SRX5800 Services Gateway High-Capacity AC Power Supply
High-capacity AC power supplies provide a maximum of 4100 W of power each. Two high-capacity power
supplies are required, and you can install four high-capacity power supplies for redundancy. Each
high-capacity AC power supply has two corresponding AC appliance inlets: one located in the chassis
directly above the power supply and one located near the top edge of the power supply itself. For each
power supply, you connect one power cord to the inlet on the chassis above the power supply and one
power cord to the inlet on the power supply itself. Each inlet you connect requires a dedicated AC power
feed and a dedicated 15 A (250 VAC) circuit breaker. See Figure 17 on page 53 .
NOTE: The services gateway cannot be powered from standard-capacity and high-capacity AC
power supplies simultaneously. The one exception is during the process of replacing
standard-capacity AC power supplies with high-capacity AC power supplies, when it is permissible
to have both types installed briefly.
