WS-C3750X-48P-E combines 48 Gigabit Ethernet PoE+ access ports with IP Services Layer 3 routing in a 1U enterprise access switch. The Catalyst 3750-X chassis uses a modular uplink bay rather than fixed uplink ports, leaving optical or copper aggregation connections separate from the base hardware order. Cisco IOS provides switching and routed access for user workstations, IP phones, wireless access points, and video devices. The discontinued WS-C3750X-48PF-E sibling increases the single-supply PoE allowance to 800W. This configuration brings endpoint connectivity, power delivery, and advanced routing into the same chassis, while retaining separate purchasing decisions for uplink connectivity and additional power capacity.
WS-C3750X-48P-E price for new stock is $6,294.75, a 74% saving from the Cisco list price of $24,200.00. WS-C3750X-48P-E refurb price is $216.80. WS-C3750X-48P-E is in stock and available for next-day dispatch. (terms applied)

160 Gbps switching capacity handles traffic within the switching fabric. 101.2 Mpps forwarding applies with two 10G uplinks installed, making the selected uplink configuration relevant to performance planning. 435W of shared PoE power requires endpoint allocations within the available total rather than maximum power on every port simultaneously. OSPF, EIGRP, BGPv4, and IS-ISv4 support dynamic IPv4 routing; OSPFv3 and EIGRPv6 extend routing to IPv6. WS-C3750X-48P-E provides 256 MB of DRAM and 64 MB of flash for operating software and local image storage. Cisco Catalyst 3750-X resource allocation depends on the selected switching template: maximum MAC-address capacity and maximum route capacity belong to different templates and are not simultaneous limits. Administrators can separate console access from network management using the dedicated management connection. MACsec protects host-facing links, while uplink encryption requires C3KX-SM-10G. UPOE is not available on this PoE+ model, so higher-power endpoint requirements must be qualified separately.
WS-C3750X-48P-E is offered new sealed or certified refurbished; ORM-certified refurbishment is distinct from Cisco-remanufactured WS-C3750X-48P-E-RF. 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 condition, accessories, and quantities on the PO: new units carry up to a 3-year extended warranty, certified refurbished units up to 1 year, and every condition includes 30-day returns, terms apply; Cisco's enhanced limited lifetime warranty ended October 31, 2021. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement, with regional stock and RMA in the UK, EU, US, and MEA.

In a multi-building enterprise campus, the WS-C3750X-48P-E Catalyst 3750X 48 Port PoE IP Services switch delivers centralized PoE power to IP phones, Wi-Fi access points and surveillance cameras across three floors. Integrated StackWise Plus stacking and Layer 3 IP Services enable simplified management, redundant uplinks and deterministic QoS. Benefit: Streamlined deployment with 740W PoE power budget, sub-second failover, and reduced operational costs through single-pane provisioning.
In a national retail chain rollout, the Catalyst 3750X 48 Port PoE IP Services (WS-C3750X-48P-E) switch powers point-of-sale terminals, RFID scanners and HD IP cameras at each store location. Advanced Layer 3 routing and traffic segmentation isolate payment systems from guest Wi-Fi, while PoE simplifies cabling and reduces installation time. Benefit: Enhanced security compliance (PCI DSS), consistent 802.3at power delivery, and centralized monitoring that drives 30% faster store commissioning.
On a smart factory floor, the WS-C3750X-48P-E Catalyst 3750X switch aggregates hundreds of PoE-powered IoT sensors, machine-vision cameras and barcode readers. IP Services features—OSPF, ACLs and NetFlow—enforce secure device segmentation and real-time analytics at the edge. Benefit: Increased operational uptime with sub-millisecond convergence, proactive fault isolation and simplified firmware management, resulting in a 20% boost in production efficiency.
When an existing power-sharing installation needs another switch, StackPower groups contain four switches and use power interconnects separate from data-stacking connections. CAB-SPWR-30CM= and CAB-SPWR-150CM= provide different connection lengths. Identify group membership, cable reach, and the intended power-sharing or redundancy mode before specifying the interconnects on the PO.
When separate routed networks must retain overlapping IP addresses, IP Services supports VRF-Lite rather than requiring a single shared routing context. The configuration must preserve the intended separation between those networks. Confirm the required routing instances, interface assignments, and installed license entitlement before specifying the replacement hardware on the PO.
When maintenance inventory requires component-level spares, C3KX-FAN-23CFM= is the cooling spare for this chassis. Keep switch quantities and cooling-spare quantities separate rather than assuming that a replacement switch order includes additional spare components. Identify regional power-cord requirements, then confirm the accessory quantities and required hardware condition before issuing the PO.
Native multigigabit endpoint connections
WS-C3750X-48P-E provides fixed access connections at 1GbE maximum. Faster optional modules add uplink connectivity only; they do not increase the native speed of the copper access ports.
60W power for individual endpoints
WS-C3750X-48P-E supports PoE+ at 30W per port, not 60W UPOE. An endpoint requiring 60W cannot receive its requested power from this model.
Active Cisco service contract coverage
Cisco service for WS-C3750X-48P-E ended October 31, 2021. The direct WS-C3850-48P-E replacement is also discontinued; C9300-48P-A is the current 48-port PoE+ migration choice.

