If your site is susceptible to problems with electromagnetic
compatibility (EMC), particularly from lightning or radio

Some of the problems caused by strong sources of
electromagnetic interference (EMI) are:
■
Destruction of the signal drivers and receivers in the
switch.
■
Electrical hazards as a result of power surges conducted
over the lines into the equipment.

AC Power, Connection, and Power Cord Specifications
Detachable AC power cords are supplied with the switch. The appliance coupler at
the female end of the cord inserts into the AC appliance inlet on the faceplate of the
AC power supply. The coupler is type C19 as described by International
Electrotechnical Commission (IEC) standard 60320. The plug at the male end of the
power cord fits into the power source outlet that is standard for your geographical
location.
NOTE: In North America, AC power cords must not exceed 4.5 meters (approximately
14.75 feet) in length, to comply with National Electrical Code (NEC) Sections 400-8
