511026 Rev. 07-01-19 1036.16 Controlling the UID LEDsThe UID (Unit Identification) LED refers to blue LEDs on the tape library that assist users and servicepersonnel in determining which component requires attention.UID LEDs can be found on the controller board of each base and expansion module. Additionally, thereis one UID LED on the Operator Control Panel OCP. Control of this LED is linked to the base controllerUID LED (i.e. if the base controller is selected and its UID LED is switched on, the OCP UID LED will beswitched on as well).To use UID, navigate to Maintenance > UID LED Control.1. Expand the Component Module list, if necessary, by clicking the down arrow next to ComponentController.2. Select the desired module.3. Click the Switch LEDs On button (or the Switch LEDs Off button to turn off any UID LED)6.17 Moving the Robotic Assembly to the Base ModuleBefore removing a module from the rack, the robotic assembly must return to the Base Module. Undernormal circumstances, when the library is powered off using the front power button the robotautomatically parks and locks into the Base Module behind the OCP. After powering off the library andbefore proceeding with removing a module from the rack, look inside the upper or lower expansionmodule windows to verify that the robotic assembly is behind the OCP.If the library did not move the robotic assembly to the base module, you can do so from the Maintenance> Move Robotic to Base Library screen.
