–F1LO (Feeder 1 Low)

–F2LO (Feeder 2 Low)

–OC (Over Current)

–OT (Over Temperature)

•OC (over current) (flashing red)—Indicates the input or output current has exceeded its limit and that an overload or short has occurred.

–Set the power supply switch to off (0) and then back to the on (1) position.

–If the indicator is still flashing, eject and reseat the power supply.

–If the indicator is still flashing, replace the power supply.

•OT (over temperature) (steady or flashing red)—Indicates that the power supply is in an overtemperature condition, causing a shut-down to occur.

–Flashing red indicates a locked power supply fan. Replace the power supply.

–Steady red indicates a true overtemperature condition. Make sure that all blower module fans are operating properly.

Replace the power supply if the blower module is operating properly.

Replace the blower module if one or more of the blower module fans are not working.

•INOK (green)—Indicates that the power supply is operating normally, and the source DC voltage is within the nominal operating range of –48 to –60 VDC. This indicator lights when the power switch is set to the on (1) position.
