Methods to Mount an LWC Device

Table 2 lists the methods you can use to mount an LWC device.

Table 2: LWC Device Mounting Methods

Mounting Method

Device Model

Description

Desk or other level surface

  • LWC

On a desk or other level surface by using rubber feet provided with the device.

Two-post rack or cabinet

  • LWC

On two posts in a 19-in. rack or cabinet by using the mounting brackets shipped with the device.

Four-post rack or cabinet

  • LWC

  • On four posts in a 19-in. rack or cabinet by using the separately orderable four-post rack mount kit

  • On two posts in a 19-in. rack or cabinet by using the two-post rack mounting brackets.

The holes in the mounting brackets are placed 1 U (1.75 in. or 4.45 cm) apart so that you can mount the device in any rack or cabinet that provides holes spaced at that distance.

See the Related Documentation for detailed descriptions of the various rack or cabinet mounting options.

Mount an LWC Device on a Desk or Other Level Surface

Before mounting the device on a desk or other level surface:

You can mount an LWC device on a desk or other level surface by using the four rubber feet that are shipped with the switch. The rubber feet stabilize the chassis.

To mount the LWC device on a desk or other level surface:

  1. Remove the device from the shipping carton (see Unpack an LWC Device).
  2. Turn the chassis upside down on the desk or the level surface where you intend to mount the device.
  3. Attach the rubber feet to the bottom of the chassis as shown in Figure 1.
  4. Turn the chassis right side up on the desk or the level surface. Now you have mounted the device.
    Figure 1: Attach Rubber Feet to the LWC Device Attach Rubber Feet to the LWC Device

Mount an LWC Device on Two Posts in a Rack

Before mounting an LWC 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

  • Two mounting brackets and eight mounting screws (provided in the accessory box shipped with the device)

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

You can mount an LWC 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.

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 2.
    Figure 2: Attach the Mounting Bracket to the Side Panel of the Device Attach 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 that the chassis is level. See Figure 3.
    Figure 3: Mount the Device on Two Posts in a Rack Mount the Device on Two Posts in a Rack
  7. Have a second person secure the device to the rack by using the appropriate screws. Tighten the screws.
  8. Ensure that the device chassis is level by verifying that all screws on one side of the rack are aligned with the screws on the other side.

Mount an LWC Device on Four Posts in a Rack or Cabinet

Before mounting the device on four posts in a rack:

Ensure that you have the following parts and tools available:

  • Phillips (+) screwdriver, number 2

  • 12 flat-head M4x6-mm Phillips mounting screws (provided with the four-post rack-mount kit)

  • One pair of front-mounting brackets

  • One pair of rear mounting-blades

  • Screws to secure the front-mounting brackets and the rear mounting-blades to the rack (not provided)

You can mount an LWC 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 Mount an LWC 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. If you want to mount the device 2 in, recessed from the front rack, make sure that the rack is 23.5 in. through 32.5 in. deep.Recessed mounting ensures 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. 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 4.
    Figure 4: Attach the Front-Mounting Bracket to the Device Chassis Attach the Front-Mounting Bracket to the Device Chassis
  4. Insert M4x6-mm Phillips flat-head mounting screws into the remaining two holes in the front bracket and tighten the screws.
  5. Repeat Step 2 through Step 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 that the chassis is level. See Figure 5.
    Figure 5: Mount the Device on the Front Posts in a Rack Mount the Device on the Front Posts in a Rack
  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.
