7.
Insert the power cord plug into an AC power source outlet.
8.
Dress the power cord appropriately. Verify that the power cord does not block the air
exhaust and access to services gateway components or drape where people could
trip on it.
9.
If the AC power source outlet has a power switch, set it to the on (
|
) position.
10.
Repeat steps 4 through 8 for the second AC power supply.
11.
Verify that the AC and DC LEDs on each power supply are lit green. If the fault status
(!) LED is lit amber, remove power from the power supply, and replace the power
supply (see
“Removing an AC Power Supply from an SRX4200 Services Gateway”
on page 56 ). Do not remove the power supply until you have a replacement power
supply ready. The power supplies must be installed in the services gateway to ensure
proper airflow.
Connecting DC Power to an SRX4200 Services Gateway
Before you begin connecting DC power to an SRX4200 Services Gateway:
•
Ensure that you have taken the necessary precautions to prevent electrostatic discharge
(ESD) damage.
• Ensure that you have connected the chassis to earth ground.
CAUTION: Before you connect power to the services gateway, a licensed
electrician must attach a cable lug to the grounding cable that you supply.
A cable with an incorrectly attached lug can damage the device (for
example, by causing a short circuit).
To meet safety and electromagnetic interference (EMI) requirements and
to ensure proper operation, you must properly ground the services gateway
chassis before connecting power.
Ensure that you have the following parts and tools available:
•
DC power source cables (14–16 AWG) with ring lug (Molex 190700069 or equivalent)
• Phillips (+) screwdriver, number 2
• Multimeter
