Confirming installation preparations
Before you install the switch, verify that:
•
You have read " Preparing for installation " carefully and the installation site meets all the

{
The rack is sturdy and securely grounded.
{
No debris exists inside or around the rack.
{
Choose a correct rack mounting position for the switch. Make sure the heaviest device is placed
at the bottom of the rack.
{
The total height of the switches to be installed is no higher than the available installation height
of the rack, and enough clearance is reserved for cable routing.
•
If you are mounting the switch on a workbench, make sure the workbench is sturdy and securely
grounded.
• The switch is ready for installation and has been carried to a place near the installation site and
convenient for moving.
