Environmental Requirements - NEC Express5800 1080Xd User Manual

(c) If it is unavoidable to share the security grounding electrode and the computer
grounding electrode, connect them near the ground. Addition of leakage current from
the security grounding electrode will result in activating the leakage breaker. The
grounding is also aimed at preventing the flow of noises from other devices into
computers.
(d) When using the steelwork of the building as a substitute for the grounding electrode,
connect the cable as close as possible to the foundation of the building.
(e) Make sure that the grounding conductor is routed to the power distribution panel.

Environmental Requirements

The Express5800/1000 Series servers are designed to operate in a computer-room
environment. When you select a location, you should:
Make sure the location has a sturdy, level floor, and is not subject to vibration.
!
Make sure the location is away from high-traffic areas.
!
Make sure the location is clean and free from dust, smoke, or other airborne
!
contaminants.
Make sure the location does not have significant temperature changes. Choose a
!
location where the temperature does not vary more than 18°F (7.78°C) per hour.
Make sure the location does not have significant humidity changes. A location
!
with approximately 40 percent humidity can prevent problems stemming from
electrostatic discharge.
Make sure the location has adequate space in front of and behind the rack. You
!
must be able to connect cables and service the parts of your hardware. It also
needs adequate airflow for cooling.
If security for the Express5800/1000 Series server is important, you should address this
issue during site planning. Planning and implementing security for the hardware, before its
installation, will save disrupting the hardware and its users at a later time.
Table 8 provides information on operating and storage temperature and humidity
specifications for the Express5800/1000 Series server hardware components. Make sure
your environment meets the narrowest range of specifications in the table.
