Read and understand the clearance requirements for the chassis to ensure
adequate ventilation.
Prepare the equipment racks by measuring and marking space for each
router and plenum you plan to install.

When installing the system on a table top or in any other freestanding mode,
be sure to leave enough space around the system for adequate ventilation.
Position the router with easy access to the connections that it needs for power,
local communications, and remote communications.
