Quad-core 1.4GHz ARM Cortex-A15, 1GB RAM, 10x Gigabit RJ45 + 1x SFP+ 10Gbps cage, PoE-out on port #10, 1U rackmount metal chassis — a distinct chassis from the already-seeded hAP ac2/ax2/ax3 (home APs), hEX RB750Gr3 (5-port, no rack ears), and RB5009 (7-port, different chassis). MikroTik official KB: "Older MikroTik devices come with the login 'admin' and no password out of the box," but "newer models do have a default password set in the factory," printed on the serial-number sticker, packaging, or included quick guide — current-production units ship with a per-unit password rather than a shared default.

Factory reset

Hold the reset button while powering on until the port LEDs flash, then release to restore RouterOS factory defaults.
