Unable to enter our credentials on IE4000

[frankawit8]

Hello 

I am a newbie in network, I just want to ask help regarding the issue where I can't log in to our IE-4000-8GT8GP4G-E.

Also the "power supply vee under voltage and lockout" is keeps on showing and I think because of that error message that's why we can't log in.

What can I do with this?

Yes sir Actually two of our switch were experiencing like this, our IE SW1 is for RMA right now since we got the logs, the IE SW2 is we can't access or log in using our credentials. I need to access first on the switch to gather logs. What can I do is there a way please help me sir.

@marce1000 and @balaji.bandi already gave you te information, but a little brief

power down the device and power on again
the collect the log from power-on until the repeated message repeats itself

most likely the power supply used is faulty
because of this the IE400 never fully boots up, so you never get to a login prompt
so above log is all you can collect

if possible exchange the power supply and test again

May be worth connecting console cable and check - is the device booted as expected.

Look at the installation guide :
