Chapter 1 Introduction
•BBU module: An optional BBU module sustains unfinished writes cached in memory during a power
outage in order to prevent data loss. (See Section 0)

•Cooling modules: The redundant cooling modules ventilate the subsystem to maintain a cooling airflow across the subsystem. (See Section 0)
1.1.2.6Backplane Board
An internal backplane board separates the front and rear sections of the SecurStor 16I. The PCB board consists of traces for logic level signals and low voltage power paths. It contains no
WARNING!
When inserting a removable module, DO NOT USE EXCESSIVE FORCE! Forcing or slamming a module can damage the pins on the module connectors either on the module itself or on the backplane. Gently push the module until it reaches the end of module slot. Feel the contact resistance and use slightly more pressure to ensure the module connectors are correctly mated. If the module comes with ejection levers or retention screws, use them to secure the module.
1.2 Subsystem Components
The SecurStor 16I houses many active components and most of them can be accessed through either the front or rear panel. The modular design of the active components facilitates their easy installation and removal.
