D2G124-12P Cannot access management

D2G124-12P running current firmware.

Handed the unit to a coworker for testing of a new RADIUS system. In that process, we attempted to enter the admin password too many times.
We figured we could let it sit and it would unlock.
Well, it's been two weeks and it's still not unlocked.

I have no output from the console port.
not locked, just nothing out of it.
Even during boot, it doesn't show anything.
I've checked all the baud rates, still no love.

It's a dev unit, but I'm fairly sure that I didn't disable the console port.

Seeing as I don't have any console access, pressing the reset button to clear the password doesn't help.

All the lights are green and it does function as a switch just fine.

Is there a way to hard factory reset this thing?
Any other means of gaining access?

To connect to a D2 console, you need more than just a rollover cable. You need a standard ethernet cable and the serial adapter that came with the D2. Once you get into it via console, the password can be cleared by removing the config from the pre-boot menu. There is also a small password reset button on the front of the d2. Just press it for 5 seconds after the switch is booted. Password for admin will be blank.
I'm using the supplied RJ45-to-serial cable.
I've tried another RJ45 serial cable and several adapters.
All deliver the same response: absolutely nothing.

consoling into another switch with the same cables works, so I know my equipment is fine.

just to make sure - the "other" switch is also a D2 ?

The other switches are X450-G2s, and I've tried all the cables I have and they work on them.

Any other D2 to test the cable just to make sure you've a working console cable setup.

I know it's a pain in the.... I've 5 different console cables in my backpack just because every model uses a different cable pinout 😞
