ACP-4320 User Manual 2
Chapter 1 General Information
1.1 Introduction
The ACP-4320 is a 4U-high rackmount industrial computer chassis
designed for building mission-critical applications. With the latest indus-
trial design on its outlook, the ACP-4320 breakthroughs the traditional,
rigid impression of industrial PCs, and provides users with both a high-
performance and a state-of-the-art operating platform.
Dual front-accessible SATA HDD trays for easy maintenance
The ACP-4320 is supplied with two front-accessible SATA HDD trays,
which provide the most economic and user-friendly solution for data stor-
age. Users may easily replace a SATA HDD without opening the chassis
cover. Other data storage options include two 5.25" drive bays for optical
disk drives and one 3.5" drive bay for floppy drive disk or internal 3.5"
hard drive disk. Moreover, the front accessible USB interface can be
connected with various peripheral devices for data input, backup, and
transferal.
Unique alarm detection and notification to reduce system down time
The ACP-4320 has a unique alarm module. This module automatically
detects the system operating conditions, such as power, HDD, FAN, as
well as in-chassis temperature, and it may show the system status on the
front LED indicators. If any failure happens, the module will also give an
audible alarm to notify users to take necessary actions.
Versatile industrial features
The ACP-4320 supports both an ATX/mATX motherboard and an up to
15-slot backplane, to bring users the flexibility on system configuration
planning.
It also provides a wide range of ATX power supply options for user selec-
tion: from 300W to 400W for both single and redundant power supply.
The lockable front door prevents from any unauthorized access to data
storage zone. Moreover, the streamlined in-chassis airflow design keeps
the system cool, while the easy-to-maintain fans and filters shorten the
system's MTTR (Mean Time to Repair). All these outstanding features
make the ACP-4320 the best choice for price, performance and overall
cost of ownership.
