    C3000 and C5000 Power Supply Description

    C3000 and C5000 Controllers ship with dual power supplies. In addition to providing power to the controller, the power supplies provide a fan that helps cool the system. The power supply slots are located on the far-right side of the rear panel of the controller. Power supplies are field-replaceable and hot-swappable.

    The power supplies are controlled by a momentary switch. Pressing the switch reboots the chassis. Holding the switch down forces a hard shutdown.

    A single power supply provides power to all components. One power supply is required. A second power supply provides redundancy. If a power supply in a redundant configuration fails, the operational power supply takes over without interruption and assumes responsibility for the entire power load.

    AC Power Supply Description

    Each AC power supply contains an AC power input, status LED, eject lever, and handle, as shown in Figure 1.

    Each inlet requires a dedicated AC power feed and a dedicated customer site circuit breaker. For existing power supplies, we recommend that you use a minimum 5 A (110 VAC) customer site circuit breaker, or as required by local code.

    DC Power Supply Description

    Each DC power supply contains a single DC power input, status LED, eject lever, and handle, as shown in Figure 1.

    The DC power input (–48 VDC and return) requires a dedicated customer site circuit breaker. We recommend that you use a dedicated customer site circuit breaker rated for 10 A (–48 VDC) minimum, or as required by local code.
