SRX210 Services Gateway Hardware Guide

Table 46: Site Electrical Wiring Guidelines for the Services Gateway (continued)

Site Wiring Factor

Guideline

Radio Frequency

To reduce or eliminate the emission of RFI from your site wiring:

Interference (RFI)

Use twisted-pair cable with a good distribution of grounding

 

 

conductors.

 

Use a high-quality twisted-pair cable with one ground conductor for

 

each data signal when applicable, if you must exceed the

 

recommended distances.

Electromagnetic

Provide a properly grounded and shielded environment and use electrical

Compatibility (EMC)

surge-suppression devices.

Strong sources of electromagnetic interference (EMI) can cause the following damage:

Destroy the signal drivers and receivers in the device

Conduct power surges over the lines into the equipment, resulting in an electrical hazard

NOTE: If your site is susceptible to problems with EMC, particularly from lightning or radio transmitters, you may want to seek expert advice.

CAUTION: To comply with intrabuilding lightning/surge requirements, the intrabuilding wiring must be shielded. The shielding for the wiring must be grounded at both ends.
