Cabling Infrastructure
Poorly or incorrectly installed network cabling can cause numerous problems in the Intel®
RSP Sensor network. However small it may appear, a problem with network cabling can
have a catastrophic effect on the operation of the network. Even a small kink in a cable can
cause an Intel® RSP to have intermittent connection with the Gateway, and a poorly crimped
connector may compromise Power over Ethernet (POE) functionality.
If there is existing cabling in an installation, it should be tested first using a Fluke Networks*
LSPRNTR-100 or equivalent device to insure proper RJ-45 connector pin out and Power
over Ethernet (POE) capability before using with to power an Intel® RSP.

Correct Wiring Standards
There are two wiring standards for network cabling: T568a and T568b.
DO NOT COMBINE
T568a and T568b on the same cable!
Figure 12: T-568A vs. T-568B
RJ-45 connectors are designed for either stranded or solid cable, but usually not both.
Ensure use of the correct crimping tool for the specific type of connector. Ethernet cables
have four pairs of color-coded twisted wires (orange, green, blue and brown). These cables
are designed for high-speed data transfer with very little cross talk. It is important that no
more than about 6 mm of the cable is untwisted at either end.
