Installing an 850 W Internal AC Power Supply

The Summit X650 series switch is shipped without installed power supplies.

The switch accommodates one or two Summit 850 W power supply units.

Caution

Caution

Make sure that the AC power supply circuit is not overloaded. Use proper overcurrent protection, such as a circuit breaker, to prevent overcurrent conditions.

An AC power cord is not included with the Summit AC power supply. You can purchase AC power cords for use in the US and Canada from Extreme Networks or from your local supplier. The cord must meet the requirements listed in Power Cord Requirements for AC-Powered Switches and AC Power Supplies.

To install an 850 W AC power supply in a Summit X650 series switch, follow these steps:

  1. Attach an ESD-preventive wrist strap to your bare wrist and connect the metal end to an appropriate grounding point.
  2. If necessary, remove a blank panel from the back of the Summit X650 series switch.

    If power supplies are not installed in both power supply bays, be sure to install a cover over the unoccupied bay. Unoccupied bays must always be covered to maintain proper system ventilation and EMI levels.

  7. Connect an appropriate AC power cord to the power input socket; connect the other end of the power cord to a grounded AC power outlet.
