FLASHING indicates the batteries are being charged.

Table 3-6: BBU LED Definitions

IMPORTANT!

In addition to BBU failure itself and the charger failure, the subsystem may also light the BBU fault LED when the following occur:

1.The temperature sensor embedded with the charger circuit reports a temperature reading exceeding 45 degree Celsius.

2.The BBU (battery backup unit) has been charged for over 12 hours. The BBU charger will enter a timer fault state.

When the above conditions occur, the charger circuit will enter a low-power and self-protection state.

You may correct the faults when receiving a “BBU Thermal Shutdown/Enter Sleep-Mode!” event message:

1.Check proper ventilation within the subsystem. You may also check the readings from other sensors within the enclosure. Airflow might have been disrupted by the absence of one or several major modules or the failure of a cooling fan. Once the thermal condition is improved, charging will resume automatically.

2.If a new battery module has been charged for over twelve (12) hours and this event is issued, you may remove and re-install the battery module. An empty battery module may take more than 12 hours to be fully charged. There is a timer embedded with the charger, doing so can reset the timer. Charging will resume automatically.

3.Whenever you install/re-install a BBU, the subsystem recognizes a BBU only after a system reset.

3.2.6PSU Module LED

Each PSU module has one (1) LED just below operational status of the PSU module. Please refer to

the retention screw to indicate the Table 3-7for PSU LED definitions.
