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.
Figure 54 on page 84 shows the power supply. Each DC power supply has a single DC
input (–48 VDC and return) that requires a dedicated facility circuit breaker.
We recommend that you provision 60 A or 70 A per feed, depending on the selected DIP
switch setting.
