Replacing a Summit 850 W AC Power Supply
The Summit 850 W AC power supplies are compatible with the Summit X650 series 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 850 W AC power supply:
• Thermal protective gloves
• AC power cord, if you will not be re-using the cord from the removed power supply
To replace a Summit 850 W AC power supply, follow these steps:
1. Disconnect the AC power cord from the wall outlet and from the power supply.
2. Note the orientation of the installed power supply, and the location of the latching tab at the right of
the unit.
3. Push the latching tab toward the power supply handle and pull outward on the handle to disengage
the power supply internal connectors.
