AC Power Supply Configurations

The SRX 5600 services gateway supports either the low-line (110V) AC power
configuration or the high-line (220V) AC power configuration.

AC Power Supply LEDs

Each AC power supply faceplate contains three LEDs that indicate the status of the
power supply (see Table 19 on page 29). The power supply status is also reflected
in two LEDs on the craft interface. In addition, a power supply failure triggers the
red alarm LED on the craft interface.

supply provides power to all components in the services gateway. When three
power supplies are present, they share power almost equally within a fully
populated system. Four AC power supplies provide full power redundancy. If
one power supply fails or is removed, the remaining power supplies assume the
entire electrical load without interruption. Three power supplies provide the
maximum configuration with full power for as long as the device is operational.
The low-line configuration requires three power supplies and the fourth power
supply provides redundancy.
In the high-line (220 V) AC power configuration, the SRX 5600 services gateway
contains two or four AC power supplies (see Figure 18 on page 28), located
horizontally at the rear of the chassis in slots
In a high-line AC power configuration, each AC power supply provides power to

State Description
Off AC power input voltage is below 78 VAC.
On AC power input voltage is within 78–264 VAC.
Off DC power outputs generated by the power supply are not within the normal
operating ranges.
On DC power outputs generated by the power supply are within the normal operating
ranges.
