The SBC622 convection cooled front panel provides the following indicators:
The four general status LEDs provide status information as follows (left to right
on the panel):
• Boot status (RED): illuminates during BIOS boot and power‐on self test
operation only
• Power (GREEN): illuminates when all internal rail voltages are within oper‐
ating tolerances
• Hard Drive Activity (YELLOW): illuminates while S‐ATA drive accesses are
in progress
• BIT Fail (RED): illuminates when onboard BIT (optional) has detected an
error condition.
When the Processor/PCH are in the Power Management state, S5, all four front
panel LEDs illuminate.
The two LEDs integrated in the RJ45 receptacle for GbE ports provide link activity
and link speed status information for the Ethernet ports on SBC622 as follows (left
to right on the panel):
• Link Activity [GREEN]: illuminates during link, flashing during active data
transfers on the port
• Link Speed [YELLOW/GREEN]: link speed is 1 Gb/s when Green, 100 Mb/s
when yellow, 10 Mb/s when extinguished
The Reset switch is a standard push‐button. When activated, this switch forces a
hardware reset to the SBC622 assembly.
Signal assignments for the front panel connectors are provided in Appendix A:
