Board LEDs
There are two sets of 4 LEDs on the back of the HIB35-x4. They are located in the upper right hand corner of the board. The first set is labeled as
follows:
PWR--Power good
RST—Card edge Reset
CRST—Cable Reset
FE—PEX Fatal Error. One Red led on the card indicates a switch failure (labeled as FE)
Power LED should always be solid when the card is active.
o
RST and CRST will flash when reset occurs.
o
FE will be lit only when the PCIe switch has detected a fatal error.
The second set of 4 LEDs show the PCIe lane width connection through the card edge to host system. LEDs 0-3 represent lanes 1-4. These LEDs
will be solid when a link is established and off when there is NO link. If an LED is flashing, the link is training unsuccessfully.
