It will do just about anything you need, though it is a bitch to set up (umpteen interrelated config files need to be just right). But more importantly, it has lots of good documentation about cables and such. I found, for example, that the supposedly correct APC cable for my APC BackUPS (one of the semi-dumb ones) was actually missing a line. I made a custom cable, and walla! no more problem. Keep in mind, by the way, that the serial cable is not actually sending serial data (like ascii text, for example). It just raises and lowers the levels of various lines to signal various things. (I know you probably already know that, but just for completeness...) And finally, yes, even the dumb UPS's can sense and communicate the loss and return of AC power, at the very least.

There are two classes - "smart" and "dumb" as far as I know. So, before buying and one wants to have full bi-directional functionality, make sure it has the capability. Don't just go by "it has a cable" and let the cable fool you otherwise. Unfortunately, I have never seen a box that explained this on the outside or even the inside of a "dumb" one -- with cable.

The computer gets three signals: On battery power, off battery power, and almost out of battery. The computer can send one signal to the UPS, telling it to turn off and stay off. The idea is that you use the last signal from the UPS to initiate a shutdown, and the last thing you do as you shut down is tell the UPS to go off and stay off. I have as yet to figure out how to get FreeBSD to signal the UPS to shut down in a safe way. Anyone else worked on this one?

Stone, > Administrator Thanks for the replies, guys; I really appreciate it. :) The BackUPS 350 CS is not supposed to be truly 'dumb', but allegedly can report power-failure over its cable. So, I ran "apctest", and a line change of sorts IS noted: -- 2003-01-20 11:32:31 apctest 3.8.5 (4 January 2002) freebsd Checking configuration ...

Select test number: 3 For the third test, the serial cable should be plugged back into the UPS, but the AC power plug to the UPS should be DISCONNECTED.

Re: Shutdown for APC Back-UPS 350 CS
To do what you want requires a UPS with "SmartUPS" to "talk" to your system. You have what is referred to as a "dumb UPS". I use SmartUPSes on "master" machines to tell the "slave" machines when to shut down and other instructions. The SmartUPSes will carry on an exchange with the machine, but the dumb ones will not. The slaves are attached to the dumb UPSes for continuations of power, but the SmartUPS tells each slave what to do and when to shut down. Each slave must have an apcupsd daemon installed, running and configured to communicate with the master over the network for this to work. But why then supply a cable for use between the 350CS and the computer? I use only SmartUPS and BackUPS Pro so I could not be sure but...

Yes, I have the correct cable; in fact, APC specifically sent it to me as I could not get USB to work at all (seems not yet supported on FreeBSD), and the number is stamped in the cable. I am familiar with the document you pointed me to, and I believe I set everything according to how it should be; here is my config (stripped off comments): UPSCABLE 940-0128A UPSTYPE backups DEVICE /dev/ttyd0 LOCKFILE /var/spool/lock BATTERYLEVEL 10 MINUTES 3 TIMEOUT 15 ANNOY 10 ANNOYDELAY 5 NOLOGON always KILLDELAY 0 NETSERVER off NISPORT 7000 EVENTSFILE /var/log/apcupsd.events STATTIME 3600 STATFILE /var/log/apcupsd.status LOGSTATS off DATATIME 0 UPSNAME UPS_IDEN BEEPSTATE 0 LOWBATT 2 UPSCLASS standalone UPSMODE disable NETACCESS true Understanding the docs right, the "TIMEOUT 15" should start a forced shutdown after 15 secs of power loss (set so low for test-purposes). Alas, nothing happens. :( Thanks anyway. - Mark To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
