SRX3400 Services Gateway AC Power Supply Overview


In an AC power configuration, the SRX3400 Services Gateway contains one or two AC power supplies, located at the rear of the chassis in slots PEM0 and PEM1. Each power supply provides power to all components in the services gateway. When two power supplies are present, they share power almost equally within a fully populated system.

One AC power supply can meet the services gateway power requirements. Installing a second AC power supply provides full power redundancy. If one power supply fails or is removed, the remaining power supply assumes 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.
