Connecting the SRX550 HM to Power
Connecting the SRX550 HM Grounding Cable
You ground the services gateway by connecting a grounding cable to earth ground and then attaching it to the chassis grounding points located on the right side of the device (if you are facing the front of the chassis).
You must install the SRX550 High Memory Services Gateway in a restricted-access location and ensure that the chassis is always properly grounded. The SRX550 High Memory Services Gateway has a two-hole protective grounding terminal provided on the chassis. Under all circumstances, use this grounding connection to ground the chassis. For AC-powered systems, you must also use the grounding wire in the AC power cord along with the two-hole grounding lug connection. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal.
Ensure that you have the following parts and tools available:
-
Phillips (+) screwdrivers, numbers 1 and 2
-
Two M5 grounding screws
-
Grounding cable
-
Cable lug (for example, Panduit LCC6-10A-L)
Before services gateway installation begins, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the services gateway (for example, by causing a short circuit).

Connecting the SRX550 High Memory Services Gateway to the AC Power Source
Do not mix AC and DC power supplies within the same services gateway because this can damage the device.
A 645 W AC power supply with PoE support ships with the SRX550 High Memory Services Gateway. You connect AC power to the services gateway by attaching the power cord from the AC power source to the AC appliance inlet located on the power supply. The power cord is not provided.
To connect the services gateway to an AC power supply:
You need an electrostatic discharge (ESD) grounding wrist strap while connecting the services gateway to an AC power supply.
The services gateway must be connected to earth ground during normal operation. The protective earthing terminal on the side of the chassis is provided to connect the services gateway to ground.
We recommend using a surge protector for the power connection.
Connecting the SRX550 High Memory Services Gateway to a DC Power Source
Do not mix AC and DC power supplies within the same services gateway. Damage to the device might occur.
A 645 W DC power supply with PoE support is available for the SRX550 Services Gateway.
Before performing 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 (O), and tape the switch handle of the circuit breaker in the off position.
You connect DC power to the device by attaching power cables from the external DC power sources to the terminals on the power supply faceplate. You must provide the power cables.
The power supply has two sets of terminals, to accommodate a redundant DC power feed. If one feed fails, the services gateway draws its power from the other feed. The terminals for Feed A are labeled A+ and A- . The terminals for Feed B are labeled B+ and B-. You do not need to use both feeds; if you only have one DC power source, or if you do not want to use feed redundancy, you can connect just one feed.
To connect the DC source power cables to the services gateway power supply:
The services gateway must be connected to earth ground during normal operation. The protective earthing terminal on the back panel of the chassis is provided to connect the services gateway to ground.
Powering On the SRX550 High Memory Services Gateway
To power on the services gateway:
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 SRX550 High Memory Services Gateway
To power off the services gateway, press the Power button on the front of the services gateway and hold it for 10 seconds. The services gateway immediately shuts down.
Graceful shutdown is not supported on the SRX550 High Memory Services Gateway.
To remove power completely from the services gateway, unplug the AC power cord or DC power supply cable.
After powering off a power supply, wait at least 60 seconds before turning it back on. After powering on a power supply, wait at least 10 seconds before turning it off.
When the system is completely powered off and you turn on the power supply, the services gateway starts as the power supply completes its startup sequence. If the services gateway finishes starting and you need to power off the system again, first issue the request system halt CLI command.
After a power supply is turned on, it can take up to 60 seconds for status indicators—such as the POWER LED (on the front panel of the chassis) and the show chassis command display—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.
When you power off a SRX550 High Memory Services Gateway with a LTE Mini-PIM installed, the LEDs on the LTE Mini-PIM may still be lit. This is because the Power button does not shut off power to the power supplies or the midplane on a SRX550 High Memory Services Gateway. You must remove the power cables or power cords to completely shut down the services gateway.
