• RPF1 (Reverse Polarity Feeder 1) (flashing yellow)—The PDU (Feeder 1) is
miswired. See
Step 8 of the “Removing and Replacing a DC PDU” procedure
on page 5-28 . During normal operation, this indicator remains off.
• RP21(Reverse Polarity Feeder 2) (flashing yellow)—The PDU (Feeder 2) is
mis-wired. See
Step 8 of the “Removing and Replacing a DC PDU”
procedure on page 5-28 . During normal operation, this indicator remains off.
• Fail (red)—Lights in conjunction with the following indicators (which flash)
to show the type of power supply failure:
– F1LO
– F2LO
– OC
– OT
• OC (Over Current) (flashing red)—Indicates the input or output current has
exceeded its limit and that an overload or short circuit 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 an overtemperature condition. Verify that all fans
in the blower module are operating properly.
– If all the blower module fans function, replace the power supply.
• 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. If there is a power supply failure, the INOK indicator shuts off.
