1. Introduction
Founded in 2020 in Shenzhen, China’s renowned tech hub, TEYl Intelligent Technology (Shenzhen) Co., Ltd. is a national high-tech enterprise that integrates independent R&D, manufacturing and global sales of communication IoT hardware. As a professional supplier of enterprise network infrastructure, we develop and supply full-series software routers (Max Series, Mini Series), TY-SW managed switches, T63 navigation hardware and matched accessories to support worldwide digital construction.

This official warranty policy sets unified after-sales standards for all our product lines, providing reliable hardware protection for authorized distributors, system integrators and end enterprise users. All warranty services are based on valid purchase documents and intact product serial numbers (SN).

2. Warranty Duration
Warranty validity starts from the earlier date of product warehouse delivery or official commercial invoice issuance. Tiered warranty terms apply to different product categories:

Max Series Rackmount Software Routers (TY-MAX-DC01, TY-MAX-DB02, TY-MAX-DB01, TY-MAX-DA01), TY-SW Series Switches & T63 Navigation Hardware: 36 months (3 years) free hardware warranty. These enterprise multi-port network platforms are engineered for continuous heavy-duty commercial operation, so we offer long-term full coverage against factory defects.
Mini Series Fanless Industrial Routers (TY-MINI-DD02, TY-MINI-DD01, TY-MINI-DC02, TY-MINI-DC01) & Official Matching Accessories: 24 months (2 years) free hardware warranty, aligned with the design service life of compact fanless industrial network hardware.
Extended Warranty Option: Clients with bulk orders can purchase 1–3 years extended warranty before the standard warranty expires for longer equipment protection.
Every network device carries a unique SN label, which serves as the core credential for all warranty verification. Customers shall keep original invoices and delivery slips properly.

3. Free Warranty Coverage
Within valid warranty period, we provide free repair, spare part replacement or whole-unit exchange for products with inherent manufacturing defects under standard operating conditions:

Free repair or replacement of defective original hardware including mainboards, Ethernet port modules, power supply units and heat dissipation components, when equipment is installed and operated strictly following the user manual within rated voltage, temperature and humidity ranges.
Lifetime free official firmware updates, routing function optimization and remote configuration guidance for all software router models, to help clients upgrade network performance and adapt to future networking demands.
Free remote fault diagnosis, network topology design consultation and technical guidance for switches and navigation devices.
If technical teams confirm that faults cannot be repaired within a reasonable cycle, we will replace the faulty unit with an identical or equivalent-performance model at zero extra cost.
4. Non-Warranty Circumstances
Free warranty service is not available for damage caused by the following situations; we can provide paid maintenance service upon customer request:

Damage from unauthorized disassembly, self-modification of internal circuits, flashing unofficial third-party firmware, or defacing/removing the SN label.
Malfunctions induced by improper installation, out-of-spec power input, water ingress, physical impact, dust and chemical corrosion, especially for Mini compact routers with precise integrated heat dissipation structures.
Damage resulting from force majeure events such as lightning strikes, power surges, floods and other natural disasters.
Products purchased from unapproved resellers without formal purchase certificates.
Wear and aging of consumable parts caused by long-term overloaded operation beyond the product’s rated working limits.
5. Warranty Claim Process
Submit Application: Clients submit fault descriptions, product SN codes, purchase vouchers, fault photos or videos via our global after-sales email, official hotline or local authorized distributors.
Remote Diagnosis: Our professional engineering team completes fault assessment within 1 working day to confirm whether the issue qualifies for free warranty service.
RMA Return Arrangement: For eligible warranty cases, we issue an official RMA authorization form. TEYl bears both inbound and outbound shipping costs for confirmed warranty repairs.
Repair & Reshipment: All repairs or unit replacements will be finished within 3–7 working days after receiving faulty goods, then shipped back to customers at our expense.
6. Supplementary Terms
This warranty service only covers the first original purchaser and cannot be transferred to second-hand buyers without TEYl’s official written approval.
After any model is discontinued, we guarantee a 5-year supply of spare parts and continuous technical support to ensure stable long-term operation of clients’ network infrastructure.
TEYl reserves the right to adjust this warranty policy with prior public notification, and all terms comply with international trade rules and China’s relevant quality supervision laws.