WS-C3750X-48P-E identifies a stackable Catalyst 3750-X switch: WS-C3750X identifies the switch family, 48 identifies the access-port count, P identifies PoE+ ports, and E identifies IP Services. The configuration includes Gigabit copper access connections and C3KX-PWR-715WAC, while the uplink module is a separate ordering choice.
WS-C3750X-48P-E is managed through web-based Device Manager, Cisco IOS CLI over console, SSH or Telnet, Cisco Network Assistant, CiscoWorks LMS, and SNMP applications. SSH and SNMPv3 require a cryptographic software image. Select the management path and verify the installed image before configuring administrator access.
435W is the shared PoE allowance for WS-C3750X-48P-E with its standard C3KX-PWR-715WAC. Individual ports support 30W PoE+, but the allowance does not support every port at that maximum simultaneously. A full-port PoE+ configuration requires C3KX-PWR-1100WAC plus C3KX-PWR-715WAC, or two C3KX-PWR-1100WAC supplies.
WS-C3750X-48P-E accepts C3KX-NM-1G, C3KX-NM-10G, C3KX-NM-10GT, or C3KX-SM-10G; no uplink module is included by default. C3KX-NM-1G supplies four Gigabit connections, C3KX-NM-10G supports two 10G optical connections, and C3KX-NM-10GT supplies two 10G copper connections. C3KX-SM-10G adds service functionality with two 10G optical connections.
StackWise Plus connects nine Catalyst 3750-X switches as one logical switching unit with 64 Gbps stack throughput. CAB-STACK-50CM=, CAB-STACK-1M=, and CAB-STACK-3M= provide data-stacking connections. LAN Base members cannot join a mixed stack with IP Base or IP Services members, so verify each member's feature set before expansion.
Yes, WS-C3750X-48P-E includes IP Services for full OSPF, EIGRP, BGPv4, and IS-ISv4, plus OSPFv3 and EIGRPv6 for IPv6. PBR and multicast routing are also supported. Route capacity depends on the selected switching template, so the routing allocation must match the intended configuration rather than assuming every resource maximum simultaneously.
No, WS-C3750X-48P-E ships with one C3KX-PWR-715WAC and leaves the second power-supply position available for an additional supply. Redundancy is therefore optional rather than included in the base order. Specify the second supply separately and verify both endpoint-power requirements and the intended behavior following a supply failure.
Catalyst 3750-X uses Cisco IOS feature-set licenses named LAN Base, IP Base, and IP Services; WS-C3750X-48P-E includes IP Services. Lower-tier configurations have factory, paper-license, and electronic-license upgrade paths. Permanent licensing has no subscription term, while temporary licensing is distinct from the purchased permanent entitlement and must not be treated as equivalent.
WS-C3750X-48P-E replaced WS-C3750E-48PD-E and WS-C3750G-48PS-E, both of which reached end of sale on January 30, 2013. Those predecessor relationships identify the historical migration path, not current support availability. WS-C3750X-48P-E has also ended Cisco support, and its forward migration chain now reaches C9300-48P-A.
WS-C3750X-48P-E is discontinued: end of sale was October 30, 2016, and Cisco support ended October 31, 2021. Its direct replacement, WS-C3850-48P-E, is also discontinued and ended support on October 31, 2025. The forward migration chain reaches C9300-48P-A, rather than stopping at the discontinued intermediate model.
ORM offers WS-C3750X-48P-E new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year. Both conditions include 30-day returns; terms apply. Cisco's enhanced limited lifetime hardware warranty ended October 31, 2021. Certified refurbished units are inspected and bench-tested, with firmware verified and configuration wiped to factory default.
WS-C3750X-48PF-E provides an 800W single-supply PoE allowance, compared with 435W for WS-C3750X-48P-E. Both are discontinued Gigabit PoE+ configurations with IP Services. The PF variant fits a legacy endpoint plan requiring more supplied PoE capacity; the P variant fits a legacy plan whose allocations stay within the smaller allowance.
WS-C3750X-48P-E includes IP Services, while WS-C3750X-48P-S includes IP Base; both configurations are discontinued. IP Services enables full OSPF, EIGRP, BGPv4, and IS-ISv4 rather than the baseline routing feature set. The E variant fits legacy orders requiring advanced routing, while the S variant fits baseline routed-access requirements.
WS-C3750X-48P-E has ended Cisco support, while C9300-48P-A is the current endpoint of its replacement chain. That chain passes through the discontinued WS-C3850-48P-E rather than making C9300-48P-A the original direct replacement. WS-C3750X-48P-E fits legacy hardware continuity; C9300-48P-A fits purchasing requirements for a current 48-port PoE+ migration model.
134.9W is a measured no-PoE-load consumption figure for WS-C3750X-48P-E with C3KX-NM-1G installed and no traffic; it is not a maximum with powered endpoints. Uplink-module selection changes measured consumption. Size electrical and UPS capacity for the actual hardware configuration and endpoint load, rather than treating the PoE allowance as input draw.
