This allows UPS'ing the central switch only, while knowing they will all stay up.In some cases, that's not always a great idea. Consider the situation whereby a remote "site" served by a remote switch has two or more network devices that rely on another in a local fashion... such as in the case of a NAS or SAN serving a local workgroup of machines. If you have to take down the central switch for whatever reason then you cut power to the remote switch and all the associated end-station lose local network connectivity as well. Of course you can always resort to manually plugging in the remote switches. Can those GS108T-200 perform auto-cutover to AC power? That would be ideal.
Of course, if he had local AC power available, it would kinda defeat one of the points of having PoE, which is to be able to put switches where there isn't a convenient AC drop to begin with. ^_^; Matt
