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.

Which version do I need?
This page covers the RHG9528 series, ordered as a core plus up to three modules. Six cores: RHG9528-410GSFP-DC (redundant 24-120 VDC), -AC (redundant 100-240 VAC) and -HV (redundant 120-380 VDC), plus -SB-DC, -SB-AC and -SB-HV, which add a hardware-based IEEE 1588v2 boundary clock, SyncE and a 1PPS BNC output. All six have 4 × 1/10 Gb SFP uplinks and 3 module slots. Modules: RHG9528-M1 8 × Gb RJ45; M2 8 × Gb SFP; M3 4 × Gb RJ45 with an RS-485 terminal block for IRIG-B output; M4 4 × Gb SFP with IRIG-B output; M5 4 × Gb RJ45 with HSR/PRP; M6 4 × Gb SFP with HSR/PRP. HSR/PRP comes only from M5 or M6 (2 groups each); SyncE is carried on M1 to M4 but not on M5 or M6. All modules list IEEE 1588v2 TC and BC capability, with the hardware boundary clock active on -SB cores. Choose the core by supply range and by whether the switch must be a PTP boundary clock (-SB); add M5 or M6 for PRP or HSR to IEDs, and M3 or M4 where legacy IEDs need IRIG-B. The RHG9628 is the Layer 3 equivalent.
Typical applications for the RHG9528
- Substation station-bus backbone on a 10 GbE fibre ring
- PRP LAN A/LAN B or HSR rings to protection IEDs via M5/M6 modules
- PTP boundary clock between a grandmaster and bay-level IEDs (-SB cores)
- IRIG-B time distribution to legacy IEDs via M3/M4 modules
- Distribution-grid sites on 120-380 VDC or 100-240 VAC supplies
- GOOSE networks needing IEEE C37.238 / IEC 61850-9-3 PTP profiles

RHG9528 — frequently asked questions
Which RHG9528 modules provide HSR and PRP?
Only the RHG9528-M5 (4 × Gb RJ45) and RHG9528-M6 (4 × Gb SFP), each arranged as 2 HSR/PRP groups. ATOP's guide lists up to 4 HSR/PRP ports per switch; modules M1 to M4 do not carry HSR/PRP.
What does the -SB suffix mean?
-SB cores add a hardware-based IEEE 1588v2 boundary clock and full transparent clock, Synchronous Ethernet and a 1PPS BNC output. Non-SB cores still provide hardware E2E and P2P transparent clock with delay within 50 ns.
What power inputs are available?
Three, each redundant: -DC for 24-120 VDC, -AC for 100-240 VAC and -HV for 120-380 VDC, with the same three choices on the -SB cores.
How many ports can it take?
Up to 24 Gigabit RJ45 or SFP ports on three module slots, plus 4 × 1/10 Gb SFP uplinks on the core, 28 ports in total.
How fast does it recover from a link failure?
Under 20 ms on full load with ITU-T G.8032 ERPS, and it also supports STP, RSTP, MSTP, MRP (Manager/Client), iA-Ring and iA-Chain. With HSR/PRP modules, GOOSE messages see zero packet loss.
Which certifications does it hold?
IEC 61850-3 and IEEE 1613 for substation use, plus UL 62368-1 and EN 62368-1 safety. It supports the IEEE C37.238 and IEC 61850-9-3 PTP power profiles and security features based on IEC 62443.
What is the difference between the RHG9528 and the RHG9628?
They share the chassis, core power options, modules and certifications. The RHG9528 is Layer 2 only, while the RHG9628 adds Layer 3 routing (static, RIP, OSPF, PIM and BGP per ATOP's guide).
