Huawei CX6DSFUIT21D CX-SFUI-1T-E 1Tbps Switch Fabric Unit | 03059570

The Huawei CX6DSFUIT21D, identified by product code 03059570 and model designation CX-SFUI-1T-E, is presented as a switch fabric unit for Huawei network infrastructure. Switch fabric units provide internal data-switching paths between supported processing and interface components within a compatible chassis.

Designed for carrier-grade and enterprise network infrastructure applications, a compatible switch fabric module can help maintain efficient internal data exchange and support the overall performance of the host platform. Before deployment, buyers should verify the exact chassis compatibility, hardware revision, software requirements, and redundancy configuration.

Important Compatibility Note: Confirm the complete part number, board label, supported chassis, and applicable hardware documentation before ordering. Do not rely on a similar-looking model number alone to determine compatibility.

Which switch fabric unit should you choose?

Choose the CX-SFUI-1T-E only after confirming that it is the correct replacement for your existing hardware. A module with a similar capacity or appearance may use a different board revision, interface architecture, or software compatibility matrix.

Q1: What is the Huawei CX6DSFUIT21D used for?

It is identified as a switch fabric unit. This type of module provides internal data-switching paths within a compatible network chassis. Confirm the exact supported system before installation.

Q2: Is CX6DSFUIT21D the same as CX-SFUI-1T-E?

The supplied product information associates these two identifiers. However, their exact relationship to part number 03059570 should be verified against Huawei's official component database or the physical product label.

Q3: Can I replace an existing Huawei switch fabric module with this model?

Only if the host chassis, hardware revision, software version, and redundancy requirements support the replacement. Check the existing module's label before ordering.

Q4: How does this product compare with a higher-capacity switch fabric unit?

A higher-capacity unit may provide greater internal switching bandwidth, but it is not automatically compatible with the same chassis. Compatibility and supported system architecture should take priority over capacity alone.

Q5: What information should I provide when requesting a quotation?

Provide the complete model number, part number, quantity, required condition, delivery destination, and a photograph of the original module label when available. These details help the supplier confirm the correct replacement.

Q6: What after-sales support should a supplier provide?

Ask the supplier to confirm the product identity, condition, warranty period, return policy, and available technical assistance before payment. For replacement modules, request compatibility confirmation wherever possible.

Q7: Can I request a bulk quotation for network spare parts?

Yes. Include the required quantity, destination country, and any specific condition or warranty requirements so the supplier can prepare an appropriate quotation.
