I sent the message below to the UPS mailing list, but it's a pretty slow list, so I thought I'd see if anyone on WLUG might have an idea. I'm beginning to suspect a serial line configuration issue. Any ideas? Thanks, Bill Mills-Curran ---------- Forwarded message ---------- Date: Mon, 3 Jun 2002 08:29:56 -0400 (EDT) To: Ups mailing list <ups@lists.exploits.org> Subject: monitoring a Matrix 3000 Hi, I've installed the nut rpm's from the RedHat 7.2 distribution: nut-cgi-0.45.0-3 nut-0.45.0-3 nut-client-0.45.0-3 I am attempting to monitor the state of 2 APC Matrix UPS's; a model 3000 and a model 5000. I have two different sets of cables to work with; 940-0020B and 940-0024C. In short, I can't get any indication of communication between my linux box and the UPS. I've looked through the FAQ's and other documentation pretty carefully, but I must be missing something. Any direction anyone can give would be appreciated. Documentation for these UPS's can be found at: http://sturgeon.apcc.com/techref.nsf/docID/3BF5FC2524F090888525675200631528/... There's a description of the pinouts on p. 39. **************** Basic setup: I have a couple of racks of inter-dependent equipment powered from 2 UPS's. The interdependence forces me to shut down all machines before either UPS fails. I plan to use a single linux box to monitor the state of the UPS's and to send shutdown signals (via small private network) to the servers when the battery gets low. The linux box is old hardware, but the linux software installation is new. In an effort to simplify the problem, I've dropped back to monitoring a single UPS. Below are the config files and results for using the two different cable types. For both config's, I set the permissions on /dev/ttyS0 to 666. **************** Using the 940-0020B cables.
