Fans And Airflow; Storing Components - Dell Force10 E300 Installing And Maintaining

Fans and Airflow

Your E300 chassis contains one field-replaceable fan tray. Air flows through the E300 system toward the
fans and is exhausted on the fan side of the chassis. Air circulates from the right side to the left. Minimum
air flow is 665 cubic feet per minute (CFM).
For fan access, maintenance and proper ventilation, position a chassis in an equipment rack (or cabinet)
with least six inches (16 cm) of clearance around the side intake and exhaust vents and a wall. For free air
flow between two E300s or an E300 and another side-by-side airflow chassis, position the chassis at least
12 inches (30.5 cm) apart. For instructions on replacing the fan try, see
Tray" on page 45.

Storing Components

CAUTION:
Do not transport a E300 chassis with the components (line cards, power modules, RPMs, and SFMs) fully
installed in the chassis. Place the components in their original protective shipping packaging and insert them back into
their original shipping position. Shipping components installed, without their protective packaging, may damage the
components and the chassis backplane.
If you do not install your E300 System and components immediately, Dell Force10 recommends you
properly store components and all extra field-replaceable parts (spares) until you are ready to install
them.
Follow these indoor storage guidelines:
• Storage temperature should remain constant ranging from 41° to 104°F (5°C to 40°C)
• Non condensing relative humidity should be maintained with 5 to 95%.
• Store on a dry floor, away from direct sunlight, heat, and air conditioning ducts.
• Store in a dust-free environment.
