Troubleshooting Procedure
Issue:
The front-panel LCD asterisk does not flash.
Resolution:
Reset the LCD’s MCU by pressing and holding the left button for 3 seconds while
Xpander is running.
Issue:
The HB LED inside Xpander flashes green.
Resolution:
This is normal; it indicates that the on-board MCU is running properly.
Issue:
Cable LED inside Xpander does not light green.
Resolution:
Check the following:
•
Confirm that the HIC is firmly seated in a PCIe slot within the host computer.
•
Confirm that the cable connector is firmly seated HIC connector port.
Issue:
Cable LED inside Xpander flashes green even though I have a PCIe x16 HIC
and cable.
Resolution:
The internal Cable LED should light steady green if the HIC is in a PCIe Gen 3.0
slot. If the Cable LED flashes, it is transferring data at a reduced bandwidth
because you installed the PCIe x16 HIC in a Gen 1 or Gen 2 slot or a PCIe x8
(electrical) slot. The HIC operates at full bandwidth when installed in a PCIe Gen
3 slot.
Issue:
Slot LED inside Xpander does not light green.
Resolution:
Shut down the OS gracefully, power down Xpander and reseat the GPUs in each
PCIe slot. Make sure that you seat each GPU firmly in its slot and that you
connect all aux power connectors firmly.
Issue:
Slot LED inside Xpander flashes green even though I installed a PCIe Gen 3 x16
GPU or card.
Warning
Disconnect power to Xpander before connecting or disconnecting the HIC.
