General Site Guidelines

Efficient device operation requires proper site planning. For the device to operate properly, you must ensure maintenance and proper layout of the equipment, rack or cabinet, and wiring closet.

To plan and create an acceptable operating environment for your device and prevent environmentally caused equipment failures:

  • Keep the area around the chassis free from dust and conductive material, such as metal flakes.
  • Follow the prescribed airflow guidelines to ensure that the cooling system functions properly. Ensure that the exhaust from other equipment does not blow into the intake vents of the device.
  • Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent damaging the equipment. Static discharge can cause components to fail completely or intermittently over time.
  • Install the device in a secure area, so that only authorized personnel can access the device.

Site Electrical Wiring Guidelines

Table 2 describes the factors you must consider while planning the electrical wiring at your site.

 

WARNING: You must provide a properly grounded and shielded environment and use electrical surge-suppression devices.

Table 2: Site Electrical Wiring Guidelines

Site Wiring Factor

Guidelines

Signaling limitations

If your site experiences any of the following problems, consult experts in electrical surge suppression and shielding:

  • Radio frequency interference (RFI) because of improperly installed wires

  • Damage from lightning strikes occurring when wires exceed recommended distances or pass between buildings

  • Damage to unshielded conductors and electronic devices as a result of electromagnetic pulses (EMPs) caused by lightning

Radio frequency interference

To reduce or eliminate RFI from your site wiring, do the following:

  • Use a twisted-pair cable with a good distribution of grounding conductors.

  • If you need to exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal, when applicable.

Electromagnetic compatibility

If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, seek expert advice.

Strong sources of electromagnetic interference (EMI) can cause:

  • Destruction of the signal drivers and receivers in the device.

  • Electrical hazards as a result of power surges conducted over the lines into the equipment.
