Power Supplies for BlackDiamond
8800 Series Switches
Extreme Networks 700/1200 W AC Power Supply
Extreme Networks 600/900 W AC Power Supply
Extreme Networks 1200 W DC Power Supply
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 power supply fails, the others will provide sufficient power to operate a fully loaded switch.
The BlackDiamond power supplies are intended for use in specific BlackDiamond switches only.
The
following table
lists the BlackDiamond 8800 Series switches and their compatible power supplies.
