Connecting Jsa7500 To A Dc Power Source - Juniper JSA7500 Secure Analytics Hardware Manual

Connecting JSA7500 to a DC Power Source

Before connecting your Juniper Secure Analytics (JSA) appliance to a DC power source:
• Ensure that you have taken the necessary precautions to prevent ESD damage.
• Ensure that you have connected the JSA appliance chassis to earth ground.
Required tools and parts:
• DC power source cables (12-14 AWG) with ends of the wire stripped ~12mm and twisted
• Phillips (+) screwdriver, number 1
CAUTION: Before you connect power to the JSA appliance, attach ground wire in one
of the below configurations to meet the safety requirements and to ensure proper
operation:
• Both power supply ground terminals
• One or both of the chassis ground terminal(s) located to the left of the power supply
modules
• Both power supply ground terminals and one or both chassis ground terminals
You connect DC source power to the JSA appliance by attaching power cables from the external DC
power sources to the terminal studs on the DC power feed faceplates.
WARNING: DC-powered JSA appliances are intended for installation only in restricted
access locations.
WARNING: Before you perform the following procedure, ensure that power is removed
from the DC circuit. To ensure that all power is off, locate the circuit breaker on the
panel board that services the DC circuit, switch the circuit breaker to the OFF position,
and tape the switch handle of the circuit breaker in the OFF position.
To connect the DC source power to the JSA appliance:
1. Ensure that the input circuit breaker is open so that the voltage across the DC power source cable
leads is 0 V, so that the cable leads will not become active while you are connecting DC power.
