Attach the Switch to a Rack or Cabinet

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

• Four-post rack, using the mounting kit provided.
• Two-post rack, using mounting brackets (not provided) to attach the front or the middle of the switch to the posts.

The part number for the provided four-post mounting kit is XN-4P-RMKIT-005. The part number for the two-post mounting kit that is not provided, but can be ordered separately, is XN-2PRMKIT-005.

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

Note

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

Two-Post Rack Mount

Use the following instructions to install the switch in a two-post rack.

1. Set a mounting bracket against the switch housing on one side of the switch.

   Set the flange (ear) flush with the front of the switch, facing the front, for a flush-mount.

   Set the flange (ear) toward the back of the switch, facing the rear, for a mid-mount.

   The following figures illustrate how to attach the brackets for two common mounting options.

   • Flush-Mount: Attaching Short Mounting Brackets shows a flush-mount configuration using a short mounting bracket.
   • Mid-Mount: Attaching Short Mounting Brackets shows a mid-mount configuration using a short mounting bracket.

2. Use the small bracket-mounting screws (provided) to secure the bracket to the switch housing.

   If you are using screws other than the screws that are provided, ensure that the threaded length of the screws is within 4 to 5 cm.

3. Repeat step 1 and step 2 to to attach the other bracket to the other side of the switch.
4. Secure the mounting bracket flanges to the rack, using screws that are appropriate for the rack. (Rack-mounting screws are not provided.)
5. Ground the switch if a grounding lug is present.
   1. At one end of the wire, strip the insulation to expose 1/2 inch (12 mm) of bare wire.
   2. Identify the grounding lug on the back of the switch.
   3. Insert the stripped wire into the grounding lug.
   4. Tighten the retaining screw with a straight-tip torque screwdriver to 20 in-lb (2.25 N m).
   5. Connect the other end of the wire to a known reliable earth ground point at your site.

After the switch is secured to the rack or cabinet, install optional components using the instructions in Install Optional Components.

Four-Post Rack Mount

1. Attach the rack rails to both sides of the switch using the provided rack screws.
2. Attach the rack ears to the front rack posts, using the screws (rack post screws not provided).
3. Slide the rack rails into the rack ears on both sides, and adjust them to the appropriate rack depth.

4. Attach the rack rails to the rear rack posts, using the screws (rack post screws not provided).
5. If a grounding lug is present, ground the switch.
   1. At one end of the wire, strip the insulation to expose 1/2 inch (12 mm) of bare wire.
   2. Identify the grounding lug on the back of the switch.
   3. Insert the stripped wire into the grounding lug.
   4. Tighten the retaining screw with a straight-tip torque screwdriver to 20 in-lb (2.25 N m).
   5. Connect the other end of the wire to a known reliable earth ground point at your site.

After the switch is secured to the rack or cabinet, install optional components using the instructions in Install Optional Components.
