You activate it on both sides and that's it. It does not need a pair of devices. > Another question: Is it necessary to regularily check if the ISLINK is up or > is the system trying to reactivate a link? If the other system went away, CP still has the link active and picks up when its friend is back. If you put the ACTIVATE somewhere in the startup of the system, things tend to work just fine. If you run PROP, then PROPCHK can do a periodic availability check. If you also run RSCS you can issue the remote command to start the link if you need. This is more relevant when you have >3 systems connected and want specific links to be active during an outage of one of the systems. Rob
