Connecting the JATP700 to Power

Connecting the JATP700 Appliance to Ground

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the device chassis to earth ground, if required by your site guidelines or installation.

Grounding for the JATP700 appliance is provided through the power supply ground. Ensure that you connect the AC power supply module in the appliance to a grounded AC power outlet by using an AC power cord (with the grounding pin) appropriate for your geographical location.

Connecting AC Power Source to the JATP700 Appliance

Before you connect AC power to the JATP700 appliance:

  • Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage.

  • Ensure that you have connected the JATP700 appliance chassis to earth ground, if required by your site guidelines or installation.

    CAUTION:

    For installations that require a separate grounding conductor to the chassis, have a licensed electrician complete this connection before you connect the appliance to power. For instructions on connecting earth ground, see Connecting the JATP700 Appliance to Ground.

Required tools and parts:

  • ESD grounding strap

  • Power cord or cords appropriate for your geographical location.

CAUTION:

Before you connect power to the JATP700 appliance, ensure both power supply ground terminals are grounded to meet the safety requirements and to ensure proper operation.

To connect AC power to a JATP700 appliance:

  1. To prevent damage to the equipment caused by static discharge, attach one end of an ESD strap to an ESD point and fasten the other end around your bare wrist.
  2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure.
  3. Locate the power cord or cords shipped with the JATP700 appliance.
  4. Plug the power cord into the AC receptacle on the rear panel as shown in Figure 1.

    If your appliance contains two power supplies, plug each of the power cords into each of the AC receptacles.

    Note:

    Grounding for the appliances is provided through the power supply ground terminal. Ensure that you connect the AC power supply module in the appliance to a grounded AC power outlet by using an AC power cord (with the grounding pin) appropriate for your geographical location.

  5. Plug the other end of the power cord into a wall socket.
  6. Press the Power button on the front panel.
  7. Verify that the status LEDs of the power supply is lit solid green.

Connecting DC Power to the JATP700 Appliance

Before connecting your JATP700 appliance to a DC power source:

  • Ensure that you have taken the necessary precautions to prevent ESD damage.

  • Ensure that you have connected the JATP700 appliance chassis to earth ground, if required by your site guidelines or installation.

    CAUTION:

    For installations that require a separate grounding conductor to the chassis, have a licensed electrician complete this connection before you connect the appliance to power. For instructions on connecting earth ground, see Connecting the JATP700 Appliance to Ground.

Required tools and parts:

  • DC power source cables (12-14 AWG) with ends of the wire stripped ~12 mm and twisted

  • Phillips (+) screwdriver, number 1

CAUTION:

Before you connect power to the JATP700 appliance, ensure it is grounded in one of the below configurations to meet the safety requirements and to ensure proper operation:

  • Both power supply ground terminals

  • One or both of the chassis ground terminal(s) located to the left of the power supply modules

  • Both power supply ground terminals and one or both chassis ground terminals

You connect a DC power source to the JATP700 appliance by attaching power cables from the external DC power sources to the terminal studs on the DC power feed faceplates.

Warning:

DC-powered JATP appliances are intended for installation only in restricted access locations.

Warning:

Before you perform 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, and tape the switch handle of the circuit breaker in the OFF position.

To connect the DC source power to the JATP700 appliance:

  1. Ensure that the input circuit breaker is open so that the voltage across the DC power source cable leads is 0 V, and so that the cable leads will not become active while you are connecting DC power.
  2. Connect the black wire to the -48 V terminal block and red wire to the RTN terminal block on the back panel of the JATP700 appliance.
  3. Use the terminal screws to secure the power source cables to the power feed on the JATP700 appliance.
  4. Attach the plastic safety cover.
  5. Close the input circuit breaker.

    The device powers on as soon as power is provided to the power supply.

Powering Off the JATP700

You can power off the JATP700 appliance in one of the following ways:

  • Graceful shutdown—Press and immediately release the Power button. Or

    You can run the following command in the server configuration mode:

    shutdown

  • Forced shutdown—Press the Power button, and hold it for five seconds. Use this method only if the appliance is not responding to the graceful shutdown method.
