Fast Track to Rack Installation and Power

This procedure guides you through the simplest steps for the most common installation to get your NFX250 device in a rack and connect it to power.

Install the NFX250 in a Rack

You can install the NFX250 device on a desktop or other level surface, on two-post racks or four-post racks. We’ll walk you through the steps to install an NFX250 device in a two-post rack.

Before you install, review the following:

Mount the NFX250 Device

To mount the device:

  1. Place the device on a flat, stable surface.
  2. Align a front bracket (either flush with the front of the chassis or 2-in.-recessed from the front of the chassis) along the side panel of the device chassis. Align the two holes in the front of the brackets with the two holes on the front of the side panel.
    Note:

    Each side of the chassis has twelve holes for attaching the front-mounting brackets to the device.

    Six holes on the chassis side align with six holes in the front bracket when the front bracket is mounted flush with the chassis front or recessed 2 in. from the front of the chassis.

  3. Insert M4x6-mm Phillips flat-head mounting screws into the two aligned holes and tighten the screws. Ensure that the remaining two holes in the front bracket are aligned with the two holes in the side panel. See Figure 1.

  4. Insert M4x6-mm Phillips flat-head mounting screws into the remaining two holes in the front bracket and tighten the screws.
  5. Repeat steps 2 through 4 for attaching the front bracket to the other side of the chassis.
  6. Have one person grasp both sides of the device, lift the device, and position it in the rack, aligning the front bracket holes with the threaded holes in the front post of the rack. Align the bottom hole in both the front-mounting brackets with a hole in each rack rail, making sure the chassis is level. See Figure 2.

  7. Have a second person secure the front of the device to the rack by using the appropriate screws for your rack.
  8. Slide the rear mounting-blades into the front-mounting brackets.
  9. Attach the rear mounting-blades to the rear post by using the appropriate screws for your rack. Tighten the screws.
  10. Ensure that the device chassis is level by verifying that all the screws on the front of the rack are aligned with the screws at the back of the rack.

Connect to Power

To connect the NFX250 device to AC power, you must do the following:

Ground the NFX250 Device

To ground the NFX250 device, do the following:

  1. Connect one end of the grounding cable to a proper earth ground, such as the rack in which the device is mounted.

  2. Place the grounding lug attached to the grounding cable over the protective earthing terminal. See Figure 3.

  3. Secure the grounding lug to the protective earthing terminal with the washers and screws.

  4. Dress the grounding cable and ensure that it does not touch or block access to other device components.

    Warning:

    Ensure that the cable does not drape where people could trip over it.

Connecting AC Power to an NFX250 Device

Ensure that you have the following parts and tools available:

  • A power cord appropriate for your geographical location

  • A power cord retainer clip

CAUTION:

NFX250 device gets additional grounding when you plug the power supply in the device into a grounded AC power outlet by using the AC power cord appropriate for your geographical location (see AC Power Cord Specifications for an NFX250 Device).

The power supply in an NFX250 device is located on the rear panel.

To connect AC power to the device:

  1. Squeeze the two sides of the power cord retainer clip and insert the L-shaped ends of the wire clip into the holes in the bracket on each side of the AC power cord inlet on the rear panel.

    The power cord retainer clip extends out of the chassis by 3 in.

  2. Locate the power cord or cords shipped with the device; the cords have plugs appropriate for your geographical location. See AC Power Cord Specifications for an NFX250 Device.
    Warning:

    Ensure that the power cord does not drape where people can trip on it or block access to switch components.
  3. Insert the coupler end of the power cord into the AC power cord inlet on the rear panel.
  4. Push the power cord into the slot in the adjustment nut of the power cord retainer clip. Turn the nut until it is tight against the base of the coupler and the slot in the nut is turned 90° from the top of the device.
  5. If the AC power source outlet has a power switch, set it to the OFF (0) 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.
Note:

The retainer brackets on your switch might be above and below the power inlet rather than on either side.
