Support
Technical help throughout the product lifecycle.
Begin with a model-specific request, escalate to eRMA when service is required, and stay informed about lifecycle and security notices.
Technical Support
Send the engineering team the context needed to help.
Include the exact model, firmware version, network behavior and troubleshooting already completed. This reduces unnecessary follow-up.
eRMA Management
Diagnose first. Return only when service is required.
Technical support may resolve the problem without shipping the equipment. When a return is necessary, obtain an RMA number before sending the product.
