Configurazione di un UPS

Collegare l'ups seriale su COM1 (/dev/ttyS0)

Installare il software di gestione

apt-get install apcupsd

Verificare la porta a cui si è collegato l'UPS

L'elenco delle porte seriali lo si può ottenere con:

dmesg | grep ttyS

Si ricorda che:

COM1=ttyS0
COM2=ttyS1

Nel caso si correga nel file /etc/apcupsd/apcupsd.conf:

DEVICE /dev/ttyS0

Testare la comunicazione con l'ups:

apctest
