Supports VLAN, SNMP v1/v2c/v3, ACL, IP source guard for Ethernet security
RLH industrial Ethernet switches are engineered to provide reliable network performance in harsh environments. The 4+2 Managed Fiber Switch is an industrial switch with 4 10/100BASE-T ports and 2 fiber ports.The 100BASE-FX fiber ports support single and dual fiber configurations, singlemode and multimode, ST and SC connectors. This fully manageable Light Layer 3 switch, combines the functionality of a Layer 2 switch with basic Layer 3 routing capabilities.
RLH Switches are engineered with robust features and construction to meet the demands of a variety of industrial applications. The switch includes standard design features such as 12~48VDC dual redundant power inputs, fault alarm relay, DIN rail and wall mounting hardware, and -40°C to 75°C operating temperature range, and is an ideal solution for a wide range of utility and automation network environments.
