Contents of this package:
|
||
|
|
module - Contains source code of as7326 kernel driver modules.
|
||
|
|
util - operational scripts.
|
||
|
|
|
||
|
|
Sonic creates a docker container and run building process under it.
|
||
|
|
If user tries to built new drivers, please get into that docker and
|
||
|
|
dpkg-buildpackage for them.

The code for integacting with Accton AS7326-56X has 2 parts,
|
||
|
|
kernel drivers and operational script.
|
||
|
|
The kernel drivers of peripherals are under module/ directory.
|
||
|
|
1. These drivers can be built to individual ko during dpkg-buildpackage.
|
||
|
|
2. A operational script, accton_as7326_util.py, for device initializatian.
|
||
|
|
Run "accton_as7326_util.py install" to install drivers.
|
||
|
|
|
||
|
|
To initialize the system, run "accton_as7326_util.py install".
|
||
|
|
To clean up the drivers & devices, run "accton_as7326_util.py clean".
|
||
|
|
To dump information of sensors, run "accton_as7326_util.py show".
|
||
|
|
To dump SFP EEPROM, run "accton_as7326_util.py sff".
|
||
|
|
To set fan speed, run "accton_as7326_util.py set fan".
|
||
|
|
To enable/disable SFP emission, run "accton_as7326_util.py set sfp".
|
||
|
|
To set system LEDs' color, run "accton_as7326_util.py set led"
|
||
|
|
For more information, run "accton_as7326_util.py --help".
|
||
|
|
|
||
|
|
====================================================================
|
||
|
|
Besides applying accton_as7326_util.py to access peripherals, you can
|
||
|
|
access peripherals by sysfs nodes directly after the installation is run.
|
||
|
|
|
||
|
|
System LED:
|
||
|
|
There are 5 system LEDs at the lower-left corner of front panel.
|
||
|
|
They are loc, diag, fan, ps1, and ps2.
|
||
|
|
The sysfs interface color mappings are as follows:
|
||
|
|
Brightness:
|
||
|
|
0 => off
|
||
|
|
1 => green
|
||
|
|
2 => amber
|
||
|
|
3 => red
|
||
|
|
4 => blue
|
||
|
|
But not all colors are available for each LED.
|
||
|
|
|
||
|
|
Fan Control:
|
||
|
|
There are 10 fans inside 6 fan modules.
|
||
|
|
All fans share 1 duty setting, ranged from 0~100.
|
||
|
|
|
||
|
|
Thermal sensers:
|
||
|
|
3 temperature sensors are controlled by the lm75 kernel modules.
|
||
|
|
|
||
|
|
PSUs:
|
||
|
|
There 2 power supplies slot at the left/right side of the back.
|
||
|
|
Once if a PSU is not plugged, the status of it is shown failed.
|
||
|
|
|
||
|
|
There are 48 SFP+ and 8 QSFP modules are equipped.
|
||
|
|
Before operating on PSU and QSFP+, please make sure it is well plugged.
|
||
|
|
Otherwise, operation is going to fail.
