Preparation

Site Selection

Describes the location specifications.

Consider the following criteria when selecting a site to install the switch:

Floor Space: Install the switch in an area that provides adequate clearance for removing front and rear components. The following figure displays switch clearance requirements.
Figure 1. Switch Component Removal Footprint

  1. Temperature and Ventilation: For proper ventilation, install the switch with ample airflow to the front and back of the switch. The temperature should not go below 0° or exceed 40°C.
    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).

     

  2. Airflow Orientation: Determine the airflow direction of the fan modules and power supply modules. Fan and power supply module handles indicate airflow direction:
    • Blue Handle: Air Inlet module.
    • Red Handle: Air Exit module.

 

The Front Panels display power supply module locations on the front panel. The Rear Panels display fan module locations on the rear panel (DCS-7316 switches may also contain rear panel power supply modules). Verify the airflow direction of all modules satisfies these criteria:
  • All rear panel modules have the same color handles.
    • All front panel modules have the same color handles.
    • Rear panel modules must have different color handles than front panel modules.

       

    Orient the switch to ensure the air intake modules face the cool aisle. If the airflow direction is incompatible with the installation site, contact your sales representative to obtain modules that circulate air in the opposite direction.

     

  • Rack Space: Install the switch in a 19" rack or cabinet. The switch height depends on the switch model, as specified in the Table 1 - 7300 Modular Switch and Component Specifications. Verify that the linecard and supervisor removal clearance (Figure 1 - Switch Component Removal Footprint) provide adequate space for the power and data cables that connect to the switch.

    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.

    The accessory kit provides mounting brackets for four-post racks. Contact your sales representative to obtain two-post mounting racks.

     

  • Power Requirements: Power requirements vary by switch. Refer to Table 1 - 7300 Modular Switch and Component Specifications for information regarding your specific system.

    Multiple circuits provide redundancy protection. The switch uses power cables that have an IEC-320 C19 plug. The accessory kit provides IEC-320 C19 to C20 power cables.

    Important:

    All power input plug-socket combinations must be accessible at all times; they provide the primary method of disconnecting power from the system.

     

    Toutes les combinaisons de fiche-prise d’entrée de puissance doivent être accessibles en tout temps; ils fournissent le principal moyen de coupure d’alimentation du système.

     

  • 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:
    • Clearance areas to the front and rear panels allow for unrestricted cabling.
    • All front and rear panel indicators can be easily read.
    • AC power cords can reach from the AC power outlet to the connectors on the front panel.
      Important:

      Disconnecting power to all input sockets is required to power off the unit completely.

       

      Coupure d’alimentation sur toutes les entrées il faut pouvoir complètement l’appareil hors tension.
