Power Supply Cords
The Extreme Networks 700/1200 W AC PSU(s) can be used with either a 110 V AC or a 220 V AC
power supply cord. If you use a 110 V AC power supply cord, the maximum DC output power of
the PSU is 700 W. If you use a 220V AC power supply cord the maximum DC output power of the PSU
is 1200 W.
An AC power supply cord is not shipped with the 700/1200 W AC PSU. 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 172 .
Fuse
The Extreme Networks 700/1200 W AC PSU line and neutral legs are both fused. Power to the switch
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 700/1200 W AC PSU for a complete replacement.
WARNING!
Field operators must not attempt to configure or replace fuses in Extreme Networks 700/1200 W AC PSUs! In the
event of failure, immediately return the defective Extreme Networks 700/1200 W AC PSU for a complete
replacement.
