SRX3600 Services Gateway AC Power Supply Overview

 

In an AC power configuration, the services gateway contains two to four AC power supplies, located at the rear of the chassis in slots PEM0 through PEM3. Each power supply provides power to all components in the services gateway. The power supplies share power almost equally within a fully populated system.

Two power supplies are required to meet the services gateway power requirements. Installing a third or fourth AC power supply provides full power redundancy. If one power supply fails or is removed, the remaining power supplies redistribute the electrical load without interruption. The services gateway reassesses the power required to support its configuration and issues errors if the available power is insufficient.
