Ensure that you have followed the guidance in Site Preparation, and ensure that you have the appropriate people and tools on hand.
Installing 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. Ensure that a minimum of 122 cm (48 in) in front of the switch and 76 cm (30 in) behind the switch.
Check the Quick Reference Guide for your switch model to see what hardware is provided in the switch packaging.
