RDU alarm set point in DCE

[DCIM_Support]

We have DCE 7.3.1.  There are 2 RDU in a room that is connected to DCE.  The problem right now is that we don't have enough of a load to keep the RDU's busy enough.  As a result, we are getting a "RDU:  Condensing temperature high violation exists." alarm, which clears and then returns.  How can I adjust the alarm point to reduce the alarms?  Also, can a reminder be established on the alarm set point to reset it back to default at some time in the future?

Thanks.

Hi Michael,

There are 2 different thresholds that could be set here.You could have a manual threshold set in DCE specifically or, if you have not created one in DCE, you would have a device threshold on the PDUs themselves.

the way you're explaining it, I'm assuming it's on the PDU so there are again 2 ways to configure them. Since there are only 2, you could log into each device and manually change the threshold. You would go to the environmental page (this is a screenshot of a 6.x firmware)

choose configure, then edit the appropriate settings

If you want to configure the device's threshold via DCE, you would want to go to device->APC SNMP device configuration:

Choose standard device configuration settings.

Choose configure device:

Select a configuration source (I'd choose the PDU you're using):

If no configuration has been retrieved, select retrieve device settings, then next.

Now select the units you want to configure and hit next. 

Under advanced settings, look for sensor:

For temp, you'd set the SENSOR_TEMP_ALARM_THRESHOLD_A

Please note that here the 2 thresholds are listed as 140 and 138 while on the device it was 60 and 59. The device was set for Celsius while DCE is showing in Fahrenheit. 

For 2 units though, it may just be easier to do it directly on the device.

There is no specific reminder alarm that you can pop up.

Thanks,

Steve

Hi Steven,

Thanks for your answer, but the alarms are actually coming from an APC RDU (Refrigerant Distribution Unit)  (not a PDU), which is part of the InRow cooling system.

Thanks for your update Steven. I think I understand, but I'm having a problem identifying what needs to be changed to modifying the DCE alarms. Wondering if you or someone else can help me out. Thanks

Hi Michael,

sorry i misread RDU as PDU. I'm not as familiar with the RDU but if it is a threshold, your options would be similar. You can change thresholds through the unit or similar DCE menus.   

If it is not a threshold on the device and still an alarm, you can put the device into maintenance mode so all alarms will not be sent through DCE or you can just disable the alarm. 

Again, sorry for the misunderstanding. 

Steve.

Hi Michael, If you need someone on the phone, you can contact technical support and if need be (and if allowed), they can remotely access your system and assist in troubleshooting of figuring out exactly what needs to be done. As for the specific issue, as I mentioned you can right click the device and put it into maintenance mode and no events at all should be sent from DCE. You can also click the alarm configuration tab, device alarm configurations, find the unit(s) in question on the left in the default layout, then find the message on the right that matches the error. You can then edit that alarm and disable it. Again, you'll have to manually re-enable it. As for the device itself, I don't have one available and not knowing the device itself, I can't specifically tell you how to reconfigure the device to reconfigure the sensor if that is possible. If there's someone else on these forums more familiar with the RDU, please feel free to assist Michael with this question. Steve.

Hi Steve, Thank you very much for your assistance. I think that I found the area to disable the alert that I was looking for, per your instructions. I would be nice if I could actually have adjusted the values where the alerts are triggered. As this option did not exist, I disabled the alert for now, and put a reminder in my calendar to look at this in a couple of weeks. Thanks again 🙂
