Power supply and fan units
The DS5100 and DS5300 have two power supply and fan units. Each power supply
and fan unit contains a power supply, a fan, and a battery charger. Each power
supply provides power to the controllers by converting incoming ac voltage to the
appropriate dc voltages. If one power supply and fan unit is turned off or
malfunctions, the remaining power supply and fan unit can maintain electrical power
and cooling to the storage subsystem.
Note: Contact IBM for information about possible future dc-to-dc power supply
support.
Install the power supply and fan units from the front of the storage subsystem.
Figure 7 on page 20 shows how a power supply and fan unit slides into the storage
subsystem. The levers that secure the left power supply and fan unit into the
