WS-C3750X-48PF-S is a managed Layer 3 access switch with 48 Gigabit Ethernet PoE+ ports and the IP Base feature set. Its rack-mount 1U chassis has a modular uplink bay rather than fixed fiber uplinks; an uplink network module is not included in the base configuration. The Catalyst 3750-X Series supports enterprise access connections for IP phones, wireless access points and other Ethernet endpoints. This full-PoE variant includes C3KX-PWR-1100WAC. The discontinued WS-C3750X-48P-S sibling has a lower default PoE allocation, making the powered-device inventory an important distinction when matching replacement hardware to an existing installation.
WS-C3750X-48PF-S price for new stock is $1,480.50, a 90.8% saving from the Cisco list price of $16,100.00. WS-C3750X-48PF-S refurb price is $110.88. WS-C3750X-48PF-S is in stock and available for next-day dispatch. (terms applied)

160 Gbps switching capacity supports the switch fabric. 101.2 Mpps forwarding applies with two 10GbE uplinks installed, not an empty uplink bay. IP Base supports Static, RIPv1, RIPv2, RIPng and EIGRP Stub routing. OSPF routed access has a combined planning limit of 1000 dynamically learned OSPFv2 and OSPFv3 routes on Cisco IOS 15.2(4)E; those restrictions are not software-enforced in that release. Full BGPv4, EIGRP and IS-ISv4 require IP Services. WS-C3750X-48PF-S carries 256 MB DRAM and 64 MB flash memory. SDM templates allocate forwarding resources differently: maximum MAC-address capacity and maximum route capacity are not simultaneous settings. RSTP, MSTP and LACP support loop control and link aggregation, while IP Base includes MACsec support.
WS-C3750X-48PF-S 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; returns are available for 30 days on every condition, terms apply. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot and PoE output under load on every powered port, with firmware verified and configuration wiped to factory default. Specify the condition, quantity and required accessories on the purchase order. Enterprise and volume POs are accepted, government orders have Net-30 terms, and RMA includes advance replacement.

In a 5-building corporate campus, IT teams deploy the Catalyst 3750X 48 Port Full PoE IP Base (WS-C3750X-48PF-S) to power 200+ IP phones and 60 Wi-Fi access points. With 740W PoE+ budget, stacking up to nine switches, and Layer 3 routing, the solution delivers consistent voice quality, seamless mobility, and simplified management. Benefit: streamlined device provisioning, predictable network performance, and reduced operational overhead for uninterrupted unified communications.
A multi-campus hospital leverages WS-C3750X-48PF-S switches to support 48 PoE cameras per rack in critical zones (ER, ICU, entrances). The switch’s full PoE+ capability, advanced QoS prioritization, and IP Base security features enable real-time HD video streaming and rapid forensic retrieval. Benefit: enhanced patient safety and compliance through reliable, high-availability surveillance with centralized monitoring and minimal downtime.
A 30-floor commercial tower implements Catalyst 3750X 48 Port Full PoE IP Base switches at each floor to power IoT sensors, smart lighting controllers, and environmental monitors. Integrated Layer 3 routing, Cisco StackWise Plus, and policy-based access control ensure secure segmentation and scalable device roll-outs. Benefit: optimized energy consumption, reduced utility costs, and future-proofed network architecture for next-generation smart building applications.
When an existing stack needs another member, verify its software feature sets before allocating the new position. LAN Base members cannot mix with IP Base or IP Services in a Catalyst 3750-X stack. Specify CAB-STACK-1M= where the inter-switch spacing requires that cable.
When a wiring closet is moving from switched uplinks to routed links, use a stub or totally stub OSPF area and let distribution supply a default route. The access design should not require the complete upstream routing table. Specify the intended OSPF topology before the PO.
When a retained switch estate needs replacement reserves, define quantities for each destination rather than combining all sites into one allocation. Regional stock and RMA cover the UK, EU, US and MEA. Specify the destination region and reserve quantity on each PO.
Active Cisco service coverage
Cisco service ended October 31, 2021, and the direct replacement is also discontinued. C9300-48P-A is the current 48-port PoE+ successor for a supported hardware purchase.
Endpoints requiring more than 30W
Each powered port supplies at most 30W, so endpoints needing higher input power cannot receive it from this switch. Additional PSU capacity does not increase that per-port limit.
Full BGPv4 routing under IP Base
IP Base excludes full BGPv4, EIGRP and IS-ISv4; these require IP Services. The supplied license therefore does not cover those advanced enterprise unicast routing functions.

