Removing and Replacing a DC PDU
•Input OK (green)—Indicates that the power supply is operating normally, and
the source DC input voltage is within the nominal operating range of
-40.5VDC to -75VDC. This indicator should light when the power supply
switch is set to the On (1) position.
–
If the Input OK indicator remains off after checking all of the power
sources, replace the power supply with a spare.
–
If the spare power supply does not work, replace the PDU.
•Miswire (amber)—Indicates the input wiring is incorrect at the PDU power
connection block.
Correct wiring to the DC power connector block (see Figure 5-24).
Removing and Replacing a DC PDU
The DC PDU does not support online insertion and removal (OIR ) and cannot be
replaced while the system is operating. You must power off the router before
replacing the PDU.
Caution To remove and replace the DC PDU, the system must be powered off. Notify the
network administrator and other appropriate personnel that all routing traffic
stops while the PDU is replaced.
