Environmental Requirements

Ensure adequate spacing between racks using the information in the following table. Keep all of the
vents clear of obstructions, including dust and foreign conductive material, and away from the exhaust
ports of other equipment.

When installing a component, use any available ejector levers or captive installation screws to
properly seat the bus connectors in the backplane or midplane. These devices prevent accidental
removal, provide proper grounding for the system, and help to ensure that bus connectors are
properly seated.
When removing a component, use any available ejector levers or captive installation screws to
release the bus connectors from the backplane or midplane.
Handle carriers by available handles or edges only; avoid touching the printed circuit boards or
connectors.
Place a removed component board-side-up on an antistatic surface or in a static shielding container.
If you plan to return the component to the factory, immediately place it in a static shielding
container.
Avoid contact between the printed circuit boards and clothing. The wrist strap only protects
components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Never attempt to remove the printed circuit board from the metal carrier.
