  1. Select and prepare the installation site Site Selection.
  2. Assemble the installation tools listed Tools and Parts Required for Installation.
  3. Attach the mounting brackets and install the switch in an equipment rack Rack Mounting the Switch.
  4. Connect the switch to the power source and network devices Cabling the Modular Switch.
  5. Configure the switch Configuring the Modular Switch.
    Important: Class 1 Laser Product: This product has provisions to install Class 1 laser transceivers that provides optical coupling to the communication network. Once a Class 1 laser product is installed, the equipment is a Class 1 Laser Product. The customer is responsible for selecting and installing the Class 1 laser transceiver and for insuring that the Class 1 AEL (Allowable Emission Limit) per EN/IEC 60825, CSA E60825-1, and Code of Federal Regulations 21 CFR 1040 is not exceeded after the laser transceiver have been installed. Do not install laser products whose class rating is greater than 1. Refer to all safety instructions that accompanied the transceiver prior to installation. Only Class 1 laser devices certified for use in the country of installation by the cognizant agency are to be utilized in this product.
