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.
Table 12 on page 47 describes the different types of power supplies available.
