Flexible: ATOP's high-density RHG7628 Managed Rack-mount switch will provide you the flexibility your application needs. You will be able to choose among 8 different Layer-3 Routing Core versions (based on power supply and uplink port configurations) and five different 4/8-Port modules and customize your device in a very simple way.

Designed for PoE, in wide temperature: RHG7628 supports up to 24 Gigabit ports in any 8 or 4-port multiple configuration. Specifically designed for bringing power through Ethernet cable virtually anywhere, a maximum output Power over Ethernet of 720W over the 24 ports is allowed (PoE/PoE+ configuration - 802.3af/at). Available in 4 power input variants, it is EN 60950-1:2006 certified and designed to handle the harshest environments. Its fanless design and EMC Level 3 protection guarantee operations from -40 to +75°C.

Powerul and versatile: RHG7628 supports IPv4 and IPv6 Static Routing, RIPv1/v2, OSPFv2, PIM-DM, PIM-SM, PIM-SSM, DVMRP and VRRP for Routing Redundancy. Then, it embeds all features of RHG7528 (layer-2 version), allowing (through ERPS) network self-recovery down to 20ms on full load.  Almost any redundant ring topology is supported, such as ITU-T G.8032 ERPS Ring, IEEE802.1D-2004 RSTP, STP, MSTP, MRP (Manager/Client), iA-Ring, iA-Chain and many compatible rings. 

Automation and IoT ready: The RHG7628 Series is fully EN50155-certified to ensure reliable performance under a wide range of power supply conditions, and it complies with essential sections of EN50121-4 for ground equipment.

Secure: The first Industrial Managed Secure Switch! Protect your LAN from Eavesdropping and impesronation through 802.1AE MACsec. With no additional latency and 100% Gigabit Throughput guarantee, dedicated modules can provide you the internal ultimate security solution.

 

APPLICATION CASES

IEEE 802.1AE protocol (MACsec) provides—to the components that support it—authentication, integrity and confidentiality using strong crypto (AES-128 bit). Since the communication is encrypted hop-to-hop (so, decrypted upon receipt and encrypted again with a different key before forwarding), it can protect your network not only from wiretapping, masquerading, man-in-the-middle attacks and denial-of-service, but also from impersonation and replay attacks. And that’s not all. Since the encryption is carried out by hardware, the full Gigabit Bandwidth is preserved and no additional latency is added to the network.  

Application example

In the below network diagram you can see how easy it is to exploit all features of RHG7628. Different Switches are interconnected through a 10 Gigabit Ethernet Fiber backbone in an OSPFv2 Mesh. The device on the left for example powers the IPcam surveillance System  through PoE/PoE+, provides Industrial-Grade connectivity to the Factory, and guarantees confidentiality to the information by a secured, encrypted, connection. The device on the right bridges the secure connection to the office, ensuring Gigabit-speed, no latency data security.
