Replacing a Summit 300 W AC Power Supply
The Summit 300 W AC power supplies are compatible with the Summit X460 series non-PoE switches.
These switches have two bays for hot-swappable power supplies. In a switch with a redundant power
configuration, you can replace one Summit AC power supply without powering down the switch.
You need the following tools and materials to replace a Summit 300 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 a Summit AC power supply. You must obtain a power
supply cord that meets the requirements listed under “Selecting Power Supply Cords” on page 339.
To replace a Summit 300 W AC power supply:
1 Disconnect the AC power cord from the wall outlet and from the power supply.
2 Note the orientation of the installed power supply.
