Installation Guide

Provide enough space in front of and behind the switch so that you can service it easily. Allow a
minimum of 48 inches (122 cm) in front of the rack and 30 inches (76 cm) behind the rack.
Some ExtremeSwitching switches give you the option of choosing the airflow direction: front-to-back or
back-to-front. If your switch has internal power supplies, make sure they have the same airflow direction
as the fans in the switch.
Other switches support airflow in only one direction. If your switch model supports only front-to-back
airflow and requires the purchase of internal power supplies, make sure that the power supplies are for
front-to-back ventilation airflow.
The following items are provided with ExtremeSwitching switches:
•
Screws for attaching mounting brackets to the switch housing.
•
Two rack mounting brackets adaptable for either a front-mount or mid-mount installation.
