NetShelter SX Networking Enclosure — Unpacking, Installation, and Customization Manual18

Installing Equipment

Warning: To prevent the enclosure from tipping over after equipment installation:

• Make sure you have secured the enclosure to the floor before installing equipment.

• Install the heaviest equipment first toward the bottom of the enclosure to prevent the

enclosure from becoming top-heavy.

• Do not extend equipment on sliding rails until you have installed three or more pieces of

similar-sized equipment or until you have installed the stabilizer plate or bolt-down

brackets. Do not extend more than one piece of equipment on sliding rails at a time.

To install rack-mount equipment in the enclosure:

1. Review the equipment manufacturer’s installation instructions.

2. Locate the top and bottom U-space on the vertical mounting rails.

Every third hole on the mounting rails is numbered to indicate the

middle of a U-space.

3. Install the cage nuts on the interior of the vertical mounting rail;

then install the equipment.

How to install a cage nut

Warning: To ensure equipment installs

securely, install cage nuts with tabs

engaging the left and right sides of the

square hole. Do NOT install cage nuts with tabs

engaging the top and bottom of the square hole.

Note: To remove a cage nut, squeeze the sides to release it from the square hole.
