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.

Issue:

The passively-cooled GPUs or accelerators in Xpander are overheating.

Resolution:

Make sure you have installed blank end brackets (L-brackets) for each empty
Xpander slot. The blank end brackets are essential to assure proper cooling,
especially passively-cooled accelerators (such as Intel Xeon Phi coprocessor or
GPUs like NVIDIA Tesla K40 / K80 or Grid K2, as well as AMD Firepro S9100 /
9150 / 9170).
