Power supply power specifications for the VSP 4450GSX series switches
The Avaya VSP 4450GSX series switches support two external field replaceable AC and DC power
supplies. One power supply ships with the chassis. You can install a secondary power supply to
provide redundancy, load sharing, and to add Power over Ethernet Plus (PoE+) power budget on
PWR+ models.
AC power supply power specifications
The VSP 4000 4450GSX-PWR+, including the TAA compliant version, supports dual 54V 1000W
Power over Ethernet Plus (PoE+) AC power supplies.
Important:
Ensure that you use only 1000W power supplies (both primary and secondary) on VSP 4000
PWR+ models.
