Hi. I have a QFX 5110-48S switch. I started it to check the serial number for generating the license, but I had to go to a meeting, therefore I had to switch it off. I didn't setup the root password. Now I am not able to start it. It runs FreeBSD and requires the login and password. I don't know how to run the initial setup process. Can you help me?
To connect and configure the switch from the console: 1. Connect the console port to a laptop or PC by using the provided RJ-45 cable and RJ-45 to DB-9 serial port adapter. The console (CON) port is located on the management panel of the switch. 2. Log in as root. There is no password. If the software booted before you connected to the console port, you might need to press the Enter key for the prompt to appear. login: root 3. Start the CLI. root@% cli 4. Enter configuration mode. root> configure 5. Add a password to the root administration user account.  root@# set system root-authentication plain-text-password New password: password Retype new password: password 6. (Optional) Configure the name of the switch. If the name includes spaces, enclose the name in quotation marks (“ ”).  root@# set system host-name host-name 7. Configure the default gateway.  root@# set routing-options static route default next-hop address 8. Configure the IP address and prefix length for the switch management interface.  root@# set interfaces em0 unit 0 family inet address address/prefix-length NOTE: The management ports, em0 (C0) and em1 (C1), are located on the FRU end of the QFX5110-48S. 9. (Optional) Configure the static routes to remote prefixes with access to the management port.  root@# set routing-options static route remote-prefix next-hop destination-ip retain no-readvertise 10. Enable Telnet service.  root@# set system services telnet 11. Enable SSH service.  root@# set system services SSH 12. Commit the configuration to activate it on the switch.  root@# commit
