The IPC-623 is a 4U-high rackmount industrial computer chassis designed for multisystem applications. It can be a single or multi-segment industrial computer with up to 20 slots for quad-segment systems. It can be configured with a single power supply, or an N+1 redundant power supply with output of 810 W or greater. The IPC-623 comes with a unique alarm module. This module automatically detects the system operating conditions, such as power, HDD, fan, and system temperature. The front LED indicators show the system and power status clearly. In the event of system failure, the alarm module will make an audible beep to warn users to take essential actions.
