The switch can be installed in a two-post or four-post rack. The installation process is identical because the switch attaches to only two posts of a rack.

To mount the switch in a rack, assemble the mounting brackets to the chassis, then attach the brackets to the rack posts. Rack mount accessory kits include the following parts:

• Twomounting brackets

• Six M4x5 flat head Phillips screws.

The following figure displays proper bracket placement for rack mount.

The switch is prepared for flat surface placement by attaching four rubber pads on the bottom of the chassis to prevent the switch from sliding on the table and to protect the surface of the table.

The installation kit provides the following flat surface placement parts.

• Four rubber switch pads

To prepare the switch for placement on a flat surface, peel the four rubber pads from the master sheet and attach one in each indentation near each corner on the bottom of the switch.

The following figure displays the rubber pads placement on the bottom of the switch.

This guide is intended for properly trained service personnel and technicians who need to install the following Arista Networks Data Center Switches:

Upon receiving the switch, inspect the shipping boxes and record any external damage. Retain packing materials if you suspect that part of the shipment is damaged; the carrier may need to inspect them.

If the boxes were not damaged in transit, unpack them carefully. Ensure that you do not discard any accessories that may be packaged in the same box as the main unit.

Inspect the packing list and confirm that you received all listed items. Compare the packing list with your purchase order. Parts List provides a list of components included with the switch.

Criteria to be considered when selecting a site to install the switch.

• Temperature and Ventilation: For proper ventilation, install the switch where there is ample airflow to the front and back of the switch. The ambient temperature should not go below 0°C 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).

   

• Airflow Orientation:
  The fans determine the airflow direction through the switch. The labels indicate the airflow direction.

  Note: The figure shown uses a representative Arista switches to illustrate airflow directions.
  The following figure shows the airflow through the switch:

  

  1	Airflow direction indicator label	3	Fan module handle and release	5	Fan status LED
  2	Fan status LED	4	Airflow direction indicator label	6	Fan module handle and release

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

  To change the airflow direction, change the fan module orientation:

  1. While squeezing the fan module handle, pull the fan module out of the switch.
  2. Rotate the fan module 180°.
  3. Insert the fan module back into the switch.
• 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 Table 3 for information regarding your specific system.
  Important:

  The power input plug-socket combination must be accessible at all times; 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.

   

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

    Important:

    This unit is intended for installation in restricted access areas.

    Cet appareil est prévu pour une installation dans les zones d'accès restreintes.

Tools and equipment are required to install the switch.

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.
