Juniper PWR-MX480-2400-DC-S network switch component Power supply

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 1 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 75A per feed, depending on the selected DIP switch setting.
