4 Maintain Power Supply Units The array supports two hot-swappable power supply units. The array is capable of operating with one power supply temporarily, but both power supplies are required to maintain long-term reliability of the array. About Power Supplies The PS Series array receives power from two power supply units (PSUs). The array can run on one supply while the other is in a failed state. Each unit has a 2800W power supply that requires 200-240VAC high AC line power source. Identifying Power Supply Failures You can identify a power supply and cooling module failure by the following methods: • LEDs on the power supply and cooling modules. See Back-Panel Features and Indicators on page 5 for details. • Messages on the console, in the event log, or in the Group Manager GUI Alarms panel. • Group Manager GUI and CLI output. The GUI group member Enclosure tab or the CLI member select member_name show enclosure command shows a power supply and cooling module failure. Note: When viewing the rear of the array, power supply 0 is on the left and power supply 1 is on the right. Power Supply Controls and LEDs The power supplies contain LEDs that indicate their status. AC Power Supply Figure 22 illustrates the features of the power supply. Table 10 describes these features. Figure 22: 2800W Power Supply LEDs 31
