RHG7528 Series

Industrial Rack-Mount Modular Managed Gigabit Ethernet PoE Switch with up to 24 x Gigabit ports and 4 x 10 Gigabit SFP uplink slots, wide temperature

10/1GbE Modular Layer2 Managed PoE Rackmount Switch

  • 128 Gbps max. switching capacity and 95.23 Mpps max. switching fabric
  • Designed to operate in harsh environments of -40°C to 75°C
  • Flexible modular configuration, 3 Module-dedicated slots
  • Swappable modules for flexibility to work in all kinds of scenarios
  • Up to 24x PoE ports, max. power budget 720 W
  • 4x 10 GbE /1 GbE uplink SFP slots
  • 4 kinds of power input available for different harsh environments
  • ITU-T G.8032 ERPS Ring, RSTP, or MRP (Manager/Client) redundancy
  • EN50155 / EN50121-4 certified for railway applications
  • Precision time synchronization with IEEE1588v2 P2P/E2E TC, delay within 50ns
  • Compliant with IEC 62443-4-1 and IEC 62443-4-2 security standards

Flexible and powerful
ATOP’s high-density RHG7528 layer2-managed rackmount switch provides the flexibility to meet all kinds of requirements. Customization is made easy with 8 different switch cores, differing in power supply and uplink ports, and 3 swappable modules of different port types. Of these, PoE ports allow both power and data transmission to wherever the Ethernet cable can reach. With 3 modules of 8 ports each, RHG7528 supports up to 24 Gigabit PoE/PoE+ (IEEE 802.3af/at) ports, so has at maximum 720W total power budget.

ugged and resilient
Designed to work in all kinds of harsh environments, RHG7528 is EN 60950-1:2006 certified, available in 4 types of power input, fanless, and provides EMC level-3 protection. Reliable operation is guaranteed in the wide-range temperature of -40°C to +75°C. Various supported ring protocols enable self-healing ability for your network. ITU-T G.8032 ERPS Ring can even recover the network within 25 ms on full load of 250 devices. User-friendly WUI allows simple setup of basic functions like VLAN, QoS, IGMP, as well as network diagnostics via Port Mirroring.

Proven quality
The RHG7528 Series is compliant with IEC 62443-4-1 and IEC 62443-4-2 standards, which means that its development process as well as product features achieve world-class industrial network security. In addition, ACL by IP/MAC and 802.1x port access control with RADIUS filters unauthorized hosts, helping to keep your network safe. Furthermore, the RHG7528 Series is EN 50155-certified to ensure reliable performance under a wide range of power supply conditions, and complies with essential sections of EN 50121-4 for railway ground equipment.
