Electrical Requirements - NEC Express5800 1080Xd User Manual

Electrical Requirements

You should consider installing a separately derived power system for your
Express5800/1000 Series server. This ensures that you can control the hardware grounding,
with all grounds brought to a single point, and that uncontrolled equipment, such as coffee
makers or floor polishers, cannot be plugged into the same power source as the server
hardware.
If you do not create a separately derived power system, you need to make sure the power
outlets you use are from the same distribution panel. This helps to prevent the occurrence of
ground loops that can be caused by plugging equipment into power sources with different
ground potentials.
For the UPSs, you'll need to run separate 120-volt, 30-amp power lines with a NEMA L5-
30R receptacle, or 230-volt, 30-amp power lines with an IEC C-19 receptacle, to the
location where you are installing the server. If you run more than one power line because
you have more than one UPS, you must make sure the power lines come from the same
distribution panel.
You should have all the electrical work at your site done by a licensed electrician. All the
electrical changes must meet country, state, and local electrical codes.
As you choose the location for your Express5800/1000 Series server, keep these electrical
requirements in mind:
Make sure there is adequate, dedicated power for the UPSs that are part of your
!
server environment.
Make sure your location is away from major electrical equipment such as motors,
!
air conditioners, or elevators.
Make sure the location is not subject to electrostatic buildup.
!
Plug only your server equipment into the power strips. Do not plug in coffee
!
makers, radios, lights, or other non-server devices.
