The following topics are covered in this section:

 

Note: A four-post rack mount is recommended for all routers. Use the rack-mount parts included with the router for mounting.

Four-post Rack Mount

This section provides instructions for mounting the router in a four-post rack.

The router mounts onto a four-post rack by assembling two rails onto the rear posts, sliding the router onto the rails, and securing the router to the front posts.

The installation kit provides the following four-post mounting parts:
  • Two six-hole mounting brackets
  • Two rail rods
  • Two rail slides

     

The rail rods and rail slides assemble into two identical slide rails.

Each chassis side has attachment pins that align with bracket holes. Pin orientation is symmetric and equidistant, supporting bracket placements where the flange is flush with the front panel, flush with the rear panel, or not flush with either panel. Each bracket hole includes a key opening for placing the bracket flush with the chassis and then locking it into place.

 

Important:

Attachment pins must engage at least five of the six bracket holes.

 

Goupilles de fixation doivent être lock au moins cinq des trous du six support.

 

 

The following figure displays proper bracket mount configuration examples for four-post mounting.

  1. Align the mounting brackets with the attachment pins to obtain the desired mounting position.
  2. Place the bracket flush to the chassis with the attachment pins protruding through the key openings.
  3. Slide the bracket toward the front flange until the bracket clip locks with an audible click.

    To remove the mounting bracket from the chassis, lift the front edge of the mounting bracket clip with a flat-head screwdriver and slide the bracket away from the front flange (opposite from the installation direction).

     

Assembling the Rails onto the Equipment Rack

Rail rods and rail slides assemble into two identical rails. Each rail connects a front post to a rear post. When installing the rails, the router slides onto the rails and into the rack. Each bracket includes a screw that attaches the router to the rail.

Each end of an assembled rail contains two rack plugs. Insert the plugs into the rack slots to install the rails into a rack. When installing rails into rack posts with threaded or rounded holes, remove all plugs on both sides of the assembled rails and install them with bolts that fit the rack.

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 direction of the airflow through the router with an air exit module.

       

      Figure 1. Air Exit Modules

       

    Orient the router so that 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 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 that 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 in 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.
