SRX650 Services Gateway Power Supply
The SRX650 Services Gateway uses either one AC or one DC power supply unit (PSU). The services gateway is equipped with one AC power supply (see Figure 1). A second PSU is optional (sold separately). A second PSU can be used to meet power requirements exceeding the wattage provided by a single PSU in a nonredundant configuration by using two power supplies in a system using more power than a single PSU provides. A second AC or DC power supply can be used with its matching type of power supply to provide redundancy and load-sharing to the services gateway and its components. If one power supply fails or is removed, the remaining power supply redistributes 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. See Figure 2 for a diagram of the DC power supply.
 | Caution: Do not mix AC and DC power supplies within the same services gateway. Damage to the device might occur. |
All power supplies are hot-swappable and support single or dual redundant power supply versions. Each power supply is cooled by the system’s fans.

The power supplies produce and distribute different output voltages to the services gateway components according to their voltage requirements.
The available power supply components are listed in Table 1.
Table 1: Component Power Output/Consumption
Power Supply | Output/Consumption |
|---|---|
645 W AC power supply | This power supply can provide:
Note: Using the two power supply option operating as nonredundant for up to 510 W @PoE power, the administrator has the ability to prioritize the PoE ports that will receive power if an outage should occur to either the power source or to one of the power supplies. |
645 W DC power supply | This power supply can provide:
Note: Using the two power supply option operating as nonredundant for up to 510 W @PoE power, the administrator has the ability to prioritize the PoE ports that will receive power if an outage should occur to either the power source or to one of the power supplies. |
