Attaching the Mounting Brackets

Attach two mounting brackets, using the appropriate procedure
for the rack type.

damage during installation, never extend multiple
components installed in the rack at the same time. A rack
may become unstable if more than one component is
extended for any reason.

the bracket. Ensure that the mounting bracket is parallel in the rack
from front to back.
