=====APCUSPd CentOS 6.5=====
This guide will let you configure apcupsd using PCNET broadcasts from the UPS network management card.
Prerequisites:
* EPEL repo
* APC UPS with network management card 2, firmware 6.1.1.
====Configure APC network management card to allow PCNET connection====
PCNET is UDP broadcast communication over port 3052. If you use a firewall, open communication for this port.
* Configuration -> Shutdown, disable Basic Signaling Shutdown.
* Configuration -> Shutdown, enter 16 character shutdown phrase.
* Configuration -> Shutdown, username: device.
* Configuration -> PowerChute clients -> add client IP address.
====Install and configure apcupsd====
* Install apcupsd. yum install apcupsd
* Autostart apcupsd after boot. chkconfig apcupsd on
* Configure apcupsd. Edit **/etc/apcupsd/apcupsd.conf**. UPSNAME SMART750
UPSCABLE ether
UPSTYPE pcnet
DEVICE 1.2.3.4:apc:1234567890123456 # Your 16 char shutdown phrase.
BATTERYLEVEL 10 # Issue shutdown at or below 10% battery.
MINUTES 10 # If runtime left is 10 minutes or below, shutdown.
* Open UDP 3052 from UPS to server. Edit **/etc/sysconfig/iptables** -A INPUT -m state --state NEW -m udp -p udp --dport 3052 -j ACCEPT
* Restart iptables. service iptables restart
* SELinux: Allow bind to port 3052. This should be fixed in newer versions of CentOS. yum -y install policycoreutils-python
