3.2 CONNECTING THE 10/100BASE-T ETHERNET INTERFACE
The shielded RJ-45 port labeled
Ethernet
is the Auto-MDIX10/100Base-
T interface. This port is designed to connect directly to a 10/100Base-T
network. Figure 5 shows the signal/pin relationships on this interface.
You may connect this port to a hub or PC using a straight through or
crossover cable that is up to 328 ft long.

3.3 CONNECTING POWER
The Model 2172R does not have a power switch, so it powers up as soon
as it is plugged in.
An external AC or DC power supply is available separately. This connec-
tion is made via the barrel jack on the rear panel of the Model 2172R. No
configuration is necessary for the power supply (See Appendix B for
domestic and international power supply and cord options). DC power
(supplied via the power supply jack to the 2172R) must meet the follow-
ing requirements; DC power supplied must be regulated +5VDC ±5%,
1.0A minimum. Center pin is +5V. The barrel type plug has a 2.5/5.5/
10mm I.D./O.D./Shaft Length dimensions.
The Interconnecting cables shall be acceptable for
external use and shall be rated for the proper applica-
tion with respect to voltage, current, anticipated tem-
perature, flammability, and mechanical serviceability.
