Installing a 350 W, 715 W, 770 W, 1100 W, or 2000 W Internal AC Power Supply

Warning

To prevent an electrical hazard, make sure that the AC power cord is not connected to the power supply before you install the power supply in the power supply bay.

Caution

Make sure 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 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 a 350 W, 715 W, 770 W, 1100 W, or 2000 W AC power supply in a switch, follow these steps:

1. If necessary, remove a blank panel from the back of the switch.
2. Verify that the power supply is right side up.
3. Verify that the power supply's airflow direction (front-to-back or back-to-front) is compatible with the switch.
4. Carefully slide the power supply all the way into the power supply bay, as shown in Installing a Summit AC Power Supply (770 W Model Shown).

5. Push the power supply in until the latch snaps into place.
   

   Caution

   Do not slam the power supply into the switch.

   

   Note

   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.
6. Connect the power cord to the power supply.
   If the power supply is equipped with a power cord retainer, use the retainer to secure the power cord to the power supply.
7. Connect the power cord to a grounded AC power outlet.
   

   Warning

   Always make sure that the source outlet is properly grounded before plugging the AC power cord into the AC power supply.
8. To install a second power supply, repeat the procedure.
