Chapter 5: Subsystem Maintenance and Upgrading
Figure 5-7: Install the BBU Module
Step 3. Secure the BBU module to the enclosure. Tighten the two (2) retention screws as shown above using a Phillips screwdriver.
Step 4. Reset the subsystem. Find appropriate time to reset the subsystem for the subsystem firmware to recognize the replacement module. After reset, the BBU LED will start flashing to indicate that the BBU is being charged. When the BBU is fully charged, the LED will be off.
NOTE:
1.A new or replacement BBU takes approximately seven (7) hours to charge to its full capacity. Reset the subsystem whenever a BBU is replaced or added in order for the replacement module to take effect.
2.The life expectancy of a BBU is more than one year. However, it is considered a safe procedure to replace the BBU every year. Follow the procedures above to replace a used BBU with a replacement in order to maintain the fault tolerance feature.
3.The chance of BBU charger failure is comparatively low. If the cause of a failure cannot be determined even after a BBU module is replaced, contact your system vendor for a replacement controller and return the controller module through EMD’s standard RMA procedure.
