have FOUND SOME MORE DATA, but still leaves questions. My data on the right from Sola manual Make Bergman wrote re the HP unit: "For Windows NT 4.0+and HP-UX or compatible UNIX systems, use SNMP via the HP PowerTrust II-LR A1359A SNMP/Web Adapter. SOLA docos give: DB-9 Pinouts Pin 1 RS232 Receive Data level shutdown - +12V for 5 sec shuts down the Sola - see pin 7 Receives incoming RS232 communication data. Pin 2 RS232 Transmit Data unused Sends outgoing RS232 communication data. Pin 3 Normally Open On-Battery Contact same spec A normally open contact that closes 15 seconds (pulls to Common) after the UPS switches to battery power. Pin 4 Common same spec The signal ground for all signal pins. Pin 5 Normally Open Low-Battery-Alarm Contact same spec A normally open contact that closes (pulls to Common) during a Low Battery Alarm. This tells CheckUPS II and other shutdown software when to start a computer shutdown. Pin 6 Reserved. Normally closed low batt, opens during low batt alarm Pin 7 Remote Shutdown unused, see pin 1 above Shorting this pin to common for at least 5 seconds, while the UPS is operating on battery, shuts the UPS off after 120 seconds. NOTE: The shutdown sequence must continue even if AC line returns during the 120 second countdown. Pin 8 Normally Closed On-Battery Contact normally closed, opens 15 secs after going to battery A normally closed contact that opens (releases from Common) 15 seconds after the UPS switches to battery power. Pin 9 Normally open bypass switch status contact. = unused A normally open contact that closes (pulls to common) whenever the UPS is in an Internal Bypass mode or is being externally bypassed through the use of a bypass switch. Anybody been here before, knows how to pin a cable to mate a Sola to an N series DB9, and a 928 DB25 modem port please? thanks, John Pitman * To join/leave the list, search archives, change list settings, * * etc., please visit http://raven.utc.edu/archives/hp3000-l.html *
