The Allen-Bradley 1783-EMS08T switch is a managed Ethernet switch. It comes with eight 10/100 Mbps rated RJ45 ports and an optional fiber port. The SFP modules supported by the switch include the 1783-SFP1GSX and 1783-SFP1GLX modules. The 1783-EMS08T switch is part of the Stratix 6000 series. The rated power input for the 1783-EMS08T switch is 250 milliamps at 24 Volts DC. The range of input voltages supported by the switch is 12 to 48 Volts DC. The peak power dissipation for the 1783-EMS08T switch is 5.8 Watts and the peak thermal dissipation is 24.6 BTU/hour at 60 degrees Celsius. The network protocols supported by the switch include the TCP/IP, Ethernet/IP, Telnet, Http, DHCP, BOOTP, FTP, IGMP, and the SMTP protocols. There are a total of 16 port indicators and 3 status indicators on the 1783-EMS08T switch.

The Ethernet/IP features available on the 1783-EMS08T switch include active connections, bandwidth alarming, and port control features. Switch features available include VLAN, port mirroring, DHCP server, IGMP snooping, and IGMP query features. The maximum inrush current level for the switch is 2.2 Amps. The working temperature range and the storage temperature range for the 1783-EMS08T switch are 32 to 140 degrees Fahrenheit and -40 to 185 degrees Fahrenheit, respectively. The switch is sensitive to ESD (electrostatic discharge). Therefore, safety precautions when handling the device must be observed which includes wearing of a grounded wristrap, touching a grounded object to discharge static electricity, touching of electronic components should be avoided, and the switch should be stored in static-safe packaging when not in use. In hazardous environments, the wiring should only be connected when power is disconnected.

This module is provided with status indicators composed of Sixteen (16) port indicators for reporting of link and activity and Three (3) status indicators used to report the overall module operation, mode diagnostic. This module features MAC ID management, bandwidth alarming, port control, link status, scaled bandwidth information, connections active.

The 1783-EMS08T supports expansion and installation of 1 Gigabyte Fiber Optic Transceiver or Single Form-factor Pluggable interface for interfacing Fiber Optic medium used for faster and noise immune communication network.
