-C3850-48P-E suits full enterprise Layer 3 routing and WS-C3850-48P-S suits IP Base routed access.

What is the difference between WS-C3850-48P-S and C9300-48P-A?

C9300-48P-A is the named replacement for WS-C3850-48P-S. The replacement is a Catalyst 9300 48-port PoE+ switch with Network Advantage, while WS-C3850-48P-S is a discontinued Catalyst 3850 IP Base model suited to existing 3850 stacks and spare pools.

Does WS-C3850-48P-S need a second power supply?

WS-C3850-48P-S ships with one PWR-C1-715WAC, and the second internal power-supply bay is optional. A second supply can be added for redundancy or higher PoE capacity, but all-port 30W PoE+ specifically requires the documented PWR-C1-1100WAC combinations.
