Connecting power to the SRX1600 involves numerous steps and safety precautions to prevent equipment damage and personal injury.

Note:

To meet the safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the SRX1600 to an earth ground before you connect it to power.

Connect Earth Ground to the SRX1600

Note:

Before you connect an earth ground to the protective earthing terminal of the SRX1600, ensure that a licensed electrician attaches an appropriate grounding terminal to the grounding cable you supply. Using a grounding cable with an incorrectly attached terminal can damage the device.

Before connecting the device to an earth ground, ensure that you have the following parts and tools:

An electrostatic discharge (ESD) grounding strap.
2-hole protective earthing terminal.
Grounding cable for your device—The grounding cable must be 6 AWG (4.11 mm²) stranded wire and rated 90 °C or per local electrical code.
Grounding 2-hole terminal for your grounding cable—This attaches to the chassis grounding point located on the rear of the device.
A Phillips screwdriver to tighten the screw.

The Panduit LCD6-14A-L terminals, or equivalent are sized for 6 AWG (4.11 mm²) cables. The 6 AWG (4.11 mm²) stranded wire should be rated 90 °C or per local electrical code. We recommend that you install heat-shrink tubing insulation around the crimped section of the power cables and lugs.

To ground the SRX1600, connect a grounding cable to earth ground. Attach the grounding cable to the chassis grounding point located on the rear of the device. Under all circumstances, use this grounding connection to ground the chassis.

To ground the device:

Wrap and fasten one end of the ESD grounding strap around your wrist and connect the other end to the ESD point on the chassis.
Ensure that all grounding surfaces are clean and brought to a bright finish before making the grounding connections.
Connect the grounding cable to a proper earth ground, such as the rack in which you mount the device.
Using a Phillips screwdriver, remove the two M5 screws from the grounding point on the rear of the chassis.

Place the grounding cable terminal attached to the grounding cable over the grounding point.
Secure the grounding cable terminal to the grounding point with the M5 screws removed earlier.
Figure 2: Connect the Grounding Cable to the SRX1600
Verify that the grounding cable does not touch or block access to the device components. Make sure that it does not trail across the floor where people could trip over it.

Note:
Ensure that the device is permanently connected to ground during operation.

Connect AC Power to the SRX1600

The AC power supply units (PSUs) in an SRX1600 are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace the PSUs without powering off the device or disrupting its functions.

CAUTION:

You must not mix AC and DC power supplies in the same chassis.

Before you begin to connect AC power to the device:

Ensure that you have connected the chassis to an earth ground.

CAUTION:
Before you connect power to the device, a licensed electrician must attach a cable terminal to the grounding and power cables that you supply. A cable with an incorrectly attached terminal can damage the device (for example, by causing a short circuit).

To meet the safety and EMI requirements and to ensure proper operation, you must connect the chassis to an 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 device chassis to connect to the earth ground. The device gains additional grounding when you plug the PSU in the router to a grounded AC power outlet. Use the AC power cord appropriate for your geographical location.
Ensure that you have a power cord appropriate for your geographical location available to connect AC power to the device.
Read AC Power Electrical Safety Guidelines and Action to Take After an Electrical Accident.
Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage.
Ensure that you have an ESD grounding strap.
If not already installed, install the power supplies in the device.

To connect AC power to an SRX1600:

Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the device.
Ensure that you fully insert the power supplies into the chassis.
Locate the AC power cords shipped with the SRX1600; the cords have plugs appropriate for your geographical location. See Table 5.
Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate.
Push the power cord retainer onto the power cord (see Figure 3).
Figure 3: Connect AC Power Cord
Repeat step 4 and step 5 to insert the second power cord.
If the AC power source outlet has a power switch, set it to the off (0) position.
Insert the power cord plug into an AC power source outlet.

Note:
Connect each power supply to a dedicated AC power feed and a dedicated 2-pole external circuit breaker. We recommend that you use a 10 A (250 VAC), or as permitted by the local code.
If the AC power source outlet has a power switch, set it to the on (|) position.

