Extreme Networks Power Supply Units for BlackDiamond Switches
BlackDiamond 12800 Series Switches Hardware Installation Guide 34
Specifications
The 700/1200 W AC PSU functions from 90 V to 264 V and 47 Hz to 63 Hz AC Input. Each PSU
provides 700 W to the system if the AC input is in the 110 V low-line output power range and 1200 W
to the system if the AC input is in the 220 V high-line output power range.
A greater number of PSUs 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.
CAUTION
The 700/1200 W AC PSU does not have a switch for turning the unit on and off. Remove the plug from the
electrical outlet to disconnect power to the 700/1200 W AC PSU. Make sure that this connection is easily
accessible.
Make sure that the 700/1200 W AC PSU circuit is not overloaded. Use proper over-current protection, such as a
circuit-breaker, to prevent over-current conditions.
