Juniper SRX650 Hardware Guide

2. Insert the plug of the power supply adapter into an AC or DC power source receptacle.
a. Using AC Power supply—Insert the appliance coupler end of the power cord into
the appliance inlet on the power supply and the power cord plug into an external
AC power source receptacle.
b. Using DC power supply—Connect DC power cables to the A+ and A- terminals and
the other ends to an external DC power source. If you have two DC power sources
and wish to deploy A/B feed redundancy for the services gateway, also connect
DC power cables to the B+ and B- terminals and the other ends to an external DC
power source.
CAUTION: You must ensure that power connections maintain the
proper polarity. The power source cables might be labeled (+) and (–)
toindicatetheir polarity. There is no standard colorcoding forDC power
cables. The color coding used by the external DC power source at your
site determines the color coding for the leads on the power cables that
attach to the terminals on the power supply.
3. Turn on the power to the AC or DC power receptacle.
The device starts automatically as the power supply completes its startup sequence.
The POWER LED (on the front panel of the chassis) lights during startup and remains
on steadily when the services gateway is operating normally.

Powering Off the SRX650 Services Gateway
You can use any of the following methods to power off the services gateway:
•
Issue the request system halt CLI command (recommended method). Wait until a
message appears confirming that the operating system has halted. To remove power
completely from the services gateway, unplug the AC power cord or DC power supply
cable.
•
Press the Power button on the front of the services gateway and hold it for 4 seconds.
The services gateway begins gracefully shutting down the operating system, the
Services and Routing Engine (SRE) and any Gigabit-Backplane Physical Interface
Modules (GPIMs), and then powers itself off. To remove power completely from the
services gateway, unplug the AC power cord or DC power supply cable.
