====
There are 64 QSFP+ modules supported in qfx5210 platform. EEPORMs will be
mapped under /sys/bus/i2c/devices/[25-88]-0050/ sysfs directory
mapped under /sys/bus/i2c/devices/[25-88]-0050/ sysfs directory.
FEC should be turned on for SR4 optics and should be turned off for LR4
optics.
As an example, see this configuration for FEC for 100G SR4 optics in
/etc/sonic/config_db.json

=================
Linux poweroff commands such as 'poweroff', 'shutdown', 'halt', etc. will not
power off qfx5210 platform as there are custom CPLDs control the power off
sequences. Use the command 'sudo platform_poweroff' to power off qfx5210
platform
sequences. So acpi poweroff hooks are added for powering off the qfx5210. The
following messages are displayed in the console towards end of poweroff
sequence:
[ 52.500807] System halt/power_off
[ 52.866331] reboot: Power down
[ 52.903257] pm_power_off: qfx5210_cpld_power_off
Once the above messages are seen, you can safely remove the power to the system.
Similarly platform reboot sequences are in place for system reboot. The following
messages are displayed in the console when the system is rebooted:
[ 6053.163363] System restart: qfx5210_cpld_soft_reset
Platform monitoring daemon
