AC Power Circuit Breaker Requirements for the SRX5600 Services Gateway

Each AC power supply has a single AC appliance inlet located on the power supply that requires a dedicated
AC power feed. We recommend that you use a customer site circuit breaker rated for 15 A (250 VAC)
minimum for each AC power supply, or as required by local code. Doing so enables you to operate the
services gateway in any configuration without upgrading the power infrastructure.

SRX5600 Services Gateway DC Power Supply

Each DC power supply consists of one DC input (–48 VDC and return), one 40 A (–48 VDC) circuit breaker,
a fan, and LEDs to monitor the status of the power supply. Two different DC power supply types are
available. Figure 18 on page 55 and Figure 19 on page 56 show the power supplies. Each DC power supply
has a single DC input (–48 VDC and return) that requires a dedicated facility circuit breaker.
For high-capacity power supplies, we recommend that you provision 60 A or 70 A per feed, depending
on the selected DIP switch setting.
