•
Follow the prescribed ESD prevention procedures to avoid damaging the equipment.
Static discharge can cause components to fail completely or intermittently over time.
•
Install the switch in a secure area, so that only authorized personnel can access the
switch.

Site Electrical Wiring Guidelines for J-EX Series Switches
Table 31 on page 65 describes the factors you must consider while planning the electrical
wiring at your site.
WARNING:
It is particularly important to provide a properly grounded and
shielded environment and to use electrical surge-suppression devices.
Table 31: Site Electrical Wiring Guidelines
Guidelines
Site Wiring Factor
If your site experiences any of the following problems, consult
experts in electrical surge suppression and shielding:
•
Improperly installed wires cause radio frequency interference
(RFI).
•
Damage from lightning strikes occurs when wires exceed
recommended distances or pass between buildings.
•
Electromagnetic pulses (EMPs) caused by lightning
damages unshielded conductors and electronic devices.
Signaling limitations
To reduce or eliminate radio frequency interference (RFI) from
your site wiring, do the following:
•
Use twisted-pair cable with a good distribution of grounding
conductors.
•
If you must exceed the recommended distances, use a
high-quality twisted-pair cable with one ground conductor
for each data signal when applicable.
Radio frequency interference
