press the Power button on the indicator panel topower it back on.The library begins to boot up. A library with onlya few drives usually will be fully powered on andready for use within 10 minutes. However, if alibrary is large with a high number of drives, itcan take more than an hour for the library to fullypower on, complete its discovery process, andbecome ready for use. During the power onprocess, the Robotics Enabled indicator flashes.When the library is fully powered on and readyto receive commands, the Robotics Enabledindicator turns solid green.
