CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when installing or servicing the power supply module. Failure to
observe this caution could result in damage to, and subsequent failure of, the
power supply module.
Installation
The CPSMP-200 AC power supply module may replace an existing AC
module, or it may be installed as the redundant power supply module in
either an AC-powered or a DC-powered PointSystem™ chassis.
Switch Settings
The CPSMP-200 power supply module has 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
configuration of ‘Primary’, unless changed at the software interface to
‘Secondary’.
• When set to ‘Manual’, the power supply module has the configuration as
set by the Primary/Secondary switch. The software interface cannot
change the setting.

Primary/Secondary Switch
The Primary/Secondary switch allows the module to be configured as the
‘Primary’ or as the ‘Secondary’ power supply.
• As the ‘Primary’ power supply, it provides power to the entire chassis.
• As the ‘Secondary’ power supply, it waits in stand-by mode, 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 mode 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.
