HUAWEI USG6670-DC NextGeneration Firewalls

USG6670-DC with Published Replacement

USG6670-DC, Huawei part 0235G7GA, is a DC-input Secospace USG6670 firewall. Its lifecycle and replacement path are explicitly documented by Huawei.

Lifecycle dates

Huawei states an end-of-marketing date of December 31, 2017 and a planned end-of-service date of December 31, 2022 for USG6670-DC.

Replacement named by Huawei

The same notice names USG6660-DC as the replacement. Compare , but validate throughput, ports, boards, licenses and software behavior before treating that migration as equivalent.

DC electrical acceptance

Verify the installed DC power modules, input range, polarity, grounding, feed redundancy and circuit protection from the physical labels and hardware documentation.

Installed-option inventory

Capture interface boards, storage, fan modules, software release, configuration export, serial numbers and licenses. The SKU confirms the appliance and power class, not every option fitted to a used unit.

Procurement outcome

Use this page for legacy replacement or spares evaluation. A production order should include a supportability statement and a tested migration plan.
