Installing Summit 450 W and 550 W Power Supplies
Summit 450 W power supplies are compatible with the Summit X480 series switches and with Summit
X670 series switches that have front-to-back ventilation airflow. The Summit 550 W power supplies are
compatible only with Summit X670 series switches. They are available in versions for switches with
either front-to-back or back-to-front airflow.
The Summit X480 and X670 series switches are shipped without installed power supplies; they
accommodate one or two Summit 450 W or 550 W power supply units.
NOTE
You cannot combine 450 W power supplies and 550 W power supplies in the same Summit
X670 series switch.
Airflow Direction Requirements
The Summit X670 switches are available in models with the following ventilation airflow direction:
●
The air flows from front to back. In these switch models, the fan modules are labeled
Air Out
.
●
The air flows from back to front. In these switch models, the fan modules are labeled
Air In
.
The airflow direction of the power supplies must be the same as the airflow direction of the installed
fan modules.
AC Power Supply Cords
An AC power cord is not included with the Summit AC power supply. You can purchase AC power
cords for use in the US and Canada from Extreme Networks or from your local supplier. The cord must
meet the requirements listed in
“Power Cord Requirements for AC-Powered Switches and AC Power Supplies”
on page 500

Installing a Summit 450 W or 550 W AC Power Supply
WARNING!
To prevent an electrical hazard, make sure that the AC power cord is not connected to the power supply
before you install the power supply in the power supply bay.
CAUTION
Make sure that the AC power supply circuit is not overloaded. Use proper over-current protection, such as
a circuit-breaker, to prevent over-current conditions.
