Replacing a 750 W AC Power Supply
The 750 W AC power supply is compatible with the Summit X460 series PoE-capable switches.
You need the following tools and materials to replace a 750 W AC power supply:
• Thermal protective gloves
• AC power cord, if you will not be re-using the cord from the removed power supply
An AC power cord is not included with an AC power supply. You must obtain a power supply cord
that meets the requirements listed in Power Cord Requirements for AC-Powered Switches and AC
Power Supplies on page 653.
These switches have two bays for hot-swappable power supplies. In a switch with a redundant power
configuration, you can replace one AC power supply without powering down the switch.
