• 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)
• PSU modules: The hot-swappable PSUs receive single-
phase power and deliver +5V, +12V, and +3.3V power to
the subsystem. A power switch is located on each PSU to
• Cooling modules: The redundant cooling modules
ventilate the subsystem to maintain a cooling airflow
across the subsystem. (See Section 0)
1.1.2.6 Backplane
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 user-serviceable components.
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. Hot-swap mechanisms are incorporated
to eliminate power surges and signal glitches that might occur while removing or
installing these modules.
