3.Check the front-panel LEDs as the device is powered on to be sure the Power LED is on. If not, check that the power cable is correctly plugged in.

4.If you have purchased a Redundant Power Supply, connect it to the switch and to an AC power source now, following the instructions included with the package.

Connecting to the Console Port

The RJ-45 serial port on the switch’s front panel is used to connect to the switch for out-of-band console configuration. The on-board configuration program can be accessed from a terminal or a PC running a terminal emulation program. The pin assignments used to connect to the serial port are provided in the following table.
