Issue Details

After connecting a cDAQ-9189 chassis to my network switch, the port appears to be unsusable, it can be either blocked or damaged after the connection. There are other devices working correctly while connected to it, and those ports were working properly before the connection.


The cDAQ-9189 chassis has 2 Ethernet ports and can be connected in daisy-chain, as you can see in Chapter 2 of the User's Manual (see related links for the link to this manual). It also states that the cDAQ-9189 has an internal Ethernet switch. The reason why the ports are being blocked may be because the network switch is configured to do this when unmanaged switches are connected to it, and for the characteristics mentioned before, it is considering the 9189 as one of these. To fix this, you need to contact your IT department so they can get the connection working, by giving permissions for this device to be connected, or any action they need to take in order to enable a port for that connection.
