Connecting the SRX3400 Services Gateway to an AC Power Source
CAUTION: Do not mix AC and DC power supplies within the same services gateway.
Damage to the device might occur.
You connect AC power to the device by attaching power cords from the AC power
sources to the AC appliance inlets located on the power supplies.
To connect the AC power cords to the device for each power supply:
1. Locate the power cord or cords you will use to connect the device to AC power.
The device is not shipped with AC power cords. You must order them separately
using the model numbers shown in SRX3400 Services Gateway AC Power Cord
Specifications.
2. Insert the appliance coupler end of the power cord into the appliance inlet on
the power supply, as shown in Figure 1.

3. Snap the wire bail on the power supply over the power cord to prevent the power
cord from accidentally disengaging.
4. Insert the power cord plug into an external AC power source receptacle.
NOTE: Each power supply must be connected to a dedicated AC power feed and a
dedicated external circuit breaker. We recommend that you use a 15 A (250 VAC)
minimum, or as permitted by local code.

5. Dress the power cord appropriately. Verify that the power cord does not block
the air exhaust and access to device components or drape where people could
trip on it.
6. Repeat steps 1 through 5 for the remaining power supplies.
NOTE: If power is lost to the services gateway, the Power-On/Power-Off state is
retained. For example, if the services gateway loses power while the device is on,
when power returns, the device will still be in the On state.
