Installing an HDF
Context
This section describes how to install the HCDF48PDLC00 hybrid cable distribution frame (HDF) in a 19-inch standard cabinet.
Before installation, ensure that:
- The cabinet has been secured and meets the requirements specified in Checking the Cabinet or Rack.
- The installation position of the HDF has been planned.
- The HDF to be installed has been placed near the cabinet for convenient movement.
- Before the installation, ESD measures have been taken. For example, you are already wearing ESD gloves or an ESD wrist strap.
- The left and right sides of the HDF have been aligned horizontally before it is secured to the cabinet. If not, do not forcibly install the HDF; otherwise, it will be distorted.
Tools and Accessories
- ESD wrist strap or ESD gloves
- Phillips screwdriver
- Flat-head screwdriver
- Floating nuts (four for each HDF)
- M6 screws (four for each HDF)
Procedure
- Wear an ESD wrist strap or ESD gloves. If you wear an ESD wrist strap, ensure that one end of the ESD wrist strap is grounded and the other end is in close contact with your wrist.
- Install floating nuts on the mounting rails of the cabinet.
Determine the installation positions of floating nuts on the mounting rails according to the planned installation position of the HDF. Use a flat-head screwdriver to install four floating nuts on the front mounting rails, two on each side. Align the mounting holes on the mounting brackets with two holes with one hole between them on the mounting rails. Ensure that the floating nuts on both sides are aligned horizontally.
Pay attention to the scale markings on the mounting rails because three adjacent mounting holes may not be 1 U.
- Install the HDF into the cabinet.
- Hold the bottom of the HDF and align the holes on the mounting brackets on both sides of the HDF with the floating nuts on the front mounting rails.
- Hold the HDF with one hand, and use a Phillips screwdriver to tighten the M6 screws on the HDF with the other hand to secure the HDF to the mounting rails of the cabinet.
