Troubleshooting
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 Cable LED flashes, it is
transferring data at a reduced bandwidth because you installed the PCIe x16 HIC
in a Gen 1 slot or a PCIe x8 (electrical) slot. If your HIC is PCIe x8, you installed
it in a Gen 1 slot. The HIC operates at full bandwidth when installed in a PCIe
Gen 2 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 x16 Gen 3
GPU or card.
Resolution:
Slot LEDs should light steady green. If they are flashing, it may be because the
GPUs in the slots do not have a processing load. Apply a processing load on the
GPUs. If the slot LEDs still flash green, check the vendor’s link for a driver
update.
Issue:
All Cable and Slot LEDs are lit green but your OS does not detect the GPUs.
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:
The front-panel LCD screen backlight is flashing on/off, which indicates a fault.
Resolution:
Press the MIB button momentarily to identify the MIB with the fault. Acknowledge
the fault by pressing the Menu button, which will stop the LCD flashing and the
LCD will remain at the fault.
Issue:
After acknowledging a fault, the front-panel LCD screen backlight continues
flashing on/off, which indicates two or more faults. If multiple faults have
occurred, when you acknowledge the first fault, the LCD will jump to the next
fault and the LCD backlight will once again flash on/off. This continues until you
clear all faults.
Resolution:
Press the MIB button momentarily to identify the MIB with the fault. Acknowledge
the fault by pressing the Menu button, which will either stop the LCD flashing and
the LCD will remain at the fault, or the LCD will jump to the next fault and the
LCD backlight will once again flash on/off.
Issue:
The front-panel LCD screen either does not respond or is blank even though
Xpander is operating.
Resolution:
Press and hold the MIB Select button to reset the Micro-Controller Unit (MCU).
