Hi All,

I have configured cooling system on DCO. There is Uniflair Crah that have only Modbus TCP communication protocol.  So i manualy gave Crah supply and measured return temp. on Crah. When i gave the those value i have seen so big values as you can se attached values. What is that reason? Please can you advice me how can i configure Crah without SNMP protocol.

Thanks

Hi Kerem,

If you're looking to add the unit to StruxureWare Data Center Expert and in turn have DataCenter Operation pick up thee values from there, DCE is capable of monitoring not only SNMP devices but Modbus over IP devices as well. You will want to first contact Multivendorsupport@apcc.com if you do not have the proper DDF for your device. Once you receive the DDF, you simply add that DDF to the DCE server then discover that device telling the DCE server the IP, slave address, and DDF to use for discovery. You should now have the values in DCE.

Assuming your DCO server is communicating with this DCE server, you should be able to see that device and associate it with the device in the DCO model.

Thanks,

Steve

Hi Kerem,

In continuation to the point that Steve has made above please see a dedicated section I created for similar Building side Integration and what all you need to look out for.

Hi Kerem (kerem.yilmaz)

According to your screen capture, I believe you have basically some configuration issues and clearly the cooling calculator is not working correctly and complaining about the Invalid temperatures!

• I would suggest checking if the containment system is properly setup (and racks are completely placed inside it).
• And for the manually entered CRAC temperatures, I would suggest to leave the "Measured Return Temperature" filed empty, and let the software do the cooling calculations.

Hope this helps,

Kind regards

Thanks for advice Jef, I will apply your suggestions. By the way, i have 5 cold aisle all of them is looking good and estimate normaly without any err message exept one cold aisle. That cold aisle says"System can not compute :" as you can see in attach. I tried so mant times for changing and compute but i have not succeded. Do you prefer any way to compure corretly. One more, how can i cahage the crack temperature threshold level ? Regards Kerem

Hi Kerem, You are welcome, Please take a look at the following image, it is actually your screen capture, where I have highlighted the notifications concerning why "the system cannot compute". ( 1_capture.JPG ) It says: a) The containment system has gaps. Basically you might need to remove the empty space between the racks. In this case you have only half full container, so you might want to use "block" (or similar), as a work-around, to replace the large empty space/gaps in the containment system. b) The containment system must snap to equipment in the ends. Apparently racks are not correctly placed inside the containment system (specially in the ends), small adjustments seems to be needed. To change the cooling temperature threshold, right click on floor > Properties > Cooling, and then change/set your "Cooler supply" temperature. illustrated in 2_cooler-supply.JPG Hope this helps, Kind regards --
