OverviewIntroduction 1-31.1.1 ConnectivityThe 6E233-49 SmartSwitch connects to Ethernet networks or workstations through the four RJ21connectors on the front panel. These ports support Unshielded Twisted Pair (UTP) cables with animpedance between 85 and 111 ohms at lengths up to 100 meters. These ports are IEEE 802.3u10BASE-TX compliant.The 6E233-49 has a slot for an optional HSIM to provide additional connectivity to variousnetworking technologies.1.1.2 Auto-NegotiationThe front panel ports on the 6E233-49 SmartSwitch module have the ability to auto-negotiate thetype of connection required to provide a link to another device. During Auto-Negotiation, twodevices automatically exchange information “telling” each other what their operating capabilitiesare. The Auto-Negotiation feature targets the maximum capabilities that can be reached betweenthe two devices.When Auto-Negotiation is supported at both ends of a link, the two devices dynamically adjust tofull or half duplex operation based on the maximum capability that can be reached between thetwo devices. If the device connected to the 6E233-49 SmartSwitch cannot auto-negotiate, the6E233-49 SmartSwitch interface operates according to the capabilities of the other device.1.1.3 Runtime IP Address DiscoveryThis feature enables the module to automatically accept an IP address from a Boot Strap Protocol(BootP) server on the network into NVRAM without requiring a user to enter an IP addressthrough Local Management.When the module is connected to the network and powered up, Runtime IP Address Discovery(RAD) checks the module for an IP address. If one has not yet been assigned (module and 6C105chassis IP address set to 0.0.0.0), RAD checks to see if any of the module interfaces have a link. Ifso, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain anIP address from a RARP or BootP server on the network.The RAD requests start out at an interval of one second. The interval then doubles after everytransmission until an interval of 300 seconds is reached. At this point, the interval remains at 300seconds. The RAD requests continue until an IP address is received from a RARP or BootP server,or an IP address is entered using Local Management.NOTENOTENOTENOTEThe module will reboot after RAD is successful.Artisan Technology Group - Quality Instrumentation ...
