3Com Router 6000 FamilyInstallation ManualChapter 3Installing the Router3Com Corporation3-5II. AC power socket (recommended)You are recommended to use a three-terminal single-phase power socket with ground contact,which must be grounded reliably. Normally, the ground contact of the power supply system in abuilding was buried during construction and cabling. Still, before connecting the AC-inputpower cord, you must make sure that the power supply of the building is well grounded.III. Connecting the AC-input Power CordStep 1: Check that the PGND is securely connected to the earth ground.Step 2: Insert one end of the power cord accompanying the router into the power socket on thechassis rear panel, and fix the cable onto the cable-retention clip with a cable strap. Connectthe other end of the cable to an AC power source at your installation site.Step 3: Check that the PWR LED on the front panel of the router is on for correct connection.3.7 Connecting the Console TerminalI. Console portThe Router 6000 provides an RS232 asynchronous serial console port (CON) for routerconfiguration. For its attributes refer to the section “RPU”.II. Console cableA console cable is an eight-wire shielded cable. At one end of the cable is a crimped RJ-45connector to the console port on the router; at the other end of the cable is a DB-9 (female)connector to the serial port on the console terminal.The following figure illustrates the console cable.AAFigure 3-5 Console cableIII. Connecting the console cableWhen configuring the router through a console terminal, follow these steps to connect theconsole cable:Step 1: Select a console terminal. It can be a standard ASCII terminal with a RS232 serialport, or more commonly, a PC.Step 2: Power down the router and the console terminal; connect the RS232 serial port onthe console terminal to the console port on the router through the console cable.
