Installing the switch

IMPORTANT:
Keep the packages of the switch and the components for future use.

Confirming installation preparations

Before you install the switch, verify that:
•
You have read "Preparing for installation" carefully and the installation site meets all the
requirements.
•
A 19-inch rack is ready for use and the rack has enough space to accommodate the switch.
For information about how to install a rack, see the rack installation guide.
•
The rack is sturdy and reliably grounded.
•
No debris exists inside or around the rack.
•
The rack can provide power as required by the switch. For information about the system power
consumption, see "Module power consumption and system power consumption." For power
supply specifications such as power input mode and rated input voltage, see "Power supplies."
•
The total height of the switches to be installed is not higher than the available installation height
of the rack and enough clearance is reserved for cable routing.
•
The switch is ready for installation and has been carried to a place near the rack and convenient
for moving.
