Adding Plug-ins
For optimal operation, the hub and all of the spoke servers should have the same version of a
plug-in installed. Follow the steps described in Recommended Sequence for Adding/Upgrading
Plug-ins on page 291.
During the add operation on the hub server, new data types defined in the plug-in are registered
in the Rack Power Manager software database. After the plug-in is added to the spoke server
and a replication operation is initiated, the registration information on the hub server is
propagated to the spoke server.
On the hub server, a new plug-in becomes active when it is added. On a spoke server, a new
plug-in becomes active only after the plug-in is added to the hub and then to the spoke and a
subsequent replication completes successfully.
For some plug-ins, you may need to add a license key to the Rack Power Manager software
system before adding the plug-in to any server. See the documentation included with the plug-
in or contact your Emerson representative to determine if a key is needed. To add a license, see
Licenses on page 58.
