Site Selection
The following criteria should be considered when selecting a site to install the switch:
•
Temperature and Ventilation: For proper ventilation, install the switch where there is ample
airflow
to the front and back of the switch. The ambient temperature should not go below 0° or
exceed
40°C.
Important: To prevent the switch from overheating, do not operate it in an area where the
ambient temperature exceeds 40°C (104°F).
Pour empêcher l’interrupteur de surchauffe, ne pas utiliser il dans une zone où la
température ambiante est supérieure à 40°C (104°F).
•
Airflow Orientation: Determine airflow direction of the four fan modules and two power supply
modules on the rear panel. Fan and power supply module handles indicate airflow direction:
•
Blue Handle: Air Inlet module.
•
Red Handle: Air Exit module.
•
Figure 1: 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. Refer to
Table 3: Switch Specifications (Power Input)
and
Table 4: Switch Specifications (Power Draw)
information regarding your specific system.
