AC power cords including a safety ground and rated for 15A or higher.
Note: Do not hot swap the power supply if your switch has only one power supply. You must power
down the system to replace the power supply unit when there is only one PSU in the switch.
CAUTION
Risk of electric shock and energy
hazard. The two PSUs are inde-
pendent.
Disconnect all power supplies to
ensure a powered down state

2.2.4 Extracting and Inserting the Power Supply Unit
With both power supplies installed in the redundant configuration, either PSU may be extracted without
bringing down the system.
Note: Make sure that the PSU that you are NOT replacing is showing all green, for both the PSU and
status indicators.
Caution: The switch platform will automatically power on when AC power is applied.
There is no power switch. Check all boards, power supplies, and fan tray modules for
proper insertion before plugging in a power cable.
Caution: After inserting a power cable and confirming the green system status LED
light is on; make sure that the Fan Status indicator shows green.
If the fan status indicator is not green then unplug the power connection and check that
the fan module is inserted properly and that the mating connector of the fan unit is free
of any dirt and/or obstacles.
Caution: When turning off the switch, make sure ALL LEDS are off to ensure a pow-
ered down status.
