Switch Start-Up

reboot (using the reset button or restart command), it performs a series of tests
and sends messages to the terminal or PC connected to the ASYN0 port. After
the switch successfully starts, a prompt is displayed for you to log in. Refer to
the Installation and Safety Guide for basic login instructions or to the Getting
Started chapter in the Software Reference.
