Best procedure for shutting down the pi 4

Installation
1

I just booted HA with my pi4. The message is:
… undervoltage detected!
_

The _ is flashing.

There is no command line accessible. I would rather use the best procedure so not to affect the system.

I am a fluent linux system user, porteus a slackware derivative, but also sometime, arch, debian and ubuntu.

What should I do?

It has not booted up yet. It is in the Hardware check, like on a PC. Pull the plug (Network cable if PoE, USB-C if that is used, or the power brick on it).
Find a good power brick as a check (12 VDC 2 AMP)

Thanks for the quick response.
I will get the appropriate power supply.
