Connecting a UPS to your Linkstation

Installing Network UPS Tools (nut)

Prerequisites

Install the 2.6 kernel to get the new USB HID modules http://linkstationwiki.net/index.php?title=Category:Kernel

Setup your system to accept packages from the unstable branch (follow instructions for everything except the last step to "apt-get -t install xyz" ) http://www.linkstationwiki.net/index.php?title=Get_access_to_packages_from_the_Debian_unstable_branch#Unstable_Packages

Fix your localhost entry if applicable. This is a current bug with freelink 1.11 HG:

Modify /etc/hosts This line:

127.0.0.1 Linkstation

to

127.0.0.1 Linkstation localhost

if there was "127.0.0.1 localhost", this is good already, no need to change it.

Installing

apt-get -t unstable install nut nut-usb

which will also add the appropriate lib-usb. and install nut & nut-usb 2.0.4-2 or better

Config files setup

Now that you've installed nut, you must set it up. Follow instructions under /usr/share/doc/nut/README.Debian or use this quick and dry way:

cd /etc/nut/
cp  /usr/share/doc/nut/examples/ups.conf .
cp  /usr/share/doc/nut/examples/upsd.conf .
cp  /usr/share/doc/nut/examples/upsmon.conf .
cp  /usr/share/doc/nut/examples/upsd.users .
chown nut:nut *
chmod 600 *

Edit ups.conf

Add this anywhere inside the file:

[myups]
       driver = newhidups
       port = auto
       pollinterval = 10
       desc = "My APC 1000 UPS":

Edit upsd.users

Add this anywhere inside the file:

[monuser]
       password  = blah
       allowfrom = localhost
       actions   = SET
       upsmon master

blah is the password you wish to use. Make sure you use the same one in upsmon.conf

Edit upsmon.conf

Add this line:

MONITOR myups@localhost 1 monuser blah master

blah is the password you wish to use. Make sure you use the same one in upsd.users

Edit /etc/default/nut

Modify the first few lines to:

# start upsd
START_UPSD=yes

# start upsmon
START_UPSMON=yes

Issue a reboot

to load the newhisups driver, upsd and upsmon

reboot

Verify UPS connectivity

Basic connectivity

newhidups -u root -D -D -a apc

You should see your UPS information showing up.

tail -1000 /var/log/syslog |grep ups

You should see something like this: Aug 11 15:31:38 LinkStation newhidups[1606]: Startup successful Aug 11 15:31:38 LinkStation upsd[1607]: Connected to UPS [myups]: newhidups-auto Aug 11 15:31:38 LinkStation upsd[1608]: Startup successful Aug 11 15:31:38 LinkStation upsmon[1610]: Startup successful Aug 11 15:31:38 LinkStation upsd[1608]: Connection from 127.0.0.1 Aug 11 15:31:38 LinkStation upsd[1608]: Client monuser@127.0.0.1 logged into UPS [myups]

Power outage detection

If this all works, try removing power from your UPS to verify id the Linkstation will detect it. You should see this in your syslogs, again using

tail -1000 /var/log/syslog |grep ups

Aug 10 15:59:28 LinkStation upsmon[1613]: UPS myups@localhost on battery

Aug 10 16:04:39 LinkStation upsmon[1613]: UPS myups@localhost on line power
