Replacing a Summit 750 W AC Power Supply
The Summit 750 W AC power supply is compatible with the Summit X460 series PoE-capable 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 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 a Summit AC power supply. You must obtain a power
supply cord that meets the requirements listed under
“Power Cord Requirements for AC-Powered
Switches and AC Power Supplies” on page 500
.
To replace a Summit 750 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 (see Figure 288.
3 Push the latching tab toward the power supply handle and pull outward on the handle to disengage
the power supply internal connectors (Figure 288).

4 Carefully slide the power supply the rest of the way out of the switch.
CAUTION
Power supplies may become very hot during operation. Wear thermal protective gloves when you
remove a power supply from an operating switch.
NOTE
If you are not installing a replacement power supply, install a cover over the unoccupied power supply
bay. Unoccupied bays must always be covered to maintain proper system ventilation and EMI levels.
5 Verify that the replacement power supply is oriented the same way as the unit you removed.
