Power Supplies

The x510 Series switches have two AC power supplies with separate AC
connectors on the back panels. The power supplies, which are not field-
replaceable, provide a switch with power redundancy and protect against
interruptions to network operations in the event one of the power supplies
loses power or fails. Power redundancy is available only when both AC
connectors on a switch are connected to power sources.
Refer to "Technical Specifications" on page 103 for the input voltage
range.
