Power Supply Cords

If you use a 110 V AC power supply cord, the maximum DC output power of the power supply is
600 W. If you use a 220 V AC power supply cord, the maximum DC output power of the power supply
is 900 W.
An AC power supply cord is not shipped with the 600/900 W AC power supply. To purchase an AC
power cord, contact your local Extreme Networks Channel Account Manager or Sales Manager, or
purchase a cord from your local supplier. All power supply cords must meet the requirements listed in
"Selecting Power Supply Cords" on page
CAUTION
The 600/900 W AC power supply does not have a switch for turning the unit on and off. Remove the plug
from the electrical outlet to disconnect power to the 600/900 W AC power supply. Make sure that this connection is
easily accessible.
Make sure that the 600/900 W AC power supply circuit is not overloaded. Use proper over-current protection, such
as a circuit-breaker, to prevent over-current conditions.

Fuse

The Extreme Networks 600/900 W AC power supply line and neutral legs are both fused. Power to the
system may still be live if the neutral fuse is open. This is not a field operator replaceable fuse. In the
event of failure, immediately return the Extreme Networks 600/900 W AC power supply for a complete
replacement.
WARNING!
Field operators must not attempt to configure or replace fuses in Extreme Networks 600/900 W AC power
supplies. In the event of failure, immediately return the defective Extreme Networks 600/900 W AC power supply for
a complete replacement.
