Cisco WS-C3750X-24P-SCisco Catalyst WS-C3750X-24P-S 24 Port Gigabit PoE+ Switch

Cisco Catalyst WS-C3750X-24P-S Certified Refurbished Layer 3 Managed Switch

The Cisco Catalyst WS-C3750X-24P-S features 24 Gigabit Ethernet ports with 802.3at PoE+ delivering up to 435W power budget, 256MB DRAM, 128MB flash memory, StackWise Plus technology supporting up to 9-unit stacks with 64Gbps throughput, and IP Base software for enterprise-class Layer 3 switching. This certified refurbished stackable switch provides robust network infrastructure for businesses requiring reliable, scalable connectivity with advanced features including hardware-based MACsec encryption, flexible expansion options, and comprehensive management capabilities.

Enterprise-Class Performance and Connectivity

This 1RU rack-mountable switch delivers wire-speed Gigabit performance across all 24 10/100/1000 Ethernet ports, each supporting IEEE 802.3at PoE+ with up to 30W per port. The integrated expansion slot accommodates four optional network module types, including dual 10GbE SFP+ uplinks for high-bandwidth connections to core infrastructure. StackWise Plus technology enables up to nine switches to operate as a single logical unit, providing 432 total Ethernet ports with 18 10GbE uplinks when fully configured. The dedicated out-of-band management port and dual USB interfaces (Type-A for storage, Type-B for console) simplify deployment and ongoing administration.

Power and Flexibility for Modern Networks

With the included 715W AC power supply, the switch provides 435W of available PoE+ power to support IP phones, wireless access points, surveillance cameras, and other powered devices. Dual redundant modular power supplies and fans ensure high availability, while optional StackPower enables power sharing among stack members for enhanced resilience. The IP Base feature set includes support for 1,000 VLANs, OSPF routing, and comprehensive Layer 3 capabilities, with upgrade paths to IP Services licensing for advanced routing protocols. EnergyWise technology provides intelligent power monitoring and management to reduce operational costs.

Advanced Security and Management

Hardware-based MACsec (IEEE 802.1AE) encryption on all downlink ports protects sensitive data transmissions, while comprehensive authentication options including 802.1X, RADIUS, TACACS+, and Kerberos secure network access. Port security, DHCP snooping, Dynamic ARP Inspection, and IP Source Guard provide multi-layered defence against common network threats. Cisco Smart Operations features including Smart Install, Auto Smartports, and Smart Configuration streamline deployment and reduce configuration errors, while SNMP, RMON, CLI, and web-based management interfaces offer flexible administration options.

Cisco IOS Operating System

Cisco IOS provides industry-leading routing and switching capabilities with precise control over network behaviour, supporting both static and dynamic routing protocols including OSPF, EIGRP, and BGP. The command-line interface offers deep customisation for routing policies, security parameters, and interface configurations, enabling optimisation based on specific business requirements. However, the complexity of IOS requires proper training and expertise, with a steeper learning curve compared to simplified graphical interfaces, making professional knowledge essential for effective deployment and ongoing management.

Cosmetic Grading Standards

Excellent Grade switches show evidence of very light previous use with only minor scuffing or minimal abrasions on the chassis from standard use, maintaining a professional appearance suitable for visible network installations. Good Grade units remain fully functional but feature more visible signs of wear including light scratches on the external body, moderate case wear, and may include small dings, dents, or paint chips on surfaces.

Quality Assurance and Testing

Every unit is verified refurbished through Reboot IT's thorough testing process, ensuring all features and functions operate to specification. Since 2001, Reboot IT has been an industry expert utilising cutting-edge testing software and methodologies to certify refurbished network equipment. Each switch undergoes comprehensive diagnostics including port functionality verification, PoE output testing, power supply stability checks, and burn-in testing under simulated traffic loads. All units are professionally cleaned, restored to enterprise-grade performance standards, and backed by a 1-year warranty from Reboot IT covering defects in materials and workmanship.
