Chapter 2 Preparing for Installation
Preparing Your Site for Installation
Preventing Damage from Electrostatic Discharge
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs
when electronic components are handled improperly and can result in complete or intermittent failures.
• Always follow ESD-prevention procedures when removing and replacing components. Verify that
the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, making
sure that it makes good skin contact. Connect the grounding clip to an unpainted surface of the
chassis frame to safely ground ESD voltages. To properly guard against ESD damage and shocks,
the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by
touching the metal part of the chassis.
• Periodically check the resistance value of the antistatic strap, which should be between 1 and 10
Mohms.
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.
Note that:
• Bad plant wiring can result in radio frequency interference (RFI).
• Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal
drivers 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.
Covering Empty Slots
Ensure that all cards, faceplates, and covers are in place. Blank faceplates and cover panels are used to:
• Prevent exposure to voltages and currents inside the chassis.
• Help contain electromagnetic interference (EMI) that might disrupt other equipment.
• Direct the flow of cooling air through the chassis.
Preparing Your Site for Installation
Make sure your site is prepared properly before beginning installation.
Environmental
When planning your site layout and equipment locations, keep in mind the precautions described in this
section to help avoid equipment failures and reduce the possibility of environmentally caused
shutdowns. If you are currently 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 IE2100 Series.
