3.2.1 Ethernet RJ-45 Socket
The ethernet interface on the SMV is an RJ-45 Ethernet socket used to communicate with a host via
Ethernet TCP/IP. Table 2 identifies the terminals and describes the function of each.

The status LEDs integrated in the RJ-45 socket indicate link and activity. The green LED indicates whether
a link is established with another network device. The yellow LED indicates link activity and flashes when
data is received by the EtherNet/IP module.
3.2.2 Grounding
The SMV EtherNet/IP module must be gounded. Attach the ground wire/lug from the module to one of the
the chassis ground screws on the drive as illustrated in Figure 7.
