Preparation

 

The Preparation section discusses the following topics:

Site Selection

 

Consider the following criteria when selecting a site to install the Arista NDR appliance(s):

  • Temperature and Ventilation: For proper ventilation, install the Arista NDR appliance, where there is ample airflow to the front and back of the Arista NDR appliance. Maintain an ambient temperature between 0° and 40°C.

     

    Warning:

    Do not operate the Arista NDR appliance in an area where the ambient temperature exceeds 40°C (104°F) to prevent overheating.

     

    Pour éviter que l'appliance Arista NDR ne surchauffe, ne l'utilisez pas dans une zone où la température ambiante est supérieure à 40 °C (104 °F).

     

     

  • Rack Space: Install the Arista NDR appliance in a 19" rack or cabinet. The accessory kit provides mounting brackets for a four-post rack.

    When mounting the Arista NDR appliance in a partially filled rack, load the rack from bottom to top, with the heaviest equipment at the bottom. Load the Arista NDR appliance at the bottom if it is the only item in the rack.

     

  • Other Requirements: Select a site where liquids or objects cannot fall onto the equipment and foreign objects are not drawn into the ventilation holes. Verify these guidelines are met:
    • Maintain clearance areas in the front and rear panels for unrestricted cabling and switch and control accessibility.
    • All front and rear panel indicators can be easily seen and read.

       

       

      Note: The Status indicators and control functions are shown in Status Indicators Appendix A.

       

       

    • Power cords can reach from the power outlet to the connector on the rear panel.

       

    Warning:

    Remove all power connections to fully de-energize the unit after it is powered off using the power switch.

     

    Toutes les connexions électriques doivent être retirées pour mettre complètement l'unité hors tension après sa mise hors tension à l'aide de l'interrupteur d'alimentation.

     

     

Tools and Parts Required for Installation

 

Each Arista NDR appliance provides an accessory kit containing the parts required to install it. In addition to the accessory kit, the following tools and equipment are required to install the Arista NDR appliance:
  • Screws or rack mounting nuts and bolts
  • Screwdriver
  • Four post rails
  • Phillips head screw driver

 

 

Note: No additional equipment is required for installation into tool-less four-post racks.

 

 

The accessory kit does not include screws for attaching the Arista NDR appliance to the equipment rack. When installing the appliance into an equipment rack with unthreaded post holes, nuts are also required to secure the device to the rack posts.

Electrostatic Discharge (ESD) Precautions

 

Observe these guidelines to avoid ESD damage when installing or servicing Arista NDR appliances:
  • Assemble or disassemble equipment only in a static-free work area.
  • Select a conductive work surface (such as an anti-static mat) to dissipate static charge accumulation.
  • Wear a conductive wrist strap to dissipate any static charge accumulation.
  • Minimize handling of assemblies and components.
  • Keep replacement parts in their original static-free packaging until they can be handled with anti-static precautions.
  • Remove all plastic, foam, vinyl, paper, and other static-generating materials from the work area.
  • Select tools that do not generate ESD.
