Replacing an AC Power Supply

The E4G-400 routers have two bays for hot-swappable power supplies.

In a router with a redundant power configuration, you can replace one AC power supply without powering down the router.

Before you start, have the following items on hand:

Thermal protective gloves.
An AC power cord, if you will not be re-using the cord from the removed power supply.
An AC power cord is not included with the AC power supply. You must obtain a power supply cord that meets requirements. See Selecting Power Supply Cords for more information.

When replacing a power supply unit, be sure to observe all of the safety recommendations in Installing Power Supply Units and Connecting Power.

To replace the AC power supply in an E4G-400 router, follow these steps:

Disconnect the AC power cord from the wall outlet and from the power supply.
Note the orientation of the installed power supply and the location of the latching tab at the right of the unit.
Push the latching tab toward the power supply handle and pull outward on the handle to disengage the power supply internal connectors.

Removing a 300 W AC Power Supply
Carefully slide the power supply the rest of the way out of the router.

Caution
Power supplies can become very hot during operation. Wear thermal protective gloves when you remove a power supply from an operating router.

Note
If you are not installing a replacement power supply, install a cover over the unoccupied power supply bay. Unoccupied bays must always be covered to maintain proper system ventilation and electromagnetic interference (EMI) levels.
Verify that the replacement power supply is oriented the same way as the unit you removed.
Carefully slide the power supply all the way into the power supply bay.
Push the power supply in until the latch snaps into place.

Installing a 300 W AC Power Supply

Caution
Do not slam the power supply into the router.
Connect the AC power cord to the input connector on the power supply and rotate the wire clip into place over the power cord connector.
Connect the other end of the power cord to an AC power outlet.

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