====== UNIFI ======

===== US-48-G1 =====

  * V zarizeni jsou potize s vetrakem. Jedna se o SW problem, jde vyresit skriptem:

<code>/etc/persistent/fan-override</code>
<file name=/etc/persistent/fan-override>
#!/usr/bin/sh
MAX_TMP=50
WAIT_TIME=300

while true
do
        GET_TMP1=$(swctrl env show | grep TEMP-1 | awk '{print $2}')
        if [ $MAX_TMP -lt "$GET_TMP1" ]
        then
                echo "TMP1 = ${GET_TMP1}"
                echo "High Temperature detected, turning fans ON."
                swctrl fan diagnostic
        else
                echo "TMP1 = ${GET_TMP1}"
                echo "Temp below threshold. All good."
        fi
        sleep ${WAIT_TIME}
done
</file>
<code>/etc/persistent/rc.poststart</code>
<file name=/etc/persistent/rc.poststart>
#!/usr/bin/sh
/etc/persistent/fan-override &

</file>

**V Unifi switchi aktualne nefunguji poststart skripty tj. je potreba si pomoci pres profile, aby se skript spustil alespon po kliknuti na debug console v unifi controleru**
<code>/etc/persistent/profile</code>
<file name=/etc/persistent/profile>
#!/usr/bin/sh
/etc/persistent/fan-override &
 
</file>

  * Skript je napr mozne spustit pres  nejaky monitorovaci nastroj, ktery detekuje pres SNMP restart zarideni apod. Moznosti je vice, ale je to opruz. UBNT by mohlo tento problem konecne vyresit, nebo aspon umoznit spousteni skriptu po startu zarizeni.

Nakonec je potreba zavolat prikaz, aby se nastaveni ulozilo a prezilo pristi reboot
<code>
chmod +x fan-override rc.poststart profile
save
</code>
