<p><strong>Dear Network UPS Tools
Community,</strong></p>
<p>I am writing to you with a problem I'm
encountering while setting up my Ippon Innova TBE 2000 UPS with
NUT on my Linux system.</p>
<p>According to the NUT hardware
compatibility list, my UPS model should be supported. However, I'm
experiencing difficulties in configuring it and cannot establish a
stable connection.</p>
<p>Here is the information about my
system and configuration:</p>
<ul>
<li>
<p><strong>UPS Model:</strong> Ippon
Innova TBE 2000</p>
</li>
<li>
<p><strong>OS:</strong> Ubuntu

<p>I am using the <code>blazer_usb</code>

<p>I kindly request your assistance

nuances or known peculiarities with this UPS model or driver that
I should be aware of.</p>
<p>Any advice or recommendations would
