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).

airflow direction is not compatible with the installation site, contact your sales representative.

Install the switch in a 19" rack or cabinet. The switch height is 2 RU. The accessory
kit provides mounting brackets for four-post racks. Contact your sales representative to obtain
two-post mounting brackets.
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.
