Preventing EMI

When you run wires for any significant distance in an electromagnetic field, electromagnetic
interference (EMI) can occur between the field and the signals on the wires.
Bad plant wiring can result in radio frequency interference (RFI).
Note
Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers
Note
and receivers in the system, and can even create an electrical hazard by conducting power surges through
lines and into the system.
To predict and remedy strong EMI, consult RFI experts.

Preparing Your Site for Installation

This section describes the requirements your site must meet for safe installation and operation of your
MARS Appliance. Ensure that your site is properly prepared before beginning installation.

Environmental

When planning your site layout and equipment locations, remember the precautions described in this
section to help avoid equipment failures and reduce the possibility of environmentally caused
shutdowns. If you are experiencing shutdowns or unusually high errors with your existing equipment,
these precautions will help you isolate the cause of failures and prevent future problems.
Use the following precautions when planning the operating environment for your MARS Appliance:
•
•
•
Also, verify that make sure your environment is suitable for the MARS Appliance:
OL-14672-01
When unpacking a static-sensitive component from its shipping carton, do not remove the
component from the antistatic packing material until you are ready to install the component in your
computer. Just before unwrapping the antistatic packaging, be sure to discharge static electricity
from your body.
When transporting a sensitive component, first place it in an antistatic container or packaging.
Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and
workbench pads.
Always follow the ESD-prevention procedures described in
damage to equipment. Damage from static discharge can cause immediate or intermittent equipment
failure.
Make sure that the chassis cover is secure. The chassis allows cooling air to flow effectively within
it. An open chassis allows air leaks, which could interrupt and redirect the flow of cooling air from
internal components.
Electrical equipment generates heat. Ambient air temperature might not be adequate to cool
equipment to acceptable operating temperatures without adequate circulation. Make sure that the
room in which you operate has adequate air circulation.
