a reset button and LEDs for power status, HDD operation and Ethernet communication. The built-in high speed IDE controller provides two separate IDE channels with Ultra DMA/33 mode. The user-defined J3 connector is designed to support up to four IDE devices and two floppy drives. These drives can simply be connected to the backplane or to the rear transition board for easy service and maintenance.
Meets Industrial and Computer-Telephony Applications Requirements
The MIC-3368 is designed for use in mission critical applications. It accepts a CompactFlash™ memory card on either the rear transition board or MIC-3368 itself, thus eliminating the need to use a fragile rotating hard drive. A watchdog timer can automatically reset the system if the system stops due to a program bug or EMI. The two-layer front panel design complies with IEEE 1101.10. Connectors are firmly screwed to the front panel, and the replaceable shielding gasket is attached to the panel edge. This reduces emissions and gives better protection against external interference.
