Install the System in a Rack
Use the rack-mount hardware included with your ReadyNAS or your expansion disk array to
install it in a rack.
Note that the left and right rails are not identical. The left rail is marked with a sticker bearing
the letter L, and the right rail is marked with a sticker bearing the letter R. Each rail has an outer
rail, a middle rail, and an inner rail. Do not exchange the inner rails of the left and right rails.
While installing the system into a rack, keep the ball bearing shuttle locked at the front of the
middle rail.
A minimum of two people are required for safe installation of the system.
DANGER
:
A unit with installed drives can weigh more than 34 kg (75 pounds). To avoid injury or damage
to the equipment, perform the rack-mount installation with appropriate assistance. We recommend
installing the system into the rack before installing the disks.
Precautions
Follow these rack-mount precautions:
• Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with
the full weight of the rack resting on them.
• In single-rack installations, attach stabilizers to the rack. In multiple-rack installations,
couple the racks together.
• Always make sure the rack is stable before extending a component from the rack.
• Extend only one component at a time. Extending two or more simultaneously might cause
the rack to become unstable.
• Review the electrical and general safety precautions that came with the components you
are adding to your chassis.
• Determine the placement of each component in the rack before you install the rails.
• Install the heaviest components on the bottom of the rack first, and then work up.
• Use a regulating uninterruptible power supply (UPS) to protect the ReadyNAS from power
surges and voltage spikes and to keep your system operating in case of a power failure.
• Allow any hot-plug drives and power supply modules to cool before touching them.
• Always keep the rack’s front door and all panels and components on the servers closed
when not servicing them to maintain proper cooling.
