C9300 - Can't Get Into WebUI

I have tried accessing the webUI on a fresh out-of-the-box C9300-48T-A, with no luck -- not getting addresses from on-board DHCP. Per Cisco's (and everyone else's) instructions, you have to:

• Set your PC to receive DHCP - done
• Boot up the switch with nothing connected - done
• Don't enter anything at initial config prompt - done (connected via console to ensure the prompt is still there)
• Connect your PC to any port on the active supervisor (used straight-through and cross-over cable, just to verify) - done (tried multiple interfaces)
• Wait 3 minutes - done
• DHCP should assign an IP of 192.168.1.1 to your PC - This is where it fails. I'm just getting a 169 APIPA every time. I've also tried on a MacBook and different PCs, just in case.

I've tried setting the port as a static 192.168.1.1, in case DHCP isn't doing it's thing for whatever reason, but no such luck.

I've tried entering https://192.168.1.1 into many different browsers, cleared cache, but no luck.

Only extras we have on this switch, is it shipped with a 4X module, and 2 PSUs -- don't think any of that should matter.

EDIT: We went ahead with the base config, and after configuring our management VLAN IP, we're able to get into the WebUI via that IP -- so it seems the out-of-the-box DHCP just wasn't configured, not assigning the IP to the host. Not really a solution, since this was "supposed" to be automatically assigned without any CLI config, but oh well, it's a result. Will test the WebUI on the remaining 4 we have just to see if they behave any differently.
