Xpander-desktop-elite-g3 20190201
Resolution:
Slot LEDs should light steady green if a PCIe Gen 3 x16 GPU or other card is
installed. 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:
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:
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:
Press and hold the Menu (left) 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.
