1.2.7
Serial ports
One RJ45 COM1 port (RS-232/422/485) is provided on the front panel with one
RJ45-to-DB9 adapter cable provided as an accessory. Two COM ports are routed to
the rear I/O module via the J5 connector. If you encounter problems with a serial
device, check the pin assignments listed in Appendix A. The IRQ and address range
for these ports are fixed. If a disabled port or parameter modification is required, refer
to Chapter 2.
1.2.8
USB Port
MIC-3399 provides three USB 3.0 type-A ports on the front panel and up to six USB
2.0 and three USB 3.0 interfaces via a J3/J5-to-CompactPCI connector. The MIC-
3399 USB interfaces comply with USB, R2.0 and 3.0, specifications and are fuse pro-
tected (5 V @ 1.1 A).
1.2.9
System Reset and BMC Reset Button
MIC-3399 provides a system reset button located on the front panel. The system
reset button resets all payload and application-related circuitry. However, it does not
reset the system management (IPMI)-related circuitry. A separate BMC reset button
on the front panel is provided for BMC and related hardware control.
1.2.10
XMC IEEE1386.1 Compliant
Additional I/O or co-processing functionality is supported with the inclusion of add-on
XMC modules. MIC-3399 supports one single-width XMC that is fully compliant with
VITA 42.0-2005 and 42.3-2006. XMC supports PCIe x8 Gen3 at 3.3V, 5V, and 12V
depending on usage.
The two-layer front panel design complies with IEEE 1101.10 standard specifications.
Connectors are firmly screwed into the front panel, and a shielding gasket is attached
to the panel edge. This reduces emissions and increases protection from external
interference.
1.2.11
Watchdog Timer
An onboard watchdog timer provides system reset capabilities via software control.
The programmable time interval ranges from 1 to 255 seconds.
1.2.12
BIOS
MIC-3399 features dual 16 MB SPI flash containing specific AMI BIOS firmware with
a fail-over mechanism, satisfying industrial and embedded system requirements.
