Note: If the chassis being removed was factory installed, additional shipping
braces were added for stability during shipment. These consist of
L-brackets and flat mounting plates. The mounting plates are attached on
either side at the blower end of the chassis. The L-brackets secure the
mounting plates to the cabinet vertical rails. Detach the L-brackets from
the mounting plates and the cabinet rails before removing the chassis
from the cabinet. If you anticipate that the cabinet with an installed
chassis may be shipped to another location in the future, it is
recommended that you attach these shipping brackets to any
replacement chassis. Take note of how the brackets are assembled and
attached when you remove them from the old chassis.
