The light path diagnostics panel is located on the top of the operator information panel.
To access the light path diagnostics panel, slide the blue release latch on the operator panel to the left. Pull forward on the panel until the hinge of the operator panel is free of the server chassis. Then pull down on the panel, so that you can view the light path diagnostics panel information.
By placing the system-error LED indicator in Remind mode, you acknowledge that you are aware of the last failure but will not take immediate action to correct the problem. The remind function is controlled by the IMM.
