Supplies
The BlackDiamond 12800 series switches can be powered by either AC or DC power supplies (PSUs).
Power supplies in the BlackDiamond 12800 series switches are fully fault tolerant and load-sharing in
an N+1 configuration. After the system is properly configured, if one PSU fails, the others will provide
sufficient power to operate a fully loaded switch.
