Verified Reboot Refurb Quality Assurance

Every Cisco SG300-28 switch undergoes Reboot IT's rigorous Verified Reboot Refurb testing process, ensuring all 28 ports, management interfaces, routing functions, and security features operate flawlessly. As networking experts since 2001, Reboot IT employs cutting-edge diagnostic software to thoroughly validate each switch's switching capacity, VLAN configuration, QoS performance, and firmware integrity before certification. All units are comprehensively tested to meet strict operational standards, guaranteeing reliable performance for your business network.

Cosmetic Grading Standards

Reboot IT's certified refurbished switches are available in two cosmetic grades to suit different budgets whilst maintaining identical performance standards. Excellent Grade switches show minimal signs of previous use with only very minor scuffing or light abrasions on the metal chassis from standard handling, whilst maintaining pristine port conditions. Good Grade units are fully functional but may display more visible wear including light scratches on the external housing, minor paint chips, or small dings from previous rack installation, though all ports and functionality remain perfect. Regardless of cosmetic grade, every switch delivers the same enterprise-level performance and reliability.
