6 Supported Fiber Optic Cables
Siemens also does not recommend using copper Ethernet ports to interface with devices in the field across
distances that could produce high levels of ground potential rise (i.e. greater than 2500 V), during line-to-ground
fault conditions.

Ingress Protection
IEC International Standard 60529 (Edition 2.1: 2001-02) is a "classification of degrees of protection provided
by enclosures as a system for specifying the enclosures of electrical equipment on the basis of the degree of
protection provided by the enclosure." These ratings are determined by specific tests.
The RUGGEDCOM RS969 Industrial Ethernet Switch is manufactured and tested to IP67 standards. With an IP67
rating a product will be "dust tight" and remain completely sealed when immersed in water to a depth of 1 meter
for 1 hour (IEC 60529).
These caps completely seal off unused ports on the IP67 Industrial Ethernet Switch. It has an IP67 rated seal that
keeps out all contaminants like dirt, oil, and water.
