Cisco WS-C3750X-12S-S 12-Port Gigabit SFP Stackable Switch

Product Description

The Cisco Catalyst WS-C3750X-12S-S is a fixed-configuration enterprise access switch from the Catalyst 3750-X series, featuring 12 Gigabit Ethernet SFP ports with an IP Base software license. Designed for enterprise wiring closets and medium-sized network cores, this switch provides a compact, high-density fiber-optic connectivity solution for aggregating server traffic or linking distribution layers in a campus network.

Technical Specifications

• Model: WS-C3750X-12S-S
• Ports: 12 Gigabit Ethernet SFP (fiber)
• Software License: IP Base
• Series: Catalyst 3750-X
• Form Factor: Fixed-configuration rack-mountable
• Switching Capacity: Stackable via Cisco StackWise Plus (up to 9 units)

Design Features

• All ports are SFP-based, enabling flexible fiber optic connectivity (1000BASE-SX/LX/ZX) for long-distance links.
• StackWise Plus technology allows stacking of multiple units into a single logical switch, simplifying management and scaling.
• Modular power supply and fan tray design for field-replaceable components.
• Supports energy-efficient Ethernet (EEE) and advanced QoS features.
• IP Base license provides static routing, RIP, and basic security policies suitable for Layer 3 edge deployments.

Application Area

The WS-C3750X-12S-S is deployed in enterprise campus networks as an access-layer switch for fiber-based endpoints, such as server farms, storage arrays, or remote wiring closets requiring optical uplinks. It is also used in data center top-of-rack (ToR) configurations for low-latency aggregation of non-PoE devices, or as a distribution switch in small-to-medium network segments where compact SFP density and stacking are prioritized.
