3.2 DC Power Supply Module
The CPSMC1910-100 PointSystem™ chassis is equipped with a DC power supply
module (P/N CPSMP-210) installed in the back of the chassis. The power supply
module supplies power to the chassis, installed media converter slide-in-modules,
management modules, and the optional fan module.
The components of the DC power supply module include:
• A set of three (3) external power connectors that distribute power from an exter-
nal 48-VDC outlet to a chassis ground connector, a positive (+) connector, and
a negative (-) connector on the DC power supply module.
• An On/Off switch that, when set to “I”, allows the module to supply power to
the chassis, and any installed modules.
•A power LED indicator.
•A fan to prevent the power supply module from overheating.
•A fuse installed on the power supply module’s circuit board.
Optional Redundant DC Power Supply Module
An extra installation space is available in the back of the chassis for installing an
optional redundant DC power supply module (P/N CPSMP-210).
See section 3.4 Power Supply Module Maintenance for instructions on installation.
