HP recommends a minimum of two power supplies. For a list of power supply specifications, see "Power Specifications" on page 71. To determine the status of a power supply: 1. Check the LED indicators on the power supply. Refer to Table 7 on page 62 for LED interpretation. 2. Check the power supply status using the psShow command. The power supply status displays OK, absent, or faulty. If a power supply is absent or faulty, contact HP support to order replacement parts, as necessary. For additional information about the psShow command, refer to the hp StorageWorks fabric os reference. CAUTION To protect against AC power failure, HP recommends a minimum of one power supply in slot #1 or slot #3, and one in slot #2 or #4. If only two power supplies are installed and they are not configured in this manner, unplugging a single power cable will power down the entire chassis. Disassembling any part of the power supply voids the part warranty and regulatory certifications. There are no user-serviceable parts inside the power supply.
