New from Contemporary Controls is the EISK8M-100T, a rugged managed 10/ 100 Mbps Ethernet switch with eight copper ports. Intended for cost-effective SNMP managed applications, the unit is compact and rated over the industrial temperature range.
Besides having the standard plug-and-play features found in unmanaged switches, this unit supports management features such as authentication, IP address assignment, trunking, port mirroring, virtual local area network (VLAN), port forwarding, Quality of Service (QoS), programmable fault relay, cable redundancy, rate limiting, port security and Internet group management protocol (IGMP) snooping.
Each unit can be configured via its web pages, and can be powered either from a low-voltage AC or DC source. They provide standard plug-and-play features such as auto-negotiation and auto-MDIX. These features, plus full-duplex, can be individually set for each copper port. The copper ports can auto-negotiate 10 Mbps, 100 Mbps, half- or full-duplex.
In addition to one power LED and one CPU status LED, each port has LEDs showing link/activity/data rate by colour. Flashing indicates port activity. The EISK8M series is designed for DIN-rail mounting. There are several low-voltage AC or DC powering options from 24 V a.c. or from 10 to 36 V d.c. Provisions exist for redundant power connections.
