+
+## Kernel modules and drivers
+
+The driver for interacting with Ingrasys S9280-64X is contained in the I2C 
+kernel module and initialization script. The initialization script loads 
+the modules in the correct order. It has been built and tested against
+the Linux 3.16 kernel. 
+
+The initialization script will modprobe the needed modules, navigate to the 
+module's device directory in sysfs, and write configuration data to 
+the kernel module.
+
+### IGB
+
+This is OOB Ports on front panel for management plane.
+
+The IGB module must be loaded first on Ingrasys S9280-64X platform.
+
+### I2C i801
+
+The I2C i801 on Ingrasys S9280-64X can be found in
+`/sys/bus/i2c/devices/i2c-0/`
+
+This is I2C bus for Clock Gen, DIMM channel and digital potentiometers. 
+
+The i801 module must be loaded second on Ingrasys S9280-64X.
+
+### I2C PCA9548
+The PCA9548 module on S9280-64X can be found in
+`/sys/bus/i2c/devices/i2c-0/` , `/sys/bus/i2c/devices/i2c-17/`, 
+`/sys/bus/i2c/devices/i2c-18/` , `/sys/bus/i2c/devices/i2c-19/`, 
+`/sys/bus/i2c/devices/i2c-20/`, `/sys/bus/i2c/devices/i2c-21/`,
+`/sys/bus/i2c/devices/i2c-22/`, `/sys/bus/i2c/devices/i2c-23/`,
+`/sys/bus/i2c/devices/i2c-24/`.
+
+The pca9548 module for zQSFP module get/set functions, PSU information, 
+fan status and EEPROM.
+
+## Hardware components
+
+The hardware components are initialized in the init script on S9280-64X. 
+The following describes manual initialization as well as interaction.
+The examples below are just for Ingrasys S9280-64X platform.
+
+### Hardware initialization
+
+When the sonic-platform-ingrasys-s9280 package is installed on the S9280-64X,
+it is automatically initialized. If you want to manual initialization, the 
+utility command usage as follows:
+```
+    i2c_utils.sh i2c_init
+```
+
+### EEPROM
+
+The EEPROM is including the board SKU, model name, vendor name, serial number, 
+and other information can be accessed with the specific eeprom kernel module.
+After using `modprobe eeprom_mb` to detect the eeprom, it will show up in sysfs.
+
+The hexdump utility can be used to decode the raw output of the EEPROM. 
+For example,
+```
+    bash# echo "mb_eeprom 0x55" > /sys/bus/i2c/devices/i2c-0/new_device
+    bash# cat /sys/bus/i2c/drivers/mb_eeprom/0-0055/eeprom | hexdump -C
+```
+
+### Front panel LEDs
+
+LEDs can be setup on/off by using i2c utility `/usr/sbin/i2c_utils.sh`.
+Utility function command usage as follows:
+
+```
+Status LED:
+    i2c_utils.sh i2c_sys_led green|amber on|off
+
+Fan status LED:
+    i2c_utils.sh i2c_fan_led green|amber on|off
+
+PSU1 status LED:
+    i2c_utils.sh i2c_psu1_led green|amber on|off
+
+PSU2 status LED:
+    i2c_utils.sh i2c_psu2_led green|amber on|off
+
+```
+QSFP Module Port LEDs control by ASIC library.
+
+
+### Fan speed
+
+Fan speed are controlled by the w83795 kernel module. 
+It can be found in `/sys/class/hwmon/hwmon2/device/`.
+If they were compiled as modules, you will need to modprobe w83795 for
+their sysfs entries to show up. Each fan has an `fan<N>_input` file 
+for reading the fan speed. And `pwm1` setting fan1 to fan4, 
+`pwm2` setting fan5 to fan8.
+
+There is docker-platform-monitor container installed fancontrol package that can
+automatic control platform fan speed.
+
+
+### Temperature sensors
+
+Temperature sensors are controlled by the w83795 kernel
+module. It can be found in `/sys/class/hwmon/hwmon3/device/`. 
+If they were compiled as modules, then you will need to modprobe w83795 for
+their sysfs entries to show up.
+`temp1_input` is front MAC temperature sensor. `temp2_input` is rear MAC 
+temperature sensor. 
+
+There is docker-platform-monitor container installed lm-sensors package that can
+monitor platform temperature. And `sensors` command can show each 
+temperature sensors status.
+
+### Power supplies
+
+Power supplies status and its EEPROM info can be used i2c utility 
+`/usr/sbin/i2c_utils.sh` to get.
+The usage as follows:
+```
+PSU EEPROM:
+    i2c_utils.sh i2c_psu_eeprom_get
+
+PSU Status:
+    i2c_utils.sh i2c_psu_status
+```
+
+### QSFPs
+QSFP modules are managed by the pca9548 kernel driver.
+The i2c utility `/usr/sbin/i2c_utils.sh` can be used to get status and
+module EEPROM informations.
+The usage as follows:
+```
+QSFP EEPROM:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-64]
+
+QSFP Insert Event:
+    i2c_utils.sh i2c_qsfp_status_get [1-64]
+    0 => not insert
+    1 => inserted
+```
