Overview of the BlackDiamond X8 Series
Power Supplies
The BlackDiamond X8 series switch is powered by AC power supplies that are installed at the top front
of the chassis. The power supply bay in the BlackDiamond X8 switch can accommodate up to eight AC
power supplies.
The BlackDiamond X8 AC power supplies can operate from 110 V AC or 220 V AC and automatically
adjust to the supply voltage. With 220 V AC input, the BlackDiamond X8 AC power supplies can
operate in an N+N or N+1 configuration.
Power supplies in the BlackDiamond X8 switch are fully fault tolerant and load-sharing in an N+1
configuration. After the system is properly configured, if one power supply fails, the others provide
sufficient power to operate a fully loaded switch.
