Installing the Option Module Chapter 2
Connecting the Option
Module to the Network The option module is connected to the network differently depending on the
mode in which the option module is operated.
When Operating in Adapter Mode
1. Remove power from the drive.
2. Remove the drive cover and lift up the drive HIM bezel to its open
position to access the drive control pod.
3. Use static control precautions.
4. Connect one end of the Ethernet cable to the network.
Examples of different EtherNet/IP network topologies are shown in
Figure 3 , Figure 4 , and Figure 5 . For information about linear and device-
level ring (DLR) topologies, see EtherNet/IP Embedded Switch
Technology, publication
ENET-AP005 .

ATTENTION: Risk of injury or death exists. The PowerFlex drive may contain high
voltages that can cause injury or death. Remove power from the drive, and then
verify power has been discharged before connecting the option module to the
network.
IMPORTANT The option module has EtherNet/IP embedded switch technology, and ENET1
and ENET2 network ports to connect to a linear or device-level ring (DLR)
network in a single subnet.
You cannot use ENET1 and ENET 2 network ports as two network interface
cards connected to two different subnets.
