3. Secure the BBU to the subsystem by fastening the two (2) retention
screws on the back of the BBU (See Figure 5-9)

4. Once the new BBU is correctly installed into the subsystem, the LED
should start flashing to indicate that BBU is being charged. When the
BBU is fully charged, the LED will light amber constantly.
NOTE:
The life expectancy of a BBU is approximately 500 cycles. Follow the
procedures above to replace an old BBU with a new BBU in order to
maintain fault-tolerant subsystem functionalities.
5.5 Replacing a Faulty PSU Module
5.5.1 PSU Module Overview
• Two (2) redundant PSU modules: The FALCON II is preinstalled
with two (2) 460W, fully redundant, hot-swappable PSU modules.
These modules are located at the rear of the subsystem.
• PSU bracket: Each PSU module is permanently mounted in a two-level
steel bracket, creating a single unit. The PSU is located in the upper
level and a removable cooling module is mounted in the lower level.
When removing the PSU from the subsystem, the cooling module is
also being removed.
• PSU printing mark: Before you insert a new PSU, be sure that it has
the same printing mark on its handle as that shown on the handle of a
remaining PSU. Double-check to avoid mixing a PSU of previous
Falcon II series. (See Figure 5-10)
