Juniper SRX4600

NOTE: Each power supply input feed must be connected to a dedicated DC power source outlet.
Before you begin connecting DC power to the services gateway:
•
Ensure that you have taken the necessary precautions to prevent ESD damage (see “Prevention of
Electrostatic Discharge Damage” on page 181).
•
Ensure that you have connected the services gateway chassis to earth ground.
CAUTION: To meet safety and electromagnetic interference (EMI) requirements
and to ensure proper operation, you must connect the services gateway to earth
ground before you connect it to power. For installations that require a separate
grounding conductor to the chassis, use the protective earthing terminal on the
services gateway chassis to connect to earth ground. For instructions on connecting
an SRX4600 Services Gateway to ground using a separate grounding conductor,
see “Connecting Earth Ground to an SRX4600 Services Gateway” on page 74.
•
Install the power supply in the chassis. See “Installing the SRX4600 Services Gateway DC Power Supply”
on page 97.
Ensure that you have the following parts and tools available to connect DC power to the services gateway:
•
Electrostatic discharge (ESD) grounding strap
•
Multimeter
WARNING: Ensure that the power cords do not block access to services gateway
components or drape where people can trip on them.
To connect DC power to the services gateway:
1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the
chassis.
2. Ensure that the power source circuit breaker is open so that the voltage across the DC power source
cable leads is 0 V and that the cable leads do not become active while you are connecting DC power.
3. Verify that the DC power cables are correctly labeled before making connections to the power supply.