Connect DC Power to the SRX1600

You connect DC power to the firewall by attaching power cables from the external DC power sources to the terminal studs on the power supply faceplates.

CAUTION:

You must not mix AC and DC power supplies in the same chassis.

Warning:

Before you connect power to the firewall, a licensed electrician must attach appropriate cable termials to the grounding and power cables that you use. A cable with an incorrectly attached terminal 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 chassis before connecting power. See Connect Earth Ground to the SRX1600 for instructions.

Warning:

Before performing the following procedure, ensure that you remove the power 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 (0), and tape the switch handle of the circuit breaker in the OFF position.

The power cables for the DC PSUs are rated 16AWG. To connect the DC source power cables to the firewall for each PSU:

Switch off the dedicated facility circuit breakers. Ensure that the voltage across the DC power source cable leads is 0 V. You must ensure that that the cable leads do not become active during installation.
Install heat-shrink tubing insulation around the power cables:
1. Slide the tubing over the portion of the cable where it is attached to the terminal barrel. Ensure that the tubing covers the end of the wire and the barrel of the lug attached to it.
2. Shrink the tubing with a heat gun. Ensure that you heat all sides of the tubing evenly so that it shrinks around the cable tightly.
  
  Note:
  Make sure that you do not overheat the tubing.
  
  Figure 4 shows how to install heat-shrink tubing.
  
  Figure 4: How to Install Heat-Shrink Tubing
Remove the clear plastic cover that protects the terminal studs on the faceplate.
Verify that you have correctly labeled the DC power cables before making connections to the power supply.
In a typical power distribution scheme where the return is connected to chassis ground at the battery plant, you can use a multimeter to verify the ohm output of the -48V and return (RTN) DC cables to chassis ground. The cable with very large resistance (indicating an open circuit) to chassis ground will be -48V. The cable with very low resistance (indicating a closed circuit) to chassis ground will be RTN.

CAUTION:
You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each power supply.
Remove the screws and square washers from the terminals, using a Phillips (+) screwdriver, number 2.
Secure each power cable ring terminal to the terminals with the square washers and the screws. Apply between 23 in.-lb (2.6 Nm) and 25 in.-lb (2.8 Nm) of torque to each screw.
- Secure each positive (+) DC source power cable ring terminal to an RTN terminal.
- Secure each negative (–) DC source power cable ring terminal to a -48V (input) terminal.
Figure 5: Connecting the DC Power Cables

Note:
Connect each power cable to a dedicated external circuit breaker. We recommend that you use a 10 A (80 VDC), or as permitted by the local code.
Replace the clear plastic cover over the terminal studs on the faceplate.
Verify that the power cables are connected correctly. The cables must not touch or block access to firewall components, and they must not cause a tripping hazard.
Switch the circuit breaker on the panel board that services the DC circuit to the ON (|) position.
Connect the power cables to the external DC power source. If the external DC power source has a switch, set it to the ON (|) position.

Power Off the SRX1600

You can power off the firewall in any of the following two ways:

Graceful shutdown—Press and immediately release the Power button. The device begins gracefully shutting down the operating system (OS) and then powers itself off.

CAUTION:
Use the graceful shutdown method to power off or reboot the firewall.
Forced shutdown—Press the Power button and hold it for ten seconds. The device immediately powers itself off without shutting down the OS.

CAUTION:
Use the forced shutdown method as a last resort to recover the firewall if the firewall OS is not responding to the graceful shutdown method.

To remove power completely from the firewall, unplug the AC power cord.

After powering off a power supply, wait for at least 60 seconds before turning it back on. After powering on a power supply, wait for at least 10 seconds before turning it off.

When the system is completely powered off and you turn on the power supply, the firewall starts as the power supply completes its startup sequence. If the firewall finishes starting and you need to power off the system again, first issue the request vmhost halt command.

Note:

The fans in the power supply continue to rotate even after you power off the SRX1600. To stop the fans, remove the power cord from the power supply. The fans will stop in a few seconds.

After turning on the power supply, it can take up to 60 seconds for status indicators—such as the PWR LED 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.
