CAUTION:
Potential equipment damage: Do not exceed the maximum allowable
weight (77.1 kg [170 lb]) and U-height (6U) for equipment in the rack area
of this library.
Observe the following safety and handling precautions when you are installing
equipment into the library’s rack:
• 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 rack-installed equipment will remain powered-on.
• 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 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.
• 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.
