Q. What is the purpose of the "Dialect" parameter in the IPMI probe?
A. The IPMI probe has a parameter, "Dialect", which you can set to "XServe" or "Other". Set it to "XServe" if you are targeting an XServer, and set it to "Other" for anything else. This is necessary due to some minor differences in the IPMI protocol implementation on XServes vs other implementations.
Note: The new XServe's (2009) need to use the dialect of "Other".
