Meridian Data 16i ユーザーズマニュアル

Chapter 1 Introduction

1-5

• 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

turn the system on and off. (See Section 0)

• Cooling modules: The redundant cooling modules

ventilate the subsystem to maintain a cooling airflow

across the subsystem. (See Section 0)

1.1.2.6 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.
