DC power supply specifications
The VSP 8404–DC comes with one 800 W DC power supply and you can install a secondary power
supply for redundancy.
Important:
You must have either a power supply or a power supply cover in each bay to ensure proper
ventilation. Leaving a power supply bay unpopulated or uncovered impairs the ability of the fans
to cool the chassis.
Figure 3: DC power supply
The 800 W DC power supply uses a DC power supply wiring assembly to connect the power supply
to the DC power source.
