The chapter describes the power supply units used with the BlackDiamond 8800 series switches.

The BlackDiamond 8800 series switches can be powered by either AC or DC power supplies (PSUs). 
AC power supplies in the BlackDiamond 8800 series switches are fully fault tolerant and load-sharing in 
an N+1 configuration. For a switch using DC power supplies in an N+N configuration, each group of 
power supplies can provide A/B feed redundancy for the system. After the system is properly 
configured, if one PSU fails, the others will provide sufficient power to operate a fully loaded switch.

The BlackDiamond power supply units are intended for use in specific BlackDiamond switches only.
