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.
•
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.
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.
•
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.
Configuring Two Power Supply Modules
•
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.
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.
