Mounting an NFX250 Device on Two Posts in a Rack

You can mount an NFX250 device on two posts of a 19-in. rack (either a two-post or a four-post rack).

Note

If you need to mount the device in a recessed position on either a two-post rack or a four-post rack, you can use the 2-in.-recess front brackets provided in the separately orderable four-post rack-mount kit.

Before mounting an NFX250 device on two posts in a rack:

  • Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure.

  • Read General Safety Guidelines and Warnings.

  • Remove the device from the shipping carton.

Ensure that you have the following parts and tools available:

  • Phillips (+) screwdriver, number 2

  • 2 mounting brackets and 8 mounting screws (provided in the accessory box shipped with the device)

  • Screws to secure the chassis to the rack (not provided)

Note

One person must be available to lift the device while another secures the device to the rack.

Caution

If you are mounting multiple devices on a rack, mount a device in the bottom of the rack first and proceed to mount the rest of the devices from bottom to top.

To mount the device on two posts in a rack:

  1. Place the device on a flat, stable surface.
  2. Align the mounting brackets along the front, rear, or center of the side panels of the device chassis depending on how you want to mount the device. For example, if you want to front-mount the device, align the brackets along the front of the side panel. See Figure 5.
    Figure 5: Attaching the Mounting Bracket to the Side Panel of the Device
