NOTE
If you will be working near multiple E4G-400 routers for an extended time, Extreme Networks recommends
that you wear hearing protection. When all the fans are operating, the noise level can be in excess of 7.2 B(A)
Declared Sound Power or 69 decibels Sound Power.
Replacing an AC Power Supply in the E4G-400 Router
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.
You need the following tools and materials to replace an AC power supply:
● Thermal protective gloves
● 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 the requirements listed under “Selecting Power Supply Cords” on page 99.
