• Personnel should take adequate precautions when they are moving a
library that contains rack-installed equipment. The weight of some
rack equipment might alter the height of the library's center of
gravity. This condition might cause the library to tip during a move.
Observe the following safety and handling precautions when you are installing equipment
into the library's rack:
CAUTION:
Potential equipment damage: Do not exceed the maximum allowable
weight (130 kg [300 lb]) and U-height (17U) for equipment in the rack area
of this library.
• Ensure that the equipment has UL listing (listing by Underwriters' Laboratories),
CSA certification (certification by the Canadian Standards Association), and CE
compliance (compliance with the European Council's directives and standards).
• Understand that the library does not supply power to the rack area. So ensure that
the rack-installed equipment has an adequate power source.
Note: If you remove power from the library by using the library's power switch, the
• Follow the manufacturer's guidelines to position, to support, and to fasten the
equipment in the rack.
• Locate the equipment so that it does not block or hinder any ventilation openings in
the library's rack area. For example, do not block library or drive exhaust areas, the
electronic module exhaust area, perforated metal, or other similar ventilation.
• Locate the equipment so that the library doors adequately clear the equipment when
you close them.
• Install the equipment from the bottom of the rack to the top of the rack; StorageTek
recommends that you place the heaviest items near the bottom of the rack.
• Ensure that any equipment that you install within the rack is adequately cooled. The
library's internal ambient temperature should not exceed the recommended operating
temperature. Base cooling considerations upon the power dissipation within the rack
space as well as upon the ambient room conditions that are external to the library.
You must provide cooling for moderate power dissipation within the rack space.
• Ensure that the equipment in the rack does not create an overcurrent
condition, whether equipment is connected directly to the branch circuit or
to a power distribution strip.
• Ensure that the equipment in the rack has reliable earth ground, whether
equipment is connected directly to the branch circuit or to a power
distribution strip.
