To initialize the system, run "accton_as5812_54t_util.py install".
To clean up the drivers & devices, run "accton_as5812_54t_util.py clean".
To dump information of sensors, run "accton_as5812_54t_util.py show".
To dump SFP EEPROM, run "accton_as5812_54t_util.py sff".
To set fan speed, run "accton_as5812_54t_util.py set fan".
To enable/disable SFP emission, run "accton_as5812_54t_util.py set sfp".
To set system LEDs' color, run "accton_as5812_54t_util.py set led"
For more information, run "accton_as5812_54t_util.py --help".
====================================================================
Besides applying accton_as5812_54t_util.py to access peripherals, you can
access peripherals by sysfs nodes directly after the installation is run.
LED controls can be found under /sys/class/leds. The sysfs interface
color mappings are as follows:
Brightness:
0 => off
1 => green
2 => amber
3 => red
4 => blue
There are 5 system LEDs, loc, diag, fan, ps1, and ps2.
They are lit automatically by CPLD, but the loc and diag.
The loc led has only 1 color, blue.
The diag one has 3 colors: red, amber, and green.
Fan controls can be found in /sys/bus/i2c/devices/2-0066.
There are 12 fans inside 6 fan modules.
All fans share 1 duty setting, ranged from 0~100.
Three temperature sensors are controlled by the lm75 kernel modules.
They should already be visible under /sys/bus/i2c/drivers/lm75/.
Two power supplies are controlled by the CPLD.
Here provide their status under
/sys/bus/i2c/devices/10-0050 and /sys/bus/i2c/devices/11-0053.
There are 32 QSFP+ modules are equipped.
Apply "accton_as5812_54t_util.py show" to get their status.
Apply "accton_as5812_54t_util.py set sfp" to turn on/off light transmission.
Apply "accton_as5812_54t_util.py sff" to dump EEPROM information.
Before operating on that QSFP+, please make sure it is well plugged.
Otherwise, operation is going to fail.
