Precautions for Rack
Installation and Use
This chapter explains the precautions for rack transportation, installation, and use.
1.1
Installation Site Precautions
WARNING
CAUTION
• Never place the rack in an unstable location subject to excessive vibrations (over
0.25G), or a location that is not level. Doing so may cause the rack to tip over,
resulting in serious injury.
Make sure the rack or rack-mount unit is fixed as a countermeasure against
excessive vibrations over 0.25G.
• Make sure the rack is installed on a surface with adequate load-bearing capacity.
Maximum loads associated with the rack may exceed 300 kg (Maximum load
capacity of 40U is 1000kg).
• Secure the installation area to ensure normal operation and maintenance of the
rack system.
• To reduce the risk of failure, fire, or electric shock, do not place metal objects or
containers bearing water, such as vases, flowerpots, or drinking glasses, on or
near the rack.
• Avoid placing the rack in locations subject to oil vapors or excessive humidity or
dust, or having poor ventilation, or locations where inflammable materials are
stored. Storage or use of the rack in such areas may lead to failure, fire, or
electric shock.
• To avoid risk of failure, never install the rack in locations subject to high
temperatures, including areas near heaters or in direct sunlight. Do not install the
rack in locations where temperatures drop below 10°C.
• Always confirm that rack openings such as ventilation vents are clear.
Covering ventilation vents may lead to failure or fire because the inside of the
rack becomes hot.
