Replacing a Summit 350 W or 715 W AC Power Supply

Before you begin

The Summit 350 W AC power supplies are compatible with X460-G2 PoE switch models that have the same airflow direction as the power supply. Part number 10953 is compatible with the X465-24S, X465-24XE, and X465-48T model switches.

The Summit 715 W AC power supplies are compatible with the X450-G2, X460-G2, and X465 PoE 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 715 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 350 W or 715 W AC power supply, follow these steps:

  2. Note the orientation of the installed power supply, and the location of the latching tab at the right of the unit.

  6. Carefully slide the power supply all the way into the power supply bay, as shown in Installing A Summit 350 W or 715 W AC Power Supply.
  7. Push the power supply in until the latch snaps into place.
