5. Depending on the network topology, do one of the following:
•
Star Network Topology—Route the other end of the Ethernet cable
from the network through the bottom of the drive, and insert its cable
plug into the option module’s ENET1 or ENET2 network port.
• Linear or DLR Network Topology—Route the other end of the
Ethernet cable from the network through the bottom of the first drive,
and insert its cable plug into the option module ENET1 network port.
To connect to the second drive, attach another Ethernet cable between
the first drive’s option module ENET2 network port and the second
drive’s option module ENET1 network port.
To connect additional drives, repeat these daisy-chain connections in
the same way.
