The Huawei AR651 is a compact enterprise router designed for branch and small office deployments. With 4 x GE RJ45 interfaces and 500 kpps forwarding performance, this Huawei router delivers reliable wired connectivity for everyday business traffic. Its 256 MB Flash and 512 MB SDRAM provide sufficient resources for routing services, while the low 8W maximum power consumption and universal AC 100 V to 240 V power supply make it energy-efficient and easy to deploy across diverse commercial environments.
