Installation and Start-up: Rack-based and RX7i Embedded Interface24 PACSystems* RX7i & RX3i TCP/IP Ethernet Communications User Manual GFK-2224Q3.2 Module InstallationFor general information about module and system installation, or if the installation requires CE Markcompliance, refer to the PACSystems RX7i Hardware Installation Manual, GFK-2223 or the PACSystems RX3iSystem Manual, GFK-2314.Installing an RX7i CPU with Embedded Ethernet InterfaceWarningDo not insert or remove the CPU module with power applied. This could causethe CPU to stop, damage the module, or result in personal injury.1. Record the 12-digit hexadecimal MAC Address from the printed label located on the rear wall of CPUbattery compartment. The label is visible when the battery is removed from its compartment. (The batterydoes not need to be disconnected to temporarily remove it from the compartment.) For compatiblebatteries and battery installation procedures for specific CPUs, refer to the PACSystems RX3i and RX7iControllers Battery Manual, GFK-2741.2. Install the CPU in the rack. Refer to PACSystems RX7i Hardware Installation Manual, GFK-2223 forinstallation instructions.3. Set the PLC to Stop mode via the Run/Stop switch or the programming software.Installing an RX7i Ethernet Interface Module1. Record the 12-digit hexadecimal MAC Address from the printedlabel on the Ethernet Interface. The label is visible only withmodule out of the rack.2. Be sure the rack power is OFF.3. Slide the module into the slot for which it was configured in thesystem. (Must go into main rack.)4. Press the module firmly in place, but do not force the module.Tighten the screws on the top and bottom tabs.5. Connect one or both of the network ports on the EthernetInterface to the Ethernet network.6. Turn on power to the PACSystems rack.7.
