MIC-3368 Series User Manual -- Page

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.
