Safety Considerations for Installing Switches
Read the information in this chapter thoroughly before you attempt to install or remove an Extreme
Networks switch.
Ensure that proper ESD (electrostatic discharge) controls are in use before switch maintenance is
performed. This includes but is not limited to wrist straps that are grounded to the switch housing and
earth grounds.
Warning
Connect the chassis ground wire before you connect any DC power cables.
Disconnect the ground wire after you disconnect all DC power cables.
Take care to load the equipment rack so that it is not top-heavy. Start installing equipment at the
bottom of the rack and work up.
Do not cover vents that would restrict airflow.

What You Will Need for the Installation

Ensure that you have followed the guidance in "Preparing to Install," and ensure that you have the
appropriate people and tools on hand.
Installing Extreme Networks switches is easiest when there are two people to maneuver the switch and
attach mounting hardware.
Provide enough space in front of and behind the switch so that you can service it easily. Allow a
minimum of 122 cm (48 in) in front of the rack and 76 cm (30 in) behind the rack.
If your switch has internal power supplies, make sure they have the same airflow direction as the fans in
the switch.
Check Quick Reference Guide for your switch model to see what hardware is provided in the switch
packaging. Most Extreme Networks switches come with the following hardware:
•
Two rack mounting brackets (ears) adaptable for either a front-mount or mid-mount installation.
•
Two long mounting brackets (rails) or slider kits for mounting in a four-post installation.
•
Screws for attaching mounting hardware to the switch housing.
