SRX5800 Services Gateway Power System Overview

The SRX5800 Services Gateway uses either AC or DC power supplies. The services gateway is configurable with two to four AC power supplies or two or four DC power supplies. The power supplies connect to the midplane, which distributes the different output voltages produced by the power supplies to the services gateway components, depending on their voltage requirements.

Two different types of AC power supply are available:

All power supplies are hot-removable and hot-insertable. Each power supply is cooled by its own internal cooling system.

Note: Devices configured with DC power supplies are shipped with a blank panel installed over the power distribution modules. Devices configured with AC power supplies have no blank panel.

Caution: The services gateway cannot be powered from AC and DC power supplies simultaneously. The first type of power supply detected by the services gateway when initially powered on determines the type of power supply allowed by the services gateway. All installed power supplies of the other type are disabled by the services gateway. If you install a power supply of the other type while the services gateway is operating, the services gateway disables the power supply and generates an alarm.
