Installing Internal Power Supplies
If your switch does not come with an installed internal power supply, you can install one or two power supplies as needed.
The VSP 7400 Series switches support 750 W internal power supply units. The switch supports two AC power supplies, two DC power supplies, or one AC and one DC power supply.
Follow the instructions in the following sections to install the appropriate power supply and connect power to the switch.
The power supply slot on the left is for power supply number two and the power supply slot on the right is for power supply number one.
