RHG7628 Series

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 3 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 within -40 and +75°C, with 24 PoE ports running full power and makes it suitable to be used for almost every application.

Powerul and versatile: RHG7628 supports IPv4 Static Routing, RIPv1/v2, OSPFv2, IGMP, IGMP Snooping, PIM Dense Mode and Sparse Mode, 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 RPS Ring, IEEE802.1D-2004 RSTP, STP, MSTP, MRP (Client), iA-Ring, iA-Chain and many compatible rings. Endless additional features are provided.

Automation and IoT ready: conforming with Profinet CC-B v2.33 makes RHG7628 the perfect candidate for being the backbone of your Industrial automation network.

The RHG7628 Series is fully EN50155-certified to ensure reliable performance under a variety of power supply conditions, such as voltage variations, power interruptions, and supply changeovers, 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.
