SRX5600 Services Gateway AC Power Configurations
The services gateway supports either the low-line (110V) AC power configuration or the high-line (220V) AC power configuration.
- In the low-line (110 V) AC power configuration, the services gateway contains three or four AC power supplies (see ), located horizontally at the rear of the chassis in slots PEM0 through PEM3 (left to right). Each AC power 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 services gateway contains two or four AC power supplies (see ), located horizontally at the rear of the chassis in slots PEM0 through PEM3 (left to right). In a high-line AC power configuration, each AC power supply provides power to all components in the services gateway. When two or more 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. Two power supplies provide the maximum configuration with full power for as long as the device is operational. In the two-PEM high-line configuration, slots PEM0 and PEM1 or PEM2 and PEM3 are used. The high-line configuration requires two power supplies, with the third and fourth providing redundancy.
