Overview

This section discusses the following topics:

Scope

This guide is for properly trained service personnel and technicians who need to install the following Arista Networks Data Center Switches:
  • DCS-7804
  • DCS-7808
  • DCS-7812
  • DCS-7816
  • DCS-7816L

     

Important: Only qualified personnel should install, service, or replace this equipment.

Seul le personnel qualifié doit installer, service, ou remplacer cet équipement.

Receiving and Inspecting the Equipment

Upon receiving the switch, inspect the shipping boxes and record any external damage. If you suspect that part of the shipment is damaged, retain packing materials; the carrier may need to inspect them.

If the boxes were not damaged in transit, unpack them carefully. Do not discard any accessories that may have been packaged in the same box as the main unit.

Inspect the packing list and confirm that you received all listed items. Compare the packing list with your DCS-7800 Series Modular Switches purchase order. The Parts List provides a list of components included with the switch.

Installation Process

Perform the following steps to install and use the switch:
  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 Switch).
  5. Configure the switch (Configuring the Switch).
     
    Important:

    Class 1 Laser Product: This product has provisions for installing Class 1 laser transceivers that provide 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 ensuring 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 has been installed. Do not install laser products whose class rating is greater than 1. Refer to all safety instructions that accompany the transceiver before 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.

    Produit Laser de classe 1: Ce produit a des dispositions pour installer des émetteurs-récepteurs de laser de classe 1 qui offre de couplage au réseau de communication optique.Une fois un produit laser de classe 1 est installé, l'équipement est un produit Laser de classe 1 (Appareil à Laser de Classe 1).Le client est responsable pour sélectionner et installer l'émetteur/récepteur de laser de classe 1 et pour assurer que la classe 1 AEL (limite d'émission admissible) par EN/IEC 60825, CSA E60825-1, et Code des règlements fédéraux 21 CFR 1040 ne soit pas dépassée après avoir installé l'émetteur/récepteur de laser. Ne pas installer des appareils à laser dont la cote de classe est supérieure à 1.Voir toutes les consignes de sécurité qui ont accompagné l'émetteur-récepteur avant l'installation. Seuls appareils laser de classe 1 certifiés pour une utilisation dans le pays d’installation par l’organisme compétent doivent être utilisées dans ce produit.

    Important:

    Ultimate disposal of this product should be handled in accordance with all national laws and regulations.

    L'élimination finale de ce produit doit être effectuée conformément à toutes les lois nationales etrèglements.
