Note, in this case, we use considerably more configuration options
to ensure that the system files are placed in a different directory
($HOME/apcupsd/bin). We have also selected a different serial port and a
different NIS (Network Information Server) port. And finally, we have used
the --disable-install-distdir option, which prevents make install
from doing the final system installation (i.e. the modification of the halt
script) since this was previously done.
Important Steps after Installation of the Second Copy:
After the make install of the second copy of apcupsd there are a number
important steps to complete. You must either remove or modify the file
$HOME/apcupsd/bin/apccontrol, so that it will not shutdown Computer
A when the battery of UPS 2 is low. One suggestion is to copy exam-
ples/safe.apccontrol into $HOME/apcupsd/bin/apccontrol. Alternatively,
you could edit the $HOME/apcupsd/bin/apccontrol and delete all state-
ments that attempt to shutdown the machine. Another important step is to
find a way to shutdown Computer B when UPS 2’s battery is low. Probably
the simplest way to do this is to edit $HOME/apcupsd/bin/apcupsd.conf
on Computer A so that this second copy of apcupsd becomes a network
master. Then install a standard slave configuration on Computer B. Please
remember that if UPS 1’s batteries are exhausted before UPS 2’s batteries,
Computer B may not be properly shutdown. And at the current time, there
is no simple means to make the two copies of apcupsd running on Com-
puter A communicate. Thus there are certain risks in such a configuration.
However, these configurations can be very useful for powering electronic
equipment and such.
If Computer B is vitally important, it would probably be better to purchase
