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.
Table 12: Power Supply Type Summary
Power
Distribution Redundancy Maximum Output Input Condition (If Any) Power Supply Type
Shared 3+1 1700 W AC standard-capacity
Zoned 2+2 1700 W One AC input AC high-capacity
4100 W Two AC inputs
1700 W DC standard-capacity
1700 W One DC input DC high-capacity
4100 W Two DC inputs
NOTE: The services gateway must be running Junos OS Release 10.4 or later in order to use
high-capacity AC power supplies. The services gateway must be running Junos OS Release
12.1X44-D10 or later in order to use high-capacity DC power supplies.
Redundant power supplies are hot-removable and hot-insertable. Each power supply is cooled by its own
internal cooling system.
NOTE: Devices configured from the factory 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.
