To connect and configure the switch from the console by using the CLI:
1. Connect the console port to a laptop or PC by using the RJ-45 to DB-9 serial port adapter. An Ethernet
cable that has an RJ-45 connector at either end and an RJ-45 to DB-9 serial port adapter are supplied
with the switch. If your laptop doesn't have a serial port, use a serial to USB adapter.
