WS-C3750X-12S-E is a managed Layer 3 enterprise access switch with twelve fixed Gigabit SFP ports, an optional uplink module bay and the IP Services feature set. The full-width 1U chassis belongs to the Catalyst 3750-X family and connects fiber Ethernet links rather than supplying endpoint power. Uplink connectivity depends on the module selected; no uplink module is included in the base configuration. The discontinued WS-C3750X-12S-S carries IP Base instead of IP Services on the same twelve-port SFP configuration. For a like-for-like purchase, distinguish the installed software tier from the hardware condition and identify the required uplink configuration separately.
WS-C3750X-12S-E price for new stock is $753.64, a 95.3% saving from the Cisco list price of $16,100.00. WS-C3750X-12S-E refurb price is $204.75. WS-C3750X-12S-E is in stock and available for next-day dispatch. (terms applied)

160 Gbps switching capacity provides the switching fabric for this configuration. 35.7 Mpps forwarding applies with two 10GbE uplinks, so that figure should not be treated as the performance of an unequipped uplink bay. OSPF, EIGRP, BGPv4 and IS-ISv4 provide advanced unicast routing under IP Services, with OSPFv3 and EIGRPv6 available for IPv6. WS-C3750X-12S-E has 512 MB DRAM and 128 MB flash for its control software and local storage. SDM template selection changes the allocation between MAC addresses and routes; their maximum capacities require different templates. The twelve fixed SFP interfaces remain Gigabit interfaces regardless of the uplink module installed.
WS-C3750X-12S-E is offered new sealed or certified refurbished, with ORM coverage of up to a 3-year extended warranty on new units or up to 1 year on refurbished units; both conditions have 30-day returns, terms apply, while Cisco hardware warranty service ended October 31, 2021. Certified refurbished units are inspected and bench-tested for power-on, POST, every port linking at rated speed, clean boot and optics bay recognition, with firmware verified and configuration wiped to factory default. Specify the condition, quantity and required accessories on the purchase order for this switch. POs are accepted, government buyers can use Net-30, and RMA with advance replacement is available across UK, EU, US and MEA regional stock and RMA operations.

In a large enterprise campus connecting 20+ buildings and 5,000+ endpoints, IT deploys Catalyst 3750X 12 Port GE SFP IP Services as the distribution-layer backbone. Twelve 1 Gb SFP fiber uplinks provide low-latency, high-bandwidth transport, while StackWise-Plus delivers 64 Gbps of switch-stack resiliency. Advanced routing (OSPF/EIGRP), SVI-based VLAN segmentation and nonstop forwarding ensure seamless failover, reducing downtime by 70% and future-proofing network growth.
In a mid-sized data center, the Catalyst 3750X 12 Port GE SFP IP Services functions as a leaf switch for server and storage clusters over 1 Gb fiber. Policy-based QoS, PIM-SM multicast and IPv6 support guarantee deterministic performance for virtual machines, backup traffic and live migrations. The result is a 55% improvement in VM migration times, end-to-end application SLAs and simplified multi-protocol routing at the network edge.
A university IT department uses Catalyst 3750X 12 Port GE SFP IP Services to deliver isolated networks for administration, research labs, guest Wi-Fi and IoT devices. Twelve dedicated fiber SFP ports feed each tenant VLAN into VRF-Lite instances, enforcing strict traffic separation without additional hardware. This design boosts security posture, streamlines policy management and accelerates provisioning—cutting service activation times from days to hours.
When replacing a discontinued WS-C3750G-12S-E, WS-C3560E-12SD-E or WS-C3560E-12SD-E=, distinguish a like-for-like legacy purchase from a migration to a newer family. Existing optical links do not settle the complete replacement configuration. Before the PO, verify the uplink arrangement and the accessories included with the offered unit.
When extending an existing power-sharing group, distinguish the power connections from the data-stacking connections. StackPower groups support four switches and use CAB-SPWR-30CM= or CAB-SPWR-150CM=, not data-stacking cables. Before the PO, specify the required cable lengths and confirm the intended power-sharing or redundancy mode.
Switch-supplied power for copper endpoints
WS-C3750X-12S-E has Gigabit SFP access interfaces without PoE output. A requirement to power phones, access points or other endpoints directly from access ports is outside this configuration.
Active Cisco hardware service coverage
Cisco hardware service ended October 31, 2021. C9300-24S is the current migration target, but increases fixed Gigabit SFP density from twelve to twenty-four ports.

WS-C3750X-12S-E identifies a Catalyst 3750-X switch with twelve Gigabit SFP ports and IP Services. WS-C3750X identifies the switch family, 12 identifies the port count, S identifies the SFP configuration and E identifies IP Services. The part number does not identify an installed uplink module.
WS-C3750X-12S-E supports CLI management through console access, Telnet and SSH, together with SNMP, a PC-based configuration tool and CiscoWorks LMS. SSH requires the cryptographic software image. For staging, distinguish local console access from network management access and verify the offered image against the intended administration method.
Yes, WS-C3750X-12S-E reached end of sale on October 30, 2016, and its last date of hardware support was October 31, 2021. Cisco hardware service has ended. Its initial replacement, WS-C3850-12S-E, is also discontinued; the forward migration chain now leads to C9300-24S.
ORM offers WS-C3750X-12S-E new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are 30 days for either condition; terms apply. Cisco's original Enhanced Limited Lifetime Hardware Warranty ended October 31, 2021.
WS-C3750X-12S-E includes IP Services and activates its feature set through a local Cisco IOS license file. For the IP Base twelve-port SFP configuration, C3750X-12S-S-E provides the paper upgrade path and L-C3750X-12S-S-E provides the electronic upgrade path. Those upgrades are separate from purchasing the E-suffix switch.
WS-C3750X-12S-E replaces WS-C3750G-12S-E, WS-C3560E-12SD-E and WS-C3560E-12SD-E=. All three predecessors reached end of sale on January 30, 2013. They are discontinued products, and WS-C3750X-12S-E is now discontinued too. Replacement purchasing therefore needs to distinguish historical compatibility from a current-family migration.
WS-C3750X-24P-E provides PoE+ access ports, while WS-C3750X-12S-E provides unpowered Gigabit SFP access interfaces. Both models are discontinued. The former addresses legacy purchases requiring endpoint power; the latter addresses legacy fiber connections where the switch does not need to supply power to attached equipment.
WS-C3750X-12S-E includes IP Services, while WS-C3750X-12S-S includes IP Base. Both are discontinued twelve-port Gigabit SFP configurations. IP Services provides the advanced routing feature set; IP Base suits legacy installations whose feature requirements remain within that tier. Match the purchased license to the existing configuration requirements.
C9300-24S provides twenty-four fixed Gigabit SFP ports, compared with twelve on WS-C3750X-12S-E. C9300-24S is the current migration target reached through the discontinued WS-C3850-12S-E replacement. The older switch suits exact legacy sparing; the newer configuration suits migration orders that can accommodate the increased port density.
Catalyst 3750-X StackWise Plus stacks nine members and provides 64 Gbps stack throughput. Compatible data-stacking cable options include CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M=. These connections are separate from StackPower connections. Specify cable lengths for the physical stack layout rather than substituting power-sharing cables.
