====================================================================
|
||
|
|
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.
