ABSTRACT:
Modules coupled to multiple connectors can check to see if full connectivity is provided through the connectors. If it is not, for instance because the connectors are mis-seated, the modules can prevent themselves from fully powering up. In a storage environment, a first module is coupled to connectors. The connectors are coupled to corresponding disk drives. Each connector provides a connectivity indication. The module prevents itself from fully powering up if it fails to receive a connectivity indication from a subset of connectors coupled to boot disks.
