Replace A Control Module - Dell EqualLogic PS Series Hardware Owner's Manual

PS6610 Hardware Owner's Manual
Using the Standby On/Off button on one member does not affect any other group members, with the
exception of the group lead member. When the group lead member is in standby mode, it takes a few
minutes for the group lead to fail over to another member. You must press the standby button on each
member to restore power to the member that is in standby mode. Group members that do not have the
standby button remain online; to shut them down, you must use the GUI or CLI.
