Connection Failure

This question was originally posted on DCIM Support by John Beck on 2018-09-10


Trying to discover an APC UPS (16kVA Symmetra LX) and keep getting Connection Failure.  I have already successfully discovered twenty-sixe (26) APC UPS's.  

Does IPv6 need to be Enabled or not?

Dear John Beck,

IPv6 does not need to be enabled (unless it is a standard on your network).

Please, share a few screenshots where we will clearly see how you are discovering this type of equipment (16kVA Symmetra LX) in the EcoStruxure IT Gateway software.

With respect.

I mean a screenshot of the Device Discovery web-page, as, for example, you can see it in instruction Installing and setting up EcoStruxure IT Gateway.

Dear John Beck,

Thanks for the detailed information.

First you need to go to the web-GUI of this problematic UPS and make sure that the SNMP v1 protocol in its network settings is enabled. In addition, there you also need to make sure the Read community and Write community strings are correct. This is also important.

With respect.

The READ and WRITE Community Strings are correct. There is a 16kVA Symmetra LX UPS in the rack next to this one. It is called VE012UP1 with an IP Address of 10.48.6.48 and it is working fine and it connected to EcoStruxure IT with no problems. I have been comparing settings on the Network Management Cards of both of these and I can't see any difference.

Dear John Beck,

Ok, for comparison, please make use of the already known PortQuery command for the request of the two above mentioned UPSs (10.48.6.46 and 10.48.6.48) using the SNMP (UDP) protocol as in the screenshot:

If it's okay, you should see something like this UDP port 161 is LISTENING.

What will you receive in return? You will have only two options: either it is a network problem (firewall, for example) or it is the NMC problem of your UPS...

With respect.

Why doe the one that has connected (VE012UP1 - 10.48.6.48) say "FILTERED"?   And the one that doesn't connect (VE011UP1 - 10.48.6.46) say "LISTENING"?

Now, please check both UPS's web-page Configure SNMPv1 Access Control through the web-GUI (Configuration -> Network -> SNMPv1 -> Access Control).

Compare both web-pages, whether everything is the same?

I.e., if on both UPS's Read community string = EHITro, then exact this string you need paste in doscovery dialog gateway software. This is first.

Secondly, for all native Schneider Electric devices Write community string must be enabled (Write+). This is necessary for priority scanning, i.e. for operational allerting. Since you have shown in the screenshot, this option will not work.

With respect.

Is there something going on with the EcoStruxure IT Gateway?  I now have 26 devices (UPS's) not responding.

See my comment about Write community string. Additionaly, please check the UPS's web-pages Configuration -> Network -> FTP server and Configuration -> Security -> Firewall -> Configuration. FTP server must be enabled and Firewall must be disabled.

From your comment:

Maybe you have a change in the network or on the firewall? Check the log files on your UPS. What can be seen, can a network flood or something else?..

With respect.

This is good, but the Access Type for private Community Name must be definitely Write+. This requirement of EcoStruxure IT Gateway software is important.

If you are worried about security, then allow private Community Name only for the IP address of your server with the gateway software (NMS IP/Host Name).

With respect.

The twenty-six (26) UPS's we have that have connected to EcoStruxure IT Gateway (but not at the moment) have "private" "public2" and "private2" ALL with Access Type of "Disabled".

Also, I have the EcoStruxure IT Gateway installed on my work laptop, this means that when I leave work and my laptop is shut off the Gateway is also. Should I have the EcoStruxure IT Gateway installed on a standalone server (Physical or Virtual)?

Dear John Beck,

From your comments:

...Should I have the EcoStruxure IT Gateway installed on a standalone server (Physical or Virtual)?

Yes, of course. This is the only way to do it, otherwise I do not see the point in this all.

After all, when you shut off your working laptop, the entire connected system of your UPS's, your gateway software, the network, the SE cloud servers and your mobile app falls into one big mistake 😀.

More details about the system requirements for the gateway server hardware operating in 24/7 mode can be found in topic System requirements:

Server
  • A server, or a PC that is always on, with Microsoft® Windows® 7 64-bit, Windows 2008 R2 SP1 64-bit or greater operating system
  • At least 2 core and 4GB of RAM
  • 2GB hard disk space

EcoStruxure IT Gateway was tested on Microsoft Windows Server 2008 R2 SP1, Server 2012 SP1, and Server 2016.

The application takes 225MB of disk space, and the server retains a maximum of 8 days of data, about 128MB per day.

Scale for small, medium, and large installations
Size
Number of devices
Number of sensors
RAM
CPU
Size on disk
Small 250 34,000 4GB 2 128MB per day
Medium 2000 270,000 8GB 8 512MB per day
Large 5000 540,000 16GB 24 1.1GB per day

_

Firewall
  • Port 443 TCP outbound
  • To connect using static IPs, add 40.84.62.190 and 23.99.90.28

If you have any more questions, please ask.

With respect.
