Chapter 1: Introduction

Subsystem Components

1-11

• COM Port

All controller modules come with one RS-232C (audio jack) serial port. The serial port is

used for local access to the system-embedded configuration utility over the included

serial port cable.

DIMM Module

The controller module comes with a preinstalled 256MB capacity or above DDR RAM

DIMM module and can support a larger capacity up to 2GB. The DIMM module is

mounted in an easily accessible location on the controller board. However, when the

DIMM module is being changed, the controller module must be removed from the

subsystem chassis.

1.2.4 Optional BBU Module

Part Number: - GALHDX-9273CBT-C

An optional, separately purchased Li-ION battery backup unit (BBU) module can sustain

cache memory for days after a power failure. If you purchased a BBU, it will be installed

on the upper left corner of the controller module in the rear of subsystem chassis. Please

refer to Chapter 2 for installation details.

Figure 1-16: 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 4.4) the BBU will begin to

charge its batteries to their full capacity. It normally requires approximately seven (7)

hours for the battery to be fully charged. If the battery is not fully charged after seven (7)

hours (its LED is still flashing), there is a problem with the BBU module and you should

contact your subsystem vendor immediately. While the battery is being charged, the LED

on the BBU rear panel and the fifth LED on the controller module will flash. (See

Chapter 3 for details on the LED indicators.)
