Attach the Switch to a Rack or Cabinet

The 7520 Series switch can be attached to a standard 19-inch equipment rack, in either of the following ways:

To attach a switch to a two-post rack, a four-post rack, or a cabinet, follow these steps.

Note

Note

Take care to load the rack so that it is not top-heavy. Start installing equipment at the bottom and work up.

Four-Post Rack Mount

A four-post rack-mounting kit is included in the box with your switch. The kit contains an instruction sheet, along with the following components:
  • Two mounting brackets, known as inner member in the instruction sheet. These pieces attach directly to both sides of the switch housing.
  • Two slider assemblies, one for each side of the switch. Each slider assembly consists of an outer piece that is secured to the rack and a sliding rail to which you will attach the corresponding mounting bracket. These pieces are known on the instruction sheet as the outer member and intermediate member.
  • Mounting ears - Black rack ears with a thumb screw in the middle (2 count)
  • Black mounting ear screws (6 count)

To attach your switch to a four-post rack, follow these steps:

  1. Separate the inner sliding rails from the outer rails by extending the rails and pulling on the disconnect latch. Note which direction the sliding rails slide from the outer rails for correct installation.

Two-Post Rack Mount

You can attach the switch to a two-post rack in either of two configurations:
  • Front mount
  • Mid-mount

The side of the switch has different sets of holes for attaching mounting brackets in either configuration.

Brackets for a two-post mount are not included in the box with the switch. However, they can be ordered separately using part number XN-2P-RKMT299.

To attach the switch to a two-post rack, follow these steps:

  1. On one side of the switch, attach one of the short mounting brackets to the device.
    1. For a front mount, position the bracket over the holes so that the flange (ear) is even with the front of the device, as shown in the figure below:

      Attaching a Short Mounting Bracket (Ear): Front of Switch
      Attaching a Short Mounting Bracket (Ear): Front of Switch
    2. For a mid-mount, position the bracket so that the flange (ear) is positioned slightly more than halfway between the front and back of the device, as shown in figure below:
      Click to expand in new window
      Attaching a Short Mounting Bracket (Ear): Middle of Switch

    3. Use four small mounting screws (provided) to attach the bracket to the device.
  2. Attach the other short mounting bracket to the other side of the device, as you did in step 2.
  3. Secure the brackets to the rack posts using rack-mounting screws that are appropriate for the rack (not provided).

If the switch comes with installed power supplies, skip to the topic: Turn on the Switch.

If the switch does not have an installed power supply, install one or two power supplies using the instructions in Install Internal Power Supplies.
