Repeated Automatic Reboot Of The Device
<p>[TOC]</p>
<h3>I. Problem Phenomenon</h3>
<p>The device keeps rebooting and does not work properly.</p>
<h3>II. Analysis steps</h3>
<p>1、Checking whether the equipment is under-voltage and does not reach the starting voltage of the equipment, causing the equipment to keep restarting.
2、Hard disk / SD card failure may cause the device has not been able to boot, remove the storage device and then turn on the computer can determine whether the storage device failure.
3、Whether the host has abnormal heat (may need to exclude the host external settings load is too large).
4、Observe whether the device has any functional modules that work abnormally and cause the device watchdog to restart the whole machine automatically (e.g. GUI stuck).
5、Whether the device is set for a scheduled restart and the current time has not reached the power-on time.
6、Whether the equipment is set to shut down at low voltage and the current voltage is unstable, resulting in repeated switching on and off.
7、Checking whether the power of the power adapter meets the power supply requirements of the equipment.</p>
<h3>III. Operating instructions</h3>
<h4>1、Check system voltage</h4>
<ul>
<li><strong>DEVICE STATE-Sensosr-Voltage</strong> check the voltage value, whether in the normal boot voltage value jump back and forth, usually the normal working voltage of the equipment in the range of 8-36V, depending on the equipment model, the minimum working voltage is not the same, the specific can consult our professionals.。</li>
<li>The working voltage of 12V vehicle is 9~16V, below 9V will shut down；</li>
<li>The operating voltage of 24V vehicle is above 17.5V, below 17.5V will shut down；</li>
</ul>

<h4>2、Checking disk status</h4>
<ul>
<li><strong>DEVICE STATE-Disk</strong> check whether the disk is recognized normally. If the disk is accessed and the status shows that it does not exist, you need to confirm whether the disk is normal, and you can replace the disk to confirm again.</li>
<li>If the disk status shows normal, if the status shows error, etc., the disk partition format is incorrect or the disk is faulty, you need to wait for automatic formatting or choose manual formatting, and then observe if it can show normal.</li>
<li>The disk has been in abnormal or normal-2 status, etc. You can scan the disk to troubleshoot the presence of bad blocks by using a PC-based disk scanning tool.</li>
</ul>

<h4>3、Observe the host case temperature</h4>
<ul>
<li><strong>DEVICE STATE-Sensosr-CPU temperature</strong>Checking whether the equipment is in a high temperature environment for a long period of time, with a maximum temperature of 75°C supported by the equipment.</li>
</ul>

<h4>4、Check the device function items</h4>
<ul>
<li>Unplug the camera and then observe if there is still a dead reboot.</li>
<li>Removing the disk and then observing if there is still a dead reboot.</li>
<li>Turn off the AI function and then observe whether there is still a dead reboot.</li>
<li>Shutting down the central protocol and then observing if there is still a dead reboot.</li>
<li>Turn off 4G dial-up and then observe if there is still a dead reboot.</li>
<li>Turn off WIFI enable and then observe if there is still a dead reboot.</li>
</ul>
<h4>5、Check the device conditional shutdown/restart settings</h4>
<ul>
<li>Check whether the device <strong>SYSTEM SETUP-Power-Low Power Off</strong> is on and whether the current system voltage is unstable and below the set low voltage shutdown value.</li>
</ul>

<ul>
<li>Check that the device <strong>SYSTEM SETUP-Power-Power Mode</strong> is set to timer mode and that the current time is not at the power-on time.</li>
</ul>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=e1c05ac5534747bfebe2ab357d069dc1" alt="" /></p>
<ul>
<li>Check that the device <strong>MAINTION-Power-Auto Reboot</strong> is on and that the scheduled maintenance time is set.</li>
</ul>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=fbbb748ee1f34e493972d23b72f7d811" alt="" /></p>
<h4>6、Check the power of the power adapter</h4>
<ul>
<li>Check whether the power supply video its power to meet the working requirements of the equipment as well as the load, if the power supply is insufficient, the equipment will repeatedly restart.</li>
</ul>
