A-4 Warnings and Precautions!
Rack 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 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 first, 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
servicing 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.
Lithium Battery Precaution
This switch may contain a lithium battery. There is a danger of explosion if the battery is
incorrectly replaced.
• Installing the battery upside-down may reverse the polarities and cause the battery
to explode.
• Replace the battery only with the same or equivalent type recommended by the
manufacturer.
• Dispose of used batteries according to the manufacturer’s instructions.
• Do not damage the battery in any way, a damaged battery may release hazardous
materials into the environment.
