Distinguishing Between Chassis with Forward and Reverse Airflow
No black stripe indicates forward airflow.
Disconnect all power and external cables before lifting the switch.
Ensure that your footing is solid and the weight of the switch is evenly distributed between your feet.
Lift the switch slowly, keeping your back straight. Lift with your legs, not with your back. Bend at
the knees, not at the waist.
Record the information listed in
install and configure the switch.
Ensure that there is adequate space around the switch to allow for servicing the switch and for
adequate airflow (Appendix B, "Technical Specifications"
requirements).
Ensure that the air-conditioning meets the heat dissipation requirements listed in
"Technical Specifications."
Ensure that the switch is going to be positioned so that it takes in air from a cold aisle and exhausts
air to the hot aisle. If there is a black stripe across the front of these modules, they have forward
airflow and must be positioned with the fan tray and power supplies in a cold aisle. If there is a black
stripe across the front of these modules, they have reverse airflow and must be positioned with the
port connections in a cold aisle.
Ensure that the cabinet or rack meets the requirements listed in
Specifications."
Jumper power cords are available for use in a cabinet. See the
page C-8.
Ensure that the chassis can be adequately grounded. If the switch is not mounted in a grounded rack,
we recommend connecting both the system ground on the chassis and the power supply ground
directly to an earth ground.
