Preparation

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

The following topics are covered in this section:

Site Selection

The following criteria should be considered when selecting a site to install the switch:

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

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

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

  • Airflow Orientation: The fans and PSUs determine the airflow direction through the switch. The color of the visible handles or labels indicates the airflow direction.

    Orient the switch so that airflow flows from the cooler to the hotter aisle. If the airflow direction is not compatible with the installation site, reorient the fan modules to circulate air in the opposite direction.

  • Rack Space: Install the switch in a 19" rack or cabinet. The switch height is 1 RU. The accessory kit provides mounting brackets for two-post racks.

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

  • Power Requirements: Power requirements vary by switch and power supply model. Refer to Specifications for information regarding your specific device.

    Important: The power input plug-socket combination must be always accessible; 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 unit.

    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 are visualizable.

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

Tools and Parts Required for Installation

Each device has an accessory kit containing the parts required to install the switch. In addition to the accessory kit, the following tools and equipment are required to install the switch:

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 does not include screws for attaching the switch to the equipment rack. When installing the switch into an equipment rack with unthreaded post holes, nuts are also required to secure the switch to the rack posts.

Electrostatic Discharge (ESD) Precautions

Observe these guidelines to avoid ESD damage when installing or servicing the switch.

  • Assemble or disassemble equipment only in a static-free work area.

  • Use a conductive work surface (such as an anti-static mat) to dissipate 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.

  • Use tools that do not create ESD.
