• Use the Supermicro xgicfg command from a DOS-bootable thumb-drive
image
• Use in-band ipmitool from the operating-system prompt
• Use the ipmitool command or the AOC-SIMSO web interface to communicate
with the BMC
Caution: The DEFAULTP.EXE command resets all BMC network settings to
their default setting.
• If the BMC does not respond, you can reset it to default values with the SuperMicro
DEFAULTP.EXE command from a DOS-bootable thumbdrive image
Use the following tools and techniques to troubleshoot the power components on the
SGI Virtu VN200:
• Check the power supply status LEDs. Each power supply has an green LED that
illuminates when DC power is present. When a supply fails, the PWR FAIL LED on
the control panel illuminates and the power-supply status LED does not illuminate.
• Use the IPMI web interface, the ipmitool command, or the power-supply LEDs to
determine which supply has failed
• Hot-swap the failing supply without powering the node down (if the node has a
redundant power supply) to perform fault isolation
If a fan or temperature fault occurs, the red ALERT LED on the control panel illuminates.
• Use ipmitool or the IPMI web interface to determine which fan has failed
• Remove the graphics node from the rackmount shelf and open the side access panel
to replace the failed fan
