Power On The Dc-Powered Ptx3000 - Juniper PTX3000 Quick Start Manual

Power On the DC-Powered PTX3000

To power on a DC-powered PTX3000:
NOTE: After powering off a power supply, you must wait at least 60 seconds before powering it
on again.
1. Verify that the power supply modules (PSMs) are fully inserted in the chassis and that the captive screw
on the faceplate of each PSM is tightened.
2. Verify that the DC power cables are connected correctly.
3. Verify that an external management device is connected to one of the Routing Engine ports on the
Control Board or the Routing and Control Board (RCB). The auxiliary ports are labeled AUX and the
management console ports are labeled CON.
NOTE: The management Ethernet port labeled HOST/ETHERNET on the Control Board and
MGT on the RCB are not available until after the initial software configuration. You can monitor
the startup process during the initial installation by using devices connected to the AUX or CON
ports.
4. Turn on the power to the external management device.
5. Switch on the customer-site circuit breakers to provide voltage to the DC power source cables. Follow
your site's procedures.
6. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
the ESD point on the chassis.
7. Verify that the input 1 and input 2 LEDs on the PSM faceplate are lit steadily green, indicating that the
inputs are receiving input voltage.
8. Switch the power switch on one PSM to the on position (|).
