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).
Issue:
The front-panel LCD screen either does not respond or is blank for a particular
MIB even though Xpander and the MIB are both operating.
Resolution:
Select the appropriate MIB using the MIB Select (left) button. Press and hold the
Menu (middle) button for 3 seconds to reset the Micro-Controller Unit (MCU). If
the Xpander is running, the Xpander fans will turn on full speed for 10 seconds
and then slow down to the operating speed set by the MIB local temperatures.
