Powering On The Dc-Powered Ptx5000 With High Capacity Dc Pdus And High Capacity Dc Psms - Juniper PTX5000 Hardware Manual

Powering On the DC-Powered PTX5000 with High Capacity DC PDUs
and High Capacity DC PSMs
To power on the DC-powered PTX5000 with High Capacity DC PDUs and High Capacity DC PSMs:
NOTE: After powering off a power supply, you must wait at least 60 seconds before powering it
on again.
1. Verify that the power distribution units (PDUs) and power supply modules (PSMs) are fully inserted
in the chassis and that the captive screws on the faceplates are tightened.
2. Verify that an external management device is connected to one of the Routing Engine ports on the
Control Board (AUXILIARY or CONSOLE).
NOTE: The management Ethernet port labeled HOST/ETHERNET on the Control Board is
not available until after the initial software configuration. You can monitor the startup
process during the initial installation using devices connected to the AUXILIARY or
CONSOLE ports.
3. Turn on power to the external management device.
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. Switch the power switch on one of the PDUs to the on (|) position.
7. Verify that the green PDU OK LED is lit steadily green, indicating that the inputs are receiving
power.
8. Verify that the -1 and -2 LEDs for each installed PSM are lit green. Also check the input 1 OK, input
2 OK, output OK, and fault
(
) LEDs on each PSM.
NOTE: The -1 and -2 LEDs are lit depending on the number of PSMs connected to each
PDU. A minimum of three PSMs are required out of a maximum of eight per PDU. Also, each
PSM has LEDs indicating input and output status.
