RHG9628

Flexibility: ATOP’s high-density RHG9628 Rack-mounted managed switch provides the flexibility needed for your application demands. You can choose from among six different Core versions: based on power supply, uplink port configurations and embedded Hardware-Assisted Boundary Clock feature. And you can choose from six different 4- or 8-Port modules to customize your device in a very simple way.

Designed for Substations: Layer-3 routing support BGPv4, IPv4 static routing, RIP v1/v2 and OSPFv2.

Award-winning Performance: RHG9628’s IEEE1588v2 Hardware-PTP version received recognition for nanosecond-level accuracy. This makes RHG9628 one of the most reliable GMC backups. And being embedded with Synchronous Ethernet and with full support for PTP profiles.

High-availability, versatility and power: When equipped with High-Availability HSR/PRP modules, RHG9628 complies with the most stringent redundancy requirements, ensuring no packet loss and guaranteeing GOOSE packets arrive at their respective destinations.
RHG9628‘s high performance provides a network redundant self-recovery mechanism of under 20ms on full load. This enables you to build a reliable network through almost any redundant ring topology. RHG9628 supports ITU-T G.8032 ERPS Ring, IEEE802.1D-2004 RSTP, STP, MSTP, MRP (Manager/ Client), iA-Ring, iA-Chain and many other compatible ring protocols for network redundancy. With a Multifunctional web dashboard, its offers intelligent features such as Quality of service (QoS), IGMP, port mirroring, and security. It is available in two power input variants: one for low-DC voltage (redundant 24~120VDC input) and one for the more popular High-Voltage applications in the distribution grid (redundant 110~240VAC, 24~120VDC or 120~380VDC input). Additional 4 x 10 Gigabit uplink SFP slots allow RHG9628 to be the backbone of the substation.

Consult RHG9628 datasheet to learn more about application and configuration mode.
