the switch for 1+1 redundancy.
To ensure heat dissipation, make sure all fan tray slots on the switch have fan trays installed and the
fan trays are the same model.

WARNING!
When the switch has power supplies in redundancy, you can replace a power supply without
powering off the switch. Make sure the power supply to be replaced is powered off before you
replace it.
