A.4 Warnings and Precautions!
Rack Precautions
• Ensure that the leveling jacks on the bottom of the rack are fully extended to the oor with
the full weight of the rack resting on them.
• In a single rack installation, stabilizers should be attached to the rack.
• In multiple rack installations, the racks should be coupled together.
• Always make sure the rack is stable before extending a component from the rack.
• You should extend only one component at a time - extending two or more simultaneously
may cause the rack to become unstable.
General Precautions
• Review the electrical and general safety precautions that came with the components you
are adding to your switch (if any).
• Determine the placement of each component in the rack before you install the rails.
• Install the heaviest server components on the bottom of the rack rst, and then work up.
• Use a regulating uninterruptible power supply (UPS) to protect the servers and switches
from power surges, voltage spikes and to keep your system operating in case of a power
failure.
• Always keep the rack's front door and all panels and components closed when not servic-
ing to maintain proper cooling.
• Do not remove the cover of the switch, there are no user-serviceable components inside.
Take unit to service center for repairs and servicing.
• Disconnect all power cords before servicing.
Warning: Slide/rail mounted equipment is not to be used as a shelf or work space.
