Onboard Administrator supports three topology modes which are determined by the selection made on the sign in screen prior to signing in. The three topology modes are:
- Local Mode—Used to manage a single enclosure when more than one enclosure can be selected. Onboard Administrator ignores all topology changes. This mode is useful when you do not want to change topology by adding linked enclosures.
- Linked Mode—Used to manage a single enclosure when no other enclosures are attached. You can use Linked Mode to allow the addition of new enclosures as they are added to the interlink. As long as no new enclosures are connected, Onboard Administrator appears to be in Local Mode. All topology changes that occur while signed in are displayed by Onboard Administrator. This mode provides an unrestricted view of enclosures connected to the interlink.
- Fixed Mode—Used to manage more than one, but not all enclosures. Only the topology changes affecting the current topology are displayed by Onboard Administrator. This mode is useful when monitoring a subset of the total enclosures connected to the interlink.
If the active mode is set for a single enclosure and one or more enclosures are connected, if you want to ensure that the additional enclosures are not visible in the enclosure topology, you must sign out and back in without selecting a linked enclosure.
