Each DC power supply weighs approximately 3.8 lb (1.7 kg) and 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. Each DC power supply requires a dedicated customer
site circuit breaker. For normal capacity power supplies, we recommend a dedicated
circuit breaker rated for 40 A (–48 VDC) minimum, or as required by local code.
For high capacity power supplies, we recommend that you provision 60 A or 70 A per
feed, depending on the selected DIP switch setting.
Figure 14 on page 49 shows the normal capacity DC power supply.
