Andre,
You may want to try using HP Power Manager ver. 4.0 (
www.hp.com/products/ups under software). The software supports Windows, RH Linux, and HP-UX 11x. As long as your HP9000 servers can run HP-UX 11i and have a NIC, it can be done. As far as setting the 4 servers up for the power protection, you may either pick one server to be your Management server and the other 3 have Remote Agents installed. The Management server machine has "direct connection" (via either serial interface using existing serial card on the UPS or network using the SNMP/Serial card you mentioned) to the UPS. It will constantly monitor the UPS status and if needed, it will send shutdown commands to the other servers to shutdown as well as it will shutdown itself upon a power failure event. Also, the Management server piece could be on a 5th machine and then you will need to install Remote Agents on 4 of your servers. In any configurations I mentioned, all machines must be on the same network to be able to communicate to each other. The Six port card will not help in this case since you can only connect 3 servers to the card directly.
Thanks,
Steve
