Figure 7 shows the pinout for the RJ-45 Ethernet port (J2). Note that some Ethernet con-
nectors are numbered in reverse to the order used here.
Figure 7. RJ-45 Ethernet Port Pinout
The RJ-45 connector is shielded to minimize EMI effects to/from the Ethernet signals.
Three Ethernet status LEDs are located beside the RJ-45 Ethernet jack: ACT , LINK , and
SPEED
. The yellow ACT LED at DS1 indicates network activity. The green LINK LED at
DS2 indicates that the RCM3305/RCM3315 is connected to a working network. The
green
SPEED
LED at DS4 is on to indicate when the RCM3305/RCM3315 is connected
to a 100Base-T Ethernet connection.
