The AC power supply in a QFX3008-I Interconnect device is a hot-insertable and
hot-removable field-replaceable unit (FRU). Six AC power supplies are installed in the
chassis. All power supplies install in the rear of the chassis in the slots provided at the
bottom. See "Slot Numbering for a QFX3008-I Interconnect Device" on page
Before you install an AC power supply in the device, ensure that you understand how to
