Series Description

Flexibility: ATOP’s high-density RHG9528 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: RHG9528 supports up to 24 Gigabit ports in any 8-port multiple configuration. Specifically designed for IEC61850 substation backbone use, it is fully certified to meet all IEC61850-3 hardware requirements – such as EMC Level 3, 4 and 5 requirements, Wide temperature range and High availability.

Award-winning Performance: RHG9528’s IEEE1588v2 Hardware-PTP version received recognition for nanosecond-level accuracy. This makes RHG9528 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, RHG9528 complies with the most stringent redundancy requirements, ensuring no packet loss and guaranteeing GOOSE packets arrive at their respective destinations. RHG9528‘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. RHG9528 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 HighVoltage applications in the distribution grid (redundant 110~240VAC, 24~120VDC or 120~380VDC input). Additional 4 x 10 Gigabit uplink SFP slots allow RHG9528 to be the backbone of the substation.
