Extreme Networks 1200 W Dc Power Supply - Extreme Networks BlackDiamond 8800 Hardware Install Manual

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
Cable Routing for PoE Devices
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.
Specifications
The 600/900 W AC power supply functions from 90 V to 264 V and 47 Hz to 63 Hz AC Input. Each
power supply provides 600 W to the system if the AC input is in the 110 V low-line output power range
and 900 W to the system if the AC input is in the 220 V high-line output power range.
More installed power supplies are needed to support the load if the low-line power range is used to
power the switch. The software determines the maximum available power required for the switch and
enables the modules accordingly.
