There are two power supply inlets in the system (for redundancy). The system can operate with only
one power supply connected. In case the power supply is an FRU, a second power supply unit can be
added to support hot-swap ability. Each power supply unit has a single 2 color LED on the right side
of the unit, that indicates the status of the unit.

Risk of Electric Shock! With the fan module removed, power pins are accessible within the
module cavity. Do not insert tools or body parts into the fan module cavity.
The following information does not apply to the SN2100/SN2010 systems. In these systems,
the power supply units are non-replaceable, and there is a designated LED for each unit in
the system’s front panel. (Front panel figures are located in the Introduction.)
