Install a 1600 W Internal AC Power Supply

To install a 1600 W AC power supply (either part no. XN-ACPWR-1600W-F or part no. XN-ACPWR-1600W-R) in a switch, follow these instructions.

All installed power supplies must have the same airflow direction (front-to-back or back-to-front) and must match the airflow direction of the installed fan modules.

1. Remove a blank panel from the back of the switch if necessary.
2. Verify that the new power supply is right side up.
3. Verify that the new power supply's airflow direction (front-to-back or back-to-front) is compatible with the other installed power supply (if any) and with the installed fan modules.
4. Carefully slide the power supply all the way into the power supply bay:

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

   Do not slam the power supply into the switch.

   

   Note

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

6. Connect the AC power cord.
   1. Slide the plastic cord retainer farther away from the back of the switch if necessary.
   2. Connect the AC power cord to the input connector.
   3. Open the clip and slip it over the barrel of the connector.

   Warning

   Always make sure that the source outlet is properly grounded before plugging the AC power cord into the AC power supply.

To install a second power supply, repeat this procedure.
