Installing an AC Power Supply

You can install an AC power supply in an E4G-400 router.

Warning

To prevent an electrical hazard, make sure that the AC power cord is disconnected from the power supply before you install the power supply in the router.

Caution

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

1. On the rear panel of the E4G-400 router, remove the blank panel from the power supply tray as shown in the following figure.

   Note

   If power supplies are not installed in both power supply bays, be sure to install a panel to cover the unoccupied bay. The panel is required for maintaining proper system ventilation and EMI levels.
4. Connect the power cord to the power input connector and rotate the wire cord retainer over the power cord connector to hold the connector in place.
