An E4G-400 router accommodates one or two 300 W power supplies. You can combine AC and DC power supplies in the same E4G-400 router. In a redundant power configuration, both power supplies are fully fault-tolerant and load-sharing. You can remove one power supply without interrupting router operation.
Note
An AC power input cord is not provided with a 300 W AC power supply. You can order an appropriate cord from Extreme Networks or from your local supplier. The power cord must meet the requirements listed in Power Supplies for the E4G-400 Router.
