Module Power-down Sequence
The module requires a controlled power-down sequence. Uncontrolled
removal of power while the module is operating carries the risk of data
corruption. The consequences of this corruption range from longer TTFF
to complete system failure. The appropriate procedure to remove power is
shown in Figure 9 below.
