  • Page 6: Receiving And Inspecting The Equipment

    Receiving and Inspecting the Equipment 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.

    Airflow Orientation: The fans and PSUs determine the airflow direction through the switch. The color of the visible handles or labels indicate the airflow direction. Note: The figures shown use representative Arista switches to illustrate airflow directions. Refer to Rear Panel to determine the airflow for your switch.
  • Page 14 • Red Handle: Air Exit module. The following figure shows the airflow through the switch with air exit modules: Figure 2: Air Exit Module 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 modules to circulate air in the opposite direction.

    Rack Mounting the Switch The following figures show the correct bracket attachment for a center mount. Figure 5: Attaching the Mounting Brackets to the Switch Chassis To remove the mounting bracket from the chassis, lift the front edge of the mounting bracket clip with a flathead screwdriver and slide the bracket away from the front flange (opposite from the installation direction).
  • Page 20 • 2 rail-rods • 2 rail-slides The rail-rods and rail-slides assemble into two identical slide-rails. Note: For longer chassis, there are two additional pieces to help the switch engage with the rails earlier. 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 switch panel, flush with the rear panel, or not flush with either panel.

    3.5.3 Expanding the Rails The rail is a two-piece mechanism. The rail length is adjusted by sliding the rail-rod inside the rail- slide. The rail clip prevent extension of the rail beyond the maximum supported distance between front and rear rack posts. When the rail is contracted, the rail clip is closest to the slide end. The rail is initially contracted and must be expanded to attach onto the rack.
