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 power supply modules (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 the
FAULT LED is lit, see “Troubleshooting the PTX5000 Power System” on
page 139.
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: TheRoutingEngine boots asthe PDU completesits startupsequence.
If the Routing Engine finishes booting and you need to power off the system,
see the “Powering Off the PTX5000 Packet Transport Switch” on page 98.
After powering on a power supply, you must wait at least 60 seconds before
powering it off.
