Setting Up a Rack-mount System

This section explains how to install a rack-mount InterServe 9000 system in a 19-inch
Intergraph 17 U or 40 U equipment rack. Only technically qualified personnel should install
the system. Computer equipment is secured in the rack along the mounting posts using 7.1
mm diameter mounting holes. The mounting posts have small round markers to designate
each U. There are three mounting holes per U. Further details are found in this section.
The size of racks are designated by their available vertical height and width. Knowing the
size of the rack and equipment you are installing helps determine if the rack is capable of
containing the equipment.
NOTE Physical space is not the only factor to consider when installing equipment. There are facility
and power requirements and load limitations to observe. For more information about power
requirements and load limitations, see the documentation delivered with the system and
equipment.

Safety Guidelines

Before you set up a system, please read and observe the following safety guidelines:
WARNING Avoid injury: The minimum system configuration weighs 29 kg (63 lbs), and the
maximum weighs 44 kg (97 lbs). To avoid injury, two people should lift and insert the
system into the slide assemblies in the equipment rack.
WARNING Work on only one system at a time: Extend only one system at a time from the
equipment rack. Extending more than one system can result in the rack tipping
forward on you.
WARNING Anchor the equipment rack: The equipment rack must be anchored to an unmovable
support to prevent it from falling over when a system on slide assemblies is extended
in front of it. The anchors must be able to withstand a force of up to 113 kg (250 lbs).
You must also consider the weight of any other device installed in the rack.
WARNING Main AC power disconnect: You are responsible for installing an AC power
disconnect for the entire rack unit. This main disconnect must be readily accessible,
and it must be labeled as controlling power to the entire unit, not just to the system(s).
WARNING Grounding the rack installation: To avoid the potential for an electrical shock hazard,
you must include a third wire safety grounding conductor with the rack installation. If
system power cords are plugged into AC outlets that are part of the rack, then you
must provide proper grounding for the rack itself. If system power cords are plugged
into wall AC outlets, the safety grounding conductor in each power cord provides
proper grounding only for the system. You must provide additional, proper grounding
for the rack and other devices installed in it.
