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.

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 DeviceAttaching the Mounting Bracket to the Side Panel of the Device
    Note:

    If you need to mount the device in a recessed position, use the 2-in.-recess front mount brackets from the separately orderable four-post rack-mount kit.

  3. Align the bottom holes in the mounting brackets with holes on the side panels of the device chassis.
  4. Insert mounting screws into the aligned holes. Tighten the screws.
  5. Ensure that the other holes in the mounting brackets are aligned with the holes in the side panels. Insert a screw in each hole and tighten the screws.
  6. Have one person grasp both sides of the device, lift the device, and position it in the rack, aligning the mounting bracket holes with the threaded holes in the rack or cabinet rail. Align the bottom hole in both the mounting brackets with a hole in each rack rail, making sure the chassis is level. See Figure 6.

You can mount an NFX250 device on four posts of a 19-in. rack or cabinet by using the separately orderable four-post rack-mount kit. (The remainder of this topic uses rack to mean rack or cabinet.).

You can mount the device on two posts in either a two-post rack or a four-post rack by using the mounting brackets provided with the device. See Mounting an NFX250 Device on Two Posts in a Rack.

Note:

If you are mounting the device on four posts, ensure that the rack is 21.5 in. through 31.5 in. deep if you will mount the device flush with the rack front and that the rack is 23.5 in. through 32.5 in. deep if you will mount the device 2 in. recessed from the rack front, thus ensuring that the protective earthing terminal is accessible through the opening in the rear mounting-blade.

CAUTION:

If you are mounting multiple units on a rack, mount the heaviest unit at the bottom of the rack and mount the other units from the bottom of the rack to the top in decreasing order of the weight of the units.

To mount the device on four posts in a rack:

  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 7.