WS-C3750X-48PF-S identifies a Catalyst 3750-X switch: WS-C3750X is the family prefix, 48 denotes the Gigabit Ethernet port count, PF identifies the full-PoE hardware variant, and S selects IP Base. The configuration includes C3KX-PWR-1100WAC but does not include an uplink network module.
WS-C3750X-48PF-S supports Device Manager web access, CLI through USB or RJ-45 console connections, remote SSH or Telnet, Cisco Network Assistant and SNMP management. CiscoWorks LMS provides networkwide management, while the Cisco IE2100 Configuration Registrar supports configuration automation. SSH requires the appropriate cryptographic software image.
WS-C3750X-48PF-S is discontinued: Cisco ended sales on October 30, 2016, and support on October 31, 2021. Its direct replacement, WS-C3850-48F-S, is also discontinued and reached its last support date on October 31, 2025. The forward replacement chain ends at current C9300-48P-A.
ORM offers WS-C3750X-48PF-S new sealed with up to 3-year extended warranty, or certified refurbished with up to 1 year. Both conditions have 30-day returns; terms apply. Cisco's original Enhanced Limited Lifetime Hardware Warranty ended October 31, 2021. Refurbished units are inspected and bench-tested, with firmware verified and configuration wiped to factory default.
WS-C3750X-48PF-S uses permanent IP Base licensing, with IP Services available through software activation when the corresponding entitlement is present. Permanent licenses have no subscription renewal term; universal images also support temporary licenses. A used hardware purchase does not establish software transfer rights, so confirm the entitlement before ordering.
WS-C3750X-48PF-S replaces WS-C3750E-48PD-SF, which reached end of sale on January 30, 2013. The older configuration included two 10GE X2 uplinks, whereas the replacement uses optional uplink modules. Preserve the existing link requirements by specifying C3KX-NM-10G and compatible optics rather than ordering only the replacement chassis.
WS-C3750X-48PF-S provides an 800W shared PoE budget with its supplied C3KX-PWR-1100WAC, and each powered port supports up to 30W. That single-supply budget does not cover 30W on all 48 ports simultaneously. Adding C3KX-PWR-1100WAC= as the second supply supports full PoE+ power across every port.
No, WS-C3750X-48PF-S ships without an uplink network module. C3KX-NM-10G provides two 10GbE SFP+ connections, C3KX-NM-10GT provides two 10GBASE-T connections, and C3KX-SM-10G provides two 10GbE SFP+ service-module connections. C3KX-NM-1G instead provides four Gigabit uplinks. Specify the module and matching optical components for the intended connection.
StackWise Plus connects nine Catalyst 3750-X members and provides 64 Gbps stacking bandwidth. Dedicated rear connectors carry the stack links, separately from access ports and uplink modules. Cable choices include CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M=; select lengths that match the intended rack spacing and stack cabling layout.
142.9W is the Catalyst 3750-X 48PF consumption figure with C3KX-NM-10G installed, 100% traffic and no PoE endpoint load. The test uses 115V AC at 60 Hz. That measurement is not the complete draw of a powered deployment, so endpoint loading must be considered separately when sizing electrical capacity.
Yes, WS-C3750X-48PF-S supports OSPF for routed access with IP Base. On Cisco IOS 15.2(4)E, one OSPFv2 instance and one OSPFv3 instance share a 1000 dynamically learned-route planning limit, although that release does not enforce the restriction. IP Services is required for unrestricted multiple instances and broader enterprise routing.
WS-C3750X-48PF-S provides an 800W default PoE budget, while WS-C3750X-48P-S provides 435W. Both are discontinued 48-port PoE+ IP Base configurations. The PF model suits retained installations with larger powered-device allocations; the lower-budget P model suits existing deployments whose endpoint inventory does not require that additional power allocation.
WS-C3750X-48PF-S carries IP Base, while WS-C3750X-48PF-E carries IP Services; both hardware configurations are discontinued. IP Services enables full EIGRP, BGPv4 and IS-ISv4 beyond the supplied IP Base feature set. IP Base fits retained routed-access configurations; deployments requiring those advanced protocols need the corresponding IP Services software rights.
WS-C3750X-48PF-S is beyond Cisco support, while C9300-48P-A is the current successor reached through the discontinued WS-C3850-48F-S replacement. Both retain 48 Gigabit PoE+ access ports, but they belong to different hardware generations. The older model serves retained-estate replacement needs; C9300-48P-A fits procurement requiring a current supported switch.
