ACP-4000 is a 4U height 14-slot rackmount IPC chassis designed for building mission-critical applications. The unit includes an optional versatile 14-slot passive-backplane (which supports ATX M/B form factor), high-efficiency 300W ATX with PFC (power factor correction) power supply, and easy to maintain dual cooling fans. A fault detection and alarm notification system monitors the system status, including power supply, HDD, temperature and cooling fans to minimize the system down time. A wide range of standard computing peripherals can be integrated with the chassis to meet different application development under mission-critical environment 24 hours a day, 7 days a week.
