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 9 on page 33).
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 10 on page 34 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.
