Chassis Power Supply Architecture

 The chassis can operate from utility AC power or from external -48 VDC

power.

 For AC operation, one or two AC-to-DC bulk power supply modules are

installed in the chassis. Each of these modules supplies -48 VDC power to

one of two DC-to-DC converter assemblies inside the chassis

 For DC operation, one or both AC-to-DC bulk power supply modules are

removed, and power for one or both internal DC-to-DC converter

assemblies is supplied from external -48 VDC power source.

 The DC power connector can serve one of two functions, depending on

the power supply configuration:

When the associated AC-to-DC bulk power supply slot is empty, its

DC power connector acts as an inlet for external -48 VDC.

When the associated AC-to-DC bulk power supply slot is populated,

its DC power connector acts as an outlet for -48 VDC from the bulk

power supply module.
