SentinelRAID 170 Installation and Hardware Reference Manual

Controller monitoring is a necessary part of controller management. If failure events or other disruptive events are detected and reported, controller managers must take the appropriate action to rectify the problem. Failure to act in a properly specified manner to a system event (like overheating) can cause severe and permanent damage to the controller.

The front panel LCD panel comes with three status-indicating LEDs. The LEDs on the front panel are marked, from top to bottom, PWR, BUSY and ATTEN, as shown in Figure 3-1below. The definitions of these LEDs are shown in Table 3-1.
