Installation Guide

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 1100 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 1100 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.
See Figure 404.

4. Carefully slide the power supply the rest of the way out of the switch.
Caution
Power supplies can 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, and has
the same airflow direction.
