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.
The AT-x510-28GPX and AT-x510-52GPX Switches have a PoE budget
of 370 watts when both power supplies are active and 185 watts when only
one power supply is active. For further information, refer to “Power
Budget” on page 27.
Refer to “Technical Specifications” on page 85 for the input voltage range.

Power cord is used as a disconnection device. To de-energize
