Product Description Power Supplies Redundant, hot-swappable 450-watt power supplies convert wide-ranging AC voltage from an external main to stable DC output and deliver it to the backplane. Each power supply has two internal blowers, an AC receptacle (A in Figure 7), a cam handle (B) with locking screw, and an LED (C). Internal control prevents the rear DC connector from becoming energized when the power supply is removed from the disk enclosure. NOTE: LED position varies. A AC receptacle B cam handle C LED Figure 7 Power Supply Note Although it is possible to operate the disk enclosure on one power supply, it is not recommended. Using only one supply creates a single point of failure. If the power supply fails, the entire enclosure is inaccessible. To maintain high availability, both power supplies should be used at all times, and a failed supply should be replaced as soon as possible. Disk Enclosure Components 29
