Chapter 2 Tropos Routers Installation Guide, Models 6410 and 6420 32Ethernet PortsThe pin assignments on the Ethernet ports (the LAN port on all models and the MGT port onmodels where the MGT port is an Ethernet port) are industry-standard. They are shown in thefollowing table.NoteUse Cat6 cable for Gigabit Ethernet.Serial PortsTropos 6410 and 6420 routers that are equipped with serial ports can support serial clients onRS-232 or RS-485 interfaces. The serial port can also be used to power the router.The router can support the following serial client scenarios. Before installation determine theinstallation scenario and the appropriate powering option for that scenario.TABLE 3 Ethernet Port Pin AssignmentsPin LAN Port10/100/1000Base-TMGT Port10/100Base-T1 TxRx_A+ Tx +2 TxRx_A- Tx -3 TxRx_B+ Rx +4 TxRx_C+ Power +5 TxRx_C- Power +6 TxRx_B- Rx -7 TxRx_D+ Power -8 TxRx_D- Power -TABLE 4 Serial Client ScenariosWired Serial Client Scenario Recommended Wiringone RS-232 serial client • Connect the wired client to the MGT port on the routeraccording to the pin assignments in Table 5.• Provide power to the router on the MGT port according tothe pin assignments in Table 5.
