4. Switch on the customer-site circuit breakers to provide voltage to the DC power source cables.
5. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
6. Verify that the green –48 V 120 A LEDs on the PDU faceplate are lit steadily green, indicating that
the inputs are receiving power.
7. Switch all the circuit breakers on one of the PDUs to the on (|) position.
8. Verify that the green CB ON LEDs on the PDU faceplate are lit steadily. The CB ON LEDs blink
momentarily, then light steadily to indicate that the circuit breakers are on.
NOTE: After a PDU is powered on, it can take up to 60 seconds for status indicators—such
as the LEDs on the PDU and PSMs, the command output displays, and messages on the
LCD display on the craft interface—to indicate that the PDU and PSMs are functioning
normally. Ignore error indicators that appear during the first 60 seconds.
9. Move the OUTPUT power switch on the PDU to the on (|) position.
10. Verify that the PDU OK LED on the PDU faceplate is lit steadily and that the FAULT LED is off,
indicating that the PDU is correctly installed and is functioning properly.
NOTE: If the PDU OK LED does not light steadily, repeat the installation and cabling
procedures.
11. Check the LEDs on the PSMs. For each PSM, verify that the Input OK and Output OK LEDs are lit
steadily green, and that the Fault LED is off.
NOTE: If the Input OK and Output OK LEDs do not light steadily or if the FAULT LED is lit,

12. On the external management device connected to the Routing Engine, monitor the startup process
to verify that the system has booted properly.
13. Repeat steps 7 through 12 for the other PDU.
NOTE: The Routing Engine boots as the PDU completes its startup sequence. If the Routing
Engine finishes booting and you need to power off the system, see the
PTX5000" on page 299
After powering on a power supply, you must wait at least 60 seconds before powering it off.
