The BBU module has an LED on its faceplate. (See Figure 4.4) The function is the same as the 

fifth LED on the controller module. The LED is off when the BBU is functioning normally and is 

able to sustain the cache memory. The LED flashes to indicate the BBU is currently charging 

its battery cells. If the LED is illuminating amber, the unit may have failed. Please contact your 

system vendor to verify the problem.

PSU LED

Each PSU comes with a single LED located just above the power switch and just below the 

retention screw (see Figure 4.5). The LED is used to indicate the operational status of the PSU 

module. Please refer to the PSU LED definitions shown in Table 4.5.

The LCD panel located on the front aluminum foldable handle comes with three status LEDs. 

The LEDs are marked from top to bottom “PWR,” “BUSY” and “ATTEN” and are clearly seen in 

Figure 4.6 below. The definitions of these LEDs are shown in Table 4.6. The mute button can 

be used to stop the alarm until the next controller event occurs.
