4.2.5 BBU Module LED
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.
