Chassis Power Supply Architecture

 The following diagram shows the general power supply architecture for a

single Prisma II XD Platform chassis.

 Each AC-to-DC bulk power supply module feeds a separate, dedicated

DC-to-DC converter assembly. The chassis ships with two DC-to-DC

converters installed, but without either AC-to-DC bulk power supply

module installed.

 Each DC-to-DC converter can power a full chassis on its own. The use of

dual independent converters, together with dual AC-to-DC bulk power

supplies, allows for full power supply redundancy.
