I just bought my very first router, it's a DeWalt DW621 (it has a cord, no batteries). I plugged it in and pressed the on-switch, but I'm getting no response from the router.

Did I forget to remove some safety pin, or is this likely an out of box failure?

I'm not familiar with that specific router, but the instruction manual (page 9) indicates it has a lock-on/lock-off safety feature:

Lock-On/Lock-Off Switch (Fig. 7) The lock-on/lock-off switch is located in the handle on the right side. The router is normally locked-off. To start the router, press the thumb lock and squeeze the trigger. To lock the switch on, squeeze the trigger, press the thumb lock forward and release the trigger. To turn the router off, release the switch. If the tool is locked-on, press the trigger again and release the switch.

Make sure you press that thumb lock switch when squeezing the trigger.
