First whole-brand coverage of Juniper's branch-firewall line, same enterprise category as the existing Fortinet/WatchGuard/Sophos/Barracuda rows. Juniper's SRX300 quick-start documentation states: "You don't need a password if you're running the factory default," and the general Junos user-access docs add: "Initially, you log in as the user root with no password."

Factory reset

Attach a console cable or connect to a LAN port and browse to the default J-Web address 192.168.1.1. Log in as root with no password, then run 'cli' to reach the command line. To return a configured unit to factory state, run 'request system zeroize' (wipes all config) or reimage Junos OS.
