Power

Supply

inputs

Has

two

separate

connectors

(FS1and

FS2)

for

redundant

dc

power

supplies.

The

positive

supplies

feed

a common

bus

via

auctioneering

diodes.

When

auctioneering

takes

place

outside

the

card,

the

required

power

may

be

supplied

via

a single

connector.
