Hp ups serial cable

I have had a R for several years and it refuses to connect anymore. Perhaps i need a new cable too. I doubt that a serial cable would just 'break down', unless there really are some ICs or resistors in the cable, and even then, the chance is reasonably small. According to the documentation in the user manual at least for my R it states that one shouldn't connect a 'regular' serial cable, as this can damage the equipment, though it also states that it's a 'standard RS' connection.

Do you by any chance have the possibility of testing a different add-in card? Does the UPS behave normally apart from the 'no serial connection' issue? Also, I've found a couple of sketchy pinouts for my model on the regular HP user forums. You might wanna give one a try:. I have the serial that came with the R, it worked for a while. So I am starting to wonder if I changed the port some time ago and forgot what I used. Is there anyway to reset the config?

I'm sorry, maybe I' having a delayed case of the Mondays here, but how do you mean 'configured the port'? As far as I'm aware the RS port has a fixed configuration of if I remember correctly at baud.

You referred to a 'port ', which would lead me to believe you're referring to a TCP? I checked for the 'reset' function, but I can't seem to find one. I opened my UPS and had a look inside before installing it in the rack, and wouldn't be surprised if the device loses its settings when the battery is disconnected and no auxiliary mains power is connected, but I could be wrong.

Some of these enterprise devices simply don't feature the 'reset to factory defaults' option often found on consumer devices.

Just an idea, but have you tried powering down the UPS and disconnecting it from the mains , removing the serial add-in card, starting up again, then placing the card in the unit again while switched off! It might just 'lose' its settings for the port, or reconfigure them with the default values from scratch when it finds the card again I have already switched it from on server to another that is on the UPs to no avail.

Do they require a special card? When I right mouse click on the taskbar icon with the red X that says no device, i have a choice of connect, Stop Service, Start Sevice checked , confiure and Exit. Below is what comes up if I select configure:. Uhhm, the software you're using is for connecting to the 'agent' running a computer connected via a serial cable to the device. As far as I am aware, these devices do not feature a webserver.

The agent performs this task by communicating with the UPS via serial connection, and offering the data in a web based interface. These settings must match the settings specified in the documentation for the device. If the agent is started, it might make a log somewhere I haven't got around to installing it yet myself, and I was planning on using the Linux version, anyway.
