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.
Figure 3: Airflow Direction Labels
displays fan and power supply module locations on the rear panel.
Their red handles indicate that they are air exit modules. Verify that each module has the same airflow
direction. Base the switch orientation on the airflow direction of the modules to assure the air inlet is
always oriented toward the cool aisle:
•
Air Exit modules: orient the rear panel toward the hot aisle.
•
Air Inlet modules: orient the rear panel toward the cool aisle.
If the airflow direction is not compatible with the installation site, contact your sales representative to
obtain modules that circulate air in the opposite direction.
•
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 and four-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.
