MX480 DC Power Supply Description
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.
Figure 14 on page 56 shows the power supply. Each DC power supply has a single DC input (–48 VDC
and return) that requires a dedicated 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.
