NOTE: (Optional) For systems that use the SmartFusion chip, the eepromtool also has two companion
configuration files — default_mailbox_eeprom.cfg which holds information for the --
psueepromdump
command, and default_fan_mailbox_eeprom.cfg which holds information for the
--faneepromdump command.
ethtool
The ethtool provides management interface details.
fantool
The fantool tests the fans in the system, sets and reports the fan speeds and the fan tray field replaceable
unit (FRU) registers.
The fantool also reports the airflow direction of the fans. The psutool command controls the PSU fans.
Tests
The fantool tests the fans by setting them to different speeds and then verifying the configured fan speeds.
Registers and values are passed as hexadecimal values with or without the preceding 0x. Fans display from 1
to Max System Fans.
