Preparation

This section describes the initial set up and preparation for installing the routers.

This section discusses the following topics:

Site Selection

Consider the following criteria when selecting a site to install the router in a Data Center environment:

  • Temperature and Ventilation: For proper ventilation, install the router with ample airflow to the front and back of the router.

     

    Important:

    To prevent the device from overheating, do not operate it in an area where the ambient temperature exceeds 104°F (40°C).

     

    Pour empêcher l’interrupteur de surchauffe, ne pas utiliser il dans une zone où la température ambiante est supérieure à 104°F (40°C).

     

  • Airflow Orientation: The fans and PSUs determine the airflow direction through the router. The color of the visible handles or labels indicates the airflow direction.
    • Red Handle: The red handle represents the air exit module. The following figure shows the airflow direction through the router with an air exit module.

    Orient the router so airflow goes from the cooler to the hotter aisle.

     

     

  • Rack Space: Install the router in a 19" rack or cabinet. The accessory kit provides mounting brackets for two-post and four-post racks.

    When mounting the router in a partially filled rack, load the rack from bottom to top, with the heaviest equipment at the bottom. If the router is the only item in the rack, load it at the bottom.

     

  • Power Requirements: Each router and power supply model has different power requirements. For information regarding your specific system, refer to Specifications.

    Refer to the Cable the Router section for power cable requirements.

     

    Important:

    The power input plug-socket combination must be accessible at all times, as it provides the primary method of disconnecting power from the system.

     

    La combinaison de la puissance-prise d’entrée doit être accessible en tout temps; Il fournit le principal moyen de coupure d’alimentation du système.

     

     

    Important:

    All power connections must be removed to de-energize the device.

     

    Toutes les connexions d’alimentation doivent être enlevées pour hors tension l’appareil.

     

  • 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 the following guidelines are met:

    • Clearance areas to the front and rear panels allow for unrestricted cabling.

    • All front and rear panel indicators can be easily read.

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

Tools and Parts Required for Installation

Each router comes with an accessory kit containing the parts required to install. In addition to the accessory kit, the following tools are required to install the router:

Four-post Rack

  • #1 and #3 Phillips head screwdrivers (this may differ based on supplied accessories).
  • Screws or rack-mounting nuts and bolts.

Two-post Rack

  • #1 and #3 Phillips head screwdrivers (this may differ based on supplied accessories).
  • Screws or rack-mounting nuts and bolts.

     

The accessory kit should include screws for attaching the router to an equipment rack. When installing the router to an equipment rack with unthreaded post holes, nuts and bolts are also required to secure the router to the rack posts.

Electrostatic Discharge (ESD) Precautions

Observe these guidelines to avoid ESD damage when installing or servicing the router:

 

Important:

DO NOT open the router case. There are no user-serviceable parts inside. Entrust any repair to a qualified technician.

 

N’ouvrez PAS le boîtier du routeur. Il n’y a AUCUNE pièce réparable par l’utilisateur à l’intérieur. Confiez toute réparation à un technicien qualifié.

 

  • Assemble or disassemble the equipment only in a static-free work area.
  • A conductive work surface (such as an anti-static mat) dissipates static charge.
  • Wear a conductive wrist strap to dissipate static charge accumulation.
  • Minimize handling of assemblies and components.
  • Keep replacement parts in their original static-free packaging.
  • Remove all plastic, foam, vinyl, paper, and other static-generating materials from the work area.
  • Select tools that do not create ESD.
