Hard reset RB450G

Hello, I add a bad configuration to my RB450G. And now I can not access to it.

How could I make a hard reset? I try to ipen the box, and do a contact in the reset pins with a metel, bit nothing happens. I makes a beep but still can not to access.

Which is the correct steps? Switc off, contact the pins, switch on, wait to the beep?

Could I reset from serial port?

I will really appreciate your help, I don’t know how to rescue my RB.

Best regards.

Wait until the router lights start flashing
Then release to be restarted

Thanks!

I press the reset until light start blinkikg and it works!

Best regards
