the subsystem chassis.

2.3.6BBU

An Li-ION battery backup unit (BBU) module (see Figure 2.10) can sustain cache memory for days after a power failure. If you purchased a BBU, it will be installed on the upper left side of the controller module in the rear of subsystem chassis.

Fig. 2.10 BBU Module

In accordance with international transportation regulations, the BBU module is only charged to between 35% and 45% of its total capacity when shipped. Therefore, when powering on the subsystem for the first time (see Section 5.3 Power On) the BBU will begin to charge its batter-
