INDUSTRIAL MANAGED, 10/100 ETHERNET SWITCHES - WITH GIGABIT OPTIONS
B&B Electronics’ managed Elinx family of Industrial rack mount Ethernet switches has been designed to meet light and heavy Industrial communication requirements. The switches feature built-in fiber optic options, gigabit options with copper and SFP combination ports, broadcast storm control, and more.
Functional Description
B&B Electronics Elinx family of Industrial rack mount Ethernet switches have been designed to meet light Industrial communication requirements. The ESW726 Managed family offers a variety of Industrial models. The switch configurations range from 26 ports RJ45 copper to RJ45 copper with multi mode, single mode, and or SFP gigabit ports. Two ports can be used for network redundancy by implementing our RingOn technology. RingOn has been developed to provide a rapid recovery system for Industrial networks. If any part of the ring disconnects the network communications will automatically be restored by RingOn technology.
IGMP
The Internet Group Management Protocol (IGMP) is a communications protocol used to manage the
membership of Internet Protocol multicast groups. IGMP is used by IP hosts to establish multicast group
memberships. This allows the port to detect IGMP query and report packets and manage IP multicast traffic
through the switch.
Web-based Management
Each switch has an embedded HTML web site residing in flash memory, offering advanced management features and allows users to manage the switch from anywhere on the network through a standard web browser.
VLAN Configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. This allows you to isolate network traffic so that members of a VLAN will only receive traffic from other members of the same VLAN. Creating a VLAN from a switch is the logical equivalent of reconnecting a group of network devices to another Layer 2 switch. However, since it is a virtual network, the network devices remain connected to the same switch physically. Both port-based and 802.1Q (tagged-based) VLAN are supported.
