I acquired two new R1500XR ups with the 6-port option card (192185-B21) to replace two older, fried boxes. While the power supply itself works satisfyingly I am not at all able to communicate with the ups through the 6-port cards.
Currently I am working on just one of the upses; on this box, only one server (Win NT 4.0)is installed with cable from COM1 to Port 2. The server was previously installed with the Lansoft Power Monitor; when the new ups was connected the monitor went yellow and reported 'communication errow with ups'. I have since tried reinstalling the LPM, installing the Compaq PM, installing the HP PM, and installing the HPRM. At the moment, I am running Compaq Power manager 1.81 for NT. Also installed on the server is Compaq Insight Manager.
Each time, after restarting the monitor service, the monitor goes yellow with the same message as before. I have tried Port 1 and tried the other COM-port on the server, but still no contact has been achieved. I am using the communication cables supplied with the card and have also tried the cables supplied with the previous ups, with no positive effect. The cable is well attached. Please advice as to what I should do next.
