Chapter 3: Subsystem Monitoring 

 

The BBU module has an LED on its faceplate. (See Figure 3-5) The 

function is the same as the similar 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 charging. If the LED is 

illuminating amber, the BBU may have lost its ability to hold electrical 

charge. You should then contact your vendor to verify the problem.  

 

 

Each PSU comes with a single LED at the back (see Figure 3-6), located 

close to the power switch that turns on the subsystem. This LED indicates 

the operational status of the PSU module. Please refer to the PSU LED 

definitions shown in Table 3-6. 

 

The power supply has not been turned on. The PSU 

module LED will blink when the subsystem is 

connected to a power source but not yet turned on. 

The PSU is operating normally and experiencing no 

problem. 

The PSU has failed and is unable to provide power to 

the subsystem. 

The PSU is not turned on and the power cord is 

disconnected.
