2.8 BBU Installation
2.8.1 BBU Module Installation Overview
The BBU module is an optional item that can sustain cached data in the event of a
power outage or in the unlikely event that both PSUs have failed. Purchasing and
installing a BBU is highly recommended. The optional BBU provides additional data
security and helps minimize the chance of data loss during power shutdowns.
The BBU module is inserted into the subsystem in the module slot at the upper left
corner of the controller module. The BBU module is secured to the subsystem with
two (2) retention screws. When shipped, the BBU module slot in the subsystem rear
panel is covered with a metal dummy plate that must first be removed.
2.8.2 Installation Procedure
To install a BBU into the subsystem, please follow these steps:
Step 1. Using a screwdriver, loosen the two (2) retention screws located on
both sides of the dummy plate. (See Figure 2-2 )

Step 2. Once the retention screws are loosened, wedge a screwdriver
between the back of the dummy plate and the interior wall of the
subsystem enclosure. Gently lever the dummy plate out of the
enclosure. (See Figure 2-3 )
