Overview of BlackDiamond 8800 Series
Power Supplies
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.
Table 13 lists the BlackDiamond 8800 series switches and their compatible power supplies.
