Connecting the OCX1100 to Power

 

Connecting AC Power to an OCX1100 Switch

The AC-powered models of (see OCX1100 Switch Models) OCX1100 switches support 460 W AC power supplies. After you install at least one power supply, you can connect power to the switch.

Caution

Do not install:

  • AC and DC power supplies in the same chassis.

  • AC power supplies in DC switch models or DC power supplies in AC switch models.

  • Power supplies with different airflow labels (AIR IN (AFI) and AIR OUT (AFO)) in the same chassis.

  • Power supplies and fan modules with different airflow labels (AIR IN (AFI) and AIR OUT (AFO)) in the same chassis.

Before you begin connecting AC power to an OCX1100 switch:

  • Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).

  • Ensure that you have connected the device chassis to earth ground, if required by your site guidelines or installation. A ground connection to the protective earthing terminal is not required for an AC-powered device. The AC power cords provide adequate grounding when you connect the power supply in the switch to a grounded AC power outlet by using the AC power cord appropriate for your geographical location (see AC Power Cord Specifications for an OCX1100 Switch).

    Caution

    For installations that require a separate grounding conductor to the chassis, have a licensed electrician complete this connection before you connect the switch to power.

  • Install the power supply in the chassis. For instructions on installing a power supply in an OCX1100 switch, see Installing an AC Power Supply in an OCX1100 Switch.

Ensure that you have a power cord appropriate for your geographical location (provided).

Note

Each power supply must be connected to a dedicated power source outlet.

To connect AC power to an OCX1100 switch:

  1. Attach the grounding strap to your bare wrist and to a site ESD point.
  2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure. If only one power supply is installed, ensure that a cover panel is installed over the second power supply slot.
  3. Locate the power cord shipped with the switch; the cords have plugs appropriate for your geographical location. See AC Power Cord Specifications for an OCX1100 Switch.
  4. Insert the coupler end of the power cord into the power port of the power supply module. See Figure 1.

  5. If the AC power source outlet has a power switch, set it to the off (O) position.
  6. Insert the power cord plug into an AC power source outlet.
  7. If the AC power source outlet has a power switch, set it to the on (|) position.
  8. Verify that the LEDs on each power supply are lit green.

    If the LED is lit amber, remove power from the power supply, and replace the power supply (see Removing an AC Power Supply from an OCX1100 Switch). Do not remove the power supply until you have a replacement power supply ready: the power supplies or a cover panel must be installed in the switch to ensure proper airflow.

    Caution

    We recommend that you install either a replacement power supply or a cover panel in an empty power supply slot to prevent chassis overheating and dust accumulation.

Connecting DC Power to an OCX1100 Switch

The DC-powered models of (see OCX1100 Switch Models) OCX1100 switches support 800 W DC power supplies. After you install at least one power supply, you can connect power to the switch.

Caution

Do not install:

  • AC and DC power supplies in the same chassis.

  • AC power supplies in DC switch models or DC power supplies in AC switch models.

  • Power supplies with different airflow labels (AIR IN (AFI) and AIR OUT (AFO)) in the same chassis.

  • Power supplies and fan modules with different airflow labels (AIR IN (AFI) and AIR OUT (AFO)) in the same chassis.

Before you begin connecting DC power to an OCX1100 switch:

Ensure that you have the following parts and tools available:

  • A DC power cord (provided)

  1. Attach the grounding strap to your bare wrist and to a site ESD point.
  2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure. If only one power supply is installed, ensure that a cover panel is installed over the second power supply slot.
  3. Locate the DC power cord shipped with the switch.
  4. Insert the coupler end of the power cord into the power port of the power supply module. See Figure 2.

  5. If the DC power source outlet has a power switch, set it to the off (O) position.
  6. Insert the power cord plug into a DC power source outlet.
  7. If the DC power source outlet has a power switch, set it to the on (|) position.
  8. Verify that the LEDs on each power supply are lit green.

    If the LED is lit amber, remove power from the power supply, and replace the power supply (see Removing a DC Power Supply from an OCX1100 Switch). Do not remove the power supply until you have a replacement power supply ready: the power supplies or a cover panel must be installed in the switch to ensure proper airflow.

    Caution

    We recommend that you install either a replacement power supply or a cover panel in an empty power supply slot to prevent chassis overheating and dust accumulation.
