Conguration le format

The eeprom devices display under the corresponding i2c bus number. Whenever you add a new EEPROM to the bus number, the

number of devices in each bus number updates. Each eeprom eld is separated by the ‘|’ character. The order of the elds is:

1 Name of the EEPROM. Provides the same name at the eeprom option in the eepromtool.

2 The bus to which the EEPROM connects.

3 The i2c path of the EEPROM. If a MUX is present, the MUX address, oset, and value are separated by colons.

4 The i2c address of the EEPROM.

5 Species if the device is a 16–bit address access.

6 Byte count to read or write.

7 Species the format of the data in the eeprom as tlv or flat.

8 Write protect register, if applicable.

9 Write protect register mask.

10 Bus Return to Normal — Any bus congurations needed to return the bus to a valid setting. If you need any MUX settings, they are

listed as address : register : mask : value. Each successive MUX setting is separated with a :,:.

NOTE

: (Optional) For systems that use the SmartFusion chip, the eepromtool also has two companion conguration les —

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 eld replaceable unit (FRU) registers.

The fantool also reports the airow direction of the fans. The psutool command controls the PSU fans.
