    (Gigabit Ethernet). The Console Port The Switch is equipped with a RS-232 serial port (located on the rear of the Switch, as shown in Figure 2-3) that allows you to connect to a computer (for configuration purposes) using the provided serial cable.

  • Page 6: Rack-Mounting The Switch

    You can now re-connect the cables to the Switch. Powering on the Switch To power on the Switch, simply connect the AC power cord to the back of the Switch, and then plug the power cord into an electrical outlet. The Switch will boot up within approximately 30 seconds.
