Power Supply Module Maintenance

3.4.1

Primary/Secondary-Management/Manual Switch

Both the AC (CPSMP-200) and DC (CPSMP-210) power supply modules have a set
of Primary/Secondary-Management/Manual switches installed on the circuit board.
Management/Manual Switch
The Management/Manual switch allows the PointSystem™ software to control and
override the physical setting on the Primary/Secondary switch.
•
•
Primary/Secondary Switch
The Primary/Secondary switch allows the power supply module to be configured as
the 'Primary' or as the 'Secondary' power supply module.

Configuring Two Power Supply Modules
•
•
NOTE: At least one power supply module must be set to 'Primary.' If both modules
are set to 'Secondary,' neither will supply power to the chassis.
CAUTION: In a 0 - 60°C (32 - 140°F) environment, two power supplies must be
installed and both must be configured for load sharing.

When set to 'Management', the power supply module has the default setting of
'Primary' unless changed, at the software interface, to 'Secondary'.
When set to 'Manual', the power supply module is set by the
Primary/Secondary switch. The software interface cannot change the setting.
As the 'Primary' power supply, it provides power to the entire chassis.
As the 'Secondary' power supply, it waits in stand-by, ready to supply power to
the chassis in the event of power failure from the 'Primary' power supply.
For load sharing, where each module supplies power to half the chassis, set
both power supply modules to 'Primary'.
For back-up power supply, set one power supply module to 'Primary' (which
supplies power to the entire chassis) and the other to 'Secondary'. In this mode,
the secondary module is in stand-by and takes over in the event of a power
failure of the 'Primary' module.
